Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte!
La guerre contre Bitcoin
Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin.
À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et BitcoinSV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes, souvent jusqu'à un "exit scam" presque garanti, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une cryptomonnaie qui fonctionne comme une machine à états mondiale et permet un déploiement facile de tokens et de contrats intelligents. Mais le protocole Ethereum ne peut pas évoluer, et parmi les milliers de projets lancés, seule une poignée pourrait même être présentés comme pouvant devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales enrichissant les développeurs et escroquant les investisseurs amateurs.
C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners (nom donné pour englober toutes les autres cryptomonnaies) de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant - et c'est là l'ironie! - une prétendue fraude et arnaque présumée qui serait l'existence même de BSV.
Nous devons nous demander pourquoi ?
Quel est le différenciateur clé de BSV?
Pourquoi tous les arnaqueurs se sont-ils unis contre lui?
Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre civile et culturelle qui les dépasse. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève de Bitcoin
Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or il s'agit là du problème de tous les systèmes de paiement électronique précédents, et c'était le seul facteur limitant l'adoption d'une monnaie digitale fonctionnelle. Mais qu'est-ce que le problème de la double dépense ? Pour faire simple, il était impossible de prouver exactement qui possédait quelles unités d'argent sur des registres distribués, de sorte que les utilisateurs ne pouvaient pas avoir confiance dans le système, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé la « preuve de travail ». Il pose la question: qui a utilisé le plus de puissance de calcul pour résoudre des énigmes arbitraires ? ceci afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun des participants. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des nouveaux Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail.
Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds d'un réseau sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils se mettent donc à planter. Sur le jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau. Pour empêcher cela, un plafond de 1 Mo de données par chaque dix minutes de transactions a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin. De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin et le déclencheur de la plus grande guerre civile virtuelle de l'univers de la cryptomonnaie.
Pourquoi est-ce aussi important?
Une seule transaction basique Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto le créateur, a plaidé pour un nombre de transactions du niveau de Visa et bien plus, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen. Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont ​​également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer et de rester le meilleur système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo des blocs.
Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être utilisé pour des envois sauf en grosses quantités de toute façon, selon eux. En décembre 2017 les frais de BTC ont ainsi atteint les $50 par transaction. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par Sybil, et je dirais que BTC est régi par des sybilles à ce jour.
Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin pour des frais infimes, de l'ordre d'un centième ou millième de centime par transaction, afin d'apporter à la population mondiale la liberté monétaire, y compris aux pays les plus pauvres qui sont gardés en dehors du système actuel car considérés comme pas assez profitables pour des entreprises comme Visa.
Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions, ce qui est le cas quand les frais sont à $50 par transaction comme en 2017.
Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé.
Alors quelle est la différence entre ces trois versions ?
BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. On peut dire que BTC à gagné la guerre médiatique. Malheureusement, il est régi par des développeurs et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il serait revendu à un prix exorbitant. Le but est de spéculer au maximum. Les paiements avec BTC, particulièrement les petits paiements, ou les transactions de toute nature non-monétaires, sont méprisés.
BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées. Un nouveau scindement de BCH est prévu pour novembre 2020 suite à des conflits internes et l'incapacité à avoir un système de gouvernance dans un projet où les règles changent en permanence.
BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par la preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. Il s'agit d'apporter une réelle innovation technologique au monde plutôt que de spéculer. En tant que seul réseau bitcoin totalement sans besoin d'autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucune limite dans son protocole sauf l'esprit humain, l'innovation et l'esprit d'entreprise. Il vise également une adoption mondiale notamment par les pays pauvres afin d'apporter la liberté monétaire et l'inclusion à l'économie mondiale de ceux que les grandes entreprises actuelles comme Visa dédaignent comme pas assez profitables pour leur accorder leur services.
Et c'est la racine de la haine envers BSV.
Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompaient depuis le début sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie de l'histoire médiatique qui a été crée sur Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité, et surtout pas à usage des plus pauvres. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing, de l'objectif d'inclure enfin les plus pauvres dans l'économie mondiale, et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin!
C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin par des attaques personnelles - de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques.
Qui est le Dr Craig Wright et que fait-il?
Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international.
En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code de Bitcoin révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et d'autres forums, et nouvellement financés par l'argent de la startup pro petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer et doit rester réservé aux riches, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Voici un schéma qui retrace les financements de Blockstream et révèle comment le groupe Bilderberg, la banque centrale américaine (FED) et Mastercard on pris le contrôle du réseau BTC via Blockstream afin de le soumettre à leur propre profit: https://imgur.com/eFApDVE
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright en justice pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que son frère Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et il a investi une fortune incalculable dans cette attaque et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi.
Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright malgré sa volonté et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation.
Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiale de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, croyez moi, des gens sont morts».
Les attaques en cours
Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelles. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment:
«Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC)
«Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC)
«Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC)
«Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, et franchement, c'est ce qu'est Gmaxwell.» - Splashtalk 20h00, 22 janvier 2006 (UTC)
«Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC)
Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel contre une version de Bitcoin libéré de ses limites.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre médiatique anti-BSV est Calvin Ayre: un milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur la liste des «plus recherchés» du gouvernement des USA pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation mais a été le fer de lance de la modernisation des lois américaines qui existent aujourd'hui sur les marchés. Il est respecté pour son travail dans l'industrie du jeu, des médias et de la philanthropie. Calvin est le bienvenu aux États-Unis malgré la critique souvent citée selon laquelle il serait une sorte de hors-la-loi.
Calvin Ayre
Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes depuis plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups de l'espace BSV. Bien qu'il soit probablement le plus gros investisseur à ce jour, il n'est pas le monopole que les petits-blocs laisseraient croire. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence.
Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés qui abusent de la censure. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely.
Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants.
Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Planaria Corp de Unwriter.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage (autre nom pour la puissance de calcul du résau). Alors qu'au tout début de BSV, les entreprises appartenant à Ayre représentaient une quantité importante de hachage sur bitcoin, afin d'assurer sa survie, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Ayre tels que Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup se déclarent les ennemis. Ces mineurs soulignent bien la nature ouverte et sans permission de BSV qui permet à quiconque de participer, notamment à ses ennemis!
Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV.
Mais pourquoi Craig poursuit-il des gens en justice ?
Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude sans preuve cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal afin de pouvoir apporter les preuves de ses accusations. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal. Le Dr Wright à depuis abandonné tous ses procès pour diffamation à l'exception de celui contre McCormack qu'il souhaite continuer pour faire exemple.
Cela a aussi engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance-Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages twitter demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas cette version de bitcoin à la suite de ce drame public. Il faut noter qu'après 2 ans, Binance a retourné sa veste et est aujourd'hui devenu un des principaux mineurs de BSV.
Au fur et à mesure que les choses progressaient, le fondateur de bitcoin .com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte auquel le Dr Wright s'était opposé et pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que s'il continuait, des poursuites juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais il à décidé de poursuivre les accusations publiques jusqu'à ce qu'il soit également entendu devant le tribunal pour fournir une preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Aucune preuve n'a jamais été fournit, mais le Dr Wright a depuis abandonné ses poursuites contre Roger Ver pour se concentrer sur son procès avec Kleiman et celui avec McCormack ainsi que son travail sur Bitcoin.
Et maintenant que se passe-t-il ?
Nous avons établi l'histoire du Bitcoin, de sa guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport technique Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public.
Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur l'orateur Gary Vaynerchuk ainsi que d'autres orateurs prévus pour cette conférence, afin de les forcer à annuler leur participation. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un gigantesque cas de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin BSV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale.
Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de protection de niveau mondial. Il est utilisé par des entreprises indépendantes afin d'apporter des innovations technologiques et possède un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux. Les transactions sont instantanées avec des frais de 0.0002€ par transaction en moyenne, explosant tous les records de compétitivité de l'écosystème et permettant aux plus pauvres de la planète d'enfin accéder à l'économie digitale mondiale. Les mensonges sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaies qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie des arnaques de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle.
C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager à créer des entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie qui à un potentiel unique dans l'histoire, et qui les rendrait obsolètes.

Des exemples d'applications Bitcoin que vous pouvez utiliser dès aujourd'hui ?
Les applications qui sont construites sur Bitcoin et interagissent entre elles par ce biais créent ce qu'on appelle le "Metanet". Si vous vous sentez prêt à faire le premier pas dans le futur vous êtes libres de tester les applications les plus populaires du Metanet sur https://metastore.app/apps?sort=money
Le site le plus populaire du Metanet à ce jour est Twetch, une version de twitter incensurable sur la blockchain que vous trouverez ici : bit.ly/twetchapp

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.

Moh (Binance Angel)🇳🇬,
Please join me to welcome, “CHROMIA CEO & Co-founder, Henrik Hjelte” and “ CMO, Serge lubkin”
Oh, before we proceed, kindly introduce yourselves and tell us a bit about your roles at Chromia u/sergelubkin & u/henrik_hjelte.
Henrik Hjelte,
Ok, I’m Henrik, I’m CEO of ChromaWay that crated the Chromia project. My background is a bit mixed: developer for 30+ years (since 80: s), but I studied other things at university (economics, politics, social sciences philosophy). Life is more than computer you know… I worked with FInance/IT then started a web startup and got to know Alex Mizrahi who worked as a developer….
Web startup didn’t fly, but Alex showed me bitcoin. When I finally read the whitepaper I was blown away, and joined Alex colored-coins project, the first open source protocol to issue tokens. in 2013.
So, we started with open-source tokens (that kickstarted the blockchain industry. Then started company together 2014.
That is a long intro, I’ll shut up now… Thanks….
Serge,
I’m Serge, I’m assisting Henrik today and I work with Chromia marketing team as well as on some business development projects
Moh (Binance Angel)🇳🇬, , Question No 1 :
Kindly describe the CHROMIA project and what it aims to achieve?
Henrik Hjelte,
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. There is a blog post about it, I’ll share later. On lines of code.
The aim of Chromia is to combine relational databases, which exist in every kind of organization, together using blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
https://blog.chromia.com/reasons-for-rell-compactness/
Moh (Binance Angel)🇳🇬,Question No 2:
What inspired the CHROMIA Core team to pick interest in CHROMIA project? what breakthrough have you achieved so far? what are the present challenges you’re facing and how are you planning to overcome them?
Henrik Hjelte,
We started with public blockchains, tokens in 2012, the world’s first stable coin with a bank 2015 (LHV). When coding that solution, peer to peer payments of Euro-tokens, we discovered we need performance reasons to store all data in a database. We needed to quickly know the “balance” of a user, and can’t loop through a blockchain. And slowly the idea grew that we can make the database INTO a blockchain, integrate completely with the transaction mechanism of a database. So, we did it as a private blockchain first (Postchain), used it for some projects, then came up with the idea to make a Public Blockchain based on it.
The motivation is that we felt we needed a better programming model for blockchains. Our CTO Alex has always been thinking of optimal solutions for blockchain technology and has lots of experiences thinking about it. Also: make real-world useful things. For example, we support free-to-play models since users do not need to own “our” token to USE apps, the application itself (often the developer) pays for hosting. And of course, great performance. Also: more knowledge of who runs nodes and risk level. So, it is more suitable for enterprises.
In Chromia the application (at the start the developer) decides Who should be allowed to run its own blockchain (every dapp has its own blockchain). You can also say on a higher level that we want to provide technology to create “Public applications”, a tool
that enables us to create a fairer world.
https://blog.chromia.com/towards-publicly-hosted-applications/
Moh (Binance Angel)🇳🇬, Question No 3 :
Why did you create your own blockchain instead of leveraging on existing and proven base layer protocol?
Henrik Hjelte,
None of the existing protocols are suitable to support large-scale, mainstream applications. We designed Chromia to give our users exactly what they want; fast support, useful features, with an affordable service cost. Other platforms do not have the ability to host data applications in a decentralized and secure way, as Chromia can. Chromia also has its own bespoke programming language that sets it apart from SQL-based platforms. It’s so easy to use, even non-developers can understand it!
The other big difference with Chromia concerns payments. Chromia gives its users freedom from having to pay for each transaction. With Chromia, you have the flexibility to decide how to set fees for your dapp
And when it comes to “proven base layer protocols”: they are just a few years at max. Chromia is built on top of Postgresql, that has been used in enterprises for decades, a really proven technology. And the Java virtual machine on top of that. This is proven tech, at core.
Moh (Binance Angel)🇳🇬, Question No 4 :
What is Postchain?
Henrik Hjelte,
Postchain is an open-source product of ChromaWay for enterprise clients and it’s the core technology on which Chromia is built.
Postchain is a replicated blockchain and database that offers highly resilient distributed database management with distributed control.
Postchain is the only product on the market that combines the immutable consensus of a blockchain and the properties of a real database management system (You know, the tech that built SAP, Facebook, Banks…) …
Postchain allows you to share information between companies and/or individuals in a secure and transparent way.
That is the low-level base of Chromia you can say
Moh (Binance Angel)🇳🇬,
Can you please name some of your clients that are using this service already?
Serge,
You mean products built on Postchain? Also, Stockholm Green Digital Finance, Green Assets Wallet that’s now functioning on Chromia Bootstrap Mainnet.
Big financial institutions
It’s only a beginning of course, but very promising one. https://greenassetswallet.org/news/2019/12/12/launch-of-the-green-assets-wallet
Henrik Hjelte,
We got a lot of attention with the Swedish Land registry; we did a joint project between them and banks and a telco etc on postchain as base.
Then, right now we do a large project with the Inter-American Development bank also about land-registration (processes) in South America.
We had a client, Stockholm Green Digital Finance, that did a system for green bonds (tracking environmental impact. Yes, as Sege says, it was later moved to Chromia…
Which is cool. Also, another external development company did that phase of the project, proving that other can build on our tech,4irelabs from Ukraine is their name. Some companies using the GAW: Blackrock. SEB Bank etc…
Also, we have done more projects, in Australia, asia etc. Oh Daimler too (the Mercedes company) …
Moh (Binance Angel)🇳🇬,
Lots of enterprise clients you’ve got. No wonder I do see the meme “CHR=ETH KILLER”
Serge,
It’s a meme from our supporters. But we believe we can coexist:)
For some niche things eth is good :)
So, no killing :D
Henrik Hjelte,
We want to work with partners too for this, we can’t do all projects ourselves. Also, for Chromia projects, ChromaWay company can help do support maintenance etc. So, it is not competing, it adds value to the ecosystem.
Yeah ETH is good too, for some applications. We are friends with them from colored-coin times.
And colored-coins inspired ETH, and ETH inspires us.
Moh (Binance Angel)🇳🇬, Question No 5 :
Lastly, CHROMIA is already doing very well in terms of business. You just got listed on BINANCE JEX, you are on-boarding new clients and dishing out new features. But what’s next? Is there anything to be excited about?
Henrik Hjelte,
Plans for 2020 are to both release a series of dapps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release the mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework called Chromunity, now released to TestNet. It is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
https://testnet.chromunity.com/
Games coming are:
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff. Already on TestNet and you can take a peek on it at https://www.minesofdalarnia.com
more coming…
Krystopia 2, novas journey. A puzzle game done by Antler Interactive. Could only find trailer though: https://www.youtube.com/watch?v=-G95-Dw3kI4
However, we have even larger ambitions with blockchain gaming…
We are doing A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
Another exciting relase is an indie game Chain of Alliance, done by two external developers. It is a strategy game with full-logic on blockchain. Public release on TestNet on May 22!
More coming in 2020: Other dapps from other companies, one in impact-tech.
That is a serious app, Chromia also works outside gaming and social media for enterprises and startups
And I hope some of you will do something, we want to support dapps on the platform so reach out to us…
Moh (Binance Angel)🇳🇬,
When can we be expecting the mainnet? Any approximate time? I’m sure the community will really excited to have that info
Serge,
It’s now in Bootstap phase, so it’s technically already functioning. MVP will be very soon
Stay tuned;)
Twitter questions Vs answers
Ellkayy,
What’s the unique thing in Chromia that no other blockchain has, that makes you the better option?
Henrik Hjelte,
Unique: Chromia is the only blockchain that also has a real, proper database built-in. And blockchain is about managing data in a shared context. How to best managed data was solved in computer science already. So far, it is the relational algebra model that is used in 100% of all enterprises, and has an 85% market share. Chromia is the only blockchain that use that model and that power.
Ellkayy,
Why Chromia use RELL and not SQL or JavaScript? Can developers with other language knowledge use Chromia?
Serge,
Rell is the only language on the blockchain side. You can combine with anything on client-side, although now client only exists for JS/TS, C# and Java/Kotlin. Rell is a language for relational blockchain programming. It combines the following features:
1 Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
2 Normal programming constructs: variables, loops, functions, collections, etc.
3 Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Roshan DV,
I have been monitoring your project for a while but some concerns about it: Your project will build your own core network, so you have more visibility than Ethereum and NEO. These are projects that were born before and which also have a very large community. And what can assure you that your project will guarantee the functionalities that you have defined?
Henrik Hjelte,
What came first? I want to remind that Vitalik was in the colored-coins project, led by our CTO and we had blockchain in production before ETH and NEO etc existed. We are the old dogs…
Large community: We are part of the same community. When developers are fustrated and want to try new tech, they go to us from other blockchains.
Also, we have a large potential: SQL (close to Rell and our tech) is the world top 3 language. Bigger than Java. Bigger than PHP. Only beaten bny HTML and javascript. Soliditiy is not on top 20 list. THere are millions of developers that know SQL. That is potential for community… (source is Stackoverflow annual programming survey).
Paul (Via Manage),
What are the utilities of Chromia and what purpose does the Chromia coin serve?
Serge,
Chromia meta-token called Chroma (CHR). It is used in Chromia to compensate block-producing nodes by fees. In Chromia, fees are paid by dapps, which can in their turn collect fees from users. Chromia provides mechanisms which balance the interests of developers and users. Dapp tokens can be automatically backed with Chroma, providing liquidity and value which is independent of investment into the dapp. Dapp investors can be compensated in Chroma through a profit-sharing contract. For developers, Chromia offers the opportunity to derive income from dapps. This incentivises the creation and maintenance of high quality dapps because better dapps generate more income and create more demand for tokens owned by the developer. The Chromia model is designed to support sustainable circular economies and foster a mutually beneficial relationship between developers, users, and investors.
Idemudia Isaac,
Thank you very much u/henrik_hjelte u/sergelubkin
You stated your plans for 2020 is to release series of dApps. What kind of large scale, mainstream decentralized application and $Chromia products do you think is suitable for the Nigerian environment?
Henrik Hjelte,
Actually, this is why we want to work with partners. We cannot know everything, For African market we have seen of course payments/remittances (but it has fallen out of trend). We would love to do real-estate /land-registration but we understand we need a strong local partner (more than a single person, a real company or organization driving).
●CC● | Elrond 🇵🇭,
What plans do you have to building a vibrant global community around Rell? And how would you go about encouraging/incentivising such ‘Rellists’ around the world to build dApps on Chromia? u/henrik_hjelte u/sergelubkin
Henrik Hjelte,
For developers (I am one too, or used to be) you normally need to prove a few things:
\ That the tech is productive (can I do apps faster?)*
\ That it is better (less bugs, more maintainable?)*
Then the community will come. We see that all the time. Look at web development. React.js came, and developers flooded to it. Not because of marketing on Superbowl, but because it was BETTER. Fewer bugs and easier to do complex webapps.
So, at core: people will come when we showcase the productivity gains, and that is what we need to focus on.
●CC● | Elrond 🇵🇭,
Why do you choose to build Chromia token on ERC20 instead of other blockchain such as BEP2, TRC20…or your own chain while ERC20 platform is very slow and have a case of fee? u/henrik_hjelte u/sergelubkin
Serge,
So far Ethereum has the best infrastructure, it’s the oldest and most reliable network for tokens. It also became the industry standard which exchanges utilize. We will transfer 80% of all erc20 tokens to our Chromia blockchain when it’s ready for that.
Koh,
In your whitepaper it says in the upcoming version of ChromiaWallet that it will be able to function as a Dapp browser for public use. Q) Will it be similar to the Dapp browser on Trust Wallet?
Serge,
It’s live already try it http://vault-testnet.chromia.com/
It’s the wallet and a dapp browser
CHROMIA is SOLID,
Your metamorphosis is a laudable one,surviving different FUD, how have you been able to survive this longest bear market and continue building and developing cos many projects have died out in this time period!
Henrik Hjelte,
You need to know we started a company before ETH existed. There was 0 money in blockchain when we started. I did it becuase it was fun, exciting tech and MAYBE someone would be interested in the thing we made “Tokens”…
We were never in the crazy bull-market, manly observed the crazies from the side. We fundraised for CHR in a dip (they called it bear market). ChromaWay the company also make money from enterprises.
Алекс,
What is SSO?
What makes it important for chromias ecosystem?
Why should we users be attracted to it?’
Serge,
Chromia SSO is perhaps the most important UX improvement that Chromia offers the decentralized world. It revolutionizes the way users interact with dapps. Any dapp requires users to sign transactions, that means they need a private key. Control of the private key is control of any and all dapps or assets associated with it. This means that private keys have an especially stringent set of security requirements in a blockchain context — they control real value, and there is no recourse if they are compromised or lost. https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
Olufemi Joel,
How do you see the Chromia project developing in 3 to 5 years, both on the commercial level and on the evolution of the company? What are the plans for expansion in different regions? Are you going to outsource the team/skills or keep it centralized and set up offices?
Henrik Hjelte,
I take part of the question. On outsource: we were a distributed team from day one, with co-founders from 3 countries (still living there). We are distributed now, Ukraine, Sweden, Vietnam, Croatia, China are “hubs” then we have individuals too. No big plan, just where we found great developers…
Park Lee, u/henrik_hjelte
You claim CHOROMIA have fast support, useful features with an affordable service cost. That fast and the fees are cheap but can you guarantee stability?
What’s the Algorithms which are used by CHROMIA for that fast? And Can you explain it?
Serge,
We use PBFT protocol with some features of DPOS, this plus sidechains parallelism offers almost unlimited speed and scalability. We also use the feature called anchoring to secure all transactions in batches on Bitcoin blockchain.
Mario Boy,
What are you guys trying to achieve as an end goal? The next Ethereum? Or the next enterprise version of Ethereum? Or something different?
Henrik Hjelte,
The end goal… good question. When we started in 2014 there were no other blockchain companies, so we wanted to do the best blockchain technology in order to enable a decentralized world with more fair applications. And that is what we still do. Technology/software that can enable people to make a fairer world
Erven James Sato,
“STAKING” is one of the STRATEGIES to ATTRACT USERS and ACHIEVE MASS ADOPTION
Does your GREAT PROJECT have plan about Staking?
Serge,
Yes, we announced our staking plans couple of months ago https://blog.chromia.com/on-providers-and-stakes/
We are working with our current partners to make it accessible for general public.
Chizoba,
I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte,
ChromaWay the company started Chromia from code done as postchain. This is normal in open-source development, a company that leads development. But Chromia will be a decentalized network, so ChromaWay will not make direct money out of it more than if we have a role as a Provider (and get payed for hosting). ChromaWay can indirectly make money from optional support and maintenance etc. Also, this, perfectly normal in open-source world.
And it also benefits Chromia that there is a market for support.
A market open for competition.
No special treatment for “ChromaWay”
Enajite,
How to start coding on Chromia?
Henrik Hjelte,
Go to https://rell.chromia.com and follow the tutorial. Enjoy the free time you get compared to other blockchain languages…
●CC● | Elrond 🇵🇭,
Chromia process 500 TPS, these is slow compare to other Blockchains, where we can see now 60K TPS if more capacity require, how can that be? u/henrik_hjelte u/sergelubkin
Serge,
Yes, if you need faster speed you can use parallelism by having multiple blockchains for your dapp. Also, by optimization and better architecture sky is the limit.
Delphino.eth ⟠,
Can we consider Chromia an hybrid? For its mixing of Blockchain and a Database?
Henrik Hjelte,
Yes and no. I want to stress that Chromia is a FULL blockchain. It is not only “inspired”. It is a blockchain AND a database.
I tend to think about Hybrid more in the usecases that you might have as a customer. For example, a bank might want to have some data/transactions private (as a private blockchain) and have another half of the application with public data (on Chromia). So that is a hybrid solution, and Chromia ROCKS in that segment since it is the only blockchain that is complete relational database (what the normal world uses anyway for 85% of all applications)
Example area: “open banking”
Steve bush,
How will Chromia I have any empower Investors, Companies, Developers, Platform Users to
deliver impactful solutions and bring value to people all over the world?
Henrik Hjelte,
In order to make blockchain go big, we need to have users. Users need to be able to use apps with ease. Chromia have features like single-sign on (ease of use), but importantly do not require owning tokens to USE apps.
Also, it needs to be easy to make applications. For example, if you are a student in US and came up with an idea, you want to make an application for your school. Let’s call it “thefacebook”. You code something in PHP and MySQL. DID YOU SEE THAT. SQL. SQL.SQL. It is the same tech that Chromia has but no one else in the blockchain business. SQL rules the world if you look outside the crypto bubble. Google the Oracle head-office… 100% of all enterprises use it… Because it is easy and powerful.
And we even improve on SQL with Rell….
So, compare that with a hacky virtual machine that have a few years…. 😊
August,
“Mines of Dalarnia” is a game that has caught my attention a lot, due to its simplicity and quality. But in the time that I have used it I have not been able to differentiate between the Chromia blockchain of this game and that of the competition? What other games do you have next to develop? I would like to give ideas in those games like a Gamers!
Henrik Hjelte,
We thought about in corona time sports club might want to engage more with their fans digitally. And of course, E-Sports is getting a real momentum as the young generation grows up. Now a bit sad that all games are centralized. My daughter will be sad when (at some day?) they will close down roblox… it happens to all centralized apps eventually… that is what we fix. Power to the Public to control apps and their future. I’ll repost again Alex post. Sorry I like it a lot… https://blog.chromia.com/towards-publicly-hosted-applications/
Bisolar,
Good day Chromia team from a Chromia fan
Can you tell us Chromia’s geographical focus at the moment and the proces it follows for it BUSINESS DEVELOPMENT?
What factors do you consider before identifying NEW MARKETS to enter?
Serge,
Chromia will initially focus on community building in China, Korea, US and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.
Current community growth strategies of Chromia include:
Chromia blockchain incubator creation to welcome more projects to the Chromia blockchain
Host blockchain gaming conferences, workshops, and meetups to engage with potential users.
Provide online and face-to-face tutorials to engage with dapps developers.
Attract blockchain developers through direct and indirect approach via specialized platforms and communities.
Develop our relations with existing and previous corporate clients, and their partnership networks to participate in their blockchain ventures
Launch Node program to encourage system providers to run nodes on the Chromia blockchain.
Staking program for Chroma (CHR) tokens
Active community engagement via social channels.
Future community growth strategies of Chromia after Mainnet launch include:
Partner with more gaming studios, startups and enterprises
Build local communities with Ambassador Programs.
Partner with external incubator and accelerators to provide blockchain expertise and introduce projects to Chromia ecosystem
Continue organizing hackathons around the world to attract more developers.
Emmanuel,
I want to know the current structure of your roadmap? What is the future roadmap of CHROMIA? Is there any key milestone coming???
Henrik Hjelte,
It is easy to do a roadmap; anyone can make a pape plan. But I think they are used in the wrong way. Software is hard, blockchain is even harder because it NEEDS TO BE SECURE. No MVP releases. We cannot even have roadmap deadlines and skimp on quality. Where we are now though is: Rell language finished so much that developers can write apps and see its magic. We have external devs doing dapps. We have the first phase of mainnet. We have a series of releases coming up. We will release mainnet when it is secure enough, and gradual roll out. I think quite soon, development is going great at the moment, a bit quicker than we though.
Ellkayy,
Why doesn’t Chromia transactions use gas? How do you power transactions then?
Serge,
Main feature of gas in Ethereum is to pay for transactions for miners get rewards. In our scenario Providers get rewards from dapp owners. So dapp owner pays for storing their dapp. It’s like Amazon Web Service model. Then dapp owner can monetize it in its own way.
Ellkayy,
Many developers don’t know RELL, just Solidity and SQL. Is this a barrier or threat to Chromia? Why RELL is better?
Henrik Hjelte,
Very few developers know Solidity. Do a search on github. I referred previously to stackoverflow programming language survey results. https://insights.stackoverflow.com/survey/2019#technology
If you know SQL, you learn Rell in a day.
SQL is the top 3 language here. I’d say there are millions that can easily jump to Rell.
Soldity or other blockchains, not on top 20 list even.
Rell is a hipper, nicer version of SQL that is also a “normal” programming language.
Developers like to learn new things, new languages. Otherwise we would be stuck with PHP, the DOMINANT language. Well, is it still? Seems javascript and react.js and node etc is taking over…

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

https://preview.redd.it/s2gmpmeze3151.png?width=256&format=png&auto=webp&s=9759910dd3c4a15b83f55b827d1899fb2fdd3de1

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.

One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

Nano #Ama on Binance Spanish telegram group!!

Regards!! I'm Jesús Zambrano, member of the Hispanic community of NANO for a long time. Last thursday, we had an interesting and enjoying Ask-me-anything at Binance Spanish community on telegram with the people behind NANO, Colin LeMahieu (Founder and Executive Director) and Zach Hyatt (Proyect Manager), where we take advantage of their kindness and willingness to ask them some questions and share opinions about de currency. I will share a compilation of some of the questions and answers.
-(Admin) ¡Welcome Binancians to our following AMA!
I will explain how AMA works; we will have three (3) segments.
Segment #1: I am going to ask to our guests five (5) questions and then they will answer them.
I will be explaining the rest of the segments as we conclude one of them.
-(Admin) Today we have the great pleasure of having Colin (Founder and Executive Director) and Zach (Project Manager) with us in our chat room. Could you give us a little introduction about you?
- (Zach) Hi everyone, I am Zach Hyatt, the Project Manager at the Nano Foundation and am excited to help answer questions about Nano. I live in Austin, TX where it is quite hot right now!
-(Colin) I’m Colin LeMahieu, founder of Nano. I’m a computer engineer and I’ve worked at companies like Qualcomm, Dell, and AMD. I have been working on Nano for about 5 years now and I’m really excited to talk with people who are interested as well!
-(Admin) It is a pleasure for us to have you here, I have to say that on a personal level, I have been a follower of the project for a long time now, so it is incredible for me to be able to count on you tonight, we will start with segment # 1, with the questions I have for you.
Feeless transactions and in record time! What is NANO? Can you give us an introduction to the project?
-(Colin) Nano’s goal is to solve problems with other cryptocurrencies and make sending value fast and fee-less. It has a unique design to allow us to accomplish this. We want people to have the option of using decentralized digital money instead of fiat money anywhere in the world. Nano is accessible and easy-to-use today and we plan on keeping it focused on these goals.
-(Admin) Thank you for answering my first question, I am delighted with the features offered by the project, every week they are updating and making important changes that help to improve the ecosystem that surrounds the team.
Here you can find all the weekly updates: https://nano.org/en
Previously the project was called RaiBlocks, it appeared for the first time in an ad in Bitcoin Talk in 2015. Can you tell us why a name change came up later?
-(Zach) Yeah, absolutely. Although the original RaiBlocks name has a special place in our history, it was difficult to pronounce in some areas of the world and caused confusion with certain users. We decided to move to a shorter name that not only was easy to pronounce but also reflected the fast, efficient nature of the protocol.
-(Admin) A short and quick name to pronounce, definitely NANO is perfect to define it!
My third question is the following; I had seen a very interesting gif early in the chat and it is just about the question that I came to ask.
Currently, NANO has 100% of its tokens in circulation and these tokens were distributed through Faucets, so it meant that any user with a computer could get coins simply by completing some captchas, can you tell me which has been the experience of users when using this method?
-(Colin) The faucet was a great way for us to distribute coins to people who have never used it before. Cryptocurrencies that use mining end up distributing only to people who have money to buy the mining hardware and this is unfair. We had a lot of people from Indonesia and Asia in the beginning of our distribution and at the end there were a lot of people from South America, Venezuela and Brasil that were getting most of the Nano from the faucet. We think this was a fairer way to do it and it got Nano into the hands of people in different locations, and it had a very positive impact on their lives.
-(Admin) This is incredible! thanks for your answer!
Can you tell us about what the Open Representative Vote is about and how it protects the network?
-(Zach) Nano uses voting to get confirmation on the network instead of mining and the nodes on the network that create votes are called Representatives. Open Representative Voting allows people who have a Nano balance to pick whatever representative they want to vote on their behalf. This allows the people who hold Nano to decide who generates consensus instead of mining companies. The voting process is very efficient and is a big part of what allows Nano to be fee-less and use very little energy.
-(Admin) Very good! The last question on my part:
Nano PoW is your new approach, I have read a pretty interesting example with emails, can you explain what it is about?
-(Colin) Nano PoW is a research project we’re doing in order to create a proof of work algorithm that uses less energy than other popular algorithms. Since Nano is fee-less, there must be a method to limit transactions going onto the network, which this PoW achieves. With the goal of using more memory in the process instead of CPU cycles in order to generate proofs, this new Nano PoW will help prevent ASICs from being able to cheaply send lots of transactions. It’s important for a cryptocurrency that’s used around the world to be energy efficient and green so continuing our research on this is important to us.
-(Admin) https://medium.com/nanocurrency/nano-pow-the-details-ba22a9092d6f
Thanks for your answers, Colin and Zach! I have a video, taken from your YouTube account that I would like to share with the community
https://www.youtube.com/watch?v=eh9pA8UCUrI
Can you tell me what we see in this video?
-(Colin) This is a video of how fast our transactions send and receive. You can see it takes less than 1 second to finish which means you can use it as a currency.
- (Zach) The wallet was made by developers in our amazing community, it is called Natrium. It really shows how fast Nano is and how it is easy-to-use!
-(Colin) You can also see how simple it is to use. You just scan, enter an amount, and send. There are no complicated setting which is great for new users and great for adoption.
- (Zach) And the best part is, there were no fees at all for that transaction. In fact there have never been any transaction fees on the Nano network ever!
-(Admin) Great! That's why I wanted to share it with everyone, yesterday I could try the wallet and it is really spectacular to use, thank you very much for that excellent explanation, please stay with us, now comes the part in which our users participate
Segment 3, community questions
Q -First congratulations on your project, it is amazing. Now, does nano BlockChain have another use besides making transactions?
A - (Zach) Thank you! Nano has always been focused on transfer of value and will continue to maintain that focus. The overall design is aimed at doing only this so it can remain fast, efficient and fee-less.
Q -Good evening! I understand that thanks to its architecture called "Block-lattice", each individual provides the computing power necessary to verify their own transaction, thanks to this they do not use miners to confirm transactions and they do not apply commissions of any kind. My question is: How did this occur and how difficult was it?
A - (Colin) It’s simila, transactions are validated by votes from the representatives, not by the PoW. The PoW is a way to slow down how fast people can create transactions so they can’t spam the network.
Q - Do you have any short or long term projects so that transactions using $NANO were anonymous?
A - (Colin) Long term we want to see what privacy options exist and are fast. Most privacy schemes make the transactions very big or slow to process and it’s important for things to remain quick and efficient so we can have fast transactions.
Q - We are living in Venezuela many changes in the cryptocurrency sector, the integration of crypto for service payment and product purchases is already a reality. What agreements has NANO made with service stores to integrate it as a means of payment? I want to pay my movie ticket with NANOS
A - (Zach) Thanks for your interest in Nano. We are always looking for ways to allow everyone to use Nano in as many places as possible. Although separate from our organization, we are aware of the efforts of the Nano Venezuela organization and try to support them when possible in bringing Nano to as many people and stores in Venezuela as possible.
Q - (7 questions made from one persone at once)
  1. How do you manage to make your transactions virtually instantaneous?
  2. How do they create part of the company's livelihood if no fees are charged for transactions?
  3. Why does $ NANO consume so little electricity?
  4. Requirements for a medium-sized company to adopt nano correctly as a means of payment?
  5. Since 100% of the $ NANOS are distributed, I have seen something in Medium that talked about `` Nano PoW '', could you tell me a little more about how it works? What profit will the person / institution get that puts hardware for their PoW? Will more $ NANO be created apart from those already in circulation?
  6. What do the representatives earn for putting their vote and validating blocks if 100% of the $ NANOS are already created / issued?
7- Since your policy / slogan / commandment is to be a cryptocurrency without fees, shouldn't you force exchanges in which $ NANO is present that they don't charge withdrawal fees?
A - (Colin)
  1. Transactions are fast because they’re validated by voting. The votes get transmitted around the world in milliseconds and all people have to do is count votes to confirm the transaction.
  2. We use the Dev fund to pay for developing the Nano protocol. The Nano protocol is a free tool that other people can build businesses on. We have ideas for businesses that can use fast, free money in order to help people send money to their family in other countries or pay microtransactions. It’s similar to Linux, it’s free but big companies use it because it saves them money.
  3. Nano uses little electricity because we use voting for validating transactions. Voting is just sending data over the internet which is power efficient.
  4. You can run a nano node with 40-60$/mo using cloud virtual machines
  5. Nano pow is just a more efficient way to slow people down from sending transactions to the network
  6. The most important thing is: why does a company want to use cryptocurrency? They want to use it because it saves them money on bank fees, etc. Since 40-60$/mo running a node is less expensive than their bank fees, they want to participate in the network to keep it going and save them money.
Q - Knowing all this about Nano, could you say that Nano is one of the most energy-efficient, Ecological friendly currencies in existence?
A -(Zach) Absolutely. We care about making a positive change in the world and so pride ourselves on leaving as little energy trace possible in the world. It may just be the fastest, most efficient transfer of value available.
Q - If the nano protocol had not passed the Red4Sec signature security test, would it have any vulnerability today?
A - (Colin) The Red4Sec audit didn’t find any critiral vulnerabilities in Nano. In fact they did the audit twice because they couldn’t find anything wrong and that never happened before.
It’s important for us to keep the code high quality and we will do audits again in the future because it’s important to make sure everything is secure.
Q - I'd like to see more development of Nano by using SMS on our phones to avoid the problem of no Internet connection at the moment
A -(Zach) As much as we like the idea of SMS, unfortunately it is not a secure network so managing Nano transactions over it brings some unique requirements. However we are always innovating and trying to make Nano as easy and accessible as possible so hope advances can help over time make it more accessible in this area.
Q - What plans do you have to close this 2019 to increase adoption in Latin America?
A -(Colin) We are very excited about the passion we see in the south american community. We would love to make it down to VE however in the mean time follow nanoVE for updates and meetups - there may be one near you soon!
Q - How will you make the adoption and use of $ NANO continue to increase especially in markets where other cryptocurrencies are gaining more ground?
A - (Colin) Our focus is to build tools people need to accept cryptocurrency. Right now it’s still difficulty and expensive. One thing we’re making is the device Appia which can accept cryptocurrency similar to a credit card. We made this device very inexpensive and can connect over wireless so it can be used in markets or resturaunts or other places cryptocurrency is not yet available.
- (Admin) Thank you very much for your answers! You are the first guests that answer all the questions of our users, you are amazing guys!
@AndyNano It was amazing to meet you, I learned a lot from you
@FundacionNanoVE Thanks for making this happen! excellent work
@nano_isam Thanks for everything buddy!
-(Zach) Can we ask a question to the channel?
What are the top things Nano can do to help you in your daily lives?
-(Colin) My question: How do you store cryptocurrency safely? Where do you back up your seed so it isn’t lost or stolen?
A - In Venezuela we currently have a problem with conventional payment processors, they are very slow, it would be great to be able to see people using NANO to make their purchases at any store in Venezuela, 0 commissions and instant transactions, is what we need
A - Fast transactions are what can help society the most, and except that, the best thing is that it is very cheap ... from there it is addition, those are the main characteristics that we look for the most
A - encrypted file in a pendrive
A - Nano is a direct competition to the vast majority of Cryptos, in transaction speed and that it is literally free to send or receive, nothing to wait for 5 hours or the next day when you pay for items or services with Crypto, let's increase the adoption of nano!
-(Colin) Question: Are there barriers to using Nano in your country right now?
A - No barriers in Venezuela
A - No barrier what is lacking is greater diffusion in means to give greater projection and that the adoption arrives. Here I am to support NANO!
A - There should be no barriers to the payments we wish to make, freedom above all
-(Colin) Fantastic!
- (Zach) Thanks everyone, I have to go but I appreciate all the awesome questions and answers!

Innovative ITO mode ITO Platform Currency Distribution Method
ITO (Initial Trust Offering) includes three important aspects: fundraising, Token distribution, and fund return. The ITO model is open and transparent and 80% of the funds raised will be returned to the user and can be verified. This model allows the project side and the user to reach a consensus, which is a good solution to the problem of mutual trust.
1. ITO — Introduction
The core Bitcoin concept is based on the building of consensus between a project party and the decentralized investor community. The transaction status and the amount of money held are necessarily open and transparent. Bitcoin earnings are owned simultaneously by long-term holders and the community. Thus, the success or failure of a project depends on their ability to reach consensus. Failure to do so can result from a wrong choice of ICO versus IEO tokens. Or it might be a lack of transparency by the project side in its use of funds raised. This can lead to loss of community trust and ultimately confrontation.
The Bitroom team believes in Bitcoin. In order to reach a consensus between a project and the community, Bitroom has innovatively createdå the Model of Initial Trust Offering (ITO).
Under the ITO model, the project party publicly and transparently raises funds from the community on the blockchain. The project party then announces a fundraising address and a Token distribution address, with all funds raised sent to that address.
Token distributions are all transferred through the same distribution address, Fundraising is carried out on the blockchain, Each transaction and the number of positions at each address can be publicly queried. After fundraising is completed, the project party will return 80% of the money to the community as income. This operation is likewise visible on the blockchain. Each return is visible on the blockchain, as is each return operation. The remaining 20% ​​of the funds raised will be used to support the project to move forward.
It can be seen that each step of the ITO model is open and transparent and that each move by the project party and the community, both, is well documented in the blockchain, thus enhancing mutual trust. After the platform closes, the project side will return 80% of funds raised to the community, with the remaining 20% to be used by the project side for promoting project development. ITO is a great innovation, with real capacity to bring about consensus between the project side and the community.
Bitroom's platform currency will be distributed in the form of ITO.

Craig Wright: The Real Satoshi Or The Real Scammer

Today we will focus on Craig Wright, the person who took the liberty to declare himself as true Satoshi Nakamoto and who tries to take all the credit of the creator of Bitcoin, the main cryptocurrency.
Bitcoin is considered to be one of the progressive forms of payments — absolutely transparent, distributed and resistant to external influence. Its creator must be at least a genius, and most importantly, a billionaire — because a significant amount of Bitcoins mined in the early stages of the project is concentrated in his hands. It is known that Satoshi Nakamoto retired from the project around 2010 and no one knows exactly who is he really is.
In December 2015, two American publications — Gizmodo and Wired — published huge investigations aimed at finding a man who has been hiding under the name of Satoshi Nakamoto since 2008. Clues led journalists to Craig Wright, a 45-year-old entrepreneur from Australia, which on many grounds could be reckoned as a true Satoshi. For example, there were publications about the ideas of a decentralized payment system similar to Bitcoin in Wright’s blog in 2008, a year before Satoshi Nakamoto himself created BTC. Another interesting fact is that in 2013 he invested more than one million BTC in the project to create his Bitcoin Bank — supposedly only the creator of Bitcoin could own such amount of coins.
In correspondence with the publications, Craig indirectly confirmed that he is Nakamoto. At the same time, in December, 2015, Wright said that he was not going to talk about himself publicly. But almost six months later Craig Wright appeared on the front pages. Unexpectedly for many, Craig decides to give an interview to the BBC and The Economist, in which once again, but already publicly assures that he is Satoshi Nakamoto. As the main proof, Wright provided a “cryptographic signature” from the private key used in the first Bitcoin transactions by Satoshi Nakamoto himself.
Since then, Dr. Wright did not give up his words and continued to tell everyone that he is Satoshi. Later Craig said that he would sue anyone who slanders him and generally denies his merits in the creation of Bitcoin.
And while he was just talking around declaring himself as the creator of BTC — all this was tolerated and ignored. But when Wright began to threaten all who disagreed with his lies, the crypto-community decided to teach him a lesson.
Binance CEO Changpeng Zhao wrote the following on his Twitter:
“Craig Wright is not Satoshi. Anymore of this sh!t, we delist!”
His example was followed by some other exchanges, like ShapeShift and Kraken, which also announced the delisting of BSV.
Blogger and ex-hacker Nik Cubrilovic and cybersecurity researcher Dan Kaminsky published their own investigations in which Wright is exposed as a great deceiver. Enthusiasts also investigated the activities of Wright and his companies. It turned out that the purpose of the existence of many of them was to draw tax refunds and the operation of other benefits that are provided to companies focused on research activities.
When an entrepreneur’s business started to decline and companies have earned an unpleasant reputation, Wright decides to appear before the public as Satoshi Nakamoto. According to Cubrilovic’s opinion, this could improve Craig’s affairs, attract new investments and add excitement since it is known that Nakamoto owns large amounts of Bitcoins.
Craig’s opponents also notice one detail: Satoshi Nakamoto would certainly stand on the side of the Bitcoin community that would like to leave the BTC system in its original form. However, in a conversation with The Economist Wright drew a different picture: if Bitcoin power can be repeatedly scaled, then it will be able to replace not only all banking systems but many others, becoming a truly mainstream currency.
In this case, the regulation and support of such cryptocurrency would have to be taken up by large organizations — from banks, already interested in using blockchain technology, to entire states. If this happens, Bitcoin will really replace conventional currency but will lose its independence — the main reason for its creation.
Here are some interesting facts about Craig Wright:
  1. In the early 1990s, worked as a sauce cook at a French restaurant.
  2. Wright filed about 114 Blockchain-related patents since 2017
  3. Craig Wright has his own companies, for example, the Tulip Trading company, which has been very successful in developing supercomputers, as well as DeMorgan Ltd and Panopticrypt Pty Ltd, engaged in various operations with cryptocurrencies. But Wright’s main project is, of course, his own Bitcoin SV (Satoshi Vision), which appeared as a result of the fork of Bitcoin Cash in November 2018. The fork’s reason was the dissatisfaction of developers and miners with a size of the blockchain that was originally written in code. Transactions were processed very slowly, so Bitcoin Cash ABC appeared, where the size was increased to 8 megabytes. But this was not enough for Craig Wright, and he initiated the second fork, setting the block size to 128 megabytes in the currency he was in charge of.
  4. In February 2018 Wright was sued by David Kleiman — a computer scientist and cyber-security expert suspected to be one of the developers behind the Bitcoin and the blockchain tech. Kleiman said that Wright stole between 550,000 and 1,100,000 BTC.
  5. In 2018, Craig Wright was sued, accusing him of forging contracts and signatures in order to assign Bitcoins in the amount of $5 billion.
  6. In October 2017, Cointelegraph published a list of the most influential individuals from the blockchain industry. Not finding his name in it, Craig Wright appealed to the media with a comment about their negative mood regarding his personality. At the same time in the Cointelegraph ranking was the name Satoshi Nakamoto. This situation was noted as Wright’s recognition that he is not the creator of Bitcoin.
  7. Craig is suspected of repeatedly conducting operations to cash large amounts of BTC. During one of the checks, he brought the family from his native Sydney and moved to London to continue working and creating his own business.

NANO #AMA ON BINANCE SPANISH TELEGRAM GROUP!!

Regards!! I'm Jesús Zambrano, member of the Hispanic community of NANO for a long time. Last thursday, we had an interesting and enjoying Ask-me-anything at Binance Spanish community on telegram with the people behind NANO, Colin LeMahieu (Founder and Executive Director) and Zach Hyatt (Proyect Manager), where we take advantage of their kindness and willingness to ask them some questions and share opinions about de currency. I will share a compilation of some of the questions and answers.
-(Admin) ¡Welcome Binancians to our following AMA!
I will explain how AMA works; we will have three (3) segments.
Segment #1: I am going to ask to our guests five (5) questions and then they will answer them.
I will be explaining the rest of the segments as we conclude one of them.
-(Admin) Today we have the great pleasure of having Colin (Founder and Executive Director) and Zach (Project Manager) with us in our chat room. Could you give us a little introduction about you?
- (Zach) Hi everyone, I am Zach Hyatt, the Project Manager at the Nano Foundation and am excited to help answer questions about Nano. I live in Austin, TX where it is quite hot right now!
-(Colin) I’m Colin LeMahieu, founder of Nano. I’m a computer engineer and I’ve worked at companies like Qualcomm, Dell, and AMD. I have been working on Nano for about 5 years now and I’m really excited to talk with people who are interested as well!
-(Admin) It is a pleasure for us to have you here, I have to say that on a personal level, I have been a follower of the project for a long time now, so it is incredible for me to be able to count on you tonight, we will start with segment # 1, with the questions I have for you.
Feeless transactions and in record time! What is NANO? Can you give us an introduction to the project?
-(Colin) Nano’s goal is to solve problems with other cryptocurrencies and make sending value fast and fee-less. It has a unique design to allow us to accomplish this. We want people to have the option of using decentralized digital money instead of fiat money anywhere in the world. Nano is accessible and easy-to-use today and we plan on keeping it focused on these goals.
-(Admin) Thank you for answering my first question, I am delighted with the features offered by the project, every week they are updating and making important changes that help to improve the ecosystem that surrounds the team.
Here you can find all the weekly updates: https://nano.org/en
Previously the project was called RaiBlocks, it appeared for the first time in an ad in Bitcoin Talk in 2015. Can you tell us why a name change came up later?
-(Zach) Yeah, absolutely. Although the original RaiBlocks name has a special place in our history, it was difficult to pronounce in some areas of the world and caused confusion with certain users. We decided to move to a shorter name that not only was easy to pronounce but also reflected the fast, efficient nature of the protocol.
-(Admin) A short and quick name to pronounce, definitely NANO is perfect to define it!
My third question is the following; I had seen a very interesting gif early in the chat and it is just about the question that I came to ask.
Currently, NANO has 100% of its tokens in circulation and these tokens were distributed through Faucets, so it meant that any user with a computer could get coins simply by completing some captchas, can you tell me which has been the experience of users when using this method?
-(Colin) The faucet was a great way for us to distribute coins to people who have never used it before. Cryptocurrencies that use mining end up distributing only to people who have money to buy the mining hardware and this is unfair. We had a lot of people from Indonesia and Asia in the beginning of our distribution and at the end there were a lot of people from South America, Venezuela and Brasil that were getting most of the Nano from the faucet. We think this was a fairer way to do it and it got Nano into the hands of people in different locations, and it had a very positive impact on their lives.
-(Admin) This is incredible! thanks for your answer!
Can you tell us about what the Open Representative Vote is about and how it protects the network?
-(Zach) Nano uses voting to get confirmation on the network instead of mining and the nodes on the network that create votes are called Representatives. Open Representative Voting allows people who have a Nano balance to pick whatever representative they want to vote on their behalf. This allows the people who hold Nano to decide who generates consensus instead of mining companies. The voting process is very efficient and is a big part of what allows Nano to be fee-less and use very little energy.
-(Admin) Very good! The last question on my part:
Nano PoW is your new approach, I have read a pretty interesting example with emails, can you explain what it is about?
-(Colin) Nano PoW is a research project we’re doing in order to create a proof of work algorithm that uses less energy than other popular algorithms. Since Nano is fee-less, there must be a method to limit transactions going onto the network, which this PoW achieves. With the goal of using more memory in the process instead of CPU cycles in order to generate proofs, this new Nano PoW will help prevent ASICs from being able to cheaply send lots of transactions. It’s important for a cryptocurrency that’s used around the world to be energy efficient and green so continuing our research on this is important to us.
-(Admin) https://medium.com/nanocurrency/nano-pow-the-details-ba22a9092d6f
Thanks for your answers, Colin and Zach! I have a video, taken from your YouTube account that I would like to share with the community
https://www.youtube.com/watch?v=eh9pA8UCUrI
Can you tell me what we see in this video?
-(Colin) This is a video of how fast our transactions send and receive. You can see it takes less than 1 second to finish which means you can use it as a currency.
- (Zach) The wallet was made by developers in our amazing community, it is called Natrium. It really shows how fast Nano is and how it is easy-to-use!
-(Colin) You can also see how simple it is to use. You just scan, enter an amount, and send. There are no complicated setting which is great for new users and great for adoption.
- (Zach) And the best part is, there were no fees at all for that transaction. In fact there have never been any transaction fees on the Nano network ever!
-(Admin) Great! That's why I wanted to share it with everyone, yesterday I could try the wallet and it is really spectacular to use, thank you very much for that excellent explanation, please stay with us, now comes the part in which our users participate
Segment 3, community questions
Q -First congratulations on your project, it is amazing. Now, does nano BlockChain have another use besides making transactions?
A - (Zach) Thank you! Nano has always been focused on transfer of value and will continue to maintain that focus. The overall design is aimed at doing only this so it can remain fast, efficient and fee-less.
Q -Good evening! I understand that thanks to its architecture called "Block-lattice", each individual provides the computing power necessary to verify their own transaction, thanks to this they do not use miners to confirm transactions and they do not apply commissions of any kind. My question is: How did this occur and how difficult was it?
A - (Colin) It’s simila, transactions are validated by votes from the representatives, not by the PoW. The PoW is a way to slow down how fast people can create transactions so they can’t spam the network.
Q - Do you have any short or long term projects so that transactions using $NANO were anonymous?
A - (Colin) Long term we want to see what privacy options exist and are fast. Most privacy schemes make the transactions very big or slow to process and it’s important for things to remain quick and efficient so we can have fast transactions.
Q - We are living in Venezuela many changes in the cryptocurrency sector, the integration of crypto for service payment and product purchases is already a reality. What agreements has NANO made with service stores to integrate it as a means of payment? I want to pay my movie ticket with NANOS
A - (Zach) Thanks for your interest in Nano. We are always looking for ways to allow everyone to use Nano in as many places as possible. Although separate from our organization, we are aware of the efforts of the Nano Venezuela organization and try to support them when possible in bringing Nano to as many people and stores in Venezuela as possible.
Q - (7 questions made from one persone at once)
