Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

  5. FAQ

1. What is Energi

Energi is a self-funding (no ICO and no premine) cryptocurrency that has a purpose to become the world’s leading cryptocurrency with the unification of Smart Contracts, Governance and Self-funding Treasury to ensure longevity and enable rapid growth. You can read more about why we decided to self-fund and chose not to conduct an ICO here.
Energi provides a small allocation to Proof-of-Stake (PoS) rewards, takes a bulk of the coin issuance and gives it to its treasury and active Masternodes. Energi also allocates 10% on-going reward to the leadership of the Energi Backbone, which is significantly less compared to today’s ICOs’ rewarding their founders between 20–50% of the tokens distributed. Another trait that sets Energi apart from ICOs is they give an on-going 10% allocation through each block reward, rather than rewarding the founders up-front.

2. What are the Fundamentals of Energi?

  • Scalability
1 minute block times and a 2 megabyte block size limit provide Energi with a vast transaction capacity for regular on-chain transactions. This allows for plenty of space on the blockchain for extremely fast transactions with very low fees.
Energi features a powerful on-chain scaling solution with a system of incentivized full nodes called Energi Masternodes. A Masternode is a full node backed by 1,000 NRG collateral that provides level 2 scalability to the Energi Cryptocurrency. 40% of the emissions of Energi is allocated to Masternodes, providing an extremely strong incentive to grow the number of full nodes and scalability of the network.

  • Funding
A key feature of Energi is its powerful treasury system. Energi makes up to 40% of the emissions available to the treasury, to be utilized in a manner that provides maximum benefit.
Treasury allocation is decentralized, allowing for submitted proposals from anyone, to be voted on by Masternodes and paid out from the emissions.
Energi has a 14 day treasury cycle, allowing quick payments for proposal authors and contributors, as well as strategic responsiveness to effective proposals. Energi is guided by the principle that every dollar spent from its funding model should yield more than one dollar of value in return. Thanks to a 14 day treasury cycle, the Energi team is able to measure results and respond quickly to changes in strategy.

  • Governance
The Energi Treasury is a decentralized governance model designed with Masternodes as caretakers, with voting rights on how to best utilize treasury funding.
This governance model reduces risk by allowing participation from everyone who holds 1,000 NRG as a Masternode. In this way, the Energi community can work together on how to best build the strategic direction of Energi.

  • Inflation
Energi Cryptocurrency has a simple rate of inflation at 1 million coins per month with no maximum cap. This ensures consistency in funding allocation, Masternode rewards, and PoS rewards, making the economics of the cryptocurrency more understandable for everyone who chooses to participate in Energi.
No coin supply limit ensures that Energi is prepared for the long term, avoiding “bubble” economics caused by dramatic early inflation that in most coins only serves to benefit founders ahead of increased adoption.

  • Distribution
Energi conducted a fair launch on April 14, 2018 with no ICO and no premine. Prior to launch, the Energi team gave a specific time and date for the launch of its main net, which its vibrant community eagerly awaited, so that mining could begin fairly, again avoiding centralization among the coin founders (It's important to note that Energi has transitioned from Proof-of-Work consensus to a Proof-of-Stake consensus).
Energi Masternode payments were designed to begin at block 216000, which occurred on September 18, 2018, almost 160 days after launch. This ensured time to list Energi on exchanges, and to grow the community, encouraging fair and equitable distribution before the extremely powerful Masternode rewards began. It is all too common for Masternode coins to feature a premine, which has the effect of centralizing distribution among the founders and early adopters.
From 2018 to 2020, Energi distributed nearly 4 million coins to users who contributed to spreading awareness of the project with social media activities about Energi, such as tweets, follows, and subscriptions on all major social media platforms.

  • Decentralization
Decentralized governance with Masternodes helps to ensure everyone is able to participate in Energi and help guide the project to achieve the best results. The change to the requirement to run a Masternode, from 10 000 NRG to 1 000 NRG, has allowed more people to be involved and boosted decentralization for the whole project.

  • Long Term Vision
All of the above features seamlessly work together in concert, to ensure that Energi is prepared for the long term. Rather than try to closely find a niche in the market, Energi is prepared to adapt and overcome all challenges for many years to come. Energi’s use case is that of a traditional cryptocurrency, such as Bitcoin. However, Energi’s strategy is to excel by avoiding the pitfalls of previous projects, while further utilizing and improving upon the most powerful ideas in the cryptocurrency space.

3. Coin Specs

Ticker: NRG
Block time: 1 minute.
Hashing Algorithm: Dagger-Hashimoto (similar to Ethereum).
Masternode requirements: 1,000 Energi.
Treasury cycle: Every 14 days.
Approximately 1 million Energi will be released per month. The allocations can be observed easily as “10/10/40/40.”
10% will go to the Energi Backbone.
10% to the PoS participants
40% to Masternodes.
40% to the Treasury.
Thus, for every block, allocations are: 2.28 Energi to the Backbone, 2.28 Energi to the PoS participants, 9.14 Energi to the Treasury, and 9.14 Energi to Masternodes.
Since Treasury allocations are paid in two-week cycles, they are made in lump sums of approximately 184,000 Energi every 14 days.
In order to allow for widespread distribution of Energi before Masternode payments began, Masternode rewards were delayed until day 150. This was to allow the airdrop campaign to be completed and ensure a large amount of NRG is spread out through the community. Until that point, Masternode rewards were redirected to the Treasury. Thus for the first 5 months, the Treasury gained approximately 368,000 Energi every two weeks (about 800k Energi per month). The airdrop campaign was designed to release ~4 million Energi to the community.

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants

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 de l'espace 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 Bitcoin SV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes - jusqu'à un "exit scam" presque garantie, 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 machine à états mondiale qui permet un déploiement facile de tokens et de contrats intelligents, mais le protocole Ethereum ne peut pas évoluer, et parmis les milliers de projets lancés, seule une poignée pourrait même être présentée comme avoir les ingrédients nécessaires pour 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 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 est 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 culturelle qu'ils ne comprennent pas. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève
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 le problème de la double dépense de tous les précédents systèmes de paiement électronique était le seul facteur limitant l'adoption d'une monnaie électronique fonctionnelle. Il était impossible de prouver exactement qui possédait quelles unités d'argent sur leurs registres distribués, de sorte que les systèmes ne pouvaient pas faire confiance, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé « preuve de travail». Il poste la question: qui a brûlé le plus de puissance de calcul pour résoudre des énigmes arbitraires 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. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des 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 sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils plantent. Sur un jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau, donc un plafond de 1 Mo de données pour chaque dix minutes de temps de transaction 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.
Pourquoi est-ce important?
Une seule et simple transaction 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 a plaidé pour un nombre de transactions au niveau de Visa, 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 pour rester un simple 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 de Bitcoin.
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 bitcoin 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 négocié sauf en grosses quantitées de toute façon. 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.
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.
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 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. Malheureusement, il est régi par des développeurs de logiciels 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 sera vendu. Les paiements avec BTC ou les transactions de toute nature 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 catégorisé pour 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.
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 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. En tant que seul réseau bitcoin totalement sans 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 aucun limite sauf l'esprit humain et l'esprit d'entreprise.
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 trompent sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie du récit de 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. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing 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 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?
Si vous ne le savez pas, 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 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 autres forums, et nouvellement financée 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 toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que 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 a investi une fortune incalculable 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 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 mondiales 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 petite preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, vraiment, 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 professionnelle. 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, ce que, franchement, Gmaxwell est.» - 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.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre anti-BSV est Calvin Ayre: le 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 de porcs, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu d'argent sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines compliquées et 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 une liste des «plus recherchés» 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 de délit, mais a été le fer de lance de la modernisation des lois et règlements américains qui existent aujourd'hui sur les marchés complètement ouverts et fonctionnels. Il est respecté pour son travail dans l'industrie du jeu, les médias et la philanthropie. Calvin est certainement le bienvenu aux États-Unis malgré la critique souvent citée et dépassée selon laquelle il est 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 pendant plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups dans l'espace BSV. Bien qu'il soit probablement le plus gros investisseur, il n'est pas le monolithe que les petits-blocs laisseraient croire aux critiques. 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. 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 Unwriter's Planaria Corp.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage. Alors qu'à un moment de l'histoire, les entreprises appartenant à Ayre représentent une quantité importante de hachage sur bitcoin, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup sont ennemis. Ces mineurs soulignent cependant la nature ouverte et sans permission de BSV pour permettre à quiconque de participer.
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 tout le monde 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 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. 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.
Cette ère de service a 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 publics 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 du tout cette version de bitcoin à la suite du drame public.
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 pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que des problèmes juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais les critiques publiques ont persisté jusqu'à ce que Roger soit également entendu devant le tribunal et fournisse la preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Son cas est en instance à Antigua-et-Barbuda, où il est récemment devenu citoyen.
Et ensuite il se passe quoi ?
Nous avons établi l'histoire du Bitcoin, de la 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 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 les orateurs Gary Vaynerchuk , et d'autres orateurs prévus afin de les forcer à annuler leur participation à la conférence. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un cas gigantesque de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin SV 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 classe mondiale. Il est utilisé par des entreprises indépendantes pour réaliser des profits et il est exploité sur le marché libre par 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 mondiaux. Les mensonges au contraire sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaie 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 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 dans les grandes 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 supérieure qui les rendrait obsolètes.

Actual cost of a 51% attach, $10.2 million

So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block.
Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Plugging the equations into excel produces the following (assuming t=10)
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51%
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left.
Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack.
Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network.
Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Specte Bond Promo Cost Hrs Blks Levrg / Block Reorg Leverage Rate Int Cost
51.00% 1.50% $1,155,743 8.497 25 $8,025,990 $208,675,743 20% $40,485
51.50% 2.50% $1,232,745 5.825 17 $8,025,990 $144,467,822 20% $19,215
52.50% 4.50% $1,336,143 3.492 10 $8,025,990 $88,285,891 20% $7,039
54.50% 7.50% $1,562,998 2.141 6 $8,025,990 $56,181,931 20% $2,746
58.50% 14.50% $2,023,385 1.140 3 $8,025,990 $32,103,960 20% $835
66.70% 33.30% $2,970,442 0.500 1 $8,025,990 $16,051,980 20% $183
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total.
1 - All "hashes" are hashes per second
2 - TH = 1012 or 10004 hashes per second
3 - EH = 1018 or 10006 hashes per second
4 - Assume a market rate of 0.101 USD / TH / day
5 - Assume an average daily network hashrate of 116.73 EH

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

A Glance at the Heart: Proof-of-Authority Technology in the UMI Network

https://preview.redd.it/vhvj6v093df51.jpg?width=1024&format=pjpg&auto=webp&s=00c0c223d9758edec8ed49a8cb9024f96d3ee343
Greetings from the UMI Team! Our Whitepaper describes in detail the key pros and cons of the two mechanisms which the great majority of other cryptocurrencies are based on:
Proof-of-Work (PoW) — mining technology. Used in Bitcoin, Ethereum, Litecoin, Monero, etc.
Proof-of-Stake (PoS) and its derivatives — forging technology. Used in Nxt, PeerCoin, NEO, PRIZM, etc.
As a result of a careful analysis of PoW and PoS, which are designed to fight against centralization, there came a conclusion that they both fail to perform their main mission and, in the long run, they lead to the network centralization and poor performance. For this reason, we took a different approach. We use Proof-of-Authority (PoA) algorithm coupled with master nodes, which can ensure the UMI network with decentralization and maximum speed.
The Whitepaper allows you to understand the obvious things. This article will give you a clear and detailed explanation of the technology implemented in the UMI network. Let's glance at the heart of the network right now.
Proof-of-Authority: How and Why It Emerged
It's been over a decade since the first transaction in the Bitcoin network. Over this time, the blockchain technology has undergone some qualitative changes. It's down to the fact that the cryptocurrency world seeing the emerging Proof-of-Work defects in the Bitcoin network year after year has actively searched for ways to eliminate them.
PoW decentralization and reliability has an underside of low capacity and scalability problem that prevents the network from rectifying this shortcoming. Moreover, with the growing popularity of Bitcoin, greed of miners who benefit from high fees resulting from the low network throughput has become a serious problem. Miners have also started to create pools making the network more and more centralized. The “human factor” that purposefully slowed down the network and undermined its security could never be eliminated. All this essentially limits the potential for using PoW-based cryptocurrencies on a bigger scale.
Since PoW upgrade ideas came to nothing, crypto community activists have suggested cardinally new solutions and started to develop other protocols. This is how the Proof-of-Stake technology emerged. However, it proved to be excellent in theory rather than in practice. Overall, PoS-based cryptocurrencies do demonstrate a higher capacity, but the difference is not as striking. Moreover, PoS could not fully solve the scalability issue.
In the hope that it could cope with the disaster plaguing all cryptocurrencies, the community came up with brand new algorithms based on alternative operating principles. One of them is the Proof-of-Authority technology. It was meant to be an effective alternative with a high capacity and a solution to the scalability problem. The idea of using PoA in cryptocurrencies was offered by Gavin Wood — a high-profile blockchain programmer and Ethereum co-founder.
Proof-of-Authority Major Features
PoA's major difference from PoW and PoS lies in the elimination of miner or forger races. Network users do not fight for the right to be the first to create a block and receive an award, as it happens with cryptocurrencies based on other technologies. In this case blockchain's operating principle is substantially different — Proof-of-Authority uses the “reputation system” and only allows trusted nodes to create blocks.
It solves the scalability problem allowing to considerably increase capacity and handle transactions almost instantly without wasting time on unnecessary calculations made by miners and forgers. Moreover, trusted nodes must meet the strict capacity requirements. This is one the main reasons why we have selected PoA since this is the only technology allowing to fully use super-fast nodes.
Due to these features, the Proof-of-Authority algorithm is seen as one of the most effective and promising options for bringing blockchain to various business sectors. For instance, its model perfectly fits the logistics and supply chain management sectors. As an outstanding example, PoA is effectively used by the Microsoft Azure cloud platform to offer various tools for bringing blockchain solutions to businesses.
How the UMI Network Gets Rid of the Defects and Incorporates the Benefits of Proof-of-Authority Method
Any system has both drawbacks and advantages — so does PoA. According to the original PoA model, each trusted node can create a block, while it is technically impossible for ordinary users to interfere with the system operation. This makes PoA-based cryptocurrencies a lot more centralized than those based on PoW or PoS. This has always been the main reason for criticizing the PoA technology.
We understood that only a completely decentralized product could translate our vision of a "hard-to-hit", secure and transparent monetary instrument into reality. Therefore, we started with upgrading its basic operating principle in order to create a product that will incorporate all the best features while eliminating the defects. What we’ve got is a decentralized PoA method. We will try to explain at the elementary level:
- We've divided the nodes in the UMI network into two types: master nodes and validator nodes.
- Only master nodes have the right to create blocks and confirm transactions. Among master node holders there's the UMI team and their trusted partners from across the world. Moreover, we deliberately keep some of our partners — those who hold master nodes — in secret in order to secure ourselves against potential negative influence, manipulation, and threats from third parties. This way we ensure maximum coherent and reliable system operation.
- However, since the core idea behind a decentralized cryptocurrency rules out any kind of trust, the blockchain is secured to prevent master nodes from harming the network in the event of sabotage or collusion. It might happen to Bitcoin or other PoW- or PoS-based cryptocurrencies if, for example, several large mining pools unite and perform a 51% attack. But it can’t happen to UMI. First, the worst that bad faith master node holders can do is to negligibly slow down the network. But the UMI network will automatically respond to it by banning such nodes. Thus, master nodes will prevent any partner from doing intentional harm to the network. Moreover, it will not be able to do this, even if most other partners support it. Nothing — not even quantum computers — will help hackers. Read our post "UMI Blockchain Six-Level Security" for more details.
- A validator node can be launched by any participant. Validator nodes maintain the network by verifying the correctness of blocks and excluding the possibility of fakes. In doing so they increase the overall network security and help master nodes carry out their functions. More importantly, those who hold validator nodes control those who hold master nodes and confirm that the latter don't violate anything and comply with the rules. You can find more details about validator nodes in the article we mentioned above.
- Finally, the network allows all interested users to launch light nodes (SPV), which enables viewing and sending transactions without having to download the blockchain and maintain the network. With light nodes, any network user can make sure if the system is operating properly and doesn't have to download the blockchain to do this.
- In addition, we are developing the ability to protect the network in case 100% of the master nodes (10,000 master nodes in total) are "disabled" for some reason. Even this is virtually impossible, we've thought ahead and in the worst-case scenario, the system will automatically move to PoS. By doing so, it will be able to continue processing transactions. We're going to tell you about this in our next publications.
Thus, the UMI network uses an upgraded version of this technology which possesses all its advantages with drawbacks eliminated. This model is truly decentralized and maximum secured.
Another major drawback of PoA-based cryptos is no possibility to grant incentives to users. PoA doesn't imply forging or mining which allow users to earn cryptocurrency while generating new coins. No reward for maintaining the network is the main reason why the crypto community is not interested in PoA. This is, of course, unfair. With this in mind, the UMI team has found the best solution — the unique staking smart-contract. It allows you to increase the number of your coins up to 40% per month even with no mining or forging meaning the human factor cannot have a negative impact on the decentralization and network performance.
New-Generation Proof-of-Authority
The UMI network uses an upgraded version of PoA technology which possesses all its advantages with drawbacks virtually eliminated. This makes UMI a decentralized, easily scalable, and yet the most secure, productive, profitable and fair cryptocurrency, working for the sake of all people.
The widespread use of UMI can change most aspects of society in different areas, including production, commerce, logistics, and all financial arrangements. We are just beginning this journey and thrilled to have you with us. Let's change the world together!
Best regards, UMI Team!

A practical proposition to naturally make bitcoin better.

So I thought of an idea, if bitcoin has introduced the key concept of mining and exchanging gold into the internet, how about making also the concept of minting into coin with weight and purity also to it too? Like gold or silver, when we mine them we weight mined raw metal in grams or ounce and each little rocks have different purity. Those raw metal do have value but still is hard to transact with them (I believe we are like in this situation for bitcoin; we mine satoshis and the fees and price are constantly fluctuating.). To make economic exchange of those raw metal easy, we mint the raw metals into coins in a standard size, weight and purity.
Example the 1 oz 22 karats American Eagle gold coin. 22 Karat mean the coin has 91.67% pure gold and 8.33% is impurity. How about we present the equivalent concept for Bitcoin, we imagine a virtual coin with defined purity and weight? If we agree a virtual coin unit, let's call it vBTC, have always 0.2% average fee, and from that calculate the weight of 1 vBTC in satoshi?
The time writing this the price of bitcoin is 8,915.00 USD and the average fee is around 2.41 USD/TX or 27,500 satoshi/TX that 1 vBTC will have the weight of 27,500/0.002 = 13,750,000 satoshis value $1,223.09. And each day or bloc that weight go down or go up according to the network load. (here I chose the 0.2% fee because we can use sub unit, like 0.01 vBTC which have 20% fee if we desire it in the first bloc. or let it 0.2% if to be on any bloc) And when I send you a 1 vBTC, I don't worry about fees if is high or low, or if my coin will be in the block or not. 1 vBTC will always be in the next block. If a seller set a price in vBTC, like a software for 2.5 vBTC, if the network is loaded or not, if the price is up or down it doesn't matter. When I receive 2.5 vBTC, I know I own 99.8% of that and i will receive it at the next 10min.
We can do this without changing anything in the bitcoin protocol. It's just a virtual layer between us bitcoin users. This way we can separate the link between bitcoin and USD and all those prices speculators in those centralized exchange platforms. And use bitcoin as a way of exchange, not an asset that we just hold and wait the day it hit the moon.
Yet there is still another stunning thing we can do with that vBTC. It can solve the price fluctuation nightmare of bitcoin.
The time writing this 1 vBTC is 13,750,000 satoshis which is $1,223.09 and 1oz 22K American Eagle gold coin is around $1,766.50, which are approximately the similar level of value. How about if we say that 1 vBTC possess the same intrinsic value as a 1 oz of 22K gold coin? Like anywhere and anytime 1 vBTC can always be exchanged to 1oz of 22K gold coin? And we always transact 1 vBTC as was real 1oz 22K gold on internet?
It's a very hard to understand at first glance, but allow me to explain. Right now, the price of normal BTC is set by the law of supply and demand in those multiple centralized exchange platforms. If there is more buyers than sellers, the price go up, and if there is more sellers than buyers, the price go down. But that supply and demand system is already present on the vBTC. If there is more demand (load) on the network the average fees go up and the weight of 1 vBTC in satoshis go up too. If there is less, the fees go down and the weight of 1 vBTC go down too. So if we simply agree that 1 vBTC = 1 oz 22K Gold, the bitcoin network by itself will do all the work and converge to the perfect weight to accommodate that value equality at that exact time. And that without letting speculator decide the price of it in a fiat currency on those centralized exchange platforms.
This will be revolutionary. There will be no speculation what so ever, and no pricing in a Fiat currency and no anxious holding until hit the moon. We can see bitcoin as simple coins and we can price our goods and services as old time when gold minted coins was introduced. And this doesn't require any change in bitcoin protocol. All it needs is only we put the vBTC denomination into wallets and we all bitcoin users have the faith that 1 vBTC = 1 oz 22K Gold or arround that, and the bitcoin network will do the magic by itself.
Furthermore, this is a good way to make minting of real physical 1 vBTC in real 1oz 22K gold possible, and exchange as it was real bitcoins we touch with hands.
I will seek first to perform some excel spreadsheet calculation of the above. As the weight variation of vBTC (0.2% fees) since 2011 and price of each 1 vBTC in 1 oz Gold since 2011 then share it here.

Presented visually, below is a high-level view of the current asset allocation of the portfolio.
Comments
This month saw exceptional growth in the portfolio, with a net increase of $94 000 after a small fall last month.
[Chart]
This is the fastest growth in the past half year. It is also the second largest absolute increase in over three years of measurement.
[Chart]
As the histogram below - which counts the frequency of occurrences in a specified range of monthly value changes (with red denoting losses) - makes clear, this is one of the most positive outcomes in the three year record.
[Chart]
The sources of portfolio growth were generally buoyant global and Australian share markets. Just under half of the growth was also due to an increase in the price of both gold securities and Bitcoin. In addition, even bond holdings increased in value over the period.
Distribution payments from the Vanguard retail funds, as well as the exchange-traded funds VAS, VGS and A200 were made through this month.
These totalled around $14 000 and have begun to be gradually fed back into the portfolio. This is a process which will occur through to June - with new investments twice per month. So far this has led to additional purchases in Vanguard's Australian shares exchange-traded fund (VAS) to maintain the target allocation of Australian equities making up 60 per cent of all equity holdings.
The bond allocation of the portfolio continues to be notionally under its target, but has not yet reached a position where further balancing investments are warranted. Fully excluding the value of Bitcoin, for example, it still sits on its target allocation of 15 per cent of the portfolio.
If the same calculation is done for equities, they sit just above their target, at 77 per cent, and have drifted higher since early last year. Over the past months my position has been to take no portfolio balancing actions based purely on the volatile value of Bitcoin over time, and this remains my approach.
There is no perfect answer to this issue - assigning no value to Bitcoin and ignoring it for asset allocation purposes is inconsistent with its role in the portfolio. Pushing either equity or bond allocations sharply out of target boundaries merely due to short-term Bitcoin movements is also not warranted. Taking a backcast 'moving average' approach might be one statistical solution, but I am not yet convinced it would do more than moderate the appearance of the issue.
While expenditure has been higher over the holiday period, on average the gap between the rolling three-year average of distributions and credit card expenditure continues to close, and sits at just over a $300 per month gap at present.
Flags of convenience - estimating hedging in the portfolio
This month, out of a curiosity carried over from my recent review of my bond holdings, I have found the time to review of the overall currency hedging position of the portfolio.
There are some excellent online research papers (pdf) and blog pieces, such as this one from Passive Investing Australia, for those interested in learning more about some of the associated issues.
Currency risks have never previously been an object of much detailed thought on the journey. Rather, I had tracked a basic measure of broader exposure to foreign assets (including foreign equities, property securities, gold and more recently Bitcoin).
The additional issue of whether my exposure to these assets was unhedged (meaning exposure to gains and losses from the relative movement in the Australian dollar and the foreign currencies) or hedged was not really front of mind.
I suppose I had a dim awareness that some elements of the Vanguard retail funds that have until recently dominated the portfolio were hedged (for example, around 30 per cent of the Vanguard High Growth Diversified funds equity position is currency hedged), and judged that there was likely a well-considered rationale behind the amount of this hedging.
The first step to understanding where any exposures exist is to understand and measure the current state of affairs. As of today, this is broadly as set out below:
The decision to invest in Vanguard's International Shares ETF (VGS), which is unhedged, is a significant event in this regard.
The chart below shows the overall level of currency hedging in the international equity portfolio. Investments in VGS commenced from July 2019, and have started to affect the level of hedging.
[Chart]
As future contributions flow into VGS - absent any other action - a historically quite stable level of hedging will continue to fall. So far this is just a trend I am monitoring, until I have completed more research and thinking on the best approach in this area.
There are many complicated, and some unknowable, issues to consider and balance in hedging decisions, such as the likely denomination of future costs, and the historical and future relationships between domestic currencies and equity markets. None avail themselves of short or easy answers. Until I have thought my way through them more fully, I remain hesitant to make any definitive decisions.
Progress
Progress against the objective, and the additional measures I have reached is set out below.
Measure Portfolio All Assets
Portfolio Objective – $2 180 000 (or $87 000 pa) 85.2% 115.9%
Credit card purchases – $71 000 pa 103.9% 141.4%
Total expenses – $89 000 pa 83.3% 113.3%
Summary
This month has seen rapid progress, propelling the portfolio closer to both old and new goals. The portfolio gains this month have already closed nearly half of the additional distance created by increasing my portfolio target at the beginning of the year.
The psychological forward push from distributions performance across 2019 (including, pleasingly, seeing it recognised here) has added to this sense of momentum. Additionally, this month I have also crossed the threshold to the target portfolio size needed to achieve 'credit card FI', a long-standing measure I have tracked.
The long summer break that has just ended in some ways seemed like a foretaste of what some versions of financial independence could feel like. With the minimum of planning there was time to read, rest, exercise and write largely as I pleased.
Returning to work following this has been infused with an unusual sense of being a temporary visitor in a new workplace. There is a greater philosophical detachment, in observing its rituals and rhythms, and less of a desire to seek to shape or resist its minutiae. Rather, what I have focused on is seeking to more deliberately make use of the freedoms it does not constrain, and pursue the best and most interesting use of the time that is outside of work hours.
Through these recent strong Australian and US equity markets, this article has been a useful reminder of the 'survivorship' risks of focusing a FI target too narrowly on past performance.
This excellent recent piece from Aussie HIFIRE has also, from another direction, usefully focused on separating out the decisions that do, and do not, materially matter in planning and executing on a passive indexing strategy over the long-term. For a challenging and entirely heterodox view on the potential long-term movement of equity markets upwards from here, this article has been thought-provoking.
Finally, this month I have been discovering the Jolly Swagman podcast, which has long and fascinating interviews with the ex-head of the Reserve Bank of Australia, and Nobel Prize winning US economist Robert Shiller speaking on bubbles and narrative economics.
During the long restful hours of summer break, the day has advanced. Though clouds may come in time, as the year starts - at least - the way forward looks bright.

Will a Ryzen 3900x be compatible with new gen GPUs this year?

Does someone who knows more about computers please answer my question.
From my research it seems that most GPUs dont fully utilize the cores on a CPU for gaming as that's more for video editing and calculations.
I wanted to get the 3900x as I want to get good performance while gaming and streaming at the same time. After my 3 year warranty expires I was going to de lid my CPU and put thermal grizzly liquid metal on it to get better cooling and OC it even more if possible.
I'm kind of new to all of this and am curious if I put the equivalent of a 3080 ti on a b450 max MOBO with this CPU or the Big Navi AMD 3080 Ti competitor would I be bottle necking my GPU due to my CPU not being powerful enough?
And should I not be an idiot and just wait for the new Ryzen CPU release and just go hard and future proof my build come September and October.
I intend to only use this PC for Excel, video conferences, and my hobby gaming and streaming. Maybe dabble in some bitcoin mining. I don't mind dropping 2 grand if that means I won't have to upgrade for the next 5-7 years and will have solid performance. But of course would love to save money where I can.

8 times of online appreciation, only GFS will rise in 2020

8 times of online appreciation, only GFS will rise in 2020

https://preview.redd.it/dftun04vml451.png?width=724&format=png&auto=webp&s=f0c667cbc5d0de39f0bf113e9941b0c7f9cb072f
GFS over 8 times in two weeks!
With the continuous improvement of blockchain technology status, digital currency is being sought after by investors, bitcoin, Ethereum and other major mainstream currencies are rising, the certificate GFS of Forbes, the blockchain 4.0 cross chain protocol system, has also broken by $0.8, and the GFS online has increased by more than 8 times in less than two weeks, becoming the best investment target worthy of 2020!
■ global financial market downturn, digital currency is good
The financial market in 2020 can be described as double hot and cold days, with a sudden outbreak of a new crown epidemic and frequent black swans. In March, the U.S. stock market fused four times in 10 days, the Brazilian stock index fused, the Canadian S & P / TSX stock index fused, the crude oil futures fell to a negative number, and the panic of investors spread in the financial markets of various countries.
On the other hand, through a series of major events such as the Fed's interest rate cut, the global outbreak, and the stock market circuit breaker, the risk aversion of digital currency is becoming more and more obvious. In terms of supervision, under the favorable national policies of the United States, Singapore, Japan, India and other countries, the digital currency is being sought after by investors.
■ GFS up to 800%, or the first 100 times in 2020
All of the above have laid the foundation for a new round of bull market of digital currency, with major mainstream currencies rising one after another. In 2020, the well deserved king of digital assets is cross chain commercial blockchain Forbes, whose token GFS has been online for less than two weeks, has risen more than eight times, surpassing all mainstream digital assets.
The rise of GFS is nothing more than normal. A good digital asset, in addition to having excellent technology, its blockchain itself must solve practical problems, as an incentive means of digital assets to have value. Bitcoin provides a secure and stable decentralized bookkeeping system, while BTC, as the digital asset of bitcoin blockchain, is used as bookkeeping fee, so BTC can be the number one in digital currency. BTC has a stable use and use scenario, and the rise is natural.
■ Growth Logic of GFS
From a technical point of view, Forbes brings a brand-new blockchain financial ecology, which creates a truly usable cross chain ecology, helps traditional industries, especially the financial industry, realize chain reform, and makes various commercial applications run smoothly on Forbes. The core technology of Forbes is cross chain.
Great projects must have great genes. Forbes is co sponsored by cryptopunk members and some Wall Street practitioners. As we all know, Nakamoto, the initiator of bitcoin, is from cryptopunk forum. In addition, Wikileaks founder Assange is also from cryptopunk. Forbes team recognized that in the current blockchain field, due to the status quo of isolated islands between chains, the blockchain financial business could not be carried out. Cross chain is the top priority.
From the strategic layout shown in the Forbes white paper, GFS clearly has long-term investment value. At present, GFS has created typical applications including: Forbes cross chain protocol, dpoc mining machine, Forbes Global Mining pool, one-stop digital asset storage management wallet Forbes wallet, etc. Any of these combined with the cross chain technology breakthrough of Forbes will give birth to a new and solid landing to realize the benign circulation of GFS in the ecosystem.
In the future, the great ecosystem of blockchain business application will be built on the basis of Forbes, including but not limited to decentralized exchanges, blockchain securities market, supply chain, payment management consumption application, lending, food, clothing, housing and so on.
■ infinite GFS potential, thousands of times of value
At present, the global financial assets have encountered black swan, and the overall market is relatively low. However, Forbes' new ecosystem across the region has demonstrated its ability to resist risks. As one of the most anticipated projects in 2020, GFS has obvious advantages over other projects. First of all, GFS is not a one click token. As the fuel consumed in the cross chain process, GFS uses dpoc, a common algorithm for hard disk mining. The total amount is constant 21 million, no additional issue is allowed! No team pre excavation! GFS is 100% mineral currency, and the biggest feature of mineral currency is the anchoring mining cost. For example, the current price of bitcoin is 8500u. A large part of the reason is that the mining machine, power and other costs are 7000u. The digital currency with the support of calculation is really valuable.
Secondly, we should mention the ecological application of GFS. According to the project white paper, GFS's main uses are:
  1. Main chain gas. It's easy to understand that any node transferring money on the GFS blockchain needs to pay gas just like bitcoin, which is a long-term demand. As Forbes blockchain involves cross chain, transfer between main networks is indispensable, and the daily gas fee is absolutely not low.
  2. Cross chain gas, that's great. To initiate cross chain transfer, cross chain transaction and cross chain data transmission on Forbes, the nodes need to pay part of GFS as cross chain gas. Many Xiaobai don't understand the value of cross chain landing. Let's give a random example: the exchange. At present, the exchange is generally centralized, and it needs to pay a handling fee for one purchase and one sale, which is very high (22-55). Therefore, several large domestic exchanges have made a lot of money. However, if the cross chain transaction is decentralized through Forbes' cross chain system, the handling fee only needs to be paid once, and the fee is only 1 / 100 to 1 / 1000 of the current fee, which will bring a revolution to the exchange from abroad. How much revenue will Forbes get from this alone? Let alone the handling fees of financial derivatives such as futures and options. The realization of cross chain is likely to unify the encrypted financial market. Think of Ethereum, because of the creation of smart contracts, the price has doubled 10000 times in five years. How about cross chain GFS? I can't imagine.
  3. DAPP fees, it is self-evident that DAPP will replace the centralized app in the future. The reason why DAPP can't develop now is obvious. It can't cross the chain! Can DAPP over Ethernet be switched to EOS? Can users on both sides use the same set of account books? No, it needs to be solved by Forbes cross chain protocol. Similarly, Forbes charges a small fee for GFS. But in such a large market, there is definitely a lot of money.
  4. In addition to the application of GFS, the mining pool has the function of early securities pass, that is, holding GFS would like to have the mining pool income dividend, what is the point? Bitcoin. At present, the number one digital asset is a solid hard currency.

https://preview.redd.it/p56gxe2fnl451.png?width=1307&format=png&auto=webp&s=c2dde5f4df4dca8a3e98967b8b26538660a034fa
Not to mention the influence of cross chain stable currency kusd and the high-speed growth brought by the small amount of circulation in the early stage of the project. Forbes will land on at least 10 secondary market exchanges in 2020, according to officials. In 2021, it will be listed in one of the three exchanges. At present, one of the three exchanges has reached in-depth cooperation with Forbes. The global ecosystem on the chain, as well as the real industry in the distribution, have become the support of GFS value. Therefore, GFS currently shows a far higher yield than other currencies. According to the professional estimates of rating agencies, the growth rate of GFS this year is about 180 - 900 times.
It is worth noting that, according to the latest official news, the Forbes miner alliance plan has been launched. In the early nodes, Forbes mining pool can be set up, free participation in computing lease, zero cost mining and GFS reward can be obtained. It only needs to mortgage a certain amount of deposit, and the deposit is returned through the smart contract every day, and the income of 2.8 times the amount of deposit is obtained. To form a group of miners, you can also get corresponding recommendation rewards.
Within two weeks after the launch, it has soared more than 8 times, representing that Forbes cooperative enterprises and communities are all optimistic about its future performance. In fact, Forbes technology has been highly recognized by global communities, nodes, global mining pools and head exchanges. The popularity of Forbes is expanding step by step. Forbes has ignited the enthusiasm of the community and investors. The liquidity in the ecosystem is developing well, and its value is expected to be thousands of times.

2020, Forbes, only up!

It means that we have a common goal — to make the world of crypto gambling better! We know that players are especially interested in the convenience and openness of the platform.

How does fairness work on the BetFury platform?

Every bet on BetFury is absolutely random. How are you supposed to know that? It’s a fair question! Let’s look at one case of Dice, where the random number generator chooses the winning number from 0 to 99 and preferred by user range will define the reward.
  • Let’s say we think the winning number is less than 50;
  • Random Lucky result generated and mixed with random Server seed for every bet (in this round, the number 18 was encrypted in a hash). Hash sum of this mixing is shown for the user in the time of each turnover of the game. In this case, the hash you can see under the yellow Bet button.
https://preview.redd.it/pcsrdp7a86t41.png?width=1276&format=png&auto=webp&s=8d497acf93567ea8ede679cb4752d5bb8fd2c2fd
  • The provably fair principle is based on SHA256 technology the same as Bitcoin.
  • You can check the result by clicking the “Fairness” in the window of the game and find the result of each bet.

The new cryptocurrency "ETX" is been mining, its technology and potential have attracted much attention!

The new cryptocurrency
As the culmination of a new round of information technology innovation, the application of blockchain in the economic industry is pushing the entire economic system to achieve technological change, organizational change and efficiency change. The implementation of blockchain technology will bring the existing business model Refactoring. Among them, Bitcoin, as a representative of blockchain technology, has been in operation for 11 years from 2009 to the present. It has survived some crises and has been constantly improving and upgrading.
On January 3, 2009, the first block: the genesis block was born, the first miner and bitcoin owner: Satoshi Nakamoto, the reward generated by the first block: 50 bitcoins. This also means that the formal birth of blockchain technology and digital currency has historical significance for today's digital currency market.

https://preview.redd.it/uyjjvx99ars41.jpg?width=640&format=pjpg&auto=webp&s=0141ed26e5c38e4bd9fc610a13b4339f84656378
In the process of continuous development and improvement of the blockchain, many more excellent digital currencies have emerged, both from the technical level and the future vision, they all have relatively good performance. ETX (EthereumX-NET) is one of them, and it has been loved by digital currency enthusiasts in the early days of its birth. ETX public chain adopts a brand-new blockchain system architecture and is positioned as an easy-to-use high-performance blockchain platform designed to achieve the performance expansion of distributed applications to meet the real needs of the real world.
In order to reduce the pressure on the main chain, ETX (EthereumX -NET) adopts a layered architecture of main chain + side chain. The main chain is only responsible for the circulation of ETX. DAPP runs on the side chain and completes the safe transfer of value between the main chain and the side chain through the ETX side chain transfer mechanism. The ETX public chain uses the mechanism of arbitrators' joint signature to ensure the security of transfers with the side chain. The main chain's currency holders jointly elect a certain number of "arbitrators". By signing, most arbitrators' signatures can unlock transactions on the main chain from the account representing the side chain to the ordinary account.

The ETX (EthereumX-NET) ecosystem has mining with a diversified main chain, and further releases the value of computing power through technology to bring higher returns to customers. In other words, these calculations can be used to do other things. Secondly, the ETX mining pool provides a one-stop node mining service for the mining pool for the main chain of ETX relying on the PoW + DPoS consensus mechanism. Election to the ETX mining pool seed node is the first step in mining ETX mining pool nodes. Next, the ETX mining pool will launch more node mining services under the PoW + DPoS consensus mechanism. At that time, miners can participate in mining and obtain mining rewards only by proxy voting.

Bitcoin Original: Reinstate Satoshi's original 32MB max blocksize. If actual blocks grow 54% per year (and price grows 1.54^2 = 2.37x per year - Metcalfe's Law), then in 8 years we'd have 32MB blocks, 100 txns/sec, 1 BTC = 1 million USD - 100% on-chain P2P cash, without SegWit/Lightning or Unlimited

TL;DR
Details
(1) The current observed rates of increase in available network bandwidth (which went up 70% last year) should easily be able to support actual blocksizes increasing at the modest, slightly lower rate of only 54% per year.
Recent data shows that the "provisioned bandwidth" actually available on the Bitcoin network increased 70% in the past year.
If this 70% yearly increase in available bandwidth continues for the next 8 years, then actual blocksizes could easily increase at the slightly lower rate of 54% per year.
This would mean that in 8 years, actual blocksizes would be quite reasonable at about 1.548 = 32MB:
Hacking, Distributed/State of the Bitcoin Network: "In other words, the provisioned bandwidth of a typical full node is now 1.7X of what it was in 2016. The network overall is 70% faster compared to last year."

http://hackingdistributed.com/2017/02/15/state-of-the-bitcoin-network/
Reinstating Satoshi's original 32MB "max blocksize" for the next 8 years or so would effectively be similar to the 1MB "max blocksize" which Bitcoin used for the previous 8 years: simply a "ceiling" which doesn't really get in the way, while preventing any "unreasonably" large blocks from being produced.
As we know, for most of the past 8 years, actual blocksizes have always been far below the "max blocksize" of 1MB. This is because miners have always set their own blocksize (below the official "max blocksize") - in order to maximize their profits, while avoiding "orphan" blocks.
This setting of blocksizes on the part of miners would simply continue "as-is" if we reinstated Satoshi's original 32MB "max blocksize" - with actual blocksizes continuing to grow gradually (still far below the 32MB "max blocksize" ceilng), and without introducing any new (risky, untested) "game theory" or economics - avoiding lots of worries and controversies, and bringing the community together around "Bitcoin Original".
So, simply reinstating Satoshi's original 32MB "max blocksize" would have many advantages:
  • It would keep fees low (so users would be happy);
  • It would support much higher prices (so miners would be happy) - as explained in section (2) below;
  • It would avoid the need for any any possibly controversial changes such as:
    • SegWit/Lightning (the hack of making all UTXOs "anyone-can-spend" necessitated by Blockstream's insistence on using a selfish and dangerous "soft fork", the centrally planned and questionable, arbitrary discount of 1-versus-4 for certain transactions); and
    • Bitcon Unlimited (the newly introduced parameters for Excessive Block "EB" / Acceptance Depth "AD").
(2) Bitcoin blocksize growth of 54% per year would correlate (under Metcalfe's Law) to Bitcoin price growth of around 1.542 = 2.37x per year - or 2.378 = 1000x higher price - ie 1 BTC = 1 million USDollars after 8 years.
The observed, empirical data suggests that Bitcoin does indeed obey "Metcalfe's Law" - which states that the value of a network is roughly proportional to the square of the number of transactions.
In other words, Bitcoin price has corresponded to the square of Bitcoin transactions (which is basically the same thing as the blocksize) for most of the past 8 years.
Historical footnote:
Bitcoin price started to dip slightly below Metcalfe's Law since late 2014 - when the privately held, central-banker-funded off-chain scaling company Blockstream was founded by (now) CEO Adam Back u/adam3us and CTO Greg Maxwell - two people who have historically demonstrated an extremely poor understanding of the economics of Bitcoin, leading to a very polarizing effect on the community.
Since that time, Blockstream launched a massive propaganda campaign, funded by $76 million in fiat from central bankers who would go bankrupt if Bitcoin succeeded, and exploiting censorship on r\bitcoin, attacking the on-chain scaling which Satoshi originally planned for Bitcoin.
Legend states that Einstein once said that the tragedy of humanity is that we don't understand exponential growth.
A lot of people might think that it's crazy to claim that 1 bitcoin could actually be worth 1 million dollars in just 8 years.
But a Bitcoin price of 1 million dollars would actually require "only" a 1000x increase in 8 years. Of course, that still might sound crazy to some people.
But let's break it down by year.
What we want to calculate is the "8th root" of 1000 - or 10001/8. That will give us the desired "annual growth rate" that we need, in order for the price to increase by 1000x after a total of 8 years.
If "you do the math" - which you can easily perform with a calculator or with Excel - you'll see that:
  • 54% annual actual blocksize growth for 8 years would give 1.548 = 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 * 1.54 = 32MB blocksize after 8 years
  • Metcalfe's Law (where Bitcoin price corresponds to the square of Bitcoin transactions or volume / blocksize) would give 1.542 = 2.37 - ie, 54% bigger blocks (higher volume or more transaction) each year could support about 2.37 higher price each year.
  • 2.37x annual price growth for 8 years would be 2.378 = 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 * 2.37 = 1000 - giving a price of 1 BTC = 1 million USDollars if the price increases an average of 2.37x per year for 8 years, starting from 1 BTC = 1000 USD now.
So, even though initially it might seem crazy to think that we could get to 1 BTC = 1 million USDollars in 8 years, it's actually not that far-fetched at all - based on:
  • some simple math,
  • the observed available bandwidth (already increasing at 70% per year), and
  • the increasing fragility and failures of many "legacy" debt-backed national fiat currencies and payment systems.
Does Metcalfe's Law hold for Bitcoin?
The past 8 years of data suggest that Metcalfe's Law really does hold for Bitcoin - you can check out some of the graphs here:

(3) Satoshi's original 32MB "max blocksize" would provide an ultra-simple, ultra-safe, non-controversial approach which perhaps everyone could agree on: Bitcoin's original promise of "p2p electronic cash", 100% on-chain, eventually worth 1 BTC = 1 million dollars.
This could all be done using only the whitepaper - eg, no need for possibly "controversial" changes like SegWit/Lightning, Bitcoin Unlimited, etc.
As we know, the Bitcoin community has been fighting a lot lately - mainly about various controversial scaling proposals.
Some people are worried about SegWit, because:
  • It's actually not much of a scaling proposal - it would only give 1.7MB blocks, and only if everyone adopts it, and based on some fancy, questionable blocksize or new "block weight" accounting;
  • It would be implemented as an overly complicated and anti-democratic "soft" fork - depriving people of their right to vote via a much simpler and safer "hard" fork, and adding massive and unnecessary "technical debt" to Bitcoin's codebase (for example, dangerously making all UTXOs "anyone-can-spend", making future upgrades much more difficult - but giving long-term "job security" to Core/Blockstream devs);
  • It would require rewriting (and testing!) thousands of lines of code for existing wallets, exchanges and businesses;
  • It would introduce an arbitrary 1-to-4 "discount" favoring some kinds of transactions over others.
And some people are worried about Lightning, because:
  • There is no decentralized (p2p) routing in Lightning, so Lightning would be a terrible step backwards to the "bad old days" of centralized, censorable hubs or "crypto banks";
  • Your funds "locked" in a Lightning channel could be stolen if you don't constantly monitor them;
  • Lighting would steal fees from miners, and make on-chain p2p transactions prohibitively expensive, basically destroying Satoshi's p2p network, and turning it into SWIFT.
And some people are worried about Bitcoin Unlimited, because:
  • Bitcoin Unlimited extends the notion of Nakamoto Consensus to the blocksize itself, introducing the new parameters EB (Excess Blocksize) and AD (Acceptance Depth);
  • Bitcoin Unlimited has a new, smaller dev team.
(Note: Out of all the current scaling proposals available, I support Bitcoin Unlimited - because its extension of Nakamoto Consensus to include the blocksize has been shown to work, and because Bitcoin Unlimited is actually already coded and running on about 25% of the network.)
It is normal for reasonable people to have the above "concerns"!
But what if we could get to 1 BTC = 1 million USDollars - without introducing any controversial new changes or discounts or consensus rules or game theory?
What if we could get to 1 BTC = 1 million USDollars using just the whitepaper itself - by simply reinstating Satoshi's original 32MB "max blocksize"?
(4) We can easily reach "million-dollar bitcoin" by gradually and safely growing blocks to 32MB - Satoshi's original "max blocksize" - without changing anything else in the system!
If we simply reinstate "Bitcoin Original" (Satoshi's original 32MB blocksize), then we could avoid all the above "controversial" changes to Bitcoin - and the following 8-year scenario would be quite realistic:
  • Actual blocksizes growing modestly at 54% per year - well within the 70% increase in available "provisioned bandwidth" which we actually happened last year
  • This would give us a reasonable, totally feasible blocksize of 1.548 = 32MB ... after 8 years.
  • Bitcoin price growing at 2.37x per year, or a total increase of 2.378 = 1000x over the next 8 years - which is similar to what happened during the previous 8 years, when the price went from under 1 USDollars to over 1000 USDollars.
  • This would give us a possible Bitcoin price of 1 BTC = 1 million USDollars after 8 years.
  • There would still be plenty of decentralization - plenty of fully-validating nodes and mining nodes), because:
    • The Cornell study showed that 90% of nodes could already handle 4MB blocks - and that was several years ago (so we could already handle blocks even bigger than 4MB now).
    • 70% yearly increase in available bandwidth, combined with a mere 54% yearly increase in used bandwidth (plus new "block compression" technologies such as XThin and Compact Blocks) mean that nearly all existing nodes could easily handle 32MB blocks after 8 years; and
    • The "economic incentives" to run a node would be strong if the price were steadily rising to 1 BTC = 1 million USDollars
    • This would give a total market cap of 20 trillion USDollars after about 8 years - comparable to the total "money" in the world which some estimates put at around 82 trillion USDollars.
So maybe we should consider the idea of reinstating Satoshi's Original Bitcoin with its 32MB blocksize - using just the whitepaper and avoiding controversial changes - so we could re-unite the community to get to "million-dollar bitcoin" (and 20 trillion dollar market cap) in as little as 8 years.
