BitcoinLe 'Bitcoin' (₿, BTC, XBT) (de l'anglais bit : unité d'information binaire et coin ) est une cryptomonnaie autrement appelée monnaie cryptographique. Dans le cas de la dénomination unitaire, on l'écrit et, dans le cas du système de paiement pair-à-pair on l'écrit . L'idée fut présentée pour la première fois en novembre 2008 par une personne, ou un groupe de personnes, sous le pseudonyme de Satoshi Nakamoto. Le code source de l'implémentation de référence fut quant à lui publié en 2009.
Organisation autonome décentraliséeUne organisation autonome décentralisée ou DAO (de l’anglais decentralized autonomous organization) est une organisation qui se fixe une mission et qui fonctionne grâce à un ensemble de smart contracts permettant d'établir et de fournir des règles de gouvernance à une organisation. Ces règles sont transparentes et immuables car inscrites dans un réseau blockchain, une technologie de stockage et de transmission d’informations, transparente, sécurisée, et fonctionnant sans organe central de contrôle.
Self-interestSelf-interest generally refers to a focus on the needs or desires (interests) of one's self. Most times, actions that display self-interest are often performed without conscious knowing. A number of philosophical, psychological, and economic theories examine the role of self-interest in motivating human action. Individuals may have a self-serving bias towards their self-interest. Philosophical concepts concerned with self-interest include: Enlightened self-interest, a philosophy which states that acting to further the interests of others also serves one's own self-interest.
Proof of authorityProof of authority (PoA) is an algorithm used with blockchains that delivers comparatively fast transactions through a consensus mechanism based on identity as a stake. The most notable platforms using PoA are VeChain, Bitgert, Palm Network and Xodex. In PoA-based networks, transactions and blocks are validated by approved accounts, known as validators. Validators run software allowing them to put transactions in blocks. The process is automated and does not require validators to be constantly monitoring their computers.
Rational egoismRational egoism (also called rational selfishness) is the principle that an action is rational if and only if it maximizes one's self-interest. As such, it is considered a normative form of egoism, though historically has been associated with both positive and normative forms. In its strong form, rational egoism holds that to not pursue one's own interest is unequivocally irrational. Its weaker form, however, holds that while it is rational to pursue self-interest, failing to pursue self-interest is not always irrational.
