Elle est la technologie au coeur du Web Decentralis\u00e9 et de son corollaire, la finance d\u00e9centralis\u00e9e. Par extension, une blockchain constitue une base de donn\u00e9es qui contient l\u2019historique de tous les \u00e9changes effectu\u00e9s entre ses utilisateurs depuis sa cr\u00e9ation. Cette base de donn\u00e9es est s\u00e9curis\u00e9e et distribu\u00e9e : elle est partag\u00e9e par ses diff\u00e9rents utilisateurs, sans interm\u00e9diaire, ce qui permet \u00e0 chacun de v\u00e9rifier la validit\u00e9 de la cha\u00eene.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Blockchain priv\u00e9e et publique<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Il existe des blockchains publiques, ouvertes \u00e0 tous, et des blockchains priv\u00e9es, dont l\u2019acc\u00e8s et l\u2019utilisation sont limit\u00e9es \u00e0 un certain nombre d\u2019acteurs. Une blockchain publique peut donc \u00eatre assimil\u00e9e \u00e0 un grand livre comptable public, anonyme et infalsifiable.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Situer la blockchain<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">La premi\u00e8re blockchain est apparue en 2008 avec la monnaie num\u00e9rique bitcoin, d\u00e9velopp\u00e9e par un inconnu se pr\u00e9sentant sous le pseudonyme Satoshi Nakamoto.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Blockchain et bitcoin<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Si le bitcoin est une crypto-monnaie, la Blockchain en est la technologie ou l\u2019architecture sous-jacente. De nombreux acteurs r\u00e9glement\u00e9s par les autorit\u00e9s de march\u00e9s financiers actuellement utilisent la technologie blockchain pour d\u2019autres cas que la monnaie num\u00e9rique.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Comment \u00e7a marche ?<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Toute blockchain publique fonctionne n\u00e9cessairement avec une monnaie ou un token (jeton) programmable. Bitcoin est un exemple de monnaie programmable. Ce token permet de r\u00e9compenser ceux qui s\u00e9curisent, entretiennent et travaillent dans l\u2019int\u00e9r\u00eat de la Blockchain. Les transactions effectu\u00e9es entre les utilisateurs du r\u00e9seau sont regroup\u00e9es par blocs. Chaque bloc est valid\u00e9 par les noeuds du r\u00e9seau, horodat\u00e9 et ajout\u00e9 \u00e0 la cha\u00eene de blocs. La transaction est alors visible pour le r\u00e9cepteur ainsi que l\u2019ensemble du r\u00e9seau.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Comment acheter les crypto-monnaies ?<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Ayez 10$ en bitcoin gratuitement en effectuant un achat de 100$ en crypto-monnaie sur la plateforme&nbsp;<a href=\"https:\/\/www.coinbase.com\/join\/ouazza_w3\" target=\"_blank\" rel=\"noreferrer noopener\">coinbase<\/a>.&nbsp;Vous pouvez aussi acheter vos premiers bitcoins de fa\u00e7on s\u00e9curitaire sur la plateforme s\u00e9curitaire et compl\u00e8te&nbsp;<a href=\"https:\/\/www.binance.com\/en\/register?ref=F3XM8NMN\" target=\"_blank\" rel=\"noreferrer noopener\">Binance<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>D\u00e9finition et explication La blockchain est une technologie de stockage et de transmission d\u2019informations, transparente, s\u00e9curis\u00e9e, et fonctionnant sans organe central de contr\u00f4le (d\u00e9finition de Blockchain France).
