How to Buy Bitcoins Comprendre le bitcoin Comment la méconnaissance générale du Bitcoin pourrait nous priver d’une évolution technologique et économique Contribution écrite par Thibaud Frichet, auteur du blog technophile tfrichet.fr Comprendre le Bitcoin Le principe Pour aborder Bitcoin il existe une vidéo claire, concise et pas très longue éditée par la communauté. Je vous épargne les interviews interminables d’experts et autres économistes… Pensez à activer les sous-titres ainsi que la traduction automatique. Résumons : Avoir des bitcoins Le portefeuille Afin de posséder des bitcoins, vous devez avoir un portefeuille de bitcoins.

My aim in this post is to explain the major ideas behind the Bitcoin protocol in a clear, easily comprehensible way. We’ll start from first principles, build up to a broad theoretical understanding of how the protocol works, and then dig down into the nitty-gritty, examining the raw data in a Bitcoin transaction. Understanding the protocol in this detailed way is hard work. I’ll describe Bitcoin scripting and concepts such as smart contracts in future posts.
