Blockchain
Basics
Ce que ça veut dire
A decentralized, distributed digital ledger that records transactions across many computers. Each "block" contains transaction data, and blocks are linked chronologically in a "chain". Blockchains are the technology underneath most cryptocurrencies.
Exemple
Bitcoin's blockchain records every Bitcoin transaction since 2009, and is maintained by a global network of computers rather than a central authority.
L'erreur des débutants
Beginners think "Bitcoin = blockchain". Blockchain is the technology; Bitcoin is the first application of that technology. There are many other blockchains beyond Bitcoin.
