Sur l’utilisation de la modélisation et de la simulation basées agents pour étudier les systèmes de chaînes de blocs

International audienceBitcoin is the core of decentralized cryptocurrency systems. The underlying data structure of Bitcoin is called the blockchain in which transactions of digital coins between accounts are batched in so-called blocks, where each block is appended to the last one in a cryptographic way to make the malicious/accidental change of blocks content very hard. Participants following this protocol can create together a distributed, economical, social and technical system where anyone can join/leave and perform transactions in-between without neither needing to trust each other nor having a trusted third party. It is a very attractive technology since it maintains a public, immutable and ordered log of transactions which guarantees an auditable ledger accessible by anyone
