Comment FONCTIONNE LE système Bitcoin ?
Could you please elaborate on how the Bitcoin system functions in simple terms? I'm curious to understand the core mechanics behind its operation. Specifically, how does the decentralized ledger, known as the blockchain, ensure the security and transparency of transactions? Additionally, how does the mining process contribute to the validation of transactions and the issuance of new Bitcoins? Lastly, how does the system ensure that double-spending is prevented, and what role does the Proof of Work consensus mechanism play in this regard? Thank you for your explanation.
