Crypto-assets are based on blockchain technology, which ensures the security and transparency of transactions. La blockchain est une technologie de stockage et de transmission d’informations qui fonctionne via un réseau d’ordinateurs. Blockchain is a method of storing and transmitting information through a network of computers. It records all transactions in a decentralised, secure and transparent manner.
In practical terms, a blockchain functions like a large ledger shared across multiple computers. Each transaction is encrypted and added to a block of data, which is then linked to the previous block – forming a chain. This chain is visible to all users and provides a complete and secure history of all transactions made since its creation.
