It is a digital ledger that records transactions across multiple computers, using cryptography to ensure the security and integrity of the data. Each computer in the network maintains a copy of the ledger, and new transactions are verified and added to the ledger by the participating nodes. This creates a distributed, tamper-proof system that eliminates the need for a central authority or intermediary.","a":"Decentralization: Blockchain adopts a distributed network architecture, does not depend on centralized servers or  institutions, and can reduce the risk of single-point failure, improving system stability and security."}]}],"pr":"5dd7f6c51056eb6a020817b21465a3e6fa10d7802ca42f28c5cdd1437dd54b1b"}
