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":"Encryption algorithm: Blockchain uses encryption technology to encrypt blocks and transaction data, ensuring the security and privacy of the data."}]}],"pr":"f01fde9a66cda8bff9df808cea11b96cfc2d31a69f2b6d435186bb190d198730"}
