Each block contains some transaction data, distributed across many computers worldwide, known as nodes. The operating principle of blockchain is based on a consensus mechanism, where nodes must reach a unanimous agreement to validate and  record new transactions. Once a transaction is added to the blockchain, it cannot be changed, ensuring high security and transparency. Blockchain technology uses a distributed node consensus algorithm to generate and update data, utilizing cryptography to guarantee the security of data transmission and access, and employing smart contracts to facilitate secure and efficient transactions."}]}],"pr":"390b7d074cca7828620aefebff9bb11e9054cf83651c8529af93a9ce63b77c0b"}
