Each block contains a certain number of transaction records and is interconnected with other blocks. The transaction information in the block is encrypted and verified to ensure the security and accuracy of the data. Once a block is added to the blockchain, it becomes difficult to tamper with the transaction information within it. The blockchain adopts a decentralized approach, connecting numerous nodes together to form a secure, reliable,  and transparent transaction network."}]}],"pr":"dd4789947ec71b18447594c0f5c4475aa36c18ce3f9dc98f418a30cf91dcf217"}
