Messages usually include information such as the sender, receiver, amount, and summary, and are propagated and verified within the blockchain network. Each transaction is encrypted and processed by a consensus  algorithm, awaiting confirmation before being added to the blockchain. Once a transaction is successfully confirmed, it will be permanently stored in the blockchain's historical transaction records, ensuring the security and traceability of the transaction. Messages in blockchain are crucial for building trust and achieving decentralization."}]}],"pr":"be0ae1df52c72a681db3f0a08a994f485bf8eeea58d4735b70c9743f857b6306"}
