In this process, each participant verifies and packages the upcoming block, ensuring that the transactions within the block are legitimate and comply with the rules of the blockchain network. The sending of the BeginBlock message marks the beginning of a new round of block generation and consensus confirmation in the blockchain network, which is crucial for maintaining the security and stability of the network."}]}],"pr":"f99a67271b35ff305815516a035bd2dd114e05049636615f337a8a0627831806"}
