First, nodes on each chain perform preprocessing on the transactions and reach a consensus. Then, during the transaction  confirmation process, nodes follow the two-phase commit protocol, dividing the process into two stages: pre-commit and formal commit. ↵↵The pre-commit stage validates the correctness of the transaction, and after reaching a consensus among all nodes, it proceeds to the formal commit stage. If an error occurs during the pre-commit stage, the transaction will be rolled back, ensuring the atomicity of cross-chain transactions. Meanwhile, the use of distributed consensus algorithms (such as PBFT) also ensures the security and stability of the entire system."}]}],"pr":"0c8fced8f383771242604af805bcd912fb65940c56e108569ac6c561829015c8"}
