CONSENSUS NODE CHANGING METHOD AND RELATED APPARATUS BASED ON HONEY BADGER BYZANTINE FAULT TOLERANCE CONSENSUS MECHANISM

摘要

Embodiments of this specification provide a consensus node changing method and apparatus based on a Honey Badger Byzantine Fault Tolerance (BFT) consensus mechanism. The method includes: when receiving a transaction for changing a blockchain's consensus node, executing, by a consensus node of the blockchain, the transaction to trigger a smart contract to update a consensus node configuration list of the blockchain, where the consensus node configuration list includes serial numbers allocated to consensus nodes based on a serial number allocation rule specified by the smart contract; associating, by the consensus node based on serial numbers of consensus nodes in the updated consensus node configuration list, another consensus node of the blockchain with at least two state machines configured in the consensus node.
