Abstract
Disclosed herein are methods, systems, and apparatus for blockchain-based consensus process having enhanced security. One of the methods includes executing a first smart contract on a first blockchain. Executing the consensus smart contract includes executing code for implementing a consensus process for determining consensus among two or more consensus nodes according to a set of one or more consensus rules. A private key of the consensus smart contract corresponding to the public key is stored in a key management system associated with the second blockchain. The consensus smart contract uses the private key to digitally sign a message requesting a vote, and sends the digitally signed message to the two or more consensus nodes. The public key of the consensus smart contract enables the consensus nodes to validate the message sent from the consensus smart contract. A result of execution of the consensus smart contract are recorded in the first or second blockchain.
