A Global Clock Model for the Consortium Blockchains
2019We propose a global clock model to achieve time synchronization for consortium blockchains. Based on the existing consortium blockchain framework, a global clock service node is added. We use the Byzantine fault-tolerant algorithm to ensure the stability of the global clock node services.
