Abstract
A blockchain network include nodes that are configured as time sources. These time-source nodes broadcast respective updates of their local times to all nodes in the blockchain network. Each node computes a summary time value based on the received local time values so that each node uses the same summary time to maintain their respective copies of the blockchain.
