Ease of practical Byzantine failure tolerant blockchain consensus and node synchronization

摘要

An implementation of the present disclosure includes setting, by a first consensus node, a timer that expires before a timeout of view change; Sending, to the second consensus node, a request for one or more consensus messages lost by the first consensus node in response to the timer expiring; Receiving, from the second consensus node, one or more consensus messages, each digitally signed by the private key of the corresponding consensus node generating each one or more consensus messages; And when f is the maximum number of failed nodes allowed by the blockchain based on the practical Byzantine Fault Tolerance (PBFT), if the number of commit messages included in the received one or more consensus messages is 2f + 1 or more, the transaction And determining that the block is valid.
