Blockchain Consensus Mechanism for Distributed Energy Transactions

Algorithm 3

Description of the main chain consensus algorithm.

Algorithm: Main Chain Consensus Algorithm

Input: Transaction Collection

Output: New Block

1. The master node sends the packaged transaction set to the blockchain network

2. Broad coast pre-prepare message to consensus node

3. The master node starts the timer

4. When the consensus node receives the pre-preparation message

   Perform verification

   If verification passed

     Send prepare message back to master node

   If the number of messages received by the master node within the timer ≥ 2f

     Then multicast a prepare message

   Else

     End this round of consensus

5. When the consensus node receives the prepare message

   Perform verification

    If verification passed

     Then send a commit message to the master

     When the number of commit messages received by the master node ≥ 2f

      The master node sends a commit collection message to the non-master node

      When the non-master node receives the commit collection message

       Perform verification

       If verification passed

         Then copy the new block content to the local

       End if

     End if

6. End
