Blockchain Consensus Mechanism for Distributed Energy Transactions

Algorithm 2

Description of primary node election algorithm.

Algorithm: Master Node Election Algorithm

Input: Candidate Node Set.

Output: Master Node Serial Number.

1. Trigger the smart contract to call a random verifiable function to generate a random number for this round of elections

2. The candidate node calls the random verifiable function to generate the random number of this round

   Calculate:

3. If candidate node generates random numbers.

   Broadcast the request verification message.

4. When the consensus node receives the first request verification message

   Timer start

   Verificate

       If signature is incorrect

        Delete this message

   Verificate

       If is incorrect

        Delete this message

   End timer

   Compare < the health score value of all requesting verification nodes >

   Select

5. Broadcast master node serial number

6. End
