Blockchain Consensus Mechanism for Distributed Energy Transactions

Algorithm 1

Algorithm description of node health score evaluation strategy.

Algorithm: Health Score Evaluation Algorithm

Input (smart contract trigger condition): New node joins and a round of consensus ends.

Output: Node health score value.

1. When new nodes are added

    Trigger health score evaluation smart contract.

2.  If trust base = "A"

      health score =0.6

3.  If trust base = "B"

      health score =0.6

4.  If trust base = "C"

      health score =0.4

5.  End if

6. when a round of consensus ends / a new block is generated.

   Trigger health score evaluation smart contract

7.  If node type = primary

      If the master node sends messages consistently during the consensus phase

        Calculate the master node health score value according to formula (3) :

      If the master node does not send the message in time.

       Calculate the master node health score value according to formula (3):

      If the master node sends messages inconsistently

         Execute the view-change protocol

8.  If node type = candidate

      If candidate nodes send consistent messages

       Calculate the candidate node health score value according to formula (4):

      If the candidate node did not send the message in time

      If the candidate node sends a message different from other nodes

9.  End if

10. End
