SG Consensus Algorithm Implementation

Current implementation note (October 2026): The message sequence below is an earlier protocol illustration, not a full specification of current validator admission or quorum. The current SuperGenius code has a genesis-seeded TrustedPeerRegistry, quorum-controlled membership updates, and ValidatorRegistry logic. General participation in compute jobs must not be confused with the validator/signer set. Consult the pinned source for current configuration and security assumptions. See Platform Status.

• SG Consensus algorithm is based on GOSSIP protocol.
• System uses libp2p library for P2P Gossip messaging.

Gossip Message Types

• BLOCK ANNOUNCE
• VERIFICATION
• TRANSACTIONS
• STATUS
• BLOCK REQUEST

Consensus protocol uses VERIFICATION gossip message for consensus process. There are two different types of VERIFICATION message

1. VOTE message
2. FIN message

There are three different types of Vote Messages\ \ Primary Propose\ Primary node broadcasts Primary Propose message to all nodes to validate a transaction.\ Pre Vote\ Nodes after receiving Primary Propose send Pre-Vote message (initial vote) to all other nodes.\ Pre Commit\ Nodes after receiving pre-votes from other nodes sends stronger commitment using pre-commit vote.
