Contribution

It presents a novel BFT-based gossip protocol with multisig approval, enhancing security and efficiency over existing private ledger solutions.

Findings

Achieves Byzantine fault tolerance in gossip protocols

Supports multisig record approval for security

Operates effectively in partial-synchronous networks

Abstract

ABGP refers to Authenticated Byzantine Gossip Protocol. The ABGP is a partial-synchronous, weak consistent, BFT based consensus algorithm. The algorithm implements the gossip protocol, but with BFT features inside (like multisig record approval). The algorithm has been developed as an alternative to classic private ledger solutions, like Hyperledger.
