The well-known code base Github has an open source code suspected of the Huobi Chain. The page shows a total of 105 code submissions. The most recent code submission was an hour ago. The public information shows that the fire currency public chain adopts the Overlord consensus algorithm, and its design goal is to become a BFT consensus algorithm capable of supporting hundreds of consensus nodes, satisfying thousands of transactions per second, and the transaction delay is no more than several seconds. The core idea of Overlord is to decouple transaction ordering and state consensus, so that consensus and execution are completely parallel, which greatly improves the transaction throughput of the entire chain.
