Analyzing Asynchronous Binary Byzantine Agreement (ABBA) Consensus on SKALE Blockchain
Asynchronous Binary Byzantine Agreement (ABBA) Consensus aims to produce blocks at any condition without error. It is the most efficient consensus created by Achour Mostéfaoui. Bitcoin blockchain has never faced any failure since ten years of its launch. In future, we may face more failures like this as a result of single-point failure. In this case, the Bitcoin blockchain is the first generation of the blockchain so it has some limitations and flaws; for example, PoW consensus uses a massive amount of energy and computational power.
