BAC (Bivalve) is a public blockchain platform that employs a proprietary consensus algorithm, DPOW – Delegated Proof of Work in English. Miners gain eligibility to mine by staking a certain amount of BAC tokens. Initially, qualified miners enter a pool of candidates, and through each round of voting, a decision-maker is elected; each miner has only one vote per round. The decision-maker communicates with other nodes using the MQTT protocols publish-subscribe model to complete the mining process. The first miner to compute the correct result submits the content to the decision-maker for validation, completing the generation of a new block. Bivalve began development in early 2018 and addresses several prevalent issues on public chains, including transaction performance and security, offering viable solutions.
