PlatONE is a financial-grade blockchain platform. It has involved in areas like payment and settlement, AI, IoT, healthcare, credit system,advertising and key management. PlatONE supports pluggable different consensus protocol which includes Concurrent BFT and Optimized BFT. VRF and probability distribution are used to randomly select consensus nodes, which can balance decentralization and scalability. Concurrent BFT: block generation and block verification are performed in parallel, which greatly improves the rate of block generation while ensuring BFT 1/3 fault tolerance. In the test network, it takes 1 second to reach consensus and generate block. Optimized BFT: Introducing unlocking mechanism to solve the consensus deadlock issue and the chain can support more than 100 consensus nodes. In the test network, it takes 1 second to reach consensus and generate block.
