SimpleChain is a Simple to use blockchain, a digital reform of the blockchain infrastructure . SimpleChain does not exist pre-digging, no private equity, pure PoW main-chain;SimpleChain is the public blockchain that has the design concept of one main-chain with multiple sub-chain, applying PoW which is the only distributed consensus mechanism practiced through time and scale combining open consensus algorithm and publicly available consensus algorithm to guarantee the security of ledger. By designing the multi-layer distributed value network, SimpleChain can support the deployment and extension of public blockchain in multiple business scenarios. Sub-chain can choose their own consensus algorithm which is suitable for their scenarios according to business requirement, and the two-way anchoring between the cross-chain node and the main chain further forms the cross-chain transactions with other sub-chain. It can satisfy the performance of thousands of TPS, and obtain the eventual consistency provided by the main chain at the same time.Telegram | MediumWhitepaper
