PrmiChain is a decentralized distributed sharing system based on blockchain, which is used to form and execute storage contracts end-to-end, negotiate contracts end-to-end on prmiChain, transmit data, verify the integrity and availability of remote data, retrieve data and find content addresses. By optimizing the block spacing, block capacity, and consensus algorithm, theoretically, the available performance of 1000TPS can be achieved. As the core part of the prmiChain platform, prmiChain links all terminals, allowing all network terminal nodes to not only serve as Browsers or Clients, but also serve as network operators and servers....
