The industry blockchain: multiple pre -selected nodes are specified within a group as the bookkeeper. The generation of each block is determined by all pre -selected nodes. (The pre -selected node participates in the consensus process), other access nodes can participate in the transaction, but the questioning process (essentially the custody of the accounting, but only becoming a distributed bookkeep The ledger has become the main risk point of the blockchain), and anyone else can make a limited query through the API opened by the blockchain.
