the block chain of S7 selects account of leading, the selected account of leading enters into the coordination mode of observer, starts waiting for clock, the unselected account of leading is switched into the mode waiting for receiving trade order, the preferred mode of selecting account of leading is to count the account with maximum interest and trade amount in the group participating cooperative work, the account is used as account of leading, but the selection can be other selection modes, the change of any selection mode does not affect the implementation of the invention;
s8 waiting for the block-making time when the clock enters the block, the account starts processing the parallel transaction, each block has the block-making time, the block-making time is determined by the clock to ensure that each transaction is carried out orderly, when the clock enters the block-making time, the account starts processing the parallel transaction, the processing mode is:
S81, a lead node in the lead account acquires the transaction from the transaction pool, receives the transaction information, is the expression form of the lead account in the block chain, and executes the command of the lead account;
s82 the head pulling nodes are grouped according to the transaction correlation, and after the transactions in the group which are needed by the transaction sequence processing are locked, each group of transactions is sent to the cooperative nodes participating in the cooperative blocking;
after the S83 cooperative nodes receive the transaction, the head-pulling node sends an unlocking instruction of the transaction with correlation to the corresponding cooperative nodes;
s84, processing the cooperative nodes of unrelated transactions, directly processing the transactions without waiting for an unlocking instruction, and starting to process the transactions after the cooperative nodes of related transactions receive the unlocking instruction;
s85, each cooperative node sends the result after the calculation to the head-pulling node;
s86 holding the head node to store the result and recording the contribution of each cooperative node;
s87 sequentially circulating S81-S86 until the transaction is completely processed or when the clock command is met in the transaction processing process of the cooperative node and the period is finished, immediately stopping the transaction and finishing the blocking;
s88 the leading node will gather all the processed transactions and type them into the block, and broadcast the block to the network, finish the parallel processing of local area, wait for the next transaction. The mode of processing the parallel nodes by the account at the front of the account is a multi-node collaborative blocking mode, and the blocking efficiency can be effectively improved by the multi-node collaborative blocking.
S9, after completing the parallel processing of the transaction by leading the account, the processing information is typed into the block and broadcasted to the block chain network 600;
s10, calculating and distributing rewards for the cooperative account, wherein the specific method for calculating and distributing the rewards for the account is as follows:
