Abstract

The invention provides an intelligent contract clustering parallel block chain implementation method and device, intelligent contracts without dependence relations are distributed into different contract clusters, and each contract cluster has an independent to-be-executed transaction pool, a to-be-executed transaction sequence, a contract cluster state and an independent transaction execution thread to execute transactions. Meanwhile, the block composition is modified to separate and asynchronously perform consensus of the transaction sequence of each contract cluster and consensus of the execution result, so that any long-time-consuming intelligent contract transaction is supported, and intelligent contracts without dependence do not interfere with each other; through a mode of non-waiting or short-waiting transaction execution and parallel execution of transactions belonging to different contract clusters during block generation and verification, the overall time delay of the blockchain protocol stack is greatly shortened, and the concurrent capability and throughput capability of the block chain protocol stack are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of block chain, especially the technical field of block composition, block generation, block verification and intelligent contract transaction execution. Background technique [0002] No matter what consensus algorithm is based on, when a block generation node on a blockchain network generates a block, it will start from the world state achieved by executing the transaction sequence in the previous block, and select a batch of transactions from the waiting transaction pool to be executed The transaction is executed, and then these transactions, the new world state (or its hash value) achieved by executing these transactions, the hash value of the previous block, and other necessary information are generated to generate a new block and the block Send to other nodes on the blockchain network to complete explicit or implicit consensus on the block. [0003] When a block verification node on a blockchai...
