Abstract

The present invention provides a block chain implementation method and device for smart contract clustering and parallelism, assigning smart contracts without dependencies into different contract clusters, each contract cluster has an independent transaction pool to be executed, and a transaction sequence to be executed , contract cluster status, and an independent transaction execution thread to execute transactions. At the same time, the block composition is modified to separate the consensus of the transaction sequence of each contract cluster from the consensus of the execution result and proceed asynchronously. While supporting arbitrarily long and time-consuming smart contract transactions and smart contracts without dependencies without interfering with each other, Through block generation and verification of transaction execution without waiting or short waiting and parallel execution of transactions belonging to different contract clusters, the overall delay of the blockchain protocol stack is greatly shortened, and the concurrency capability of the blockchain protocol stack is greatly improved. and throughput capacity.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to the technical field of block composition, block generation, block verification and smart contract transaction execution. Background technique [0002] No matter what consensus algorithm is based on, when a block generating node on a blockchain network generates a block, it will start from the world state reached by executing the transaction sequence in the previous block, and select a batch of pending transactions from the waiting transaction pool. Transactions are executed, then these transactions, the new state of the world (or its hash) resulting from the execution of those transactions, the hash of the previous block, and other necessary information, generate a new block and convert the block It is sent to other nodes on the blockchain network to achieve explicit or implicit consensus on the block. [0003] When a block verification node on a blockchain network r...
