Transaction processing system and method for backbone-free multi-fragment blockchain

Abstract

The invention provides a transaction processing system for a backbone-free multi-fragment blockchain. The system: comprises a client which is used for creating and managing local account set information, periodically obtaining the latest state of the whole network of a local account set, generating a transaction containing source fragment information and target fragment information based on transaction demands between accounts, and sending the transaction to a fragment corresponding to the transaction for execution; and a blockchain platform which is used for processing and receiving and executing transactions of account state changes on the blockchain and comprises a plurality of fragments, wherein each fragment comprises all nodes running the same blockchain protocol, and each fragment changes the state of the corresponding account on the fragment based on the received transaction and packages the transaction corresponding to the transaction into the new block to complete execution of the transaction. The block structure is improved, a three-stage processing mechanism is adopted, the problem that the execution sequence of cross-chip transactions is unpredictable and the expansibility problem of the blockchain are solved, smaller storage calculation overhead is achieved, the node operation burden is relieved, and flux is improved.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to the field of block chain application expansion, and more specifically, to a transaction processing system and method for multi-shard block chains without a main chain. Background technique [0002] As an emerging technology, the blockchain still has many problems to be improved, especially the scalability obstacles faced by the blockchain protocol in the application process. The blockchain technology represented by Bitcoin generally adopts the unified consensus process of the whole network, and the global ledger data is copied and shared by the whole network. This design stems from its original design goal only for verification and use in a small technical community. The simplicity and robustness of the blockchain protocol are the initial design premise of the blockchain technology, and it does not consider the promotion to a wider range of high-concurrency Internet applicatio...

Problems solved by technology

Therefore, most of the existing research programs adopt the multi-chain parallel mode, but the research on the multi-chain parallel mode in the existing programs has not been in-depth. The current multi-chain program parallel program is still immature, and there are still various weaknesses. The bottleneck of overall expansion of the chain, obstacles to application expansion, etc.
