Problems solved by technology

At present, this method does not support the anonymity of the payment channel between multiple parties, and when a dispute occurs, the balance status in the payment channel needs to be disclosed to the network, which is also contrary to the original intention of anonymity

Embodiment Construction

[0031] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described here are only used to explain the present invention and not limit the present invention.

[0032] When the inventor was conducting blockchain flux research, he found that the defect of flux optimization in the prior art is that the performance improvement space of the single-chain system is very small, limited by the consensus algorithm of a single chain, network bandwidth and other factors, the existing scheme The research on multi-chain has not been in-depth, and there is no mature and perfect solution. The root cause is that it fails to consider the fact that "transaction data" can be processed in parallel on multiple isomorphic chains at the same time. The main problems include the following two aspects:

Abstract

The invention relates to a parallel transaction processing method based on isomorphic multi-chains, which comprises the following steps: constructing one or more sub-network chains, each sub-network chain having the same block chain framework; dividing a logic transaction to be executed into at least one actual transaction; and distributing the actual transaction to the corresponding subnet chainto carry out parallel transaction processing. Transaction processing mainly comprises one-way asset transfer, Dapp application compatibility and asset aggregation and dispersion. The overall architecture is divided into two parts, namely a client and a block chain platform, the client constructs optimized parallel transactions according to statistical information of the block chain platform, userrequirements are considered comprehensively, and the overall performance of the system is improved; meanwhile, information of a user account is tracked, related states are maintained, and communication under a chain is achieved. Aiming at the performance problem of a single chain, a logic transaction parallel execution algorithm is innovatively provided, the performance optimization bottleneck problem in an original block chain technical architecture is solved, and the flux upper limit of global transaction processing is improved.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method and system for isomorphic multi-chain parallel transaction processing of block chain transaction data. Background technique [0002] As an emerging technology, the blockchain still has many problems to be improved, and the blockchain protocol faces scalability obstacles in the application process. The data of the representative Bitcoin blockchain and the Ethereum blockchain have exceeded 200GB. According to the latest statistics from Etherscan, the total data of the "archive nodes" that fully run all the data of Ethereum has exceeded 2TB. In the current blockchain consensus protocol, the amount of blockchain ledger data will increase over time, especially represented by the public chain in the blockchain. The global ledger data of the blockchain needs to be as much as possible in the public chain. The nodes are fully replicated and stored, which greatly...
