Multidirectional state channel method and system for blockchain extension, and medium

Abstract

The invention provides a multidirectional state channel method and system for blockchain extension and a medium. The method comprises the following steps: a channel establishment step: establishing amultidirectional payment under-chain channel through cooperation of a channel supervisor S and a plurality of common users; and a channel payment step: in the established multi-direction payment under-chain channel, carrying out transaction is carried out among the common users, and a supervisor S sendings channel state updating information to the plurality of common users according to transactioninformation among the common users. The invention provides an efficient multi-directional state channel scheme supporting parallelism, and effectively solves an application scene that high-frequencybidirectional payment exists among a plurality of users. In the aspect of routing of cross-channel payment, compared with a lightning network and a thunder and lightning network constructed based on abidirectional payment channel, the lightning network and the thunder and lightning network have better performance.

Description

technical field [0001] The present invention relates to the field of offline block chain technology, in particular to a multi-directional state channel method, system and medium for block chain expansion. Background technique [0002] Blockchain is an innovative solution to the multi-party trust problem using distributed ledger technology. Through blockchain technology, a trusted distributed system can be established without relying on any third-party trusted organization. The decentralized nature makes blockchain technology have a wide range of application prospects. The performance of the current blockchain system is seriously insufficient. Taking Bitcoin as an example, since Bitcoin adopts a consensus mechanism based on PoW (Proof of Work), the expected time for the entire network to complete a round of consensus is 10 minutes. Therefore, the Bitcoin system The maximum transaction throughput can only reach 7 transactions per second (assuming the block size is 1MB). The...

Problems solved by technology

However, since each state channel in the Lightning Network and Raiden Network is only related to two users, their network topology is complicated, resulting in difficulty in routing and pathfinding for cross-channel payment, and the algorithm is complex and inefficient

For specific application scenarios, such as high-frequency two-way payments between multiple users, each state channel of the Lightning Network and Raiden Network is only applicable to the value transfer between two users, resulting in most transactions requiring Cross-channel payment or the establishment of a two-way payment channel between any two users will lead to low transaction performance
