Off-chain payment center routing method and system based on block chain, medium and equipment

Abstract

The invention belongs to the technical field of off-chain payment center routing of a block chain, and discloses an off-chain payment center routing method and system based on a block chain, a mediumand equipment, and the method comprises the steps: each transaction in a payment channel network is segmented into a series of transaction units which are independently routed; a payment center selects an appropriate path to route the segmented transaction units; the payment center maintains a payment rate of a transaction unit in the network to maintain fund balance of the payment channel network; and the payment center performs congestion control on the flow of the transaction units in the network. To solve the problems of low network transaction performance, unbalanced channel fund flow, limited transaction amount of channel capacity and the like of the existing block chain payment channel network, a routing scheme of a payment channel center in the block chain payment channel network and a channel fund flow rate control technology are researched; transaction of a large amount of money can be executed in a low-capacity channel, and high transaction throughput is achieved on the premise that channel balance is not broken.

Description

technical field [0001] The invention belongs to the technical field of blockchain off-chain payment center routing, and in particular relates to a blockchain-based off-chain payment center routing method, system, medium, and equipment. Background technique [0002] At present: With the development of blockchain technology rising to the height of national strategy, blockchain applications are gradually landing on a large scale, and the demand for high-performance blockchain applications is becoming increasingly urgent. Existing work mainly improves the scalability of the blockchain from both on-chain and off-chain aspects. On-chain expansion mainly improves the blockchain in terms of the consensus mechanism, but since the consensus still exists, the delay caused by transaction confirmation is the main reason affecting performance, and the performance bottleneck of the entire network may be limited by the processing performance of a single node. Compared with on-chain expansi...
