Problems solved by technology

[0018] (3) Due to the characteristics of the channel network, the network may be sparse, and there are few opportunities to complete transactions through direct connections. Therefore, the method of simply isolating Type II nodes is not suitable, and these Type II nodes need to be fully utilized;

Embodiment Construction

[0062] With reference to the accompanying drawings, the specific implementation of the present invention will be further described in detail through the description of the embodiments to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0063] To construct a dynamic evolutionary game model based on a channel network, three basic elements of game analysis need to be considered: participants, strategy space and profit matrix.

[0064] Participants in the game are composed of two different sets of nodes: one is a set of nodes composed of type I nodes, which can obtain revenue by forwarding a transaction; the other is a set of nodes composed of type II nodes, which can be Gain revenue by launching attacks or forwarding transactions.

[0065] For type I nodes, there are three strategies: cooperation, non-cooperation and defense. The strategy space of type I nodes is recorded a...

Abstract

The invention discloses a channel network steady-state evolutionary game method in a blockchain environment. Based on finite rationality and a replication dynamic mechanism of a biological evolution process, node transactions in the channel network are modeled into a dynamic evolutionary game model, the model designs a channel network dynamic defense mechanism based on evolutionary game, the mechanism adds a defense strategy to a strategy space of an I-type node, and under the condition of considering the attack cost and success rate of the II-type node under the condition of deploying the defense strategy, and the defense mechanism can help the I-type node to resist attack behaviors of the II-type node at a certain probability. The nodes of the model have limited and rational evolutionarylearning capability, and can dynamically adjust respective strategies to achieve effective defense according to different attack strategies of attackers.

Description

Technical field [0001] The present invention belongs to the field of blockchain technology. More specifically, the present invention relates to a steady-state evolutionary game method of a channel network in a blockchain environment. Background technique [0002] The security of blockchain-based cryptocurrencies (such as Bitcoin and Ethereum) comes in part from the extensive replication of block data, which requires limited scalability. One of the main ways to increase the scale of cryptocurrency is to focus on moving transactions from the blockchain to the off-chain through the use of peer-to-peer payment channels. Traders can perform a large number of transaction transfers through the channel and finally settle the net income on the blockchain. , In order to reduce the delay of transaction confirmation. Although off-chain payments based on the channel network are fast, if one party withdraws from the transaction and closes the channel, both parties will need to submit each ope...
