Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a rebalancing strategy execution method for off-chain payment in the blockchain, improve the final effect of the rebalancing strategy, and it can improve the time complexity in a small situation Find out as many effective paths as possible; on the basis of ensuring that the strategy is more fair and reasonable during the execution process, suppress some "malicious nodes" from irregular behavior in the rebalancing strategy, and also maintain the "honest nodes" in the rebalancing strategy. Benefits in the process; at the same time alleviate the problem of fund offset in the blockchain payment channel and improve the usability of the payment channel

Embodiment Construction

[0046] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0047] A rebalancing strategy execution method for off-chain payment in blockchain, characterized in that: the steps of the method are:

[0048] Step S0101: Use a new leader election mechanism for leader election, the election process is as follows Image 6 Shown:

[0049] Step S0201: The node reports the rebalancing demand information such as the node information of both parties in the payment channel, the balance direction and demand amount, the deadline for rebalancing demand reservation, the maximum balanceable amount of the node, and the confirmation signatures of both parties to the leader.

[0050] Step S0202: Participants report the rebalancing demand. When the rebalancing demand meets a certain threshold, the leader announces to all ...

Abstract

The invention relates to a rebalance strategy execution method for off-chain payment in a block chain, which improves the final effect of a rebalance strategy and can find out as many effective pathsas possible under the condition that the time complexity is slightly improved. On the basis of ensuring that the strategy is more fair and reasonable in the execution process, non-standard behaviors of some malicious nodes in the rebalance strategy are inhibited, and the benefits of honest nodes in the rebalance process are also maintained; and meanwhile, the fund offset problem in the blockchainpayment channel is relieved, and the availability of the payment channel is improved.

Description

technical field [0001] The invention belongs to the field of database and information security, relates to related principles and technologies of network flows and payment channels, and particularly relates to a rebalancing strategy execution method for off-chain payment in blockchain. Background technique [0002] In order to solve the capacity problem of the blockchain, there are two main types of mainstream expansion solutions, which are respectively aimed at the two-layer structure of the blockchain transaction system to achieve expansion effects. The expansion plan for the first layer structure is to directly modify the block structure in the blockchain to increase the operational efficiency of the blockchain and achieve faster verification speed. Common methods include directly increasing the block size, adopting a fragmentation mechanism, improving the consensus mechanism, etc. However, such an expansion method will be limited by objective conditions such as hardware...
