Abstract

The invention provides a multi-main-chain cross-chain method based on a multi-main-chain two-layer network state tree, computer equipment and a storage medium, and the method comprises the steps: synchronizing each first transaction which needs to call a first type of contract in a first main chain block in sequence when it is monitored that the first main chain generates the first main chain block; executing the following operations on each first transaction: executing the first transaction to update an asset tree of a second user initiating the first transaction on the two-layer network, a second user root hash of the second user and a two-layer network root; in response to a settlement triggering condition, generating zero-knowledge proof evidences according to the second transaction information of the second transactions in sequence, and generating first proof data according to the second transactions in sequence and the zero-knowledge proof evidences; and sending the first proof data to each main chain. According to the invention, double-blossom is prevented on the basis of saving the cost.

Description

technical field [0001] This application relates to the technical field of blockchain, and specifically relates to a multi-main chain cross-chain method based on a multi-main chain two-layer network state tree, computer equipment and storage media. Background technique [0002] The current cross-chain solution based on the two-layer network is generally one-to-one, and one two-layer network corresponds to one main chain. The applicant hopes to propose a cross-chain solution in which one layer-2 network corresponds to multiple main chains. Compared with the existing technology, the above-mentioned solution is more cost-effective, but there is also the problem of double spending. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a multi-main chain cross-chain method, computer equipment and storage medium based on the multi-main chain two-layer network state tree that prevents double spending on...
