Abstract

The invention provides a multi-main-chain cross-chain method, computer equipment and a storage medium, and the method comprises the steps: synchronizing each first transaction which needs to call a transfer 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: judging whether a transfer contract called by the first transaction is a cross-chain transfer contract; if not, executing the first transaction to update a first state tree of a first main chain on the two-layer network; if yes, executing the first transaction to update a first state tree of a first main chain on the two-layer network and a second state tree of a second main chain to be subjected to chain crossing specified by the first transaction; zero-knowledge proof evidences are generated according to the transaction information of the first transactions in sequence, and first proof data are generated according to the first transactions in sequence and the zero-knowledge proof evidences; and sending the first attestation data to the first main chain and other main chains. 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, 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 that prevent double spending on the basis of saving costs. [0004] In the first aspect, the present invention provides a multi-main chain cross-ch...
