Abstract

The invention provides an oracle machine multi-main-chain cross-chain method and device 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 each first transaction to update a first state tree of a first main chain on the two-layer network; 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, device and storage medium for an oracle machine. 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 an oracle multi-main chain cross-chain method, device and storage medium that prevent double spending on the basis of saving costs. [0004] In the first aspect, the present invention provides an oracle multi-main...
