Cross-chip interoperation method and system of block chain, storage medium and electronic equipment

Abstract

The invention provides a cross-fragment interoperation method of a block chain, which comprises the following steps: according to a preset on-chain verifier tracking mechanism, sequentially recording verifier sets of fragments from the initial moment to the current moment on the chain; if the first fragment needs to verify the information of the second fragment, the light client on the first chain of the first fragment obtains a block head of the second fragment; according to an on-chain verifier tracking mechanism, the first on-chain light client obtains a verifier set of the second fragment; and according to the verifier set of the second fragment, the first on-chain light client performs validity verification on the block header of the second fragment. The invention further provides a cross-chip interoperation system of the block chain, a storage medium and electronic equipment. Therefore, the cross-chip interoperation can meet the requirements of safety, lightness, universality and modular design at the same time.
