Document Type and Number:
WIPO Patent Application WO/2021/114572
Kind Code:
A1
Abstract:
The present application relates to a blockchain cross-chain data access method and device, an adapter, and a system. According to the technical solution, an adapter is added between a service blockchain and a witness blockchain, a cross-chain initiation event and a cross-chain response event on a local service blockchain are registered to the witness blockchain by using the adapter, cross-chain event querying and push services are provided for other nodes on the local service blockchain, and a related operation on the local service blockchain can be triggered according to a cross-chain event of the witness blockchain. Therefore, a blockchain information island is avoided, data exchange between different blockchains is achieved, cross-chain communication between multi-party services and the sharing of data resources on different blockchains are achieved, and the utilization efficiency of data resources is improved.
