Problems solved by technology

[0003] With the development of blockchain technology and the continuous birth of new chains, the demand for data interaction between chains continues to increase. However, since blockchains are relatively closed systems, different blockchain protocols are incompatible and are in the relatively fragmented state
The difficulty of collaboration between different blockchains greatly limits the development of blockchain applications

Abstract

The invention relates to a blockchain cross-chain data access method, device, adapter and system. According to the technical scheme, the adapter is added between a service block chain and a witness block chain; and the adapter registers a cross-chain initiating event and a cross-chain response event on a local service block chain to a witness block chain, provides cross-chain event query and pushservices for other nodes on the local service block chain, and can trigger related operations on the local service block chain according to the cross-chain event of the witness block chain. Therefore,a block chain information island phenomenon is avoided, data interaction between different block chains, cross-chain communication between multi-party services and sharing of data resources on the different block chains are realized, and the utilization efficiency of the data resources is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a blockchain cross-chain data access method, device, adapter and system. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, traceability throughout the process, traceability, collective maintenance, and openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for the creation of trust in the blockchain. The rich application scenarios of the blockchain are basically based on the fact that the blockchain can solve the problem of information asymmetry and realize collaborative trust and concerted action among multiple subje...
