Three-Stage Cross-Chain Protocol Based on Notary Group

With the continuous development of blockchain technology and economy, applications have been well developed in multiple key areas. The demand for interoperability between different blockchains is also increasing. Cross-chain protocol has become a major approach to solve cross-chain problems by defining series processes standards. In response long transaction time, high costs, degree centralization most protocols, this paper proposes three-stage based on notary groups verification groups. Without increasing costs problem mechanism solved, realizing secure fast interaction blockchains. Experimental results show that as malicious nodes group do not exceed one-third, can effectively ensure security transactions problem.
