Blockchain cross-chain protocol and platform research and development

With the vigorous development of blockchain technology, the application of blockchain networks in various fields is becoming more and more complex. In order to enable information interaction between homogeneous and heterogeneous blockchains to meet business needs in different scenarios, this article propose an improved cross-chain protocol and develop a high-performance cross-chain platform. This article first elaborates and summarizes the current blockchain cross-chain technology, then improves the existing cross-chain protocol based on atomic swaps, develops a set of smart contract templates for the improved protocol, and combines the improved cross-chain protocol. The chain protocol and smart contract are applied to the cross-chain platform, and finally the cross-chain platform is tested. The test results show that the cross-chain platform has high throughput and low latency.
