![]() Blockchain, which has become a hot research topic in recent years, may be one of the solutions. But some problems remain in IoT before it can be applied in a large scale. Many people regard the Internet of Things as the next-generation network structure, which means all the embedded devices can communicate with each other directly. With the development of technology, the network structure has changed a lot. Experiments have been carried out, and shown that the cross-chain blockchain network structure we provided is feasible to meet the requirement of large-scale distributed IoT applications. After investigation of the current blockchain consensus algorithm and blockchain architecture, we propose: (1) an improved blockchain consensus algorithm, which is implemented based on the mortgage model instead of probability model (2) a cross-chain protocol with transverse expansion capacity, which would support the message transmission among chains (3) a high-performance cross-chain blockchain network structure, which could handle more than 1000 transactions per second per chain by verification. This paper focuses on to implement a high-performance blockchain platform. However, currently, the transaction speed of blockchain is still a disadvantage compared to traditional transaction methods. ![]() ![]() However, some problems remain in IoT before it can be applied in a large scale. ![]()
