A New Sustainable Interchain Design on Transport Layer for Blockchain.

Blockchain is the technology architecture to provide reliable and trustworthy services for the transactions on Internet. Blockchain can remove the middleman or the third parties from the chain of the transactions, which will make the sellers and buyers complete the transactions directly without the help from the other parties. When blockchains are widely used in different areas, a problem is emerging: how to exchange the information among different blockchains. Traditionally, a public blockchain is used to link to the two blockchains which need to exchange their information. Such design can provide a solution to the cross-chain problem. However, there will be three blockchains involved in the data exchange. In this article, a cross-chain protocol is proposed to solve the cross-chain problem. This cross-chain protocol is called Unitary Interchain Network Protocol on Transport Layer (UINP), which supports cross-chain mechanism from the transport-layer. UINP is used in Unitary Blockchain network, and it can give the low latency convenience to blockchain networks that built on the application-layer.
