A review on current state of art of a blockchain interoperability

Blockchain technology is one of the highly influential technology nowadays due to its features such as highly secure, immutable data storage. Many blockchain developments are in their infancy because blockchains work in their own silos and are not sufficiently interoperable with each other. Many researches are not sufficient to understand the process of working in interoperability of blockchain area. Therefore, this paper is to provide a sufficient survey on approaches of blockchain, transaction method and type of interoperability. This paper, a proposed flow of the interoperability process for any use case , where blockchain interoperability can be applied. This paper has a comprehensive study and observations for current state of interoperability of blockchains. This paper also provides different platforms which will help for inter operation between crosschain platforms.
