On April 9, the World Economic Forum (WEF) published a white paper on blockchain interoperability, which emphasized the need for interoperability and discussed the degree of interaction between different blockchains in the current state. In the past few years, the integration of blockchain technology has increased in many industries. Therefore, there are hundreds of different blockchain networks in operation around the world. However, in most cases, most of these blockchains cannot communicate with each other in a way that effectively utilizes enterprise solutions. WEF emphasized that the current level of interoperability of blockchain technology and related solutions "is still immature for corporate use."
