The world’s largest companies are actively developing their own blockchain projects. With the spread of distributed ledger technology, the issue of interoperability, i.e. the active interaction of different decentralized systems, is becoming increasingly relevant.

Let’s start with the concept itself. Interoperability is about connecting different blockchains. Multi-chains can connect networks at many different levels – they allow not only blockchains but also Layer 2 solutions that are deployed on top of underlying blockchains. Beyond that, they can connect L2 blockchains as well.

I like the analogy with the World Wide Web and local area networks. If you remember, you may not have had Internet access in the past, but you could replace it with LAN networks. They could exist inside one city, and all accessible sites were only in the loop of this local network. At the same LAN themselves were not connected with each other. In fact, Moscow and St. Petersburg had two different Internet, and each had its own set of services.

This is very similar to the current situation with blockchains – they are not connected to each other, and each has its own set of decentralized applications. At the same time, these blockchains do not communicate with each other – this problem is solved by multichains.
