Most agree that a multi-chain future is near, and highly probable: but beyond basic interoperability between blockchains, this future is rather vague. What forms will decentralized applications take?
In this post, we’ll dive deep into the problems that arise from the imminent multi-chain future, the current state of interoperability affairs, and how dapps in this ecosystem are likely to develop.
## Starting from Scratch
Why is interoperability important?
The multi-chain world is here, and it’s one of the most pivotal upgrades in crypto’s short history. Born out of a need to scale crypto to millions of users, a large set of new blockchains launched offering developers a wider array of design choices to create more custom user experiences. Tradeoffs between security, speed, and scalability are inherent in decentralized application design and these decisions naturally create fragmentation.
