📄️ Interoperability Challenge
The blockchain space is evolving towards an ever-growing number of execution shards. L1s, alt-L1s, rollups, app chains, and app rollups all fall under this category. Modular blockchains further complicate the landscape by significantly expanding the design space for blockchains.
📄️ Intro to Polymer
Interoperability for rollups on Ethereum today is both highly fragmented and insecure. Polymer solves this by bringing the strong interoperability foundation set by IBC to Ethereum and its ecosystem of rollups. Our approach to doing so is to put the Cosmos SDK on top of the OP stack and build Ethereum’s first interoperability hub.
