I don’t understand the Cosmos technology, but I love the idea of cross-network interoperation in general. (Hence BIP199 for Hashed Timelocked Contracts - Electric Coin Company, Introducing Project Alchemy - Electric Coin Company, There are three different flavors of "Project Alchemy", BLAKE2b `F` Compression Function Precompile · Issue #152 · ethereum/EIPs · GitHub, etc.)
I’m not sure how to proceed. Maybe someone who understands the Cosmos technology could create some kind of prototype of this and demo it on a hangout-on-air?
