## Description

Jordi Baylina will explain how is possible to bridge assets and messages between chains in a few seconds. I will talk about the composability of the chains. On the technical side, I will highlight the importance of zk-proof recursivity to aggregate the proof of many blocks of different chains and consolidate them in a single proof in the Ethereum mainnet.
