Helios is becoming a multichain light client for Ethereum. Light clients are fundamental to Ethereum scaling. A future with thousands of rollups doesn’t feel far away, and the closer we get, the more critical rollup interoperability will become. 🧵👇

Current proposals to make rollups interoperable — such as Optimism’s Superchain and zkSync’s Elastic Chain — will rely on the existence of secure light clients for rollup operators to validate incoming cross-rollup messages scalably.

Right now, rollup operators need to run full nodes for every chain with which they interoperate. With Helios for L2s, they can run an efficient light client instead.

We’ve started by implementing a light client for the OP Stack based on signed sequencer preconfirmations, meaning Helios can now sync on Optimism, Base, Unichain, World Chain, and anything else within the Superchain ecosystem.

The OP Stack is just the beginning. We’re going to be exploring more robust verification mechanisms, building better tooling for using Helios on the browser, mobile devices, or anywhere else we could imagine someone needing a light client.

We can’t achieve the full scale of crypto’s potential – trustless interactions between billions of people around the world – unless every user and node is able to efficiently verify their data regardless of blockchain, hardware, or internet speed.
