eth-verifiable-rpc

Want your RPC node to never lie to you? Now you can check, using the power of storage proofs, right from the comfort of ethers.js.

This implements a verifiable RPC provider. Contract calls are executed in a local EVM, which dynamically loads ALL contract/storage from a remote RPC node, securely, using storage proofs and the eth_getProof API.

It means you can query any contract on Ethereum mainnet, and it is locally loaded and executed securely.

See this specification for a good background on the underlying tech.

Built for Dappnet ENS lookups.

❗️ This library is art, and is only tested for ENS lookups right now. ❗️

Usage.

npm i verifiable-eth-rpc

import { ethers } from "ethers";
import { VerifiedProvider } from "verifiable-eth-rpc";

async function run() {
  const baseProvider = new ethers.providers.InfuraProvider()
  const verifiedProvider = await VerifiedProvider.create(baseProvider)

  const ens = new ethers.Contract(
      "0xd3ddccdd3b25a8a7423b5bee360a42146eb4baf3", // ENS Registry
      [
          "function contenthash(bytes32 node) external view returns (bytes memory)", 
      ],
      verifiedProvider
  )

  const res = await ens.contenthash("0xe6ae31d630cc7a8279c0f1c7cbe6e7064814c47d1785fa2703d9ae511ee2be0c")
  console.log(res)
}

FAQ's.

What's the trust model?

This relies on a provider for the latest Ethereum block. So you can use it to "wrap" Infura with verifiable contract calls, or use it with a consensus layer node (beacon chain client) like Helios.

Can this run in-browser?

Yes.

Is this a light node?

Nope! Even lighter. I chose the term "verifiable RPC" because it conveys better how this works - it's simply a library. It doesn't store any data.

This client does not "track" the blockchain, so doesn't meet the standard of a long-running process to be called a "node".

How does this compare with Helios?

Helios implements this same tech. Honestly, it wasn't ready when I built it. But it seems like they're nearly there lol. Either way, this is useful code.

Roadmap.

If you wanna build something ambitious, here's where you can take this:

[ ] Generate ZK proofs of eth_call lookups based on this library. This would mean users don't run the EVM, they just verify a proof, in O(1) network lookups instead of O(N). This could be done using Kakarot and proving using Giza/Sandstorm.
