TEE Coprocessors in Dstack

Minimal docker file for using the Helios light client to provide a trustworthy view of the blockchain.

You can run this locally - it will output an empty attestation if it's not in a TEE. To run this on Dstack, you can simply copy paste the docker-compose.yml and specify your ETH_RPC_URL parameter.

The provided docker compose uses holesky. Helios currently supports other Eth testnetworks as well as opstack.

This relies on an untrusted RPC, so you need to provide your own ETH_RPC_URL. The free trial at quicknode.com works fine.

Run with:

docker compose build
docker compose run --rm -e ETH_RPC_URL=${ETH_RPC_URL} tapp

Expected output:
