Helios securely connects two levels, unlike the majority of clients, so that users only require to install and execute one piece of software.
The Rust-based Ethereum Light client consensus layer connects to an unsecured RPC (remote procedure call) and utilizes a previously identified beacon chain blockhash to certifiable sync to the most recent block. The Helios execution layer works in conjunction with the authenticated beacon chain blocks and an unsecured execution layer RPC. These parts work together to provide users with a fully trustless RPC without the requirement to operate a complete node.
