Ethereum researchers outline five paths to formally verify clients and shrink trust base
- —TCB covers components and assumptions accepted as trusted without verification
- —Pure modules (cryptography, SSZ, fork choice) are suited to formal verification
- —Impure modules (networking, I/O) should be designed so their outputs are not trusted
- —Five paths: Rust-to-Lean4 conversion, Lean4-to-C extraction, Lean4 client, RISC-V, verified compiler
Why it matters: Shrinking the TCB would reduce the attack surface of Ethereum clients, though this remains research rather than a shipped solution.
