When we launched EthSystems we said each use case needs its own system, designed, specified, and hardened properly, and that someone has to do that work. Our specs site is now public: specs.ethsystems.org Starting small: a shielded pool for confidential payments, an attestation-gated profile of it, and the process behind both. Each spec states what the protocol does, what it assumes, and what it guarantees. This means engineers, auditors, and regulators can work from the same document.
