the validity-rollup that bet on STARKs: transparent, hash-based proofs with no trusted setup and no elliptic curves — post-quantum by construction, scaling by recursion, programmed in Cairo over a small prime field
strictly a scaling system, its lesson still anchors privacy: hash-and-field cryptography is the durable foundation — the same family zheng builds on (hemera Poseidon2 over the Goldilocks field). setups age, ceremonies leak, hashes stay
