# Tidecoin (TDC) Quantum Readiness Report

> Tidecoin has a QRI score of 90.75/100 and is assessed at Stage 4 (Migration Complete / Quantum-Ready) with medium evidence confidence.

Evaluation date: 2026-08-20. Review status: draft. Evaluated scope: Native TDC on the production Tidecoin Layer 1 as of 2026-08-20, covering spend authorization, address and key exposure, proof-of-work consensus, UTXO state integrity, P2P transport, first-party wallet workflows, and native-asset migration. The external wTDC representation on BNB Smart Chain is excluded from native-L1 scoring and treated as an unverified wrapper dependency..

Tidecoin is assessed as a PQ-native production proof-of-work UTXO network for native TDC. Public code, protocol documentation, component repositories, and mainnet artifacts support mandatory Falcon-512 transaction authorization from genesis, no retained classical native-ownership namespace, hash-based state mechanisms, hardened PQ wallet derivation, and no validator-signature authentication layer. Native ECC-to-PQC migration is therefore complete by design. Confidence is Medium because no independent audit was supplied, PQHD and implementation-specific Falcon behavior lack located formal review, and operational assurance documentation is limited. A separate wTDC representation on BNB Smart Chain is outside the native scope and should not be assumed to inherit Tidecoin L1 protection.
