# Provenance Blockchain (HASH) Quantum Readiness Report

> Provenance Blockchain has a QRI score of 3.25/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: Native asset (HASH) and base-layer protocol on Provenance Blockchain mainnet.

Provenance Blockchain (HASH) is a Cosmos SDK-based Layer-1 Proof-of-Stake blockchain purpose-built for financial services and real-world asset tokenization. As of the evaluation date, the project has no post-quantum or hybrid-PQC protection in production. All critical cryptographic layers—spend authorization (secp256k1 user keys), validator consensus authentication (Ed25519 via CometBFT), and state binding (BLS signatures)—rely entirely on quantum-vulnerable classical elliptic-curve cryptography. The project's whitepaper acknowledges quantum risk through a future research item ('Quantum-Resistant Protocol Evolution') but no public cryptographic inventory, quantum threat model, PQC testnet, migration mechanism, or production PQC code exists. Approximately $500M-$970M in market capitalization (~54B HASH circulating) is secured by quantum-vulnerable cryptography. The QRI Score of 3.25 reflects that quantum risk has been acknowledged at a roadmap level (Stage 1) but no meaningful production protection or migration infrastructure exists. The score is capped by the absence of a public cryptographic inventory with quantum threat model (Readiness & Risk Cap: 10) and is ultimately limited by the near-zero Factor Score across all categories.
