How exposure scW\\RX XYG#P

The Quantum Score (0-100) is a deterministic function defined in our published methodology (currently qortrace-method-v0.2, available at /methodology). Lower is worse.

Inputs we look at

For Bitcoin-family chains:

• Address type — P2PK / P2PKH / P2SH / P2WPKH / P2TR (Taproot)
• Pubkey exposure — has the pubkey been broadcast in any prior signature?
• UTXO age — older UTXOs sit on weaker primitives statistically
• Balance at risk — USD value sitting on exposed pubkeys
• Re-use behaviour — number of signatures from the same pubkey

For EVM chains: pubkey is deterministically recoverable from the first transaction, so we instead score on:

• Signature scheme — ECDSA (vulnerable) vs ED25519 (faster Shor break) vs hash-protected schemes
• KMS/HSM exposure — does the wallet sign through an HSM? (lower risk)
• Nonce reuse history — any prior signature reuse?

How factors combine

Each factor produces a sub-score and a weight. The overall score is the weighted geometric mean — meaning a single critical factor can drag the whole score down (we don't let one good metric whitewash a fatal one).

Reproducibility

Every score is stamped with the methodology version it was computed under (e.g. qortrace-method-v0.2). Future bumps don't retroactively re-score older reports — you can always reproduce the original score from the methodology archive at /methodology/v0.2.
