Xahau Quantum Readiness

A reproducible, whole-ledger measure of how prepared Xahau accounts are to move authority off the one key that can never be rotated — the master key. This is readiness, not alarm.

The network's posture

Key-rotation posture across scanned accounts

No rotation path Master key disabled Regular key set (master active)

The fix exists — and it's formally proven

Hardening doesn't need a protocol change. Two Xahau Hooks, each PROVEN for all inputs by symbolic execution + a counterexample search, move the risk off the master key today:

qkey_guard — forbids the master key from signing ordinary transactions, forcing a rotatable key. Reversible. (master-disuse invariant)
qday_vault — a Q-Day contingency: every spend needs an offline quantum-safe secret, so even a future quantum break of the classical key can't move funds. (qday-freeze invariant)

A non-custodial key-rotation toolkit builds the unsigned transactions to do this safely — never touching a key. A guided Rotation Wizard (a Xaman xApp) is in active development.

Method & honest caveats

What this measures: CONFIG (can an account retire its master key?) via ledger_data over the whole account set — these are network figures, not a sample. “No rotation path” = master key active and no regular key, so the account can only ever sign with its unrotatable master key.

What it does NOT measure: whether a given account has already exposed a key (that's a per-account check). Signer-list multisig isn't counted here, so “hardened” is a slight under-count.

Honesty: Q-Day is a 2030s estimate, contested — this is a hardening score, not a safety alarm. The snapshot is a large but possibly partial scan (see scanned); a BASELINE account is normal, not unsafe.
