address-only
No public key on record: the only route is to hash candidate keys and compare them with the address (HASH160).

Interval size2722258935367507707706996859454145691648 scalars. Exact BigInt bounds, not a floating estimate.

Snapshot 2 Oct 2026. The reward is the catalog's nominal allocation (N × 0.1 convention from 2023-04-16; earlier spends predate it), not a live balance. A key that matches the address proves the math, not that the coins are still there: check an explorer. Missing fields are omitted, not invented.

Method

Without a catalogued public key the work is sequential HASH160 comparison across the interval, so it grows with the interval size.
