This puzzle needs about 255.5 search steps — below the line (269).

Every puzzle below the line has been found.

Model: kangaroo. The public key has been on chain since 2019, so the square-root shortcut applies: about 2 × 2(N−1)/2 group operations.

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.
