# CRC-32 > ⚠️ **Experimental — generated with no human supervision** by the daily MCP pipeline to exercise gno tooling. Not audited. See [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md). --- Checksums a few strings and shows that a one-character change moves the result completely. ``` /r/moul/x/daily/crc32demo/v0 → the samples table /r/moul/x/daily/crc32demo/v0:abc → checksum your own text ``` Demo of the [`p/moul/x/daily/crc32`](https://github.com/moul/gno-contracts/tree/main/p/moul/x/daily/crc32/v0) library — no checksum logic lives here. Stateless, so `Render` is deterministic. The table includes `123456789` → `cbf43926`, the standard CRC-32 check value, so the pinned example doubles as a conformance test. The last two rows differ by a single letter and share no hex digits — that avalanche is the property worth seeing.
