About
ProofFrame is a Rust-native data validation engine that checks Arrow-format datasets against strict contracts, catching schema violations, ordering, uniqueness, and statistical rule breaks before data reaches production. It produces deterministic fingerprints and reviewable evidence records so validation results can be verified rather than just trusted, and version 0.7.1 adds eleven new rule types along with a WebAssembly build that runs entirely in the browser.
Why it made the leaderboard
Compiles strict Arrow data contracts that catch things a schema check misses (ordering, ledger balance, category drift) and produces a deterministic, verifiable fingerprint, with a WASM build that checks CSVs entirely in-browser.
