Witness

NextEleven

A provenance prototype that keeps the path from evidence to claims, with signed append-only records.

Overview

Witness separates records into observed, inferred and generated material, so a reviewer can see how a claim came to exist and when its interpretation changed. Written in Rust with signed records and append-only storage.
