Bab: A hash function for content-addressable storage (opens in new tab)

Bab is a family of secure hash functions, heavily inspired by BLAKE3. Bab hashes allow for streaming verification of strings, similar to the BLAKE3-based Bao algorithm. We discuss several optimization techniques that go beyond the Bao specification. Further, unlike BLAKE3 and Bao, Bab digests allow for constant-sized length proofs of their strings.
