## プロジェクトの歴史と使われ方

Bao is a Rust implementation of BLAKE3 verified streaming. It provides both a library crate and the bao command-line utility for encoding, decoding, hashing, and verifying byte streams with tree-hash-based random access.

### プロジェクトの歴史

The official Git history begins in November 2016 with preliminary verified-streaming work, and the 0.1.0 tag followed in October 2017. The README explains that Bao's original motivation was secure streaming of large attachments where a recipient knows a root hash but does not want to download the whole file before verification.

The current spec documents an important historical shift: earlier Bao versions used BLAKE2 in a custom tree hashing mode, then the BLAKE3 project evolved out of that tree mode. After BLAKE3 was published separately, Bao was rebased and narrowed to focus on verified streaming.

### 採用の歴史

Bao is niche compared with general-purpose checksum tools, but it is packaged where Rust cryptography and content-addressed tooling users might need it. The supplied package facts list Homebrew and Nix packaging, and the README points Rust users to the bao_bin crate on crates.io for the CLI.

### 使われ方

The README demonstrates bao encode, bao hash, bao decode, slice extraction, decode-slice, and outboard mode. The main workflow is to store or transmit encoded data plus a known BLAKE3 hash, then verify bytes as they are streamed or randomly sliced.

The project cautions that Bao is beta cryptography software and has not been formally audited, an important usage note for security-sensitive deployments.

### パッケージ好きにとっての重要性

Bao matters to package nerds less as a mass-market CLI and more as an artifact of the BLAKE3 ecosystem. It shows how tree hashes can support verified partial reads, outboard metadata, and streaming-friendly integrity checks.

It is also notable packaging-wise because the command is provided by the bao_bin Rust crate while the repository also contains the bao library crate, so package definitions need to select the binary crate behavior rather than assuming a single-crate CLI.

### タイムライン

- 2016: Public Git history begins with preliminary verified-streaming work.
- 2017: 0.1.0 is tagged after Cargo metadata is added.
- 2018: Early 0.x tags iterate on the Rust crate and encoding format.
- 2020s: Bao is rebased around BLAKE3 after earlier versions used BLAKE2 in a custom tree mode.
- 2025: 0.13.1 is tagged as a recent maintenance release.

### Related projects

- Bao is directly related to BLAKE3, the BLAKE3 specification, b3sum-style hashing, Rust crates.io packaging, and content-addressed storage or secure streaming systems that need partial verification.
