simple-otsMerkle-hash your files. Anchor to Bitcoin.

Selective disclosure via OpenTimestamps — no ZKP, no complex crypto, just SHA-256 and a Merkle tree.

Unix-native

Pipe in file paths from find, git ls-files, fd, or any tool. No lock-in, no custom ignore syntax.

Each file generates leaves for every (path-variant × DID) combination. Prove one file without revealing the rest.

Merkle root is stamped via OpenTimestamps to the Bitcoin blockchain. Verification requires no trusted third party.

Same files + same config = same root hash. Always. Rebuild the tree anywhere and verify the proof independently.
