Version control you can prove. mkit is a content-addressed version control toolkit written in Rust.
mkit gives you what you expect from Git: commits, refs, branches, and remotes. It also treats signatures and attestations as part of the object model. Every commit carries an Ed25519 signature, and any service can attach witness signatures to it as in-toto v1 Statements in DSSE envelopes.
[!NOTE] Alpha (pre-1.0). The v1 on-disk and wire formats are stable through the 0.x line, pinned by golden vectors. APIs, CLI flags, and unpinned internals may change in any 0.x release. See
CHANGELOG.md.
curl mkit.sh | shThe script downloads the signed release binary for your platform, verifies its cosign signature, and installs mkit into ~/.local/bin.
Linux release archives require glibc 2.39 or newer; see Linux requirements and workarounds.
Other options:
cargo install mkit-cli # crates.io (Rust 1.95+)
bun add @officialunofficial/mkit-wasm # WASM, or: npm i @officialunofficial/mkit-wasm[!WARNING] Do not run
cargo install mkit. That crate name belongs to an unrelated project. The CLI is published asmkit-cli.
mkit supports Linux and macOS. On Windows, run it under WSL. docs/INSTALL.md covers pinned versions, release archives, verification (cosign, SHA256SUMS), and hardware signers.
mkit init # create .mkit/ in the current directory
mkit keygen # generate an Ed25519 signing key
echo hello > hi.txt
mkit add hi.txt
mkit commit -m "first commit"
mkit remote add origin mkit+file:///srv/mkit/my-repo
mkit push origin # first push records origin as the upstream
mkit push # later pushes go to the upstreamThat's your first signed commit. Push rejects non-fast-forward updates unless you pass --force-with-lease or --force.
Attest to the commit, then verify the attestation:
mkit attest --predicate-type https://example.com/sign-off/v1
mkit verify-attest --trust-roots .mkit/attest-trust-roots.tomlverify-attest trusts only keys you register with mkit trust add. SPEC-ATTESTATIONS §6.5 walks through trust roots. The full command reference is in docs/CLI.md. Coming from Git? Read docs/GUIDE-GIT-WORKFLOWS.md.
SPEC-OBJECTS.mkit attest stores in-toto v1 Statements in DSSE envelopes, with the commit hash as the subject. Standard tools such as cosign and in-toto-go can verify them, and one envelope can carry several signatures. See SPEC-ATTESTATIONS.SPEC-KEYSTORE.mkit+file://, mkit+https://, mkit+s3://, mkit+ssh://, or mkit+enc:// (deprecated: no maintained server). mkit never falls back to another transport. See SPEC-TRANSPORT.docs/VERIFY.md.--format=json, and exit codes follow sysexits(3).mkit pulls clearly ahead of Git on large files and their edits, and runs roughly even on everyday operations. Pack creation for 100 files of 1 MiB each:
Pack creation wallclock at 100 files x 1 MiB: mkit finishes in 143 ms versus 1,645 ms for git2 and 2,957 ms for git pack-objects: This Kit feature is not available yet.
The performance page has end-to-end add/commit/push comparisons with Git and the methodology. More microbenchmarks live in benchmarks/charts/. Reproduce them with:
cargo bench -p mkit-benches --bench hashing --bench sign_verify \
--bench object_commit --bench pack_create -- --quick
cargo run -p mkit-benches --bin render-charts| Doc | For |
