Preserve the exact artifact state behind an analysis, review, or archive.
Local-first research provenance
Evidence that travels
with the work.
Create a verifiable receipt for a research artifact without uploading the source file.
Who it is for
Research changes hands before it becomes a result.
Attestome keeps an artifact's integrity evidence attached to the handoff—from the person who created it to the person who needs to check it again.
Return instrument outputs with portable evidence instead of another opaque portal.
Verify independently without needing the creator's software account or file history.
What it does
Turn a local file into portable evidence.
The file stays in this browser. Attestome records a digest and carefully limited context, then gives you a receipt another person can verify.
Your verifiable receipt appears here.
Choose a file for byte-level evidence or continue with an explicitly labeled metadata-only record.

Receipt checksum
—Scope: this receipt records a digest and a creator declaration. It does not prove scientific validity, authorship, chronology, ownership, or regulatory compliance.
How it works
One repeatable path from artifact to independent check.
The workflow is intentionally small. No account, upload, or automatic wallet request sits between the file and its evidence.
Local workflowNo receipt yet
01 / 05
Choose the artifact you want to hand off.
The browser reads the selected bytes only long enough to calculate a digest. Attestome does not upload or retain the source file.
- Input
- Local file
- Output
- In-memory bytes
Independent verification
Import the receipt. Recompute the evidence.
A collaborator can test the exported receipt and, for file-backed evidence, compare the source bytes again.

Why it is different
Integrity evidence without a black box.
Attestome makes a narrow promise and makes it testable. It records what was presented, not what the research means.
The artifact state
- File digest and byte size
- Redacted research context
- A portable receipt digest
The evidence again
- Whether receipt data changed
- Whether source bytes still match
- Whether the format is deterministic
The science is true
- Authorship or trusted chronology
- Scientific validity or ownership
- Clinical or regulatory compliance
Local by default. Portable by design.
Wallet context is optional and read-only. Signing, payment, and on-chain publication remain outside this release.
See the optional evidence layer ↗Where it goes next
A practical path from local receipts to shared research infrastructure.
The current product stays useful on its own. Future capabilities will add assurance only when their governance and security are ready.
Portable local receipts
Local hashing, redaction-aware context, export, import, tamper detection, and source-file comparison.
Linked research history
Related artifact versions, creator-signed claims, and shared verification tooling with explicit trust boundaries.
Institutional connections
Repository adapters, public registries, and optional anchors—without turning the receipt into a scientific verdict.
How to participate
