AttestLayer Public Registry

Public append-only transparency log for AttestLayer-issued PASS attestations. Every issued kit is recorded here with a signed checkpoint, Merkle inclusion proof, and timestamp. Read-only and unauthenticated — anyone can verify independently.

For non-technical reviewers

This page is the public log of every verification kit AttestLayer has ever issued. Each entry is signed, timestamped, and included in a Merkle tree so anyone can prove a kit existed at a given time without trusting AttestLayer. You do not need to use this page to verify a kit — the Verify page does that for you.

Current trust model

The registry is live and publicly readable. Checkpoints are currently self-issued by AttestLayer and signed with the registry key (registry.jwks.json). Receipts inside verification kits are signed with a separate issuer key (issuer.jwks.json). External witnessing and external anchoring should only be described when active.

Common Actions

Verify a kit: verify.attestlayer.com — upload kit.zip to verify manifest + receipt (how to verify in 60s)
Fetch JWKS: /v1/jwks/registry.jwks.json — checkpoint-signing public keys (for receipt verification use issuer.jwks.json)
Latest checkpoint: /v1/checkpoints/latest.json — current signed tree head
Inclusion proof: GET /v1/proofs/inclusion?leaf_hash=X — prove a leaf exists in the tree

Registry Status

Public registry online

The public transparency log is live and accepting entries. Checkpoint data will populate here as PASS attestations are issued and logged. Use the sample kit or verification links below to explore the registry structure.

Sample entry

Every PASS attestation produces a log entry like this:

{
  "leaf_hash": "cf4fe8a7e4b75f2f5142741443dbebcdc78f2e657847b9a6b73a6ff697035590",
  "receipt_id": "samplekit00000001",
  "manifest_sha256": "a7a963af8e2341e6888d2699aeb6c29a48043ef4f299b2dd87a9a607a86fb02d",
  "issued_at": "2026-06-01T00:00:00Z",
  "receipt_kid": "8adefa300a1059bc"
}

This is the sample kit entry. Real entries follow the same structure.
