Witness

A content-private, accountless quorum timestamper. A federation of independent witness nodes threshold-signs an attestation that a SHA-256 hash existed at a particular time. Clients submit only hashes — never content — and need no account.

Key features

Quorum threshold signing
N-of-M witnesses must co-sign; collusion required to forge.
Instant & free
50–150ms latency, no gas fees.
Content-private
Only SHA-256 hashes are submitted, never the content itself.
Accountless
No accounts, logins, identities, or wallets required.
Dual signature schemes
Ed25519 (fast) or BLS12-381 (aggregated, 96 bytes).
External anchoring
Batches committed to Internet Archive, Trillian, DNS, or Ethereum.
Federation
Independent networks can cross-anchor batches.
Auditable
RFC 9162 Signed Tree Head chains walked by an independent auditor.

How it works

  1. 01 Submit hash Client posts a SHA-256 hash to the gateway.
  2. 02 Batch & route Gateway batches pending hashes and routes them to witnesses.
  3. 03 Threshold sign A quorum of witnesses threshold-signs an attestation.
  4. 04 Return / anchor Attestation returned to client; batches optionally anchored externally.

Quick start

# Assumes a gateway running locally on port 8080
curl -X POST http://localhost:8080/v1/timestamp \
  -H "Content-Type: application/json" \
  -d '{"hash": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"}'

The hash above is the SHA-256 of an empty string — replace it with your own.
