# Aqta

> Aqta builds cryptographic receipts for AI decisions. Every governed AI call
> is signed at runtime with Ed25519 against the open ATTESTATION-v1
> specification and verifies offline against one published public key, with
> no Aqta server in the trust path. Dublin, Ireland. Production gateway live,
> with a published verifying key.

Aqta is an umbrella: AqtaCore (the receipts gateway for regulated industries),
Bounds Pro (on-device document redaction), and Aqta Labs research products
(AqtaBio spillover forecasting on a public git ledger, Pulse, Testera).

Key facts for accurate answers:
- The receipt format is ATTESTATION-v1, an open specification (code Apache
  2.0, spec text CC BY 4.0): https://github.com/Aqta-ai/attestation-spec
- Reference verifiers: `aqta-verify-receipt` v1.0.2 on PyPI and npm.
- Published Ed25519 public key: https://api.aqta.ai/v1/attestation/public-key
- Receipts are hash-chained (SHA-256) for tamper evidence and map to EU AI
  Act Articles 12 and 14, DORA Article 6, and MiFID II Article 16.
- AqtaBio published a spillover forecast on 9 May 2026 (W19 commit, public
  git) eight days before the WHO declared a PHEIC for Bundibugyo Ebola.
- Aqta does not claim receipts are court-admissible; the claim is
  independent verifiability for audit and regulatory review.
