Cryptographic trust

Three layers.
One verified identity.

Verification on TETA+PI is not a manual review. It is cryptographic proof anchored in official registries, content signatures, and Bitcoin timestamps.

🏛️
Layer 1

Registry verification

We query official government and industry registries in real time to confirm that an entity exists, is active, and matches the claimed identity. No self-declaration.

Layer 2

C2PA content signing

The Coalition for Content Provenance and Authenticity (C2PA) standard allows verified entities to cryptographically sign their content — articles, images, videos, product data. Any agent can verify that content came from a TETA+PI-attested entity.

c2pa:manifest → issuer: TetaPi GmbH
entity: GreenFarm GmbH · verified: true
signed: 2026-06-29T14:32:11Z
Layer 3

Bitcoin timestamping

A hash of the verification record is committed to the Bitcoin blockchain. This creates an immutable, trustless timestamp — no party (including TetaPi GmbH) can retroactively alter or revoke a verification without it being detectable.
