EU AI Act readiness · Prepare before 2 August 2026

Proof is verifiable.

Attesto 2.0 is an independent cryptographic proof layer for digital systems. Connect your AI pipeline, compliance infrastructure, operations, or media workflow — and get tamper-evident evidence that any third party can verify without accessing your data.

// The problem

Digital systems that claim to prove themselves cannot be trusted.

[ 01 ]

Logs are claims

When a system stores its own logs, it can also alter them. Trustworthy evidence must exist outside the system it describes.

[ 02 ]

Self-proving architecture

If the same organisation that builds and operates an AI also controls its record, independent verification is not possible.

[ 03 ]

Accountability gaps

Annex IV dossiers, NIS2 incident packets, DORA resilience records — none can be reliably generated from internal logs alone.

[ 01 ]

Digital DNA

Every event, dataset and model version gets a unique cryptographic fingerprint, tied to provenance across every distribution channel.

AI Forensics

Detect synthetic manipulation and retraining drift. Our provenance layer distinguishes human work from algorithmic generation.

Secure Custody

Evidence lives in a privacy-preserving evidence architecture. Raw records stay encrypted in your environment; cryptographic proofs and Merkle roots remain independently verifiable.

// How it works

One proof layer. Independent evidence for everything.

01

Capture

Connect any system via SDK, API, connector, or batch import. Events flow in from AI, operations, media, or compliance systems.

02

Anchor

Each event is hashed, aggregated into a Merkle tree, and anchored to a public chain. Tamper-evident from the moment it lands.

03

Store

Raw records stay in your environment. Only cryptographic roots and metadata leave — never the underlying data.

04

Verify

Any auditor, regulator, or counterparty can independently verify any event without access to your systems.

// The new standard

Trust is mathematics.
Not marketing.

As AI proliferates and regulation tightens, independent proof of what your systems did becomes the most valuable asset you can hold. Attesto 2.0 delivers the infrastructure to make your digital systems independently provable.

  • Independent from the systems it proves
