AI accountability,
solved.
AI accountability isn't just about logging what happened. It's about being able to prove it, to anyone, forever.
Who it's for
Built for
Trust for everyone.
AI systems are now making critical decisions at scale and regulators are starting to mandate proof of what happened.
Where verification and proof is needed, conventional audit mechanisms rely on centralized databases and log files that are vulnerable to tampering, selective disclosure, and loss over time.
Sarek solves this by making your AI data immutable, secured and verifiable by anyone, while not disclosing any sensitive data.
Whether you're shipping an AI product or running an AI-powered organization, Sarek provides future-ready tools to give AI its own accountability.
One line of code.
Drop it into your existing setup. Everything else is automatic.
Stamped, anchored, secured.
Every AI call cryptographically sealed and immutable.
Verifiable by anyone.
Mathematically provable. That it happened, when, and by whom.
Audit-ready. Always.
Auditors can always verify directly. No access requests, no intermediaries.
EU AI Act
EU AI Act
Deadline: August 2026.
The EU AI Act is the world's first comprehensive AI regulation. If your organization uses AI to make decisions that affect people, you are required by law to document, log, and prove what your AI systems did and why.
Up to €30M fine
Or 6% of global annual turnover — maximum penalty for non-compliance with the EU AI Act.
Article 12 — Logging
High-risk AI systems must automatically record events over their entire lifetime. Sarek is built for this.
How Sarek supports EU AI Act today
Every AI decision automatically logged, secured and provable.
GDPR by design.
How we support the future
EU regulations consistently evolve from principles to technical specifications. We anticipate that 2026–2029 is when cryptographic proofs for AI becomes a legal requirement. Sarek is built for that future, today.
Developers
Drop in.
Walk away.
Simple by default.
With Sarek, every AI decision your application makes is automatically logged, signed, and anchored on-chain. Ready for audits, regulators, and clients. Your code stays exactly as it is.
Deeper control when you need it.
Manage reports, proofs, and verification via the CLI. Configure agents with cryptographic identity and role. Listen for on-chain confirmation callbacks. And more.
Privacy by design, not by policy.
Sarek never sees sensitive data. Every call is monitored locally. Only the signed cryptographic fingerprint is sent, verifiable on-chain.

The Sarek Core
trust layer.
Sarek Core gives your data a trust layer with six levels of trust.
1.
Tamper-proof
Every point of data is cryptographically sealed the moment it's created. Any alteration, however small, is instantly detectable.
2.
Immutable
Every decision is mathematically bound to every other. Nothing can be altered or removed. The structure is mathematically guaranteed to hold.
3.
Permanent
Secured on a public, decentralized ledger that no one, including us, can control, take down or modify.
4.
Verifiable
Every proof can be verified independently by anyone, anywhere, anytime. No account. No permission. No middleman.
5.
Signed
Every decision is cryptographically signed by a registered identity.
6.
Private
Sensitive data never leaves you. Everything is sealed locally before it reaches us.
Simple, usage-based pricing
Every stamp is a blockchain proof. Verification is always free, on every plan.
