Aqua V4 is the trust infrastructure for the AI era.
Identity. Access Control. Provenance.
Cryptographic proof that the data you use, produce, and share is real.
AI is generating content, making decisions, and accessing systems at unprecedented scale. But there's no infrastructure to verify any of it.
“Very soon, if not already, security will become THE bottleneck for effectiveness and usefulness of AI agents as a whole, since intelligence is still rapidly scaling and is no longer an obvious bottleneck for many use-cases.”
It's not just the market — regulators on both sides of the Atlantic are converging on the same conclusion: AI systems need verifiable provenance, identity, and audit infrastructure. This is becoming law.
The National Telecommunications and Information Administration called for public input on AI accountability, receiving 1,400+ comments. The resulting 2024 report explicitly recommends investment in:
The world's first comprehensive AI regulation. Entered into force August 2024, with obligations phasing in through 2026. Non-compliance carries severe penalties.
AI agents act on behalf of users, but there's no way to verify who they represent. Spoofed identities, unauthorized delegation, zero accountability.
AI models consume data from everywhere. No granular access control. No audit trail. No way to know what data was used, when, or by whom.
Where did this data come from? Was it tampered with? Is this output real or generated? Without provenance, AI outputs are just noise.
A cryptographic protocol that gives AI systems what they're missing: verifiable identity, granular access control, and tamper-proof provenance.
Self-sovereign identity with cryptographic attestation. Every agent, every model, every user — verified and accountable.
Granular, cryptographic access policies. Control exactly who and what can read, write, or delegate across your data.
Every piece of data carries its full history. Tamper-proof, portable, and independently verifiable — no blockchain required.
Aqua combines cryptographic hash chains, modular signatures, optional timestamping, and decentralized verification to create trust without central authorities.
Aqua creates AquaTrees — portable data structures that record a complete history of revisions with cryptographic precision. Every change is chained, every version is preserved.
Aqua supports multiple signature schemes — Ethereum wallets, DIDs, X.509 certificates, and more. The signature layer is modular by design: plug in the cryptographic paradigm that fits your security requirements without changing the protocol.
Anchor your data to tamper-proof timelines — via Ethereum blockchain, qualified TSA services (eIDAS-compliant), or both. Blockchain is optional — Aqua integrates with existing institutional infrastructure and decentralized networks alike.
Aqua bridges institutional and decentralized worlds. Use enterprise registries for regulatory compliance or community-driven decentralized registries for open verification — or combine both. One protocol, every trust model.
Aqua V4 is fully open source. Trust infrastructure cannot depend on a single vendor — it must be auditable, forkable, and verifiable by anyone. Free to build on. Enterprises deploy with production-grade infrastructure, compliance, and SLAs.
Full protocol specification, verification trees, and SDK — publicly auditable.
Interoperable by design. Every implementation strengthens the verification network.
Build free. Deploy with production-grade infrastructure, SLAs, and compliance.
