Proof for everything AI makes.
In plain English: EpochCore signs and seals every output an AI produces the moment it's made — so anyone can prove what it said, who's accountable, and that not a single byte changed. Not another model. The layer no model can be.
The smarter AI gets, the more the world needs the one thing AI can't be on its own — accountable.
AI can't vouch for itself.
Companies are handing AI real decisions — money, contracts, medical notes, the content people see. When something goes wrong, "the model said so" isn't an answer a court, a regulator, or a customer will accept. AI can generate anything, including a convincing story about what it did. Proof has to come from outside the model.
It can't sign its own work.
A real signature needs a private key the model can never see or reach. Ours is held in an IBM hardware security module — out of the AI's hands, by design.
It can't be its own witness.
Accountability needs an independent referee — not the AI grading its own homework. EpochCore is the witness that sits beside every output and records what happened.
It can't outlast tomorrow.
Today's signatures break the day quantum computers arrive. Ours are post-quantum by default — built on the new NIST standards, so the proof still holds in ten years.
Sealed at the source. Verifiable by anyone.
EpochCore is invisible middleware that sits in front of your AI. It can't be skipped, and it adds three steps no one has to think about.
Don't take our word for it. Verify it.
Below is the real principle, running in your browser right now — no server, nothing uploaded. Seal a line of text, then change one character and watch the proof break. This is exactly how EpochCore catches a tampered AI output.
Shown here with SHA-256 and a real in-browser Ed25519 signature. In production, every output is sealed with a post-quantum triple signature (Ed25519 + ML-DSA-87 + SLH-DSA), keys held in an IBM Key Protect HSM, and anchored to an independent record. See how it works →
Not a deck. A running system.
EpochCore is in production today, sealing real workloads on IBM's enterprise AI and quantum infrastructure — not a prototype waiting for a roadmap.
Twelve agents. One sealed backbone.
Each EpochCore agent puts 8–10 domain specialists behind a single IBM watsonx Orchestrate chatbox. Every answer it returns is sealed and HSM-attested — provable to an auditor without EpochCore in the loop. Eight are live in production today; four are wiring up.
Why it matters: the same seal that protects one AI output protects an entire fleet of them — every agent, every vertical, the identical tamper-evident proof. One backbone, sold twelve ways.
The rules are already being written.
Regulators aren't waiting for AI to mature. Every framework below already demands tamper-evident records of automated decisions — and that's a starting gun, not a finish line. EpochCore is the only proof layer that's post-quantum by default and verifiable without the vendor in the loop.
EU AI Act · Article 12
High-risk AI must keep automatic, tamper-proof logs of what it did. Enforcement is phasing in now.
SEC 17a-4 · FINRA 4370
Regulated firms must retain write-once, tamper-evident records — for years, provable on demand.
SOC 2 · audit trails
Every enterprise buyer now asks how you prove what your AI produced. "Trust us" no longer passes.
Deepfakes · authenticity
As synthetic media floods every channel, "is this real?" becomes a question every platform must answer.
