Where DCS Verify fits.
AI models, cloud providers, document-signing tools, and verifiable-credential platforms each solve a different piece of trust. Most systems do not produce a portable, independently verifiable receipt for what an AI agent actually did.
This is the map of that gap — and the layer that closes it.
A capability map, not a scoreboard. The organizations here solve different problems and many do their job extremely well — the point is simply that verifiable AI-action receipts are a category nobody else covers.
When an AI agent acts, can you prove what happened?
AI agents now make decisions, call tools, access systems, generate content, approve workflows, and perform real business actions. The moment one does, an organization may have to answer — to a regulator, a customer, or a court — exactly what occurred, who was responsible, and whether the record has been altered since.
A log records. It doesn't prove.
A traditional log answers those questions only if you already trust the system that wrote it. That's exactly the assumption an auditor, a regulator, or a counterparty can't make.
Can be changed
Log entries can be edited or deleted after the fact, with nothing to show the original ever existed.
No integrity proof
There's no way for an outsider to confirm a log wasn't altered — you simply have to take the operator's word.
Your word vs theirs
In a dispute, an internal log carries the weight of "trust us." Auditors must trust the very system under review.
A receipt is proof you don't have to trust.
Each receipt is signed by the issuer, linked into a tamper-evident chain, and anchored on a public blockchain — so anyone can confirm it independently, without contacting you and without trusting DCS.
Who did it
An Ed25519 signature binds the action to the issuer's key. The authorship is cryptographic, not asserted.
Whether it changed
Each receipt hash-links to the one before it. Editing, deleting, or reordering breaks the chain — visibly, to anyone.
Independently auditable
The chain's root is committed on Base mainnet. A third party can confirm it on-chain, no account and no permission required.
DCS Verify is the verification layer for AI actions.
It doesn't replace the layers below — it sits on top and makes their output provable.
Most AI agent systems can run.
Only DCS can prove what they did.

Every other system can run an agent. Only DCS issues a receipt that proves what it did — and lets anyone check it.
Everyone here solves a different problem.
The platforms below aren't on the matrix above — they're the layers DCS sits on top of. Each solves a different piece of the stack; none produces a verifiable receipt for what an AI agent actually did. DCS doesn't compete with them — it makes their output provable.
Portable by design. Not a silo.
Receipts are built on an open specification (the R-Series standard) and are content-addressed and portable. The reference verifier is open, so a third party can confirm your receipts without our servers — and where a deployment prefers W3C Verifiable Credential transport, a receipt can be embedded inside one. The receipt itself stays the lighter, high-volume primitive.
This is the gap DCS fills.
