The chain layer is the cryptographic transparency substrate underneath every deepidv verification — a public, append-only log anchored hourly to a blockchain.
When a verification is minted — a KYC check, document validation, address proof, agent identity — the chain layer produces a signed envelope, places it in an append-only log, and emits hourly checkpoints anchored to a public blockchain. The result: anyone, anywhere, in any language, can verify that a specific verification happened, when it happened, who issued it, and that the record has not been changed since. Without trusting deepidv. You do not need a deepidv account to use the chain layer. The explorer at proof.deepidv.com is public. The SDKs are open. The proof bundles are downloadable, verifiable offline, and portable.

​
Why it exists

Trust in identity verification has always been “trust us” — the issuer says they verified you, and downstream parties accept the issuer’s word. That works when the issuer is reputable, accountable, and reachable. It breaks the moment any of those three fail. The chain layer replaces “trust us” with “verify for yourself.” Every attestation deepidv issues is committed to a public, append-only, cryptographically signed log. Auditors, regulators, counterparties, and consumers can verify the same record without going through deepidv at all.

​
The 60-second mental model

1

An issuer verifies a subject

A deepidv tenant (the issuer) verifies something about a subject — a person, organization, or agent.
2

A signed envelope is produced

The chain layer produces a signed envelope — a JSON record bound to the issuer’s key, the verification result, and a set of label commitments that bind metadata without revealing it.
3

The envelope lands in a segment

The envelope is appended to a Merkle tree called a segment.
4

An hourly STH is broadcast

Every hour, the segment’s tree root is signed (a Signed Tree Head, or STH) and broadcast to the Base L2 blockchain.
5

Anyone can download a proof bundle

With the attestation ID, anyone can download a proof bundle (a .dpiv file) containing everything needed to verify the chain of signatures end to end.
That’s it. The rest of this documentation explains each piece.
