# The Registry

> Browse, filter, and search every attestation in the chain layer

> The registry at [proof.deepidv.com/registry](https://proof.deepidv.com/registry) is the searchable surface across every public attestation.

## Browsing attestations

Use the registry to:

* Confirm a specific attestation exists (paste the ULID or envelope hash prefix)
* Audit an issuer's volume and patterns
* Inspect attestations across a specific segment

## Filters and search

Every filter is URL-state-backed — you can share a link to a filtered view, bookmark it, or paste it into a report.

| Filter               | What it does                                                                                              |
| -------------------- | --------------------------------------------------------------------------------------------------------- |
| **Record type chip** | `IDV` active. `BIO` / `DOC` / `ADDR` show as "Phase 2" disabled. `WIT` / `AGT` not yet visible (Phase 3). |
| **Search box**       | ULID, envelope hash prefix, or issuer ID                                                                  |
| **Issuer dropdown**  | Restrict to one issuer at a time                                                                          |
| **Segment number**   | Restrict to one segment at a time                                                                         |

## Privacy posture

The registry surfaces only the public, non-identifying fields. You'll see:

* The attestation ULID (random, not derivable to a user)
* The pseudonymous subject ID
* The issuer ID
* The envelope hash prefix
* The mint timestamp
* The segment

<Warning>
  You will **never** see, in the registry or anywhere on the explorer: real names, email addresses, phone numbers, passport numbers, document numbers, or any other PII.

  Label values longer than 64 characters are server-side redacted with the placeholder `[committed but not revealed]`. Salt values are never published anywhere — not in the registry, not in attestation detail pages, not in proof bundles.
