Registry Tiers
Three stages of joining Landblock — from a simple proof anchor to full cross-border federation.
Overview
Landblock uses a tiered conformance model. Registries don't have to commit to full integration upfront. They start at the level that makes sense for their capacity and legal environment, then graduate over time.
Tier 1 — Mirror
The entry point. A registry publishes cryptographic proofs of its records to Landblock. That's it. No change to internal systems. No change to legal processes. No bilateral agreements required.
In Mirror Mode, the registry decides what to publish and when. External parties can verify proofs, but the underlying data stays entirely with the registry. This is the lowest-friction way to make a registry's records globally verifiable.
- Publishes cryptographic hashes of records
- Zero change to internal registry systems
- Registry controls all disclosure
- Records become globally verifiable on publication
Tier 2 — Verified
A Verified registry has completed a Landblock conformance review and participates in the federated verification system. Cross-registry queries can be routed to and from it. Verified registries use DID-based identity (W3C Decentralized Identifiers) so that parties can prove rights without exposing personal data.
- Passed conformance audit
- Participates in cross-registry query routing
- DID-based identity for privacy-preserving verification
- LADM-structured proofs (ISO 19152 compliant)
Tier 3 — Full Federation
Full Federation registries have direct relationships with other registries in the network. They can share evidence, participate in dispute interoperability, and use the full Federation Liaison Service — including the facilitated registry-to-registry channel for complex cross-border queries.
- Direct federation relationships with other registries
- Shared evidence exchange
- Dispute interoperability (proof challenges)
- Full Federation Liaison Service access (Tiers 1, 2, and 3)
Graduating between tiers
Graduation from Mirror to Verified requires a conformance audit approved by the Landblock DAO. From Verified to Full Federation requires a direct federation agreement with at least one other Full Federation registry. Each stage is voluntary — a registry can remain at Mirror indefinitely.
