Data Sovereignty

What Landblock can access, what it cannot, and how national law stays in control of your data at every stage.

The core principle

Your land data belongs to your jurisdiction. Landblock enforces a strict Data Sovereignty Policy: no land data is accessed by Landblock beyond what is operationally necessary to verify a proof.

This is not just a policy statement — it is enforced by the architecture. Land records are never stored on-chain. Off-chain evidence is stored on IPFS under access controls set by the registry. Landblock stores cryptographic hashes — fingerprints, not records.

What Landblock stores

• Cryptographic hashes (proofs) of records — not the records themselves
• IPFS content identifiers for supporting evidence — not the evidence itself
• Temporal metadata (timestamps, supersession references)
• Registry DID and conformance tier

What Landblock does not store

• Names, addresses, or personal details of landowners or rights-holders
• Survey documents, deeds, or boundary agreements
• Any content that national law classifies as restricted or sealed

Who controls disclosure

The registry controls its disclosure policy. Each record is classified as public, restricted, or sealed. Restricted records are accessible only to accredited institutions. Sealed records are accessible only under court order or by the registry authority. Landblock enforces these classifications but does not set them.

National law governs

If national law requires that certain records be withheld from foreign institutions, that requirement is respected. If national law restricts access to land ownership information for privacy reasons, those restrictions apply. Landblock does not override national law — it provides the infrastructure to implement it consistently.

The DAO and your data

The Landblock Protocol DAO governs the protocol — conformance standards, fee structures, and registry accreditation. It does not govern land records, does not have access to registry data, and is constitutionally prohibited from acquiring authority over land outcomes. This constraint is protected by an 85% supermajority requirement and 90-day deliberation window.
