The shared trust layer for land registries

Landblock is an open, neutral federation protocol that connects land registries across jurisdictions. Governments keep full authority over their records. Landblock adds the cryptographic infrastructure to make those records globally verifiable.

How it works

What Landblock does

Most countries have some form of land registry. The problem is that those registries cannot verify each other's records, operate under incompatible standards, and can only interoperate through slow, expensive bilateral agreements. A lender in Germany cannot easily verify a title in Kenya. A court cannot quickly access boundary evidence from a neighboring jurisdiction.

Landblock is not a registry. Landblock is a federation protocol that connects registries. Government registries remain the authoritative sources of truth for land rights. Landblock provides the shared trust fabric — the cryptographic infrastructure through which registries publish proofs, verify each other's records, and cooperate across jurisdictions without surrendering sovereignty.

Land data never lives on-chain. Landblock anchors cryptographic hashes of records to the blockchain, keeping sensitive data private while making the chain of custody publicly verifiable. Identity is handled through decentralized identifiers and zero-knowledge proofs, so participants can prove rights without exposing personal information.

Protocol design

Registries, not replacement.
Landblock connects existing government land registries without displacing them. Each registry retains full authority over its records and legal decisions. Landblock adds the interoperability layer — the shared proof standard that lets any conforming registry be verified by any other.
Cryptographic proof layer.
Registries publish signed proofs of their records to the Landblock federation, anchored on Polygon with off-chain evidence stored on IPFS/Filecoin. Any institution — courts, banks, other registries — can verify those proofs without contacting the originating registry directly.
Privacy-first identity.
Landblock uses decentralized identifiers (DIDs) and selective disclosure proofs to support privacy-preserving identity across jurisdictions. Participants prove rights without exposing personal information. Identity resolution follows sovereignty — each registry sets its own acceptance policy.
DAO-governed standards.
Protocol governance is handled by the Landblock Protocol DAO — governing federation conformance standards, the Global Directory of registries, and protocol upgrades. The DAO governs the protocol. Courts and governments govern land.

Platform applications

Landblock is built as a set of composable applications sharing the same protocol layer.
