Introduction

What Landblock is, what it is not, and why it exists.

The problem

Most countries have some form of land registry. The problem is that those registries cannot verify each other's records. They operate under incompatible standards and can only interoperate through slow, expensive bilateral agreements negotiated between governments.

A lender in Germany cannot easily verify a title in Kenya. A court cannot quickly access boundary evidence from a neighboring jurisdiction. A landowner displaced by conflict cannot prove their rights to an institution in another country.

These aren't edge cases. They affect millions of land transactions every year and disproportionately harm people in jurisdictions with weaker institutions.

What Landblock is

Landblock is an open, neutral federation protocol that connects land registries across jurisdictions. It provides the shared trust fabric — the cryptographic infrastructure through which registries publish proofs of their records, verify each other's records, and cooperate across borders without surrendering sovereignty.

Think of Landblock as the shared plumbing between registries. Each registry remains the authoritative source of truth for land rights in its jurisdiction. Landblock adds the interoperability layer — a shared proof standard that lets any conforming registry be verified by any other.

What Landblock is not

• Not a land registry. Landblock does not hold, adjudicate, or replace land rights. Courts and governments decide land truth. Landblock provides the infrastructure to verify it.
• Not a land data store. No land data lives on-chain. Landblock anchors cryptographic hashes of records to the blockchain. The underlying data stays off-chain, under registry control.
• Not a replacement for existing institutions. Landblock is designed to work alongside existing registries, legal systems, and government processes — not around them.

The approach

Landblock is built on Polygon PoS, an EVM-compatible blockchain checkpointed to Ethereum. Off-chain evidence is stored on IPFS and Filecoin. Identity is handled through decentralized identifiers (DIDs) and zero-knowledge proofs, so participants can prove rights without exposing personal information.

The protocol is governed by the Landblock Protocol DAO — governing federation conformance standards and protocol upgrades. The DAO governs the protocol. It never governs land.
