What is a public blockchain in land registry?

A public blockchain in land registry is an open, decentralised ledger where property ownership records are stored and accessible to anyone without requiring permission. Land registry data is written to a public blockchain like Ethereum or Bitcoin, making it globally verifiable, censorship-resistant, and fully transparent.

How It Differs from Traditional Land Registries

• No single government or institution controls the records
• Anyone can verify ownership history without requesting official documents
• Records are secured by cryptographic proofs rather than physical stamps
• Transactions are visible to all but ownership is tied to cryptographic keys

Advantages

• Global accessibility: Useful for cross-border property investments
• Fraud prevention: Tamper-proof records visible to the public
• Cost reduction: Eliminates intermediary verification fees
• Speed: Title searches take minutes instead of days

Public blockchains in land registry offer unmatched transparency and security, but widespread adoption depends on overcoming legal, privacy, and scalability hurdles. They are most effective as complementary systems alongside existing government registries.
