Protect our land papers from forgery
Your family can fix a permanent, dated record of its land papers this week. Store a copy and its fingerprint, then have neighbours and elders sign a witness statement onchain. A later forgery or a lost folder becomes much easier to challenge. It backs your title as evidence; the registry and courts still decide ownership.

Chapter 1
Who knew?
Georgia's public registry began recording land titles on a private blockchain anchored to Bitcoin in 2016, built with Bitfury.
Any change to a file, even one digit, changes its fingerprint completely, so an edited copy is easy to spot.
Neighbours and elders can sign a statement about who has farmed a plot, dated and public.
Securing a land claim means lawyers and repeated trips to the registry.
A small scan stores permanently for free through ArDrive Turbo, and attestations cost a fraction of a cent on Base. Registering or defending title legally still costs what it costs locally.

A date nobody can backdate plus people who saw the paper.

The scan lives forever and the family decides together who can act.
Why it works Permanent storage plus multisig control.
- a registry+Propy=
Where a registry partners, the title itself can move onchain.
Why it works Propy runs onchain property closings in some US counties.

Where it matters most
- families with customary land

A permanent copy means the papers do not depend on one relative's cupboard.

Questions
Does putting my land title on a blockchain make me the legal owner?
No. Ownership is decided by your country's registry and courts. An onchain record is supporting evidence only.
Should I upload my full land documents publicly?
Think carefully. Deeds can contain private details. Storing only a fingerprint proves the file existed without showing its contents.
Will a court accept a blockchain record of my land papers?
It depends on the country and judge. Some accept digital evidence; never assume it. Ask a local lawyer.
What is a document fingerprint and how is it checked?
It is a short code made from the exact file. Anyone with the original can recompute it and see if it matches the stored record.
If a cousin produced a different deed tomorrow, what dated proof could your family show?
Some links are referral links; they never change what we recommend.
