What is RAIN · a field note
Everything that matters is a copy somebody else holds.
Your deed. Your medical file. The vote you cast. The evidence in a case. Each one lives on a machine you have never seen, and is only as safe as the people allowed to change it.
What we do today
Three ways to keep the truth safe. Three fires waiting to happen.
Most records that matter live inside a familiar bargain: hand one keeper the copy, and trust them to keep it safe. The bargain can hold for years. Then a person makes a quiet edit, a company turns off a server, or an office discovers its backup was never tested.
-
Trust a person.
A clerk, a records officer, a notary. Honest people, mostly. But one login, one bad day, one quiet edit, and the record says something it did not say yesterday. Nobody can tell, because no independent copy can prove what came before.
-
Trust a company.
A cloud. A vendor. A subscription. The file is safe until the company is sold, hacked, or simply turns the servers off. When one operator holds the record, everyone else has to accept its account of what happened.
-
Trust the government.
Public institutions keep the facts we share: laws, votes, evidence, ownership, history. Because it all sits in one place, they can also restrict it, alter it, or build systems that watch people simply to protect the pile. Every time trust breaks, the answer is more cameras, more logs, more watching.
We don't need surveillance. We need something that can't be quietly changed.
The idea
Nobody holds the copy. Everybody holds a piece. The pieces check each other.
That's RAIN. A file is locked, broken into pieces, and the pieces are spread across a village of small, ordinary computers in ordinary homes and offices. No one machine has the whole file. No one machine can read its piece. And there are more pieces than you need, so losing a few loses nothing. Together, they can always bring the original back.
Why it holds
Why it can't be quietly changed or lost.
-
01
It repairs itself.
Unplug a node. Drop it in a river. The others notice the missing piece and regrow it somewhere else. The file never knew anything happened. A failed machine is a routine repair, not a lost record — there is no backup, because the whole thing is the backup.
-
02
It notices tampering.
Every piece carries a fingerprint, and the nodes never stop comparing fingerprints. Change one letter of one piece and it stops matching the rest. The village throws the bad piece out and rebuilds it from the pieces that still agree. A quiet edit is not quiet here.
-
03
It outlasts us.
The math has been done. A village of thirty-six ordinary nodes is expected to keep a file intact for longer than the Earth has existed. Not because the machines are good, but because there are enough of them, they keep extra pieces, and they never stop checking.
The full engineering — how the pieces are sized, how a village is organized, how the checking works — is written up for the people who want it. For engineers → Read the paper →
Where the rain is needed
Trust is on fire wherever a fact has to stay available, unchanged, and provable long after the people and machines around it are gone.
- CourtsCase files that no one, on any side, can alter after the fact.
- ElectionsA record of the count that every party holds a piece of.
- Public recordsDeeds, licenses, minutes, budgets, that survive the office that made them.
- ContractsOne agreement every party can prove, not competing copies controlled by one side.
- EvidenceA chain of custody that is checked by machines, not sworn to by people.
- AIThe source material and the decisions people need to examine when a machine makes a claim.
And the data centers?
We are told the future needs more of them.
Bigger buildings, more power, more of the world's information in fewer hands. Data centers already use more than three percent of the world's electricity — a larger carbon footprint than every plane in the sky. And what they give us in return is a bigger copy for someone else to hold.
RAIN points the other way: many ordinary devices, the size of a deck of cards, each caring for a small piece, checking one another, healing damage without a central keeper. Living systems survive this way. So did the original Internet.
We don't need giant data centers. We need more trust.
We don't need surveillance. We need truth.
Stay informed.
We send a short note when there is something real to say. Nothing else.
