Can you build a rule into money?

Part 2 of a series on smart money — live and open at boundedeconomy.com.

A floor nobody falls through. A ceiling the pile can't cross. It sounds like a wish — you can pass a law about money, tax it, fine it, but the money itself just does what money does, and the law turns up later with a clipboard.

But the rule doesn't have to chase the money. It can be baked in.

Put the rule inside the money.

You already know the shape of this from somewhere unexpected: a smart contract. Strip off the crypto casino and the good idea underneath is plain — rules written as code that runs itself. No one to lobby, no back-room rewrite at 2am. The rule just executes, the same instant, for every account, no exception line to wait in. There's no referee left to buy — you can't bribe arithmetic.

And you already trust money built this way. Airline miles. The credits in a game. Switzerland has run a closed business currency — the WIR — since 1934, through a depression, a world war, every boom since. Rule-bound money you can't cash out and never think twice about. We do this constantly. We just never aimed it at the part that matters.

So here are the rules.

Five of them, each ordinary alone. Together they change what money can do.

• A floor. The same basic stipend for every member, every month, no forms. Nobody starts at zero.
• Earn by helping. Do what people actually value — bake, fix, teach, care, build — and they pay you. More useful, more earned.
• A ceiling that converts. Earn past the cap and the surplus isn't taken. Part becomes your own locked savings; part tops up a common pot that lifts every floor.
• Decay. Money you sit on melts a little each month, so it keeps moving instead of pooling.
• One human, one account. So the floor and the cap bind a person, not a wallet — no ten accounts to collect ten floors.

Almost none of this is new. Mondragon has capped pay by member vote for decades; Italy makes the commons share law. The cooperative movement road-tested the pieces. Three things are actually ours: a floor that asks nothing, money that melts, and all of it fused into one.

The one people flinch at is the ceiling. So sit with it.

The cap converts. It doesn't confiscate.

Maya bakes the best bread in town, line out the door, earning many times the floor. She hits the cap. Past it, the extra doesn't vanish — some becomes her own bounded savings, the rest tops up the town pot that pays everyone a little back. She still did great. Rich by every measure that was ever real. What she can't do is buy the town.

Capped isn't robbed. It's success that just can't turn into a lever over the people next to her.

Pay them in something money can't buy.

But cap the paycheck and nothing else, and people coast. Why push for the eighth multiple when the wallet stops at five? Effort drops. The cap can't be the whole design.

So, the quiet sixth rule: recognition. Do something people value and you earn visible standing — a public record of what you've built, that you can't buy, sell, or leave to your kids. Give it real weight and the drive comes back. In the simulation, output falls by half on a capped wage alone, then climbs back to full once recognition pays. Capped wallet, full effort. I didn't expect that to work. It does.

Rules you can read — and change in the open.

All of it is code, not a handshake. You can read it, run it, hold it against what the ledger actually did. The rules and the books, open.

Rules still have to change — a community isn't a frozen contract. But not in the dark. A change is proposed in the open, voted on, and made to wait before it bites — long enough that anyone who hates where it's heading can walk first. The dial can move. No one can move it on you.

Not "trust us." Trust you can check, and leave the day it stops adding up.

It won't make you rich.

That's the point — you can't pile up here. It doesn't trade, and there's nothing to cash out. It's voluntary, and it runs alongside normal money, not instead of it. And it's early: the hardest parts — proving real people, the edge where this touches real money — are flagged in big letters, not hidden.

Human endeavor, back in our hands.

Part 1 ended bleak — talent and effort aimed at the vault instead of the future, by a money that quietly sets the agenda. Flip the money and you flip that. When the rules answer to the people in the economy instead of the pile, effort points back at what people actually need.

And nobody hands these rules down. They're open — free to read, run, fork, and build on — by the people who'd live in them. Most of the internet already runs on code like that, owned by no one.

Whether all of it actually runs, or is just a tidy diagram — that's the next thing. Let's build it.
