IOUNet replaces money with mutual cooperation — and proves mathematically that all debt can be eliminated. Six steps take you from first principles to a living global system. Start anywhere.
When Alice cooks dinner for Bob (60 minutes), she records an IOU: Bob owes Alice 60⊙. Bob tutors Carol. Carol fixes Dan’s bike. Dan babysits for Alice. The IOUs form a network of mutual cooperation. The key insight: the sum of everyone’s net positions is always exactly zero. Debt is not a thing that accumulates — it is a circular pattern that cancels by construction. The Jubilee proves it: with N users, at most N−1 settlement IOUs bring everyone to ⊙0.
Each step builds a different kind of conviction. Four are simulations that let you explore the idea. One is a hands-on tutorial. The last is the real thing.
No individual transaction history. Once an IOU is processed, only two numbers change: the net positions of sender and receiver. There is no ledger of past transactions. There is no history to leak, subpoena, or sell. The privacy story is not “we protect your data” — it is “there is no data.”
The best way to understand IOUNet is to see it work.
