How to use this demo: Use Users and IOUs/user to set the network size, then hit Recalculate. Users are ranked by net position — largest credit at the top, largest debt at the bottom (ties broken by cooperative activity). Check Activity bias to make some users more active than others; unchecked, everyone is equally active.

Hit Jubilee! to settle everyone to ⊙0. This is not a write-off: each user in debt does work for the users in credit, and the settlement IOUs they receive exactly cancel what they owed. The rows below the gold divider show who did what for whom.

Click any user card to filter the ledger to just that user's IOUs. Click the activity line to expand a breakdown of cooperation by category, sorted by volume.

The Jubilee: Click Jubilee! to run net position settlement — watch as N−1 settlement IOUs bring every user to exactly ⊕0. Check Auto Jubilee to run it automatically after each Recalculate. Check Partial Jubilee to see what happens when half the users refuse to participate — the cooperators still benefit, the holdouts just keep their positions.

Amounts are in ⊕ (you) — one minute of human labour. The Proof tab explains why the sum of all net positions is always exactly zero, and what this means at planetary scale.
