How to use this demo: Use Users and IOUs/user to set the network size, then hit Recalculate. Users are ranked by cooperative activity — the total amount of time exchanged through their IOUs. Check Activity bias to make some users more active than others; unchecked, everyone is equally active.

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.
