ECONOMYENGINE / FOUNDATION
Exchange with provenance.
The demo records deterministic wages and meal purchases in integer minor units. A production double-entry ledger is defined in the MySQL schema but not connected to this browser demo.
DEMO CURRENCY / GCR
No real financial value
Genesis credits are a fictional, non-redeemable simulation currency. The LifeEngine pays wages once per citizen per simulated day and records purchases as world events. External payment and reward rails require separate authorization, reconciliation and production-grade controls.
