MyZubster MVP — Dev Update: From Ledger to Revenue & Cost Simulation
Today we took another important step in the evolution of MyZubster MVP: moving from recording economic events to a system that can also simulate revenue, costs, and margins without contaminating real accounting data.
At the core is the MYZ Ledger, where economic events are recorded with explicit revenue sources, auditable allocation rules, and UTC timestamps. From these events, the system derives the MYZ Balance, while keeping internal accounting clearly separated from payments, wallets, custody, and on-chain activity.
We have now introduced the Revenue & Cost Simulator.
It allows us to model scenarios using variables such as transaction volume, average transaction value, Marketplace commission, Zorgax Pro and Developer users, payment processing assumptions, AI costs, hosting costs, and other operating costs.
The calculation flow is straightforward:
GMV → Marketplace + Zorgax revenue → Costs → Monthly Margin → Annualized Scenario
The most important architectural rule is that a simulation never creates an economic event in the MYZ Ledger.
A simulated result is not recorded revenue.
It is not a payout.
It is not wallet funds.
It is not certified profit.
And it is not a financial forecast.
We verified this boundary at runtime: after running the simulator, the Ledger remained at 3 events, confirming that simulated economic data was not persisted.
On the engineering side, the project has also reached 47 passing tests, covering revenue calculations, cost and margin calculations, negative-input validation, and the simulator API.
The next layer is the UI: bringing the Revenue & Cost Simulator directly into the MyZubster dashboard alongside MYZ Balance, My Assets, Revenue History, and MYZ Ledger.
The direction is becoming increasingly clear:
Evidence first. Economics explicit.
Don't ask AI to invent value.
Record the facts.
Declare the rules.
Simulate the scenarios.
Keep reality separate from projections.
