Transparent bitcoin for the public sector
Automated tax compliance. Real-time fiscal visibility. One shared ledger instead of a hundred disconnected systems.
Citizens
Lower tax rate. Public dashboard. No hidden data brokers.
Businesses
Tax leaves your hands at the moment of sale. No filings. No audits. Qart handles keys.
Government
Revenue arrives instantly. Same net at a lower rate. Real-time economic intelligence.
How it works
Sale happens
Customer buys a coffee, a book, a hotel room. Normal POS interaction.
Tax splits atomically
One Bitcoin transaction, two outputs. Merchant gets the subtotal. City gets the tax. Same moment.
Receipt on-chain
A hash of the receipt is committed to the blockchain. Content stays private. The commitment is public.
City sees it
The treasurer's dashboard updates in real time. No filing. No waiting. No reconciliation.
Operations
Automation and compliance. Existing staff, better tools.
Tax rates from the city
Signed rate schedule. POS fetches automatically. No manual entry. No stale rates.
Key management is invisible
Merchants don't manage keys. Qart handles custody. Rotation is automatic.
Daily reconciliation
Every midnight: aggregate, group by merchant, sign, push to dashboard. Anomalies flagged automatically.
Audit = hash comparison
Hash the receipt. Compare to on-chain commitment. Match = authentic. No forensic accounting.
Business licenses on-chain
Verifiable, auto-renewing, revocable. Anyone can confirm a license without a phone call.
Short-term rental compliance
Per-property occupancy tax tracking. Bookings without attestations get flagged.

Transparent by choice
This data is already being collected by payment processors and analytics vendors — opaquely, without merchant knowledge, sold to third parties. On-chain, the merchant knows what's visible and consents to it.
What's visible
That a sale happened. How much tax was collected. That it went to the city's address.
Symmetric information
The city and the merchant see the same data. No back-channel telemetry. Just a shared ledger.
What stays private
What was purchased. Who the customer was. Only a hash goes on-chain.
Better than the status quo
Stripe, Square, and Clover see everything. Merchants have no visibility into who else accesses that data. This is strictly better privacy.
The fiscal case
Traditional compliance costs 2–5% of collected revenue. On-chain eliminates filing, reconciliation, and delinquency. The rate drops. The net revenue stays.
| Scenario | Rate | Collected | Admin | Net |
|---|---|---|---|---|
| Traditional | 8.25% | $12.0M | $360K | $11.64M |
| On-chain | 7.75% | $11.3M | $40K | $11.26M |
Money arrives instantly
Not 30–90 days later. Budgeting shifts from forecasting to accounting.
Real-time intelligence
Which districts are thriving. Seasonal patterns as they happen. Early warning when sectors contract.
Innovation signal
The city that does this first becomes the city others study. Attracts businesses, talent, and better bond ratings.
