ENTERPRISE

Transparent bitcoin for the public sector

Automated tax compliance. Real-time fiscal visibility. One shared ledger instead of a hundred disconnected systems.

Atomic Tax Split Hash-Based Audits City-Issued Rates

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

01

Sale happens

Customer buys a coffee, a book, a hotel room. Normal POS interaction.

02

Tax splits atomically

One Bitcoin transaction, two outputs. Merchant gets the subtotal. City gets the tax. Same moment.

03

Receipt on-chain

A hash of the receipt is committed to the blockchain. Content stays private. The commitment is public.

04

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
01

Money arrives instantly

Not 30–90 days later. Budgeting shifts from forecasting to accounting.

02

Real-time intelligence

Which districts are thriving. Seasonal patterns as they happen. Early warning when sectors contract.

03

Innovation signal

The city that does this first becomes the city others study. Attracts businesses, talent, and better bond ratings.
