Tax & Revenue on PYRAX
Tax and revenue administration must collect fairly, minimize fraud, and remain auditable, yet legacy systems suffer huge compliance gaps, refund fraud, and opaque assessment. PYRAX gives revenue agencies shielded citizen filings that stay private by default with viewing keys for lawful audit, on-chain escrow for automated collection and refunds, and verifiable computation so assessments can be proven correct.

What's broken today
How PYRAX transforms it
Concrete network elements mapped to this business.
Shielded-by-default privacy with viewing keys
Taxpayer filings, income, and account data stay encrypted and private, while auditors and courts access exactly what a lawful audit requires through scoped, logged viewing keys - private for citizens, auditable for the agency.
On-chain escrow + automated collection
Withholding, VAT, and installment payments are escrowed and settled automatically at the point of transaction, and verified refunds release directly to the taxpayer without fraud-prone manual disbursement.
PYRAX Compute verifiable public-sector AI
Fraud-detection and risk-scoring models run with cryptographic proofs, so a flagged return or denied refund can be shown to be fair, reproducible, and non-arbitrary to an appeals body.
eth_getProof verifiable assessments
An assessment is a verifiable function of declared, on-chain figures, letting a taxpayer independently reproduce and challenge the computation instead of trusting an opaque notice.
Self-sovereign identity + ZK selective disclosure
Taxpayers prove eligibility for a credit or exemption - income band, dependents, residency - through ZK selective disclosure without exposing their entire financial picture.
