On-chain confidential payroll is great — but employees still need to PROVE their income to banks, landlords, embassies, and lenders. Every existing FHE payroll system fails here: the salary is confidential… but unverifiable to third parties.
We can use ZK Attestation

ZK attestation helps — but it shifts the trust model.
You end up proving something about a value that was either revealed or attested off-chain at some point.
The hard part in payroll isn’t just proving income — it’s doing it while keeping the salary confidential throughout the entire lifecycle.
That’s where FHE becomes interesting:
- salary stays encrypted end-to-end
- payroll execution happens on ciphertext
- payslips can be generated as verifiable outputs without exposing raw values
So instead of proving “a known value”, the system proves properties of a value that is never revealed in the first place.
That’s the gap I’m trying to address with this system.
