#ATWO: Fans Vote to Change Live Outcomes #ZEST: Bitcoin Lending Protocol #World Cup Predictions: 100,000 USDT Daily StarkWare introduces 'Private KYC' to address personal data breachesZero-knowledge scaling company StarkWare has introduced Private KYC on Starknet, enabling users to complete know-your-customer requirements without revealing their full personal information.
The system, announced Tuesday as a demo, uses STRK20 privacy features and zero-knowledge STARK proofs to let users prove specific attributes, such as being older than 18 or holding valid credentials, without revealing their full passport details or address.
“Whether you need to prove you’re over 18, hold a valid credential or meet an eligibility rule, verification should only confirm the precise fact,” StarkWare said. Corporations should not collect the full identity behind it, “because every identity database becomes a liability the moment it exists.”
KYC compliance involves handing over personal information and trusting companies to keep it safe. The rollout comes as the US hit a record 3,322 data compromises in 2025, a 79% increase over five years, and the global average cost of a data breach is $4.4 million, according to StationX.
StarkWare users start by scanning their passport on their phones, using the camera and NFC chip to read and confirm the document is genuine and signed by its issuing authority.
They can then encrypt identity data to their Starknet wallet, register attributes in a public onchain registry, and submit zero-knowledge proofs for selective checks. Verifiers can confirm eligibility by reading the public registry without ever seeing the actual identity data.

“Private KYC shows that verification and privacy aren’t a trade-off,” StarkWare said. “An institution can confirm exactly what it needs without assembling another copy of someone’s identity it then has to defend.”
