• •Author of incoherency.co.uk introduced ProofToken16 as a protocol for verifying user age without revealing identity
• •The system utilizes zero-knowledge proofs to allow users to attest to being over a certain age while remaining anonymous
• •The proposal remains purely theoretical, with no functional implementation or audit history available to verify security or scalability

ProofToken16 has been proposed as a decentralized framework designed to verify user age through cryptographically signed tokens. This effort addresses a longstanding tension between platform age-gating requirements and user demand for data privacy, standing in contrast to traditional identity verification services that aggregate sensitive personal information. The protocol remains in a conceptual stage, however, and has not yet addressed the practical challenges of how authorities or users would reliably verify the initial issuance of such tokens. Whether the system can scale or resist sybil attacks remains the primary hurdle for its viability in a production environment.
