Frequently Asked Questions on Anonymous Provenance
Get clear, technical answers on how we implement anonymous provenance systems that protect user privacy while ensuring regulatory compliance and auditability.
We implement a multi-layered cryptographic architecture using zero-knowledge proofs (ZKPs) and selective disclosure mechanisms. User identities are never stored on-chain. Instead, we generate unique, non-correlatable identifiers (like Semaphore-style nullifiers) for each interaction. The provenance of an asset is cryptographically linked to these anonymous identifiers, allowing verifiers to confirm the chain of custody without revealing who the participants were. All data processing follows GDPR's 'data protection by design' principle.
