Stealth addresses are one-time cryptographic addresses generated by recipients for each transaction. Senders use a public key shared by the recipient to derive a unique address, ensuring funds are sent to a new address unlinkable to the recipient’s identity or previous transactions. This technique, used in Monero and Zcash, prevents address reuse and blocks chain analysis from tracking a recipient’s transaction history.

How is user consent managed in identity verification processes? User consent in decentralized identity is managed through explicit, granular permissions. Users control what data is shared, with whom, and for how long, using digital signatures or smart contracts. Decentralized systems often employ user-friendly interfaces to clarify data usage terms. Consent is revocable, allowing users to withdraw access instantly. This approach aligns with privacy regulations like GDPR, ensuring transparency and empowering individuals over their identity data.
