A new proposal from Zcash software developer Zakura focuses on one of those points: the refund addresses involved when shielded ZEC moves through NEAR Intents.<\/p>\n<p>A publicly visible address can be linked to a wallet\u2019s viewing-key structure. If future cryptographic advances allowed an attacker to recover or exploit that relationship, exposing one address could reveal more of a user\u2019s transaction history than intended.<\/p>\n<p>Zakura\u2019s proposed answer is to give each swap its own viewing key while leaving spending authority under the user\u2019s control. A compromised viewing key would then reveal information related to one swap, rather than opening a window onto an entire wallet\u2019s past.<\/p>\n<p>The design also contemplates private information retrieval, allowing software to locate relevant refunds without broadcasting which addresses a user is checking.<\/p>\n<p>This isn\u2019t a response to a demonstrated quantum attack against Zcash. It is preventative engineering based on a possible future risk. The proposal remains under review, and supporters have not yet delivered a widely deployed solution.<\/p>\n<p>That distinction matters. Good privacy work often means fixing linkability problems before they become exploitable, but protection must still be implemented, audited and adopted by <a href=\"https:\/\/bitcoinist.com\/glossary\/wallet\/\">wallets<\/a> before it benefits ordinary users.<\/p>\n<p><em>Written by the News Desk and edited by Samuel Rae.<\/em><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>TL;DR: Zakura has proposed assigning a separate viewing key to each Zcash swap made through NEAR Intents, reducing how much transaction history a future attacker might be able to link.
