The team behind Zakura wants every swap through NEAR Intents to get its own key, so a refund address left on NEAR’s public chain can’t expose a user’s wider payment history. The team behind Zakura, a newer version of the software that runs the Zcash network, wants to give every ZEC swap made through NEAR Intents its own private key. The change would close a gap that a future quantum computer could use to piece together a user’s payment history, according to a new engineering post from the team. NEAR Intents is a service that lets users swap tokens across different blockchains. When someone swaps private ZEC for USDC through it, the service posts one of their private Zcash addresses on NEAR’s public chain, so it knows where to send back any unused ZEC. That address goes up as soon as the deposit lands and stays there even if the swap goes through and no refund is ever needed. Such addresses give away no information on today’s computers. Each Zcash address carries a public key built…
