$GRVT TL;DR Zakura proposes one-time incoming viewing keys for Zcash swaps, limiting how much a future quantum attacker could link if a shielded address is publicly exposed. The risk is theoretical today: it depends on sufficiently powerful quantum computers recovering a viewing key from an exposed address, not on a demonstrated breach. The design keeps spending authority unchanged and uses encrypted memos, filters and Private Information Retrieval to make wallet recovery practical. Zcash developers are proposing a wallet-level change to limit a future quantum privacy risk affecting shielded swaps. In a technical explanation, Zakura engineer Adam Tucker said shielded transactions remain private against quantum adversaries in many ordinary cases, but publicly posted shielded addresses create a different exposure. For readers following the Zcash privacy model, the proposal targets future linkability when swap addresses become permanently visible on another blockchain. One-Time Viewing Keys Aim to Limit Quantum Linkability The concern centers on swaps using NEAR Intents. A Zcash wallet can publish a shielded refund or recipient address on NEAR’s public chain, and diversified addresses from the same account normally share one incoming viewing key. A sufficiently powerful quantum computer using Shor’s algorithm could theoretically recover that key from one exposed address and link payments received across the account. This differs from an active exploit today and fits broader work on quantum-safe Zcash payments. The risk depends on future quantum capability plus access to an exposed shielded address. Zakura’s proposed solution derives a separate one-time incoming viewing key for each swap while leaving the account’s spending authority unchanged. If a future quantum attacker recovered the key associated with one published address, exposure would be limited to payments sent there rather than revealing the account’s wider receiving history. The design keeps funds spendable from the original account, avoiding problems created by generating a separate account for every swap. The objective is compartmentalization: one compromised swap address should not reveal unrelated shielded payments. Wallet recovery creates another challenge because every extra viewing key could otherwise require historical scan. The design records the swap index in an encrypted memo and uses public filters plus Private Information Retrieval to locate relevant NEAR payouts without revealing the queried address to the server. That approach extends privacy techniques around Zcash wallet infrastructure. PIR is intended to preserve practical seed recovery without forcing wallets to rescan the chain separately for every swap key. Zakura says software wallets using its open-source cryptography and wallet libraries, including Vizor, should integrate the one-time feature in coming weeks, while hardware-wallet support will require firmware changes. The work sits alongside post-quantum research such as Project Epoch, but it does not make Zcash universally quantum-safe. The proposal addresses a narrow privacy weakness in exposed swap addresses, not a demonstrated quantum breach of shielded transactions today.

$GRVT NEAR: ETF inflows and ecosystem growth continue fueling strong bullish momentum. ADA: Rising network activity and whale accumulation support a potential recovery. ZEC: Upcoming NU7 upgrade could drive renewed interest and price appreciation. The crypto market remains volatile, yet a few altcoins continue to show unusual strength. While many large-cap assets struggle to hold gains, several projects have attracted fresh buying interest and strong network activity. Some benefit from institutional support, while others draw attention through upcoming upgrades and growing adoption. For traders seeking opportunities before the next major move, NEAR Protocol, Cardano, and Zcash stand out as three altcoins worth watching closely in the coming week. Near Protocol (NEAR) Source: Trading View NEAR has emerged as one of the strongest performers among top cryptocurrencies. The token gained nearly 8% during the past day and more than 11% over the last week. A year-to-date increase of 245% highlights strong momentum. Current price action also reflects a remarkable recovery from levels below $2 in early September. Several factors support this rally. The recent launch of a spot NEAR ETF by Bitwise introduced fresh institutional demand. Fund inflows require direct purchases of NEAR, which reduces available supply and strengthens buying pressure. Beyond ETF demand, growth within the NEAR ecosystem continues to attract attention. NEAR Intents improves cross-chain transactions, while growing interest in artificial intelligence projects adds another layer of appeal. Combined, these developments create a compelling investment narrative for both retail and institutional participants. Cardano (ADA) Source: Trading View Cardano delivered one of the strongest rebounds of the week. ADA climbed to a multi-month high before a sharp market-wide pullback pushed prices lower. Buyers quickly returned, helping the token recover and post gains over the last 24 hours and the past week. What makes Cardano particularly interesting is the gap between price performance and network activity. Despite earlier weakness, daily active addresses increased significantly, suggesting growing user engagement. Such divergences often signal stronger demand beneath the surface. Additional catalysts strengthen the bullish case. Large holders continue accumulating ADA, while the recently launched RealFi initiative expands utility across the ecosystem. Zcash (ZEC) Source: Trading View Zcash represents the contrarian opportunity on this list. Recent price action has been weak, with losses during the past week and a sharp decline on Friday. Even so, a gain of more than 130% since the beginning of the year shows strong long-term performance. The biggest attraction lies in the upcoming NU7 network upgrade. Testnet activation already succeeded, and mainnet activation is scheduled for October 20. The upgrade introduces faster shielded transactions, prepares the network for Zcash Shielded Assets, and adds a sustainability mechanism for miners. Major upgrades often attract speculative interest before launch, making the coming week especially important for traders watching momentum shifts. NEAR stands out because of institutional demand and ecosystem growth. Cardano combines rising network activity with several positive fundamental developments. Zcash offers a higher-risk opportunity driven by a major upgrade catalyst. Together, these three altcoins deserve a place on any crypto watchlist heading into next week.

$GRVT Zcash infrastructure developer Zakura has proposed a new wallet feature that would protect users’ transaction privacy against potential future quantum computing attacks. The proposal would assign a separate incoming viewing key to every Zcash (ZEC) swap made through NEAR Intents. This limits the payment history an attacker could expose if they eventually break the cryptography behind a publicly visible address. The proposal, outlined by Zakura developer Adam Tucker on October 18, targets a specific weakness in cross-chain swaps. NEAR Intents publishes Zcash addresses on its public blockchain so unused funds can be returned if a transaction fails or does not use the full deposit. Those addresses remain visible even when no refund is required. Zcash’s shielded transactions are designed to hide transaction details, but addresses within a wallet typically share an incoming viewing key. A sufficiently powerful quantum computer running Shor’s algorithm could theoretically recover that key from an exposed address, potentially revealing the amounts and private memos of payments received by the account. No quantum computer capable of carrying out this attack has been demonstrated. Separate Keys Aim to Limit Potential Exposure Under Zakura’s proposal, each swap would use its own incoming viewing key while the wallet’s existing spending key remains unchanged. If a future attacker recovered the viewing key associated with one publicly exposed address, the information revealed would be limited to payments linked to that address rather than the wallet’s wider transaction history. The design also addresses the practical challenge of restoring wallets with many separate keys. Zakura proposes using private information retrieval (PIR), a technique that allows a wallet to locate relevant transactions in a database without revealing to the operator which addresses it is searching. The change would not require a Zcash network upgrade. Zakura says software wallets built with its open-source libraries, including Vizor, could integrate the feature in the coming weeks. Hardware-wallet support is expected later, once compatible firmware becomes available. The proposal comes as Zcash developers work toward broader quantum-resistant payment protections, including the planned Tachyon upgrade. However, Zakura’s design remains a proposed wallet-level safeguard, not a network-wide fix already deployed to all users. The immediate goal is to reduce the amount of private transaction information exposed in a hypothetical future quantum attack. The proposal also allows users to continue spending funds through their existing wallet accounts. [googlesitekit-end-of-content] TagsNEARNEAR Protocolquantum computingZcashZEC
