Zcash Targets Quantum-Resistant Upgrades for Transparent Transactions

The initiative, spearheaded by Zakura engineer Roman Akhtariev, focuses on implementing hash-based signatures—specifically Winternitz One-Time Signatures—to replace current elliptic-curve cryptography for transparent addresses. These addresses hold roughly 70% of the total ZEC supply, making them a primary point of concern regarding quantum vulnerability. Although the planned opcodes represent a defensive step, developers note that the network’s existing shielded transaction systems will require separate, more complex cryptographic overhauls to reach full quantum resilience.

In tandem with the signature upgrade, the Zakura team has introduced experimental private balance checks. By utilizing private information retrieval, this technology allows wallets to verify transaction history and balances without exposing address records to external servers. This feature addresses long-standing privacy gaps where standard synchronization methods could inadvertently link multiple addresses to a single user. As the engineering team moves toward their January milestone, ZEC continues to face market volatility. The token recently recovered to trade near $1,240, though technical indicators suggest persistent selling pressure with resistance levels looming at $1,305.
