Key Highlights Testing of Zakura, a new Zcash node client by Valar Group and Project Tachyon, demonstrated 25-second block intervals across 80 nodes in 11 regions. Faster block times increased the orphan block rate to 3.43% under maximum transaction loads, compared to 1.57% under the legacy 75-second cadence. The upcoming NU7 upgrade introduces block limits ...
Key Highlights Zcash developer Sean Bowe proposed activating the privacy-focused blockchain upgrade NU7 at block 3,543,405, following agreement by Zcash Improvement Proposal editors. NU7 would reduce block times from 75 seconds to 25 seconds, cutting the wait for three confirmations from nearly four minutes to about 75 seconds. Zakura’s public upgrade dashboard lists block 3,543,405 ...
Key Highlights Theoretical quantum computing attacks utilizing Shor’s algorithm threaten historical, Satoshi-era Bitcoin public keys currently exposed onchain. Google’s recent Willow quantum chip milestone demonstrates advancement in hardware components necessary for long-term quantum computation, accelerating industry mitigation efforts. Zakura has implemented an architectural safeguard for Zcash transactions across networks like NEAR, assigning distinct viewing keys ...
Key Highlights: Zakura has outlined a strategy to bring quantum-safe, unlinkable, rotating transparent addresses to Zcash using hash-based WOTS signatures and Private Information Retrieval (PIR). The proposal directly addresses signature vulnerability debates amplified by Ethereum Foundation researcher Justin Drake and Ethereum co-founder Vitalik Buterin regarding AI-driven cryptographic breakthroughs. PIR query technology is launching this week ...
Shielded wallets using Zakura Common and full nodes such as Zakura can benefit from Zcash’s new cryptography stack, according to Zcash cofounder Sean Bowe. “Shielded…
