Zcash upgrade trio targets 300% speed boost via NU7
The Zcash upgrade roadmap includes three advances targeting a 300% speed boost as ZEC gained 73% in a month.
- Zcash’s NU7, planned as the network’s ninth upgrade, will introduce Zcash Shielded Assets and a Network Sustainability Mechanism with more than 90% community support.
- Project Tachyon aims to scale shielded transaction throughput to thousands of TPS using proof-carrying wallets and oblivious synchronisation.
- FROST v3 brings threshold signatures with cheater detection by default, with the Zcash Foundation expecting finalisation in 2026 as part of the Z3 tech stack.
The Zcash Foundation outlined a three-pronged technical roadmap building toward NU7, its ninth planned network upgrade. The SEC also closed its investigation into the Zcash Foundation on May 20 with no enforcement action, removing a major regulatory overhang.
NU7 is planned to introduce Zcash Shielded Assets, allowing user-defined tokens within shielded pools with full Zcash-grade privacy, alongside a Network Sustainability Mechanism that modernises fee mechanics. Community sentiment polling found more than 90% support among ZCAP members and coinholders for Project Tachyon and Orchard Quantum Recoverability as NU7 priorities.
What each of the three upgrades does
Project Tachyon scales Zcash’s shielded throughput using proof-carrying wallets and oblivious synchronisation, targeting thousands of transactions per second. The upgrade removes runaway state growth for validators, eliminating the rising marginal cost that currently limits Zcash’s scale.
Crypto.news has tracked Zcash’s capital rotation dynamics and the structural drivers behind its recent 73% monthly rally.
FROST v3 brings flexible threshold signatures to Zcash shielded transactions with cheater detection enabled by default and stronger memory protection. The Foundation expects FROST v3 and ZIP-312 finalised in 2026 as part of the Z3 stack integrating Zebra, Zaino, and Zallet with built-in Tor support.
Why the quantum angle is driving fresh interest in Zcash
ZEC’s 73% monthly gain coincides with growing market attention to quantum-resistant protocols. Zcash’s zero-knowledge proof technology, which now underpins major Ethereum layer-2 networks, is being re-rated as infrastructure rather than speculation.
Crypto.news has covered the quantum threat timeline, including research showing Bitcoin’s elliptic curve cryptography requires approximately 2,330 logical qubits to break.
The NU7 upgrade includes Orchard Quantum Recoverability, enabling recovery pathways for keys that might become vulnerable to future quantum hardware. Citi’s analysis, as crypto.news reported, found a quantum attack on major financial institutions could put $2 to $3.3 trillion of GDP at risk. NU7’s quantum recovery component positions Zcash as one of the few protocols actively preparing for that scenario.
