Zcash launches Zakura full node to target Visa-scale privacy throughput
Zakura will support the Ironwood (NU6.3) upgrade, activating July 28, and is built to improve performance while preserving full verifiability and strong privacy.
CoinDesk reports Zcash has released Zakura, a new Zcash full node maintained independently of the Zcash Foundation, as a pruned, fast-syncing fork of Zebra. The software is scheduled to operate alongside legacy zcashd compatibility and comes ahead of the July 18 end of life for zcashd.
The launch is positioned as the first live component of a broader scaling effort, including Project Tachyon and private information retrieval research, aimed at moving Zcash toward payment-network scale by shrinking verification data and removing wallet performance bottlenecks. CoinDesk notes the goal is to reach tens of thousands of payments per second while keeping full verifiability and privacy guarantees.
Zakura is designed to support the Ironwood (NU6.3) upgrade, which activates July 28, according to CoinDesk. The upgrade introduces a turnstile mechanism intended to cap withdrawals from the Orchard shielded pool and contain any counterfeit ZEC that could be created through a long-standing soundness bug.
CoinDesk adds that Zakura is maintained by Sean Bowe and Dev Ojha, with their work funded by private ZEC donations rather than by a company or the Zcash Foundation. The outlet also describes the node concept, noting a full node keeps and independently checks a complete copy of the blockchain ledger against the network’s consensus rules.
