Zcash has completed its decade-long software migration from the original zcashd client to the Rust-based Zebra and the new Zakura node ecosystem, marking the end of support for the legacy software on July 18th at block height 3417100. Despite the Orchard vulnerability, shielded transactions rose 11.1% quarter-over-quarter to 131,584, and the anonymity set expanded by 325,127 units to 124.08 million. The network now prepares for the Ironwood upgrade, which introduces formal verification and quantum recovery to strengthen long-term protocol security.
Zcash’s infrastructure entered a new phase as the network completed its transition away from the original software implementation. This evolution took nearly a decade, beginning with zcashd’s 2016 launch before Zebra’s 2024 release introduced a Rust-based alternative.
After the 2024 deprecation notice, node operators had enough time to switch over before the planned retirement. On the 18th of July, zcashd reached end of support at block height 3417100.
Zakura completed the new node ecosystem. Rather than simply replacing legacy software, the transition strengthens maintainability and prepares the network for Ironwood, reducing long-term operational risk.
Completing Zcash’s infrastructure transition did not remove the market’s biggest question. Instead, it shifted attention to whether users still trusted the network after the Orchard vulnerability.
Although shielded balances declined 14% to 4.42 million ZEC, users continued relying on private transactions, which rose 11.1% QoQ to 131,584. This trend became even more significant as the anonymity set expanded by 325,127 units to 124.08 million.
Average daily trading volume increased by 33.8% QoQ to $373 million. These trends point to cautious capital repositioning while confidence in Zcash’s privacy infrastructure remained intact.
Zcash faced a critical test when researchers found a flaw in Orchard shielded pools that secured roughly 85% of shielded value. The flaw stayed contained, as disclosure was coordinated and developers released an emergency fix within days.
The flaw allowed forgery inside Orchard rather than inflating the total supply of ZEC. The turnstile mechanism prevented forged funds from leaving the pool other than legitimate deposits.
Looking ahead, Ironwood strengthens this protection through formal verification and quantum recovery. Together, these upgrades move Zcash from reactive fixes towards stronger assurances of long-term security.
