Zcash developers have reached a consensus on the Ironwood upgrade, which will introduce a new Orchard pool and restrict payment functionality in the old pool.
According to Foresight News , Sean Bowe, a core developer of Zcash, tweeted that Zcash organizations and protocol developers have reached an agreement on specific consensus rule changes for the Ironwood upgrade. Ironwood will introduce a new shielded pool using the Orchard protocol. Simultaneously, the Orchard circuit will add a consensus rule-controlled flag that disables payments to other users within the pool (while retaining change functionality) as a privacy protection mechanism. After the upgrade, the old Orchard pool will enable this restriction and prohibit fund transfers to the old pool by constraining valueBalance. New user payments must be made through the new pool, while migrating funds from the old pool to the new pool is encouraged. Furthermore, users can gradually prove that no fraudulent minting has occurred by migrating funds. Currently, all parties are in the implementation, specification development, and ecosystem support phase, and are advancing multiple auditing and formal verification processes.
ZODL has proposed launching a new privacy pool, Ironwood, with plans to activate and enhance Zcash security by the end of July 2026.
ChainCatcher reports that ZODL, a core contributor to the Zcash ecosystem, has announced a new network upgrade solution and privacy pool, Ironwood, in collaboration with Tachyon, Valar Group, Zcash Foundation, and Shielded Labs. Ironwood will be built on the existing Orchard protocol and further enhanced for security through formal verification and additional independent audits.
The Zcash Ironwood upgrade will be deployed to the testnet tomorrow.
According to Foresight News , Zcash core developer Sean Bowe tweeted that the Ironwood upgrade will be deployed to the testnet tomorrow. He also stated that the Ironwood upgrade will be activated on the mainnet around July 21st. All consensus rule changes have been implemented and have undergone a period of auditing. The specification/ZIP has been released and is nearing its final state. According to a previous Foresight News report, Zcash core developer Sean Bowe tweeted that Ironwood will introduce a new shielded pool using the Orchard protocol. Simultaneously, the Orchard circuit will add a flag controllable by consensus rules, which can disable payments to other users within the pool (while retaining change) as a privacy protection mechanism. After the upgrade, old Orchard pools will enable this restriction and prohibit fund transfers to old pools by constraining valueBalance.

ZODL CEO: The size of the Zcash shield pool has decreased to 30% in the past 48 hours.
According to Foresight News , Josh Swihart, founder and CEO of Zcash Open Development Lab (ZODL), tweeted that due to the FUD caused by the Zcash Orchard pool vulnerability, the size of the Zcash shielded pool has dropped to 30% in the past 48 hours.
ZODL founder and Zcash developers will hold a meeting in the coming weeks with the goal of "breaking down all barriers."
According to Foresight News , Josh Swihart, founder and CEO of the Zcash Open Development Lab (ZODL), tweeted that Zcash developers will hold a meeting in the coming weeks with the core goal of "Breach all gates." Meanwhile, the ZODL team released its weekly report, with key updates including the release of Zodl Mobile version 3.7.0 (enhancing network resilience, completing large-scale security hardening for Android, fixing multiple transaction status and sending bugs, and integrating the Maya DEX aggregator via Swapkit); and the release of Zallet version 0.1.0-alpha.4 (adding a Zebra state backend, several new RPC methods, and built-in encrypted identity commands).
Zcash's new privacy pool, Ironwood, will employ formal verification to eradicate undetectable proliferation vulnerabilities.
Mars Finance reports that the Zcash development team has announced plans to introduce formal verification through the upcoming new privacy pool, Ironwood, to eliminate the risk of "undetectable issuance vulnerabilities" through mathematical proof. Previously, it was reported that while the vulnerability in the Orchard shielding pool had been patched and there was no evidence of exploitation, the community decided to launch the new Ironwood shielding pool and conduct comprehensive formal verification of its protocol because it is theoretically impossible to confirm whether covert issuance has occurred through on-chain history.
