Zcash Activates Ironwood Upgrade, Launching New Shielded Pool at Block 3,428,143

Zcash mainnet activates Ironwood NU6.3, introducing a new shielded pool to enhance security and enable independent verification of ZEC circulating supply.

Woofun AI reports that the Zcash mainnet has activated the Ironwood NU6.3 upgrade at block height 3,428,143. This update introduces a new shielded pool designed to improve network security and facilitate the independent verification of the ZEC circulating supply.

The original Orchard pool is now restricted, preventing new funds from entering. Existing Orchard funds must migrate through a turnstile mechanism before re-entering Ironwood, ensuring protocol-level guarantees that expenditures do not exceed verifiable income. Ironwood utilizes a formally verified and independently audited protocol to mitigate risks associated with previous Orchard vulnerabilities. Compatible wallets, such as Zodl 3.8.0, provide migration paths allowing users to transfer funds without changing addresses.
