Shielded Labs said exchanges, mining pools and wallets may need more time to complete Zcash’s Z3 software migration and safely prepare for Ironwood. Shielded Labs has raised the possibility of delaying Zcash's Ironwood network upgrade, warning that ecosystem participants like exchanges, mining pools and wallets may not have enough time to prepare their systems for the planned activation in late July.  Jason McGee, executive director of Shielded Labs, said in a Zcash community forum post that two major projects are moving forward at the same time. Alongside Ironwood, infrastructure providers are being asked to replace Zcash’s longstanding node and wallet software, zcashd, with a new collection of tools known as the Z3 stack. The concerns highlight the trade-off between quickly restoring confidence in Zcash’s shielded supply and giving ecosystem participants enough time to deploy and audit the new infrastructure safely.  Read more

The all-stock deal gives Fortitude a Nasdaq listing while HeartSciences retains its healthcare business and existing shareholders keep a minority stake.

Ironwood would close the old Orchard pool to new activity and route funds through a turnstile before they enter a new shielded pool. Zcash developers are proposing a new shielded pool called Ironwood after a recently patched bug raised concerns about whether counterfeit ZEC could have entered circulation unnoticed. The Zcash Open Development Lab (ZODL) said Saturday that it is working with Tachyon, Valar Group, the Zcash Foundation and Shielded Labs on the proposed network upgrade, which would add formal verification and independent audits to the Orchard protocol, a privacy system that lets users move ZEC without revealing transaction details. The proposal would close the current Orchard pool to new deposits and internal transactions, requiring funds to pass through a “turnstile,” which serves as an accounting checkpoint, before entering Ironwood.

Zcash developers are weighing a new shielded pool and turnstile accounting after the Orchard bug raised supply verification questions.

The group said the proposal is still subject to further explanation and community review. Shielded Labs said it plans to publish a follow-up post next week explaining how the upgrade would work and what tradeoffs it could involve.  Read more
