Zcash's formal verification efforts have eliminated undetectable counterfeiting bugs from the new Ironwood pool, ruling out such vulnerabilities up to the underlying cryptographic assumptions, as part of Project Tachyon.
Zcash testnet is updating for Ironwood with two independently developed consensus implementations, one by Valar Group (in audit) and another by the Zcash Foundation. Users can try a desktop wallet fork with migration code, and Keystone dev device users can update firmware to test signing 11+ transactions with a single QR code.
