It was patched immediately, and Ironwood was proposed to make ZEC's supply auditable without exposing individual transactions. — [Shielded Labs](https://shieldedlabs.net/the-orchard-counterfeiting-vulnerability/)

+**"When I say 'formally verified quantum resistant infinitely scalable thermodynamic private unstoppable money' instead of 'Zcash'"** — a deadpan post from genzcash poking fun at how dense Zcash's technical pitch can sound compared to just saying its name, posted right in the middle of the Ironwood migration news cycle.
