Been watching $ZEC take a beating from FUD today after a nasty bug turned up in the Orchard shielded pool. It potentially opened the door to double spends, which is about the worst thing that can happen in a privacy coin.
The team moved quickly though, rolling out emergency patches and getting it locked down. The wild part is this vulnerability had apparently been sitting there for around four years without anyone catching it until now.
No one can say for sure if it was ever exploited. Devs insist there is zero evidence of foul play and on-chain supply checks out clean, but in crypto that kind of uncertainty is pure gasoline. Crypto Twitter is already spinning every angle possible.
