🚨 $16 million in ZEC, private keys still in hand, but it can’t be spent anymore

Sprout, Zcash’s oldest privacy pool, is about to be sealed off.
On Thursday morning, 12,226 ZEC remained in the pool, down from 22,263 a week earlier. Most of it left on Sunday—about 9,094 ZEC. Only 40 ZEC moved on Wednesday.
The reason isn’t a hack. It’s an upgrade.
Network upgrade NU7 is set to activate at block 3,543,405. At 05:24 UTC on Thursday, the chain was still at block 3,542,391. At 75 seconds per block, that meant about 21 hours to go, putting activation at around 9:30 p.m. Thursday Eastern Time.
After NU7, v4 transactions will be rejected—and v4 is the only transaction format that can spend Sprout funds. In other words, the money in the pool will be inaccessible, even if you have the private keys.
At $1,300 per coin, those remaining funds are worth about $16 million. ZIP 2003 leaves the door open a crack: a future upgrade might restore access, but it also explicitly says that “it may never be reopened.”
If you still have an old wallet, you might want to check it: Sprout addresses all start with “zc.” If there’s a balance, you’ll need to move it before the upgrade.
One more thing: NU7 also cuts block times from 75 seconds to 25 seconds, tripling confirmation speed.
What’s really worth paying attention to isn’t “privacy coins freezing assets,” but the trade-off this system is making: to shed the security burden of old code, it’s willing to let some funds sleep forever.
That’s the double-edged nature of privacy coins—they make transactions invisible, but they can also quietly shut down an entire pool.
Do you think this approach—“freeze funds rather than keep old code”—is worth it? Let’s talk in the comments 👇
