Zcash upgrade could freeze old ZEC in Sprout
BROBROK News · Based on reporting by Decrypt ·
Zcash’s NU7 upgrade will invalidate v4 transactions, making funds left in the Sprout privacy pool unspendable. The remaining balance is about 12,224 ZEC, worth roughly $15 million to $16 million at recent prices.
Key points
- About 12,224 ZEC remain in the original Sprout privacy pool.
- NU7 removes support for v4 transactions, which are needed to withdraw Sprout funds.
- The affected coins are frozen, not burned, according to ZecStats.
- The upgrade also shortens Zcash’s target block interval from 75 seconds to 25 seconds.
- Modern ZEC holders using supported wallets are not expected to be affected.
Why it matters
This is a protocol change that can strand legacy balances even when wallet keys still exist. It also shows how Zcash is removing older technology while improving network speed.
