1Zcash activated its NU7 network upgrade at block 3,543,405.
2The upgrade rendered approximately 12,224 ZEC in the legacy Sprout shielded pool unspendable.
3The blocked funds amount to roughly $15 million, though they have not been permanently burned.
4A future network upgrade could potentially restore access to these stranded funds.
5NU7 also shortens the target block time and introduces a new fee handling mechanism.
