Zcash (ZEC) activated its NU7 protocol upgrade on the public testnet on October 4, 2026, cutting target block spacing from 75 seconds to 25 seconds. The Bitcoin Foundation reported that the change is being tested before a planned mainnet decision.

NU7 tests 25-second blocks and legacy transactions

The testnet activation occurred at block 4,465,026 on October 4, 2026. The upgrade also introduces a network sustainability mechanism and changes transaction rules, according to the Bitcoin Foundation. Target block spacing describes the intended interval between blocks, while the public testnet is a rehearsal for the main Zcash network.

A 247 Wall St report published on October 19, 2026, said 22,309 ZEC in the legacy Sprout shielded pool could become unspendable if holders do not move the funds before mainnet activation. The report said the protocol change disables version 4 transactions, which are required for spending from that older pool.

ETF flows measure money entering or leaving exchange-traded funds that hold the underlying asset. The October 19, 2026, withdrawal and the October 15, 2026, figure are separate daily readings, according to TokenPost. They describe fund activity rather than the full market for ZEC.
