Zcash target interval proposed to change from 25 seconds to 20 seconds... shielding limit per block to four-fifths

Zcash developers have proposed cutting the network's target block interval from 25 seconds to 20 seconds, submitting the change to the community forum on the 8th for inclusion in a future NU7.1 upgrade and a forthcoming community vote. The proposal follows Zcash's NU7 activation on the 6th, which already reduced the target interval from 75 seconds to 25 seconds as specified in ZIP 259. The developers also propose lowering the per-block shielded transaction limit to four-fifths of its current level. If adopted, the shorter interval could reduce the time before a transaction is first included in a block, though no change has been applied yet. The move matters because it signals continued tuning of Zcash's throughput and privacy capacity parameters after the major NU7 upgrade. What to watch next is whether the community vote advances the proposal and whether it is ultimately bundled into NU7.1.
