Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Zcash developers have proposed an NU8 network upgrade targeting late January 2027, featuring the launch of a Tachyon privacy pool, an increase in the block size cap from 2 MB to 8 MB, and the introduction of SPHINCS-based quantum-resistant transparent transaction opcodes. The plan also adds scalable transaction formats, adjusts NSM redistribution timing, and sets a cutoff for new Sapling privacy pool deposits while preserving transactions and withdrawals. Developers estimate that combining Tachyon with the block size increase could push private transaction throughput to 200 per second and strengthen the network's quantum resistance. The proposal remains in community discussion, with final scope and timing not yet fixed.
