Zcash community member ValarDragon proposed a NU8 network upgrade plan on the official forum, suggesting implementation in January 2027. Key features include the introduction of the Tachyon shielding pool, expanded transaction formats, an increase in the maximum block size from 2MB to 8MB, and the addition of transparent transaction opcodes supporting post-quantum cryptography.
Other proposals include adjusting the NSM redistribution date, determining the date when Sapling will stop accepting new deposits, and removing the Consensus Branch ID to improve wallet compatibility.
With Tachyon combined with larger block capacity, a shielded transaction processing capacity of approximately 200 TPS is expected. Post-quantum transparent transaction functionality will introduce 128-bit and 192-bit security level schemes based on SPHINCS. The above are currently proposals from community members, and their implementation depends on subsequent discussions and voting.
