Zcash Community Proposes NU8 Upgrade Plan, Aims to Increase Block Limit to 8 MB and Introduce Quantum-Resistant Technology

As reported by TechFlow on November 10, according to the Zcash community governance forum, developer ValarDragon has proposed an initial plan for the NU8 network upgrade, targeting implementation in late January 2027. Key items include launching the Tachyon privacy pool, increasing the maximum block size from 2 MB to 8 MB, and introducing SPHINCS-based quantum-resistant transparent transaction opcodes.

The proposal also plans to add scalable transaction formats, adjust NSM redistribution timing, and clarify the date when the Sapling privacy pool will stop accepting new deposits, while retaining transaction and withdrawal functionality.

The developer stated that combining Tachyon with block capacity expansion is expected to enable private transaction throughput of 200 transactions per second and further strengthen the network's quantum-resistant capabilities. The relevant upgrades remain in the community discussion phase, and the specific implementation details and timeline have not been finalized.
