JetCash NU8 suggests 200 TPS potential... adds over 200 tokenized stocks

Zcash developer ValarDragon has proposed the NU8 upgrade, which would raise shielded transaction throughput to roughly 200 transactions per second by introducing a new shielded pool called Tarkion and expanding the maximum block size from 2MB to 8MB. The plan was posted to the community forum on the 9th, with the exact scope of changes to be settled through follow-up proposals and community discussion. The proposal matters because Zcash's privacy-preserving transactions have historically been constrained relative to transparent ones, and the combined pool-and-blocksize approach is the developer's basis for the 200 TPS estimate. What to watch next is how the community receives the Tarkion pool design and the fourfold block size increase, and whether subsequent proposals lock in those parameters.
