Proof of Work
Thomas Hu from Vidtoo shared a few details of their upcoming ASIC in last week’s governance meeting. The professional grade is meant to be capable of 40-42 Graphs/s at 2800-3100W with 30 ASIC chips, and there’s a smaller consumer grade miner with a single ASIC chip at 100W roughly expected to mine at 1.40-1.33 Graphs/s. No release date yet.
In a new RFC, @tromp proposes that Grin’s Difficulty Adjustment Algorithm is changed to wtema, targeted for v5.0.0.
It’s now no longer possible to solve blocks with Cuckatoo31, all miners should now be mining Cuckatoo32 blocks, or the GPU-targeted Cuckarooz algorithm.
