We’re in Phase 1 and almost into Phase 2. Some pools are allowing farmers to plot to them on mainnet using the Phase 1 plots. Obviously farmer beware as these plots will likely be changed in the future and you’ll need to replot again!
Today is phase 2 launch.
Chia will not have its own official Pool.
1.2 “may” launch this week, if no major problems are encountered. Bets are on for after July 4th weekend.
