Congratulations to @kano, the block finder and all the PPLNS miners.
If I am not mistaken, the solo pool is relatively new. It started at the end of 2021. I don't think many people are aware of this fact and hence the low hashrate. The PPLNS pool was there since the begining.
The solo pool did mine a first block (block 706,643) when kano was testing it for reliability and he give it all away to the PPLNS pool miners!

Now let's see a solo pool block!
