Thanks, Eleftheria. I will try contacting support.

Thanks, Hamza. Yes, for sure, PoW is relatively old technology and PoS or Solana's PoH totally debunks it. Will write about them too soon.

Thanks, Eleftheria Batsou , I've just started writing blogs, this means a lot. Also, I've updated the Twitter URL but this is some problem from the side of hashnode. You can find me on Twitter here: 0xSarthak

Thanks for clearing this. Obviously, it's very energy-consuming. I missed that. Updated.
