Ethereum never faced network problems like what solana and harmony did. Solana team was claiming if it was due to blockchain being overloaded and how is it possible when they have claimed solana to be the most scalable blockchain. I do believe if there was something wrong with this blockchain. The truly decentralized blockchain never gets shutdown. I don't know why there are people who still call solana and one as a promising blockchain once the reality said the different thing. SOL is getting shutdown for a few times and this is what they have called this as the best blockchain for this time.
Truly centralized blockchain. 1k nodes were totally BS.
