How did Solana get frozen twice in the last month?
If it ran on multiple nodes how did it stop working on all of them?
That's what happened, even if you look at IDO Solchick, at that time the Solana network was having problems and the developer was trying to do a reset because of the density of transactions.
Developers seem to continue to improve the network, but as you know, POW is better than POH or POS, because POW has a better level of security, so far I have never seen a POW system crash, but as you can see, they all have excellence, when you want transaction speed, then there is one thing that will happen in the future, namely traffic jams like Solana's.
