Which blockchain has better block speed, lower cost, higher security and better road for scaling up (network running smoothly with more and more dapps being created on it)?
I think both network are okay. But solana is on different caliber and has advanced way too big compared to polygon. I am not saying matic isnt good but in terms of usage, I think there are too many solanians that outweight matic. But recently, solana had a very bad downfall since theit network stopped. So there still some negative point of view on their part. But for me both network are all good for investment.
that's why they need to upgrade to version 2, so that the things you fear don't happen again. it can affect their network image in the future, they must move quickly and precisely, so that there is a solution in the future and it doesn't happen again.
