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)?
In my opinion, Solana is superior to Polygon not because of who is cheaper, but Solana is more advanced with block time even though many use the Polygon network because of cheaper transaction fees. In terms of speed, Ethereum is better, but because gas costs are too high, many projects are switching to other things.
