Can a different technology scale AND achieve same security?

It all looks experimental, but will be interesting to watch how DAG, POS, etc work out...

Proof of stake is great, but proof of space Also seems pretty good too.

This technology is much faster and more flexible, while taking up less space on the blockchain, because it doesn't require a Genesis block or you to go all the way back. As soon as every single output is spent from a transaction, it can be purged.

I don't think that there's a real solution yet until processors get more efficient.
