Crypto is the digital coal of our times.
With the disadvantage of large stakeholders dominating the network and undermining the decentralization.
I don't defend anything - I simply do not consider the existing crypto assets as an alternative to currencies at all. They are still so far from being reliable or stable to be a good means of general exchange. They have their place in the area of investment and speculation and that works fine for me.
Primecoin wants to have a word having done useful PoW for over a decade.
Prime numbers are searched for doing the PoW. The blockchain essentially contains a data base with prime numbers. As far as I can tell Primecoin never was popular,.but I like the novel approach of doing things, when most cryptocurrencies of that time were lame copies.
Btw. the Primecoin creator made Peercoin, which was afaik the first (and apparently still running) network being secured by Proof-of-Stake.
Hybrid pow/pos has been worked on since the beginning. Peercoin is still alive.
