Hi everybody,
What i really don't like about bitcoin is the waste of computing power (= waste of resources) it needs to secure the network, and how things would get worse the more bitcoin becomes successful.

Because of this I was wandering which are, actually, alternative mining alghoritms that you are aware of, and possibly their pros/cons.
I'd mantain such list in this OP and maybe group them up in a website if it could be useful, and discuss about mining alghoritms here to maybe come out with a new greener mining alghoritm or best block generation approach

If a post like this already exists (or website links) then please point me to it
thanks
