Proof of work will not succeed in the long run. I think we'll be moving to a proof of stake currency instead.

Examples are peercoin and Nxt.

Could you briefly explain/outline proof-of-stake in a nutshell ?

I read the wikipedia page but i am not 100% i really understood it correctly.

Proof of stake systems have not solved the distributed consensus problem. Peercoin is centralised and Nxt doesn't solve the problem.
