So why do miners need to mine the 9 minutes after the last block was found? It's not necessary. Problem: How to prevent "pre-mining" in the 9 minutes time window? Possible ideas for discussion: - (maybe most difficult) global network timer sending a salted hash time code after 9 minutes. this enables validation by nodes. - (easy attempt) mining jobs before 9 minutes have a 10 (or 100 or just high enough) times higher difficulty. so everyone can mine any time but before to 9 minutes are up there will be a too high downside. It is more efficient to wait then paying high bills. The bitcoin will get a "puls". I dont think I see all problems behind these ideas but if there is a working solution to do so then the energy fud will find it's end. Saving energy without loosing rosbustness. :)
