ok now I am really confused.
Everybody says wait till block 638000 then POW starts again But i go to cryptocoders pool I see people mining.
So what about it? Somebody please explain what is this about. And why did POW stopped in the first place?
I've read a bit in the thread but can't follow it.
Thank you guys

Actually, the POW is not broken, just the pow difficulty is very-very high. for normal cpu/gpu, it is hard to find a pow block, but not impossible.
if they have a very good lucky, and found a 0000000000000000...... hash block. but they're runing the gpu for notting...
After 638000 block, diff calculation is fixed, and gpus can found block in normal speed.
