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.
Just checked github and the fork block just changed to 642000, so we will have to wait 4000 extra blocks before PoW difficulty is fixed.
