Difficulty retargets every block (exponentially) based on last 160 blocks
Can you explain this retarget?
Thanks
I'd imagine it's like this:
Block 1 took 2 seconds to find
Block 2 took 3 seconds to find
Block 3 took 4 seconds to find
Total: 9 seconds/3 blocks = average of 3 seconds. Retarget would be based on that (with 160 blocks instead of 3, obviously)
Current diff update: 36
