By the way, just for reference the block in the main chain with the lowest difficulty is:
Block with the lowest difficulty:
Block Num: 125552
Block Hash: 00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d
Equiv Difficulty: 35,987,768,035
Equiv Diff bits: 67.07
That block would've been valid even if the network difficulty was 35,900,000,000 (yes, billion
), even though the actual difficulty was 244,000.
That may seem ludicrous, but it's actually on par with the approximately 2^68 hashes that the network has done up until now. The last part of it (the 67.07) says that if you were to do 2^67.07 hashes, you'd have a 50% chance of finding a hash just as good...
