asnwer to all why is there exist faster blocks

there was no difficulty retargeting for the first 576 blocks, they are needed for LWMA to work correctly as the window it looks at to control diff, and we decided to allow people to mine these blocks rather than mine them themselves, since even with powlimit diff it could take a lot of time and could be regarded as a premine...

you can see in the block explorer that the difficulty started changing from block 577

code lines to see where it is..

Param windows of lwma 576 by recomendation of diff algo cretator for keep stable diff.
