To update a client (i decided to change the difficulty retarget time), i added a checkpoint, is there another thing to do ?
boost::assign::map_list_of // Yo dawg, this is the secret. Checkpoint 0 hash == Genesis block hash.
( 0, uint256("0x68f6283d61e7f8b6ae0965d8873743197c72e5f54a447c9977d714cfa45b5d9c"))
( 15350, uint256("0x03d3fcdb7fb61543dad51002f15d689d88dd5f1debb8cc4c176a9e7adebe1f57"))
;
Did i forget something for the update ?
Thank you
