  1. FORKHEIGHT define

  2. fork genesis (if use the old genesis module, will remove this part verification, is it ok?) 2.1 create 2.2 verfication

  3. mining : task (3.1) if height < FORKHEIGHT: create new task after FORKHEIGHT height; (3.1.1) create task with parent (modified) (3.1.2) saveBlock (mined or sychronized) (3.2) if height > FORKHEIGHT: delete and reverse, and then back to step 3.1;

    (engine verification: verifyHeaderCommon and verifyHeader)

  4. sychronize (BE CAREFUL ABOUT THE DIFFICULTY!)

    (4.0) check the peer's fork gensis hash is right, if and only if yes, then

    (4.1) height > FORKHEIGHT and difficulty is bigger; GIVE FORKGENESIS A HIGHEST PRIORITY (4.1.1) first check FORKHEIGHT hash = FORKHEIGHT_HASH: if yes, node already start from fork, sync; if no, reverse and sync;
    (4.2) height < FORKHEIGTH Sync from FORKGENESIS, need to handle discrete database!

  5. p2p: peer selection: check the sync will delete peer. modify the case!

  6. new coinbase CAN NOT height before FORKHEIGHT
