HOW-TO - Update Checkpoint

If you are the manager of one coin, you need to update checkpoint.
This is important so that nobody mess with your wallet and fork it to get coin back.

You should update your wallet every month (or every x block)
I decided to update it every 100 000 block for now.

If you are a POS coin you need to update checkpoint and pos checkpoint.

Before adding checkpoint, don't forget to check the hash on multiple wallet to be sure there is no fork.

First checkpoint.

Go on src/checkpoint.cpp
and update the static MapCheckpoints mapCheckpoints =

Just add the hash of the block.
(300000, uint256("0x0000000176cccf5d52740533848d18f1d352ef03b4351e323c20e8753949de26"))

POS Checkpoint

This is in src/kernel.cpp
do getblockhash (#block)
getblock (hash)

and get the modifierchecksum

Now add it
( 500000, 0x683d6393 )

If you have any suggestion let me know.
