According to "Once the blockchain is initialized,these parameters cannot be changed."
any detial document can improve us to make a good decision to initial the setting is good for any
special project ? if we have built a blockchain system after a period of time, we think that some
setting need to change, which parameter can adjustment, which can't?? or all the params.dat can't
change?
In above case, if everything can't change, we just delete all files that we created then re-run it can
re-build a new system and use the same chain name us the above case??
