You pick a block number and when the block is mined you take a snapshot of the block-chain
and then download the latest Bitcoin code from Github and make a few tweaks to the code to increase the
block-size and make changes to the block type.
Then you need 20 or so machines to host the new code (Not 20,000 like we have now)
and to make a few changes to the wallet software and away you go.
80% of the code is concerned with mining and is not for the benefit of the users
but it all like taking a copy of MS-DOS 3.2 and tweaking it to make Silly-Dos
because the whole thing is outdated and won't scale but it is a starting point
so good look to Segwit2x, Bitcoin Cash, Bitcoin Gold because they don't have
crazy high transaction costs like Bitcoin and maybe the development team is
on our side
Anyway if block chain is so good then how come lightning is being sold
on taking things off the block because they seem to me a contradiction
here and they are not being clear about the hubs that charge fees being
just another name for mini-banks
