How to implement a Bitcoin like system which works only within intranet ?

(This system should not affect or be affected by the original Bitcoin network outside)

What changes need to be done ?
Any references ?

not a problem ... use a bitcoin core in server mode (main miner) and use a bitcoin miner (USB key = 333MH/s).

I'm no expert, but it seems to me this should work as long as any transactions in or out of the system (to or from the outside world) are somehow imported and exported to an online computer. I guess I'm not sure what the use of this would be, but maybe I am misunderstanding.

EDIT: Although I don't know how you'd get your transactions confirmed.

Why would you need a decentralized system at all if you are only going to use it in an intranet? A centralised ledger should do the work!

What your asking about is essentially creating an Altcoin using the Bitcoin source code. All you need to do is: generate new Timestamps, epoch string,  Merklehash, mine genesis block. If you change these values in the main.cpp, Bitcoin will start a new chain on your intranet. Just have one bitcoind compile run as Listen and have the other nodes connect to it. Its easy to create and mine a coin on LAN.

FYI, the guides are a bit out of date, you cant even probably find the repos they talk about, but it should help too educate you enough to accomplish the system you describe.

Edit: Clarity

Maybe he wants to make some tests about bitcoin, like simulating 51% attacks, simulating what would happen to transactions times when the has power is too high or too low, etc...

Why exactly do you need an intranet for this? Just create a copy paste coin and don't give anyone else the software. Boooom, own little network, works like intranet.

Maybe he/she wants to set up a closed system of currency for a family, company, or group. I can think of a bunch of reasons why having a closed system of currency could be useful to a group of people.

If I had read the title fully I wouldn't have made my useless contribution. My apologies.

I've thought about doing this before. I'd still like to but I don't know how to customize it.

Yeah, but to achive this, you will need a 100% closed network, and even then it doesn't really make much sence. Will they use company hardware to mine and compete for the coins? Hardly an optimal solution for company resources.
But what do I know..

With few miners on the network, difficulty would be far lower. They could also be premined depending on his/her needs.

true, but people would be inclined to try to increase their share by bringing USB asics ect to work and use company electricity. Not saying it can't work. Just saying that I don't get the economical reason for it.

What could work would be a 100% POS coin that is disctirbuted by CEO and has some kind of worth, like workfree days and shit.
