I will ask you differently, do you wanna take responsibility for angry users
who had their BTC wallets wiped clean by malware running on other computers on their network, because they
have typed "user" & "pass" into their bitcoin.conf, just like your software recommended.

I also considered the solution in which we generate a random long user + pass on startup,
but it's worth shit because it changes every startup and nobody will be arsed to change
it every time (in bitcoin.conf).

This is where using the BTC .cookie file makes sense, but the user still needs to provide the path in some way.

What we want is zero configuration. That will be possible by a middle man software. As follows:

1. user downloads bitcoin from bitcoin.org and starts it
2. user downloads a middle man software that don't exist today but will later (once we do it)
3. user downloads haircomb core
4. user starts all 3 programs above
5. haircomb core starts syncing no config needed.

this will be possible because:
1. haircomb core will request blocks from port 8332 (RPC PORT)
2. middle man SW that listens on port 8332 will redirect the requests to port 8333 where the Bitcoin
is already listening on the peer to peer network. (In the correct format). This is true by default
on Bitcoin core, without any configuration.
3. Bitcoin normally transmits the blocks to middleman (in a special format, NOT in JSON)
4. Middleman transits the required blocks to the comb core (in JSON)

I understand this, but I don't see how it'll be possible to completely eliminate the need for config files right now, before the middleware is developed.

What are the possible obstacles to this zero configuration? Huh

1. Bitcoin already running on 8332. The middle man will then fail to run. The middle man program
will recommend to delete both BTC and COMB config files.

2. Old version of comb ( the one we are developing right now) will fail to run without a config file!! (this problem needs to be solved RN)

3. Old version of comb recommending the wrong thing when config file have blank credentials or not found. It must not fail with error and it must keep connecting to the middle man with blank credentials despite of the credentials being blank.

4. Middleman software not being available (this will be solved soon)

5. Blank credentials not being testable - sure, not on BTC, but the fake block simulator will serve you something even with blank credentials.

The current version of COMB I have up does not require the config to run, only to access the BTC RPC. I'm not sure exactly what you're trying to convey here; if what you're saying is that the current version of COMB MUST be able to access the BTC and pull blocks without any sort of config file, then I'd love to hear how you think it could be done, because I don't see how to accomplish that. Unless you're suggesting a modification to the current program so that it DOESN'T use the RPC, and instead pulls over 8333 then converts to JSON, but that's just the middleware solution.

So again, I'm not 100% sure exactly what you're proposing the steps forwards are; accessing the BTC RPC requires authentication, either the user provides said authentication or they can't pull over the BTC RPC. We can either attempt to make the provision of the authentication easier, or circumvent the RPC via the P2P network. The most non-intrusive way to have the COMB client and the BTC client communicate is using the .cookie file, but COMB needs to know where that file will be. This means that a) the user will have to provide a path to their BTC data dir, via config file or some other means, or b) the user will have to place combfullui WITHIN the BTC data dir. We can set up either of these options, but you seem fairly adamant that COMB should not require a config file in the slightest, which just leaves the user dumping combfullui in the same directory as the .cookie file.

The reason that the BTC call fails with blank creds isn't anything hard coded into COMB; BTC just doesn't return a usable value. Right now the only time that COMB will say "Hey, put in credentials" is if it attempts to contact BTC and gets a bad response back.
