Several questions for a web service based on Electrum

[Polux44]

Hello guys!

I want to develop a web game based on Electrum.
Users can spent the number of bitcoins they want for having an "internal" coin usable in this game

I want to use electrum on the server in watch only mode, for generating 1 address per user.
Idealy each time a user does a deposit,  the system detects it and increase his "internal" coin wallet.

- If I understand well, if I run Electrum with the main secret phrase I will be able to also see all secondary addresses generated for users. It is only dependent to the gap limit. Am I right?

- Can we control created addresses in another way than gap limit? I'm expecting that several users will record on the website without deposit anything (because they would be not interested on the game, finally). So the risk would be to have more "fake" users than the gap limit allows it. I would appreciate something like "give me 1 new adress" method.

- I saw a script merchant.py which is not focused on my workflow but which could be a good base for it. Because it works a daemon, does it mean we do not need qt4 libs for this? (no GUI). In fact I don't know how qt would behave on a server without graphical interfaces.
A question around it is: can we use electrum purely in a shell?

- How can we help the electrum network? There is a network fee, but is there any "electrum network fee"?

Thanks,
Polux

sorry but the merchant script is broken in the current release.
I am trying to fix it asap but I really have lots of things to do, so don't expect it too soon..

You can generate addresses even now. You don't need to have electrum running. There is some code here:

But to learn about coins you've received you have to have bitcoind or use blockchain.info's api. I suppose you could use electrum as well but you'd need to know python to fix that merchant script.

Electrum can be run over the command line. No gui required

Electrum 2.0 is going to feature a full featured daemon process for servers:

There is no electrum network fee but if you want to support the electrum servers you can donate to them. You'll find their address on the console tab in the Electrum window.

Thanks for this complete answer!
And very very intersting post concerning Electrum 2. Seems an exciting dev
