I'll test this ASAP! I REALLY need this feature (blockchain server <-> wallet client). I just want ask you some things... 1- How close is Libcoin with original Bitcoin? I mean, the output is a little different, the bitcoind help output was disabled and, I'm afraid that Libcoin can possibly being distant from Bitcoin in the future... That can happen?! 2- Do you have plans to update Libcoin on every new upstream Bitcoin release? How fast will be this updates? Do you need more resources/people working on it? Another questions not involved directly with Libcoin/Bitcoin but, I'll need it for my future Bitcoin projects, and Libcoin is on my radar: 1- Do you know about Diaspora* Project? 2- Do you have skills in Ruby on Rails development?

Hi Martin,

There are a couple of options of doing similarly...

In the libcoin repository you will find some code for btc and btcd, it is s= ome code I wrote a while ago and it needs to be updated. It functions as a = bitcoind master and slave. The btcd keeps the blockchain, but no wallet. bt= c keeps the wallet and contact the btcd to get transaction info (like send = an address and get its transactions or send a transaction id and get its de= tails). It works (or worked when I wrote them) with the wallet.dat, but nee= ds a little update.

You could e.g. run one btcd on the machine and several btc instances to get= the functionality you asked for.

Further, btcd also enables a web wallet, where the private keys are stored = in your browsers local-store.

I will get the application updated, but most likely in a bit other setup as= it is something I intend to marketize in the near future.

Hope this answers your question.

Cheers,

Michael
