Single bitcoind instance and multiple wallets, is it possible ?

[Farghaly]

Is it possible to interact with multiple wallets using a single bitcoind instance ?
i know that the wallet on which bitcoind operate can be changed using -datadir option, but this is per bitcoind instance. is it possible to make somethig like this ? assuming there are multiple wallets

Code:

getnewaddress <account:Foo> <wallet:wallet1.dat>
listunspent <wallet:wallet5.dat>
keypoolrefill 100 <wallet:wallet7.dat>

not sure it works for your application, but you should have a look at btcd and btcwallet: they were built to accommodate just this scenario.

iirc bitcoind's account feature is deprecated and does not work how one would hope or expect.

You should read through this thread to get some insights on how to do it: http://thread.gmane.org/gmane.comp.bitcoin.devel/4009

Multiple wallets, used serially, works fine today.  I manage multiple wallets using symlink replacement.

I just use the account functionality to separate, but symlinks would work too (as mentioned above) and are also easy to set-up. Or perhaps look into using something like sx tools to perform the transactions through bitcoind rather than bitcoind itself.

There are a few reasons not use accounts, but mainly this one:

The accounts code does not scale up to thousands of accounts with tens of thousands of transactions, because by-account (and by-account-by-time) indices are not implemented. So many operations (like computing an account balance) require accessing every wallet transaction.

Personally I don't think libbitcoin/obelisk/sx is production ready, but I respect the work genjix is doing.
