We just published an article about using a multi-signature wallet with Coinkite where one of the keys are generated by you on your side. It is available here.

We just published an article with code modifying BitPay's Copay to use its multi-sig wallets on a server. We consolidated the connections established by different wallets into a single one for communicating with other copayers.

If you are using bitcoind the getnewaddress command returns you a new one.

If you want to speed up this process you can pregenerate addresses using keypool in the bitcoin.conf or passing the keypool option to bitcoind with the number of addresses to be pregenerated.

The point of this code modification is to run Copay on a server and handle wallets there. If you try to do this only with Copay the solution will not scale because the number of connections to the Insight server depend on the number of wallets being used.

I just published a way to do this using Copay.

I hope it helps.

Hi,

We just published a blog post about using Copay on a server to host multiple wallets and have them updated. This is useful if you like to implement multiple online wallets hosted on a server like BitGo. The github fork is here. The current version supports only 1-1 wallets but soon we will update the project to support multi-signature wallets and communicating them using the Insight mailbox plugin. Currently, every Copay wallet establishes a connection to the Insight server so it's difficult to scale if you have all the wallets in a server.

Hope it helps,

I can't see any reference on connecting bitcoinjs-lib / bip32-wallet with the bitcoin core, only examples using helloblock.io via a blockchain api that uses a third party service.

Do you know of any ~complete example?

Thanks

I always have someone in my team that knows what he is doing. Anyway, the main question was about a bitcoin implementation that can handle multiple accounts.

I wonder why nobody suggested Copay, BitcoinJS-Lib, or a fork of BTCWallet handling multiple accounts.

I am developing a virtual bank using bitcoins using the reference client multiple accounts capability. My main concern is scaling it to hundreds of thousands of accounts and transactions fired all the time.

What are other alternatives to this approach? I read that using multiple address assigned to different users is one way to handle it but would like to hear your opinion about other alternatives.

Thanks,
