Title: Bitcoin Core in multi user environment Post by: ForgottenPassword on January 10, 2015, 03:18:08 PM On linux, Bitcoin Core stores the blockchain and wallet files in the users home folder (~/.bitcoin). This is bad because if you have multiple users using Bitcoin Core, you'll have a copy of the blockchain in each users home folder, when you only need 1 copy.
I'd like to store the blockchain outside of the home folders, but keep the wallet files inside the home folders. What is the best way to do this?

Then several instances of BC will try to write to the same files at the same time. I don't think there's a straightforward solution to this.

Plus I assumed it's just a home pc with multiple users but only one accessing the machine at any given time.

See:https://en.bitcoin.it/wiki/Running_Bitcoin#Command-line_arguments (https://en.bitcoin.it/wiki/Running_Bitcoin#Command-line_arguments) This doesn't let you store the wallets in the home folders, and the -wallet argument seems to only let you specify wallets inside the data dir.

In a multi machine environment you could use a single machine running bitcoin core and the others connecting to it using mSIGNA[1].

If it's a desktop or laptop shared by a family, it's impossible that two people are using it at the same time. Switching accounts may leave programs open, but (as far as I know) they get suspended and should not conflict with others. If it's a server (maybe like an online wallet), then definitely many people can use it, but in that case you should have a single program (other than Bitcoin Core) managing all accounts.

It depends on the OS and settings. In a Unix based multiuser environment (eg OS X) nothing get suspended. Likewise you can have two people using the machine via screen sharing for example. :-) Title: Re: Bitcoin Core in multi user environment Post by: btchris on January 12, 2015, 05:53:25 PM You could and I don't know for sure but I'd start with trying symbolic links from the ~/home to the public folder you want to use.

I think shorena's option of running a single Bitcoin Core instance w/o a wallet and then configuring mSIGNA or Multibit clients to connect to localhost is probably the best option. |
