bitcoinj - running support node

[allgoodthings1]

I read that MultiBit uses bitcoinj.  Is that something we can support by running a full node somehow -- like we do the regular bitcoin blockchain by running bitcoind or the newer btcd?

I'm just looking to put to good use all the computers I have, doing all the support I can for the network.

Although bitcoinj has a full node option, I don't think MultiBit can be configured to use it (I could be wrong though).

You can run bitcoind or btcd on the same machine (or on another) and then force MultiBit to connect to it and only it. This gives you the benefit of using full height-based transaction validation. To do so, locate your multibit.properties file (in the %AppData%\MultiBit folder on Windows) and add this (it's just a text file):

Code:

singleNodeConnection=127.0.0.1

(or some other IP or DNS name)

Yes by running a regular full node you are contributing resources that bitcoinj based wallets will use (along with other SPV wallets like BreadWallet)
