Title: How to run a partial node connected to full node? Post by: d4n13 on June 19, 2015, 05:10:56 AM I have a full node running on my LAN, and would like to utilize it's work on other clients.
How to I get bitcoin core to run a partial node trusting my dedicated full node for blockchain queries (or has that not been invented yet)? Thx Title: Re: How to run a partial node connected to full node? Post by: d4n13 on June 19, 2015, 06:53:01 AM OK... looks like bitcoinj may be what I'm after. The WalletTemplate class looks perfectly sufficient.
There is some APIs that control the peer list, and looks to be a sample of building this list manually, which is what I'm after. I'll keep digging, but this is pretty "close-enough" for my windows and linux machines. Anyone else have a simpler answer, aka "bitcoin-qt.exe -partial -connect=10.10.10.50"? Thx Title: Re: How to run a partial node connected to full node? Post by: achow101 on June 19, 2015, 03:20:19 PM Bitcoin Core be default is a full node. You cannot change it to be a partial node without changing the code. In order to have a partial node, you need other software, such as something built on BitcoinJ (e.g. MultiBit) and you can specifically have it only connect to your Bitcoin Core full node.

Multibit.exe -connect=10.10.10.5 ? Title: Re: How to run a partial node connected to full node? Post by: achow101 on June 19, 2015, 04:14:58 PM open the file multibit.properties in %appdata%/Multibit
Add the line Code: peers=<peers to connect to> Title: Re: How to run a partial node connected to full node? Post by: d4n13 on June 19, 2015, 04:25:05 PM Shazam!!!
many many thanks. Didn't see the specification to the properties file, but I only just found the multibit github repo. You have a link to the full property specification? Title: Re: How to run a partial node connected to full node? Post by: achow101 on June 19, 2015, 04:53:01 PM here is what I found for the properties file: https://github.com/jim618/multibit/blob/master/configuration.md
It doesn't have everything about the properties file, but it does have the thing about peers. Title: Re: How to run a partial node connected to full node? Post by: d4n13 on June 19, 2015, 06:50:20 PM Thanks... to add to your research, that was for an older version of MultiBit.
New MultiBitHD uses "mbhd.yaml", but I think the process is similar. Still trying to document mbhd.yaml Title: Re: How to run a partial node connected to full node? Post by: tl121 on June 20, 2015, 06:49:26 PM I have run bitcoin core on a number of computers on my LAN that are configured (via the config file) to only talk to one front-facing bitcoind on a dedicated computer. I mostly did this for test purposes. The problem is that every time you turn on a a bitcoin node it has to catch up its copy of the block chain. This takes a while even going directly over a gigabit/second LAN connection. About the only benefit of running this way is that it eliminates extra traffic on my (slow) Internet connection.
Presently, I run an Electrum server on my dedicated bitcoin node. I run Electrum clients on several of my other computers and these access the dedicated node on demand. Electrum clients support Trezor, making providing convenient access to bitcoins secured by a hardware wallet. Title: Re: How to run a partial node connected to full node?
