Bitcoin with Raspberry Pi

I've seen a few people with electrum running on their Pi's. Bitcoind is just not going to cut it for a Pi.

I still don't understand..... Why not just store the datadir and swap on a thumb drive or on an external usb drive (w powered hub)? Isn't the solution really that simple?

Sure you could, but that would require a few days to sync and a dozen steps to get working. Would probably run pretty poorly too.

Can confirm Electrum works fine, although slowly - creating a transaction may take tens of seconds depending on number of inputs. What's interesting, under PyPy interpreter it runs even slower (commandline only, PyQt won't work with PyPy).

Swap is not necessary, but I'm using zram (swapping to compressed memory). Aside from saving sd card also prevents accidental write of sensitive data there. To enable it, you have to keep original raspbian kernel, not install from rpi-update.

I'm thinking about running a full node on Raspberry Pi with a web interface that looks like blockchain or Coinbase so that you could have a 'home server' that was secure and that supported the network. With so many thin clients running we're really losing a lot of Nodes.

It plainly won't work on Pi. Even if it would sync eventually, it would be so slow that it'd provide no added value to your nor to the network. Just stop dreaming and build yourself $150 celeron miniitx system + some > 100GB HDD from drawer. It would also easily support additional p2p goodies you'll want to try some other day.

For example I'm using this one as all-in-one bitcoind, electrum server, litecoind, freenet, home router, print server, anything: http://www.mini-itx.com/store/~GA-C847N

Are there updated instructions on how to run bitcoind on a Raspberry Pi? I'm trying to get the latest bitcoind working (0.86), and it requires different installation steps to what is in this thread.

I've fudged my way through, and now need to install Berkeley DB 4.8... unsure how to proceed.

Also, how do you store the blockchain on a different directory to the default?

The issue is that the master doesn't have the .unix file in src anymore.
So, download the 0.8.6.zip file.

> sudo apt-get install libboost1.50-dev libboost-filesystem1.50-dev libboost-system1.50-dev libboost-program-options1.50-dev libboost-thread1.50-dev libcurl4-openssl-dev libdb5.3++-dev libminiupnpc-dev
> wget https://github.com/bitcoin/bitcoin/archive/0.8.6.zip
> unzip 0.8.6.zip
> cd bitcoin-0.8.6/src
> make -f makefile.unix bitcoind

Anyone tried bitcoind on a Raspberry Pi 2?

Anyone tried bitcoind on a Raspberry Pi 2?

It should work as usual, the only issue its the ram once again, and I'm not sure if the compilation process takes in fact that its a quadcore processor now instead of a single core for b+.

[rupy]

Ok, so 1 GB not enough!

I documented how to do it here https://github.com/bitcoinbrisbane/10000nodes

I've started a project called 10,000 node project.  www.10000nodes.com to do just that.  PM if your interested in helping.

I don't think there is only 7.000 nodes, do you mean open nodes with port 8333 accessible?

hi there,

may be the following start script can someone help to start and run a bitcoind (0.10.x) on a RPi 1 Model B(+) (512MB RAM)

/usr/local/bin/bitcoind -datadir=/opt/bitcoin -dns -noupnp -maxconnections=10 -timeout=5000 -noirc -gen=0 -maxorphantx=25 -maxorphanblocks=25 -server -rpcuser=user-rpcpassword=mypass -rpcallowip=192.168.1.0/255.255.255.0 -rpcbind=192.168.1.1 -rpcport=8332 -dbcache=25 -daemon -checkblocks=25 -maxreceivebuffer=1250 -maxsendbuffer=250 -disablewallet

hi there,

/usr/local/bin/bitcoind .... -maxconnections=10 ....

This is a very low value for connections.

The shortage on the network is mostly peers that accept incoming connections.  If you run a peer, then you use up 8 of those slots.

With 10 connections, you only have 2 left for incoming connections.

A 16 connection limit means that you use up 8 slots but give back 8 slots.  This means that you are helping as much as you are consuming.

24 connections would mean that you consume 8 and give back 16, so you are helping the system.

thank you for your comment.
i will try to run the RPi 1 bitcoin node with 16 connections.

[pazor_true]

i have tried and it (RPi 1 B(+)) works fine with 16 connections.
