could you ldd the binary?

Not sure how widespread the problem is but I run Grin++ as node which since the last hardfork has some stability issues. Grin++ keeps crashing every so many hours. If others have the same issue, this might affect a large number of nodes which will not be online 24/7. @david knows about the problem but I think he also has other tasks to work on, e.g. for the Litecoin mimble wimble implementation.

The latest beta fixes those crashing issues, but I haven’t had time to thoroughly test and push the actual 1.1.4 release. https://github.com/GrinPlusPlus/GrinPlusPlus/releases/tag/v1.1.4-beta.4

EDIT: Litecoin’s first mimblewimble testnet is scheduled to go live the end of this month. Once it’s live, I’ll have a bit more time to focus on this release.


Possible logo to be engraved into the RPI4 any other ideas?

We created a room #Grin-Pi on the Grin Discord Server.

If requested we could also move discussion to Telegram or Keybase.

Can I successfully install and run GRIN node on RasPi 3?

You’ll likely need to create swap space in order to build but it should work

Anybody know what to do with this error I am getting when trying to compile the node?
pi@raspberrypi : /home $ sudo ~/.cargo/bin/cargo build --release

error: no override and no default toolchain set

rustup install stable
rustup default stable

Looks like it installed rust, but still no access.

pi@raspberrypi : /home $ rustup install stable

We are not yet fully ready with our auto-deployment and help you with your installation problems. But you could start having a look at : https://github.com/MCM-Mike/Grin-Pi/blob/master/doc/puppet.md

First rendered pictures of our final design are beeing uploaded.

thanks for this, I tried the official instructions but I had compile errors in rust after I had installed rust from apt get. After I apt remove rust and installed from rustup.rs, it works!

I installed it on my raspberry pi 4/4Gb, with the chain data on a ssd. It works alongside a Bitcoin Core node and started syncing. The pi is still usable as a desktop, but I am thinking of getting a second pi :slight_smile:


Hi. I’m new. Are these for sale? Or build your own? How much do they make?

Hi @Slydoggrx, these will probably go on sale at the end of this year. The design of the casing is however just open source, so you can also print it yourself, buy a raspberry Pi and install the software.

A node earns nothing. Grin does not use a secure or master node system (in which case you secure the network by staking), so a node is just there to strengthen and validate the network and for you to validate your transactions if you install it together with the grin-wallet (rust implementation), so you can have your wallet on the Raspberry Pi.

If you want to earn Grin, the best way is to mine yourself using a G1 Mini miner from Ipollo, they are sold via Nhash, see this link for more information:

Be ready so shelf out some money though, they are 900$ or so.

Running a node earn nothing, unlike mining. As a fan of any coins, we normally run one-two nodes to support that blockchain network.
Personally I run 4-5 Grin nodes just for fun.


Hello, I followed your tutorial to make a node on Raspberry 4

it seems that I have problems of RAM memory and can not pass the step 3/7 of synchronization

I have a Raspberry 4, 4go ram, does an 8go solve the problem ?
or a swap-file ? I don’t know why I can’t use it for the moment. (swap-file still free).

I get this error : TxHashSetErr: Cannot allocate memory.


We are using the 8GB RAM RPI4 , this should solve your problem.
Swap file is not as important as the RAM, I would adjust the SWAP file once you have your system running.
