Farming using the Spacefarmer Community Node

Farming can be quite a struggle when running a full node with low specs. Chia allows many architectures, which makes it possible to (trustlessly) connect your farmer to a remote node. In this guide we will tell you why and how you would set this up.

Network Topology

The network structure looks like this:

                                                             _____  Harvester 1 (certificate A)
other network peers  ----Spacefarmers Community Node ---Farmer (CA) ------  Harvester 2 (certificate B)
       |                                                    \_____  
       |                                                            Harvester 3 (certificate C) 

The communication between the Community Node and your local Farmer is bi-directional; The Community Node feeds the farmer with it's mempool logic (we use the default mempool logic), and the Farmer asks the Community Node to propogate blocks to the rest of the network. As we allow only Spacefarmers to connect to the community node currently, incentizes are aligned to also actually propogate the blocks to the network.


As opposed to a seamingly similar set-up by another pool, the Spacefarmers Community Node does NOT sign your blocks, YOU do. As can be read in this criticism, any other way would not be to your advantage. An advantage to decentrality of running the Community Node is thus that netspace is more decentralized, as opposed to a farmer with low specs not joining the project at all. A downside is that this will not reflect in node-count.

Node Uptime

To ensure the highest possible uptime for the Community Node, we use a multi-node set-up behind a load balancer. This way, when we upgrade one of the nodes, you can rest assured that you will maintain a connection with a full-node without disruption of such processes.

How to connect

  • Chia 1.3.0 and up required. Find the latest version of Chia here
  • Make sure you stop all Chia processes by closing the GUI or chia stop all in the CLI
  • In the config.yaml, which is located in C:\Users\<yourusername\.chia\mainnet\config, you will have to change
        host: localhost
        port: 8444


        port: 8444
  • make sure you have connect_to_unknown_peers: false
  • If you use this node as a failsafe node to your main node, make sure to copy + paste the pool info: from the config.yaml, as well as add your keys and plots.
  • in CLI chia start farmer-only
  • chia start harvester

Are my keys safe?

As per Chia 1.3+, you can run your wallet without a full node. This makes it so that your wallet doesn't rely on your full node to sync, but instead uses the whole network. Your wallet won't use and won't trust our community node. Instead, wallets will switch to 'trustless mode' and do a p2p sync from the network for the wallet. Your keys are used to sign the blocks locally on your farmer. The Community Node is just used to propogate your blocks to the network. Also note that everything is implemented in run and is using the infrastructure hooks laid out by the Chia Company.
