The OriginTrail Decentralized Network was designed for scalability and enables anyone to run a node. You can find all the resources and instructions for the node setup on the mainnet here.
The recommended minimum specifications are 1CPU, and 2GB RAM with at least 10GB of storage space.
Before setting up a node, you must own a valid Ethereum wallet with at least 1000 TRAC tokens and at least 0.05 Ethers. These funds enable your node to connect to the network and register its profile. For normal node activity, you should have a bit more funds in ETH so that your node can pay for transactions.
A public IP address, domain name, or open network communication with the Internet is required. If behind NAT, please manually setup port forwarding to all the node’s ports.
The host machine needs to have Docker installed to be able to run the Docker commands specified below. You can find instructions on how to install Docker here:For Mac https://docs.docker.com/docker-for-mac/install/
It is strongly suggested to use the latest official version.
By default Docker container will use 8900, 5278 and 3000 ports. These can be mapped differently in Docker container initialization command. Make sure they’re not blocked by firewall and open to the public.
Please note: port 8900 is used for REST access which is not available until OT node is fully started. This can be concluded after following log message is displayed.
info - OT Node started
To properly configure the node you will need to create a config file in JSON format and provide some basic information about how the node should work. This file will then be passed to the Docker container.
Let’s create the file .origintrail_noderc and store all the information about what kind of configuration we want to set up. The bare minimum of settings that needs to be provided is a valid Ethereum wallet and public address or domain name.
We create the .origintrail_noderc file with following content:
"node_wallet": "your wallet address here",
"node_private_key": "your wallet's private key here",
"management_wallet": "your management wallet public key here",
"hostname": "your external IP or domain name here",
"remoteWhitelist": [ "IP or host of the machine that is requesting the import", "127.0.0.1"]
"rpc_server_url": "url to your RPC server i.e. Infura or own Geth"
You can find more detailed wallets explanation here
(DISCLAIMER: Your private key is needed for the node operational wallet to be able to sign transactions to the blockchain. The node management wallet takes care of your rewards and its private key is not stored on the node. The operational wallet private key is not in any way sent to the OriginTrail team or stored in any other location, other than this config file and locations you decide to keep it. Please, be aware that you are required to keep all your keys and node safe, and that the OriginTrail team does not have any ability to help you recover the private key if lost).
Everything is prepared for the Docker to create and run a container. Let’s just point Docker to the right image and configuration file with the following command:
sudo docker run -i --name=otnode -p 8900:8900 -p 5278:5278 -p 3000:3000 -v ~/.origintrail_noderc:/ot-node/.origintrail_noderc quay.io/origintrail/otnode-mariner:release_mariner
NOTE: in this example, our configuration file .origintrail_noderc is placed in to the home folder of the current user (ie. /home/ubuntu).
To check if your node is running in Terminal, run the following command: docker ps
This command will indicate if your node is running.
1 - docker start otnode This command will start your node as a background process.
2 - docker start -i otnode This command will start your node in interactive mode and you will see the node’s process written in the terminal, but this command will not run your node as a background process, which means your node will stop if you close your Terminal/Console.
Note: By using this command, you will be able to see your Houston password in the terminal.
1 - If you started your node with the docker start otnode command and you wish to stop it from running, use the following command in your terminal: docker stop otnode
2 - If you started your node by using the docker start -i otnode command, you can stop it either by closing the Terminal or simply by pressing the ctrl + c.
If you prefer to manually install each piece of software needed to run an ODN node, you can find detailed instructions in our technical documentation: OriginTrail Documentation
