Node Configuration

Environment

Demos nodes use a .env file and a few additional configuration files to provide a customizable and replicable setup. For convenience, a precompiled .env file is already included.

In most cases, you won't need to edit it — just double-check that the listed ports are free on your system. Besides the ones listed, Demos nodes also launch a Postgres Docker container that listens by default on port 5332 (you'll see how to change this in the next chapter).

Note: You don't need to configure the Twitter and GitHub sections of the .env yet, even if they are present depending on the branch.

Keys

To generate your initial keypair, simply run:

./run

The node will crash due to a missing peerlist (expected at this stage), but it will create a file named like publickey_1234567890 inside your node directory. Inside that file, you'll find your public key.

Peerlist

Demos nodes use a demos_peerlist.json file to define peers. First, create it by copying the example file:

cp demos_peerlist.example.json demos_peerlist.json

Then open it with your favorite text editor.

• Solo mode (local testing): Replace the identity key with your generated public key.

• Connecting to other nodes: Add lines in the following format:

  "1234567890...": "http://url:port"

Replace 1234567890... with the actual public key of the peer and http://url:port with its URL.
