Kitabu Chain


This step assumes you have root access on a Debian or Ubuntu based host OS

$ apt get update
$ apt install chrony curl git
$ curl -fsSL | bash
$ curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
$ chmod +x /usr/local/bin/docker-compose

Validator node setup

1. Clone this repo

$ git clone
$ cd kitabu chain

2. Obtain your private key

If you have an existing keystore file, rename it to key else create a new one:

$ openethereum account new --base-path=$(pwd)
$ mv keys/ethereum/UTC* ./key
$ rm -rf keys

Save the password of the key created above in a password file. Save the key's public address for the next step.

3. Setup environmental variables and other configs

cp .env.example .env

Edit the .env file:

  • EXT_IP: Your server's external IP (curl
  • ACCOUNT: Your private key's public address

Edit docker-compose.yml or kitabu.toml to tweak the Openethereum config as per your own preferences.

4. Start the validator node

$ docker-compose up
#  or...
$ docker-compose up -d

5. Reverse proxy setup

The devops folder contains a Caddy config to use as a reverse proxy to further control access to your validator node's API.

Replace .yourdomain in the Caddyfile and point it to your server IP.
