Installation

What you need
To run an CIC blockchain non-validator node
Add non-validator node (mainnet)
1.Requirements: Linux: tested on Ubuntu and Debian.
description: Setup a non-validator node. To become a validator, node must get votes from at least 2/3 of current validators.
CIC Node Setup
Run the following Commands:
sudo apt update
Install screen:
sudo apt install screen
Setup Java:
sudo apt install default-jre default-jdk
Download latest CIC blockchain client Hyperledger Besu:
wget https://hyperledger.jfrog.io/artifactory/besu-binaries/besu/21.10.5/besu-21.10.5.zip
Install Unzip, if not already installed:
sudo apt install unzip
Unzip the file, and rename it for ease:
sudo unzip besu-21.10.5.zip; sudo mv besu-21.10.5 besu
Add environment so you can run CIC blockchain client from anywhere:
sudo nano ~/.bashrc
Add the following line to the end of the file. Make sure to put your username:
export PATH=/home/YOUR_USERNAME/besu/bin:$PATH
Relaod bashrc file:
source ~/.bashrc
Create a directory structure like this:
mkdir -p CIC blockchain /node01/data cd CIC blockchain
Create the genesis file, and paste the contents from the genesis file into it:
Genesis File: https://github.com/CIC blockchain /CIC blockchain -Documentation/blob/main/technology/genesis.json
sudo nano genesis.json ( Save using Ctrl + O , then exit with Ctrl + x )
create static-node.json file and paste the contents of static-nodes file into it:
Static-nodes: https://github.com/CIC blockchain /CIC blockchain -Documentation/blob/main/technology/static-nodes.json
sudo nano static-nodes.json ( Save using Ctrl + O , then exit with Ctrl + x )
Create a file called config.toml in node01 folder. Paste contents of config.toml into it:
Config File: https://github.com/CIC blockchain /CIC blockchain -Documentation/blob/main/technology/config.toml
cd node01 sudo nano config.toml
Run screen, to keep node running if you close the terminal:
screen , then hit CIC key.
Run CIC blockchain client from node01 folder:
besu --config-file=config.toml
When the node runs, exit the current screen so it's safe if you close the terminal:
Press Ctrl + A , then press C . Now you can either close the terminal window, or work on other processes.
It should start synchronization in few moments, or minutes. Depending on your machine.
To run more than one node on the same machine, you must set different port numbers in config.toml per each node.
Default ports used:
rpc-http-port=8545 rpc-ws-port=8546 graphql-http-port=8547 metrics-port=9545 p2p-port=30303
To use WEB3 API, make sure WEB3 is enabled. This is the default setting in config.toml
