What is Zeeka?

In simplest words, Zeeka (ℤ) is a cryptocurrency which aims to provide a light and scalable blockchain by extensively using the help of Zero-Knowledge proof technology.

A Zero-Knowledge protocol is a crytographic method by which someone can prove that they know the answer of a problem without actually revealing it.

ℤ - Bazuka!

Bazuka is a wallet and node software for the Zeeka (ℤ) Protocol. Zeeka is a novel layer-1 cryptocurrency which uses Zero-Knowledge proofs as the backend of its smart-contract (I.e Zero Contracts).

Bazuka ensures the availability of latest contract-states, so that they remain public and everybody is able to update and build on them, making Zeeka a more decentralized protocol compared to similar projects.

At this stage, the minimum server requirements are 1 CPU, 1 GB RAM, 30 GB SSD. You can put it on Hetzner - CPX11 or hook it up to another node on an existing server. Zeeka uses port 8765.

Update system

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install wget jq git libssl-dev cmake -y

Install Rust

sudo apt install curl build-essential gcc make -y

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

source ~/.profile
source ~/.cargo/env

Clone the repository and go to the folder with the node

git clone https://github.com/zeeka-network/bazuka && cd bazuka
git pull origin master

Building binary files

cargo install --path .

Create a new wallet (Keplr for example) and save the mnemonic phrase in a safe place.

Initialize the node, specify the mnemonic phrase of your wallet in the command

bazuka init --seed '<the mnemonic phrase>' --network debug --node 127.0.0.1:8765 

Create a variable with your IP and nickname in discord

ZEEKA_IP=<your IP>
DISCORD_HANDLE=<nickname in discord#numbers>  

Save variables, reload .bash_profile and check variable values

echo "export ZEEKA_IP="${ZEEKA_IP}"" >> $HOME/.bash_profile
echo "export DISCORD_HANDLE="${DISCORD_HANDLE}"" >> $HOME/.bash_profile
source $HOME/.bash_profile
echo -e "\nzeeka_ip > ${ZEEKA_IP}\n"
echo -e "\ndiscord_handle > ${DISCORD_HANDLE}\n"

Create a service file

printf "[Unit]

After=network.target

[Service]

[Install]
WantedBy=multi-user.target" > /etc/systemd/system/zeekad.service

Starting the service

sudo systemctl daemon-reload && sudo systemctl enable zeekad
sudo systemctl restart zeekad

Checking the logs

sudo journalctl -fn 100 -u zeekad

Optional: you can add colors to the log output

sudo apt install ccze

Checking logs in color

sudo journalctl -fn 100 -u zeekad | ccze -A

• In Google Chrome or Brave, download the Keplr extension from the link
• Go to the extension and click "Create new account"
• Enter the account name and password, save the mnemonic phrase in a safe place
• We compose our own mnemonic phrase from the proposed words
• Ready!

To remove a node, run the following commands

systemctl stop zeekad && systemctl disable zeekad
rm -rf $HOME/bazuka /usr/bin/bazuka /etc/systemd/system/zeekad.service
systemctl daemon-reload
