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.

How to run a Bazuka node?

NOTE: Bazuka! is a very early-stage implementation of the Zeeka Protocol, highly unstable and not yet complete!

If you only want to run a Zeeka node and do not want to execute Zero Contract or mine Zeeka, you will only need to install bazuka (This repo). In case you also want to mine Zeeka, you will need to install (The Main Payment Network executor) and also the (A RandomX CPU miner).

How to install bazuka?

• Prepare a Linux machine.
• Make sure you have installed libssl-dev and cmake packages.
• Install the Rust toolchain (https://rustup.rs/)
• Clone the bazuka repo: git clone https://github.com/zeeka-network/bazuka.
• Compile and install: cd bazuka && cargo install .

Now if you want to join the debug testnet, you first have to initialize your node by running:

bazuka init --seed [your seed phrase] --network debug --node 127.0.0.1:8765

Your regular and zero-knowledge private-keys are derived from the --seed value, so don't forget to keep them somewhere safe! You can choose your target network (E.g mainnet, chaos, debug or etc.) through the --network option. You should also choose the node which you want to send your transactions to, through the --node option. (Here we choose our local node which we will run later)

Run your node:

bazuka node --listen 0.0.0.0:8765 --external [your external ip]:8765 \
  --network debug --db ~/.bazuka-debug --bootstrap [comma separated list of bootstrap nodes]

You can use the nodes introduced by the community as your --bootstrap nodes. You either have to run your node on a machine with a static IP, or configure a NAT Virtual Server in order to expose your node on a public IP. Specify your public IP through the --external option.

What is the Main Payment Network?

The Main Payment Network (MPN) is a special, builtin smart-contract that is created in the genesis-block of the Zeeka Protocol. It manages a merkle-tree of millions of accounts that can transfer ℤ with each other with nearly zero-cost transactions. It uses the Groth16 proving system and has a fixed number of transaction slots per update.

People who want to transfer their Zeeka tokens cheaply, would need to deposit their funds to MPN through the deposit command.
