Nimiq Proof-of-Stake: Your Ultimate Guide to Getting Started

Feb 13, 2022 | Blockchain

Welcome to the world of Nimiq Proof-of-Stake! As a frictionless payment protocol designed for the web, Nimiq offers an innovative approach to blockchain technology. The current focus is on the Rust implementation of the Nimiq Proof-of-Stake blockchain, which promises high performance without compromising on security. This article will guide you through how to effectively utilize Nimiq’s capabilities, along with troubleshooting tips for a smooth experience.

Background

Nimiq’s Proof-of-Stake is built around the Albatross consensus algorithm, which allows for secure and scalable transactions. If you’re interested in diving deeper, check out the Nimiq Albatross White Paper for technical details.

System Requirements

  • 64-bit computing architecture
  • 2 or more CPU cores
  • 2GB of available RAM memory
  • 5GB of free disk space (SSD highly recommended)
  • File systems with sparse file support
  • Clock synchronization protocol like NTP

Installation

For compiling the source code, you will need the following:

  • Rust stable: Installing Rust
  • clang
  • cmake
  • libssl-dev (Debian/Ubuntu) or openssl-devel (Fedora/RedHat)
  • pkg-config

Once you have these packages, you can compile the project using the following commands:

git clone https://github.com/nimiq/core-rs-albatross
cd core-rs-albatross
cargo build --release

Documentation

Extensive resources are available at the Nimiq Developer Center, where you’ll find everything from protocol details to APIs.

Usage

To run the client once installed, use the following command:

cargo run --release --bin nimiq-client

Configuration

The client looks for a configuration file at $HOME/.nimiq/client.toml automatically. To create one, run:

cargo run --release --bin nimiq-client

This will generate an example configuration file, which you can edit as needed:

cp $HOME/.nimiq/client.example.toml $HOME/.nimiq/client.toml
nano $HOME/.nimiq/client.toml

Testnet

The testnet is available for anyone to explore. Funds can be obtained by using the Testnet Nimiq Wallet or through the Devnet Faucet.

Docker

To pull the latest Docker image, use:

docker pull ghcr.io/nimiq/core-rs-albatross:latest

To run the client, create the appropriate directories and run:

docker run -v $(pwd)/data:/home/nimiq.nimiq -p 8443:8443 -p 8648:8648 -p 9100:9100 --name nimiq-rpc --rm ghcr.io/nimiq/core-rs-albatross:latest

Troubleshooting

If you encounter issues during installation or configuration, ensure all system requirements are met, especially the clock synchronization. Additionally, ensure you have properly installed Rust and all necessary libraries. If things still don’t work, consider reaching out via the issue tracker on GitHub.
