Open-source altcoins are cryptocurrency projects

Open-source altcoins are cryptocurrency projects other than Bitcoin, with their source code publicly available, allowing developers to contribute. Popular examples include Litecoin (LTC), Nano (XNO), Ravencoin (RVN), Peercoin (PPC), and Dogecoin (DOGE); most are supported by active GitHub repositories.

Featured Open-Source Altcoins

  • Litecoin (LTC): A Bitcoin fork offering faster transaction confirmations, licensed under MIT.
  • Nano (XNO): Uses a block-lattice structure for free, instant transfers; nano-node repo is BSD-3 licensed.
  • Ravencoin (RVN): Asset transfer-focused blockchain, Ravencoin Core is open under MIT license.
  • Dogecoin (DOGE): Popular meme-based coin, dogecoin repo is MIT licensed.
  • Peercoin (PPC): One of the first with PoW/PoS hybrid model, peercoin repo is MIT licensed.

Other Examples

Projects like Stellar (XLM), Algorand (ALGO), and Ravencoin are also open-source and accessible via GitHub; some use PoW or PoS consensus mechanisms. These lists are compiled from weekly updated sources like “best-of-crypto,” ranked by development activity. Check GitHub repos for full lists.

Open-Source Altcoin Development Starter Resources

Open-source altcoin development starter resources include existing blockchain forks, starter kits, and tutorials; start with Linux environments (Ubuntu recommended) and tools like Git, GCC, Hardhat.

Required Tools and Setup

  • Operating System: Install a Linux distro like Ubuntu, plus C++ compiler (GCC), Git, CMake, and Boost libraries.
  • Development Environment: Use Visual Studio Code or CLion IDEs; download full node software to run nodes.
  • Blockchain Starter Kit: Clone GitHub’s shivam6862/blockchain-starter-kit (git clone https://github.com/shivam6862/blockchain-starter-kit), then run npm install in contract, frontend, and backend directories.

Step-by-Step Starter Guide

  1. Define Purpose: Specify the altcoin’s use case (fast transactions, PoS/PoW) and tokenomics (supply, distribution).
  2. Fork or New Blockchain: Fork existing code like Litecoin or create ERC-20 token on Ethereum/Binance Smart Chain; compile smart contracts with Hardhat (npx hardhat compile).
  3. Test: Deploy on testnet (npx hardhat run scripts/deploy.js --network localhost), run unit/integration tests, and apply security audits. GitHub repos (e.g., best-of-crypto) and guides like Rapid Innovation’s ultimate guide provide detailed steps.

Are There Any Made with Golang?

Yes, there are many popular and robust open-source cryptocurrency projects developed with Go (Golang). Go’s performance, concurrency capabilities, and networking strengths make it highly popular among blockchain developers.

Below are standout projects developed with Go and resources to explore for starters:

Major Projects Developed with Go (Golang)

These projects’ source code is fully open-source and demonstrate Go’s proficiency in blockchain:

  • Ethereum (Geth): Ethereum network’s most popular client, “Go Ethereum” (Geth), is entirely written in Go. It forms Ethereum’s backbone.
  • Avalanche (Go-Avalanche): Avalanche platform’s main app is written in Go (by Ava Labs), offering high transaction speeds.
  • Cosmos (Cosmos SDK): Popular infrastructure for building your own blockchain, fully developed in Go (e.g., Binance Chain uses it).
  • Decred (Dcr): This altcoin with hybrid PoW/PoS consensus has a clean, modular Go codebase (btcsuite-based).
  • Lightning Network (LND): Bitcoin’s Layer-2 payment protocol main app is developed in Go.
  • Algorand & Fantom: Core protocols of these high-performance blockchains are also written in Go.

Resources for Developing Your Own Altcoin with Go

If you want to build from scratch or learn with Go, these resources will guide you:

  1. Gocoin: Full Go implementation of Bitcoin protocol. Great for learning how Bitcoin works via Go code.
  2. The Crypto Project: Decentralized blockchain mimicking Bitcoin/Ethereum features for learning. Shows P2P networking in Go (using libp2p).
  3. Simple Blockchain Example: Very basic Go projects showing core block structure and chain logic for beginners.
  4. Tutorial Videos: YouTube series like “Build a Cryptocurrency Exchange in Go” cover practical topics like API usage and matching engines.

In summary, Go is a “first-class citizen” in the blockchain ecosystem. Especially examining Cosmos SDK or Geth codebases is the best starting point for professional-level development.
