Build a cryptocurrency with Node.js

Blockchain technology serves as a digital ledger shared among computer nodes, facilitating the operation of cryptocurrencies and decentralized applications by recording transactions in encrypted blocks. Despite being in its early stages, blockchain has applications across various sectors, including finance, government, and the arts, creating numerous job opportunities. Cryptocurrencies, secured through cryptographic methods, rely on blockchain for ensuring security and data integrity. The tutorial guides Node.js developers in creating a basic cryptocurrency by first explaining the properties of a blockchain, such as proof of work, block hash, and timestamps, before demonstrating the setup process using Node.js and the crypto-js package. It involves creating a genesis block and subsequent blocks, validating the chain’s integrity, and ultimately building a simple cryptocurrency called logCoin. While the tutorial's outcome doesn’t align with market standards, it provides foundational knowledge for aspiring blockchain developers.
