Blockchain is a decentralized, tamper-proof system for recording transactions and tracking assets. Unlike traditional databases, it doesn’t rely on a central authority. Instead, data is stored in blocks that are linked together and shared across a network of computers (nodes). This makes the system transparent, secure, and nearly impossible to alter.
Blockchain powers cryptocurrencies like Bitcoin but has many other uses. It’s used in finance, supply chains, digital art (NFTs), and even voting systems — anywhere trust, security, and transparency are needed. Whether you’re transferring value or verifying ownership, blockchain helps cut out the middleman and builds trust through code.
