Blockchain is a decentralized digital ledger that securely records transactions across a network of computers. Unlike traditional systems controlled by a central authority, blockchain operates on a peer-to-peer basis, making it transparent, secure, and resistant to tampering.

Each transaction is stored in a “block,” and these blocks are linked together in a chronological “chain.” Once added, data on the blockchain cannot be altered—ensuring trust and accountability without the need for middlemen.

Originally created to support Bitcoin, blockchain technology now powers thousands of cryptocurrencies and is being adopted in industries like finance, supply chain, healthcare, and even sports — from digital fan tokens to NFT collectibles.

Whether you’re a beginner or a crypto enthusiast, understanding blockchain is the first step toward grasping the future of decentralized technology.
