Blockchain is a distributed ledger technology that records transactions across multiple computers securely. Each block contains data, a timestamp, and a link to the previous block, forming a chain. This design makes tampering nearly impossible. Blockchain is the backbone of cryptocurrencies like Bitcoin and Ethereum but has broader applications, including supply chain tracking, voting systems, and smart contracts. Its decentralized nature eliminates intermediaries, reducing costs and increasing efficiency. Transparency and immutability are key features, making blockchain revolutionary for many industries.
