Blockchain technology is revolutionizing multiple industries beyond cryptocurrency, including finance, supply chain, healthcare, and digital identity management. Its decentralized nature reduces the risk of fraud, enhances security, and provides immutable record-keeping. By eliminating intermediaries, blockchain improves efficiency and reduces transaction costs. Smart contracts, self-executing agreements on the blockchain, enable automation of complex transactions. Additionally, blockchain enhances transparency by allowing all participants to verify and audit transactions in real time.
