Blockchain has a wide range of real-world applications. It can be used in supply chain tracking, healthcare for managing patient records, digital identity systems, decentralized finance (DeFi), gaming, and intellectual property protection. The technology ensures transparency, reduces fraud, and builds trust by making all interactions verifiable and tamper-proof.
