Blockchain technology is a system that securely records information across many computers in a way that prevents changes or hacking. It works as a digital ledger, where transactions or data are stored in “blocks” that are linked together, forming a chain. This structure ensures transparency, security, and trust without needing a central authority.

Originally created to support cryptocurrencies like Bitcoin, blockchain is now used in various fields, including supply chain management, healthcare, and voting systems. By providing a reliable and decentralized way to verify information, blockchain has the potential to revolutionize many industries. Shutdown123
