Blockchain technology is a system used to record information in a safe and clear way. It works like a digital ledger where data is stored in blocks, and each block is connected to the one before it, forming a chain. Once data is added, it cannot be changed easily, making blockchain very secure. It is used in cryptocurrencies like Bitcoin but also in other areas like banking, healthcare, and supply chains. Because it does not need a central control, it helps build trust between users. Many people see blockchain as a powerful tool for the future of digital systems and records.
