Blockchain technology is the backbone of cryptocurrencies. It is a distributed ledger that records all transactions across a network of computers. This ensures transparency, security, and immutability, making it difficult for any single entity to manipulate the system. Each block contains a list of transactions and is linked to the previous one, forming a chain. This technology isn't just limited to cryptocurrencies; it has potential applications in various industries, including supply chain management, healthcare, and voting systems, offering a secure and transparent method of data management. 🔗🔒🩺
