Blockchain is a decentralized technology that enables the secure and transparent transfer and storage of digital assets. It operates as a distributed ledger, recording transactions across multiple computers, called nodes, rather than a central authority. Each transaction is grouped into a block, which is cryptographically linked to the previous block, forming a chain of blocks hence the name "blockchain." Blockchain technology has applications beyond cryptocurrencies. It is being explored in various industries, including supply chain management, healthcare, finance, and more. By eliminating the need for intermediaries and enhancing security and traceability, blockchain has the potential to revolutionize business processes and create new opportunities for innovation.
