What Is Blockchain

A blockchain is a distributed ledger with growing lists of records, called blocks, that are securely linked together via cryptographic hashes, making it resistant to alteration and allowing for secure, transparent, and tamper-proof transactions. Blockchain has been widely adopted in various industries, including finance, healthcare, and supply chain management. Companies like IBM and Microsoft are investing heavily in blockchain research and development. The use of blockchain has been explored in artificial intelligence and Internet of Things applications, further expanding its potential.
