Blockchain Technology

Blockchain is a distributed ledger technology where records are stored across many computers in linked 'blocks.' Each block contains transactions and a cryptographic hash of the previous block, making the chain tamper-evident. Beyond cryptocurrency, blockchain enables smart contracts, supply chain tracking, and decentralized systems. The technology trades efficiency for security and decentralization, sparking debate about its appropriate applications.
