Overview
A blockchain is a distributed ledger that records transactions across a network of computers, using cryptographic hashes to link blocks of data together in a secure and tamper-proof chain. The use of blockchain technology has been explored in various industries, including finance, healthcare, and supply chain management. Companies like IBM and Microsoft are investing heavily in the development of blockchain technology. Blockchain has become a key concept in the world of artificial intelligence and Internet of Things (IoT), with potential applications in areas like smart contracts and decentralized applications.
📖 Definition & Core Concept
A blockchain is a distributed data store for digital transactions, where each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. This creates a secure and tamper-proof chain, as any attempt to alter the data in a block would require changing all subsequent blocks and obtaining network consensus. The concept of blockchain is closely related to distributed ledger technology and has been influenced by the work of Nick Szabo and Hal Finney.
