Overview
Blockchain is a distributed ledger technology that stores data in a sequence of blocks, each containing a cryptographic hash of the previous block, a timestamp, and transaction data, making it resistant to alteration and ensuring the integrity of the data. Blockchain has applications beyond digital currency, including supply chain management, voting systems, and more. The decentralized nature of blockchain allows for peer-to-peer transactions without the need for intermediaries. Blockchain is being explored for its potential in healthcare, education, and energy management, with companies like IBM and Microsoft investing heavily in blockchain research and development.
📖 Definition & Core Concept
Blockchain technology is built on the concept of a distributed ledger, where data is stored in a sequence of blocks, each linked to the previous one through cryptographic hashes. This creates a chain of blocks, hence the name blockchain.
