What is blockchain?

Blockchain is a decentralized digital ledger that records transactions and data points in a secure and immutable manner. Unlike traditional centralized systems, blockchain technology distributes data across a global network of nodes. Each transaction is verified through consensus mechanisms, ensuring accuracy and security without the need for intermediaries. This innovation underpins cryptocurrencies, decentralized finance (DeFi), and smart contract platforms, enabling a transparent and tamper-proof digital ecosystem.
