Blockchain is a distributed ledger technology that enables data and value to be recorded, verified, and shared across a network of computers. It reduces reliance on a single intermediary by using cryptographic linking, distributed nodes, and consensus rules.
This module explains the subject in clear academic language while remaining accessible to business and public audiences.
Distributed ledgers maintain synchronized records across participants.
Learn More →Blocks contain transactions and reference previous blocks using cryptographic hashes.
Learn More →Nodes validate, store, and relay data across the network.
Learn More →Immutability means records become tamper-evident after confirmation.
