Blockchain

Definition ∞ A blockchain is a distributed, immutable ledger that records transactions across numerous interconnected computers. Each block of transactions is cryptographically linked to the preceding one, forming a secure and transparent chain of data. This architecture underpins many digital assets and decentralized applications, providing a verifiable and tamper-resistant record of activity.
Context ∞ Discussions surrounding blockchain technology in crypto news frequently focus on its applications beyond cryptocurrencies, such as in supply chain management and digital identity verification. Debates often involve the trade-offs between different consensus mechanisms concerning energy consumption, security, and transaction throughput.
