When working with blockchain block, a unit of data that records a batch of transactions and references the previous block via a cryptographic hash. Also known as block, it forms the immutable chain that powers every cryptocurrency. Blockchain block encompasses transaction data, timestamp, and a hash that secures the ledger. It requires a consensus algorithm to validate each entry, linking the new block to the prior one and creating a chronological record that cannot be altered. This simple structure enables complex systems like smart contract, self‑executing code that runs when predefined conditions are met on the blockchain to trigger automatically, because contracts read the block data to confirm events. Understanding blocks is the first step to grasping why decentralized finance, financial services built on blockchain that operate without traditional intermediaries can run 24/7, settle instantly, and remain transparent.
Every block not only stores transactions but also provides the context that oracles need to feed external data into the chain. An oracle, a service that supplies real‑world information to smart contracts reads block headers to verify the timing and authenticity of data before it reaches a contract, reducing the oracle problem where inaccurate feeds could corrupt outcomes. This connection means that reliable blocks support trustworthy DeFi pricing, loan calculations, and even the distribution of crypto airdrops. When an airdrop program checks a block for user eligibility—say, holding a token at a certain block height—it relies on the block’s immutable record to prevent fraud. So, blocks are the backbone that lets developers design secure token giveaways, ensure fair staking rewards, and protect users from phishing attacks that try to spoof transaction histories.
