Definition
A block is a basic data unit in a blockchain that groups together a set of verified records, usually called transactions, along with metadata such as a timestamp and references to other blocks. Each block is linked to the previous one, forming a continuous chain of data that is stored and shared across the computers running the blockchain network.
In Simple Terms
A block is like a digital container that holds a bunch of confirmed transactions and some information about when and where they belong in the blockchain. These containers are connected one after another, creating the blockchain that many cryptocurrencies and networks rely on.
Context and Usage
The term block appears in discussions about how blockchain networks organize and store data for cryptocurrencies and other digital assets. It is used when describing how transactions are recorded, how the blockchain grows over time, and how different networks structure their data. Blocks are referenced whenever people talk about the state or history of a blockchain.
