Block

In the context of cryptocurrencies and blockchain technology, a block is a fundamental component of the blockchain. It is a digital record or container that stores a collection of transactional data, typically including details such as sender and receiver addresses, transaction amounts, timestamps, and other relevant information. Each block is cryptographically linked to the previous block through a unique hash, forming a continuous and immutable chain—hence the term blockchain.

Blocks are created through a process called mining (in proof-of-work systems) or forging (in proof-of-stake systems), depending on the consensus mechanism used by the blockchain network. Once validated and added to the blockchain, blocks become part of a decentralized and transparent ledger that records all transactions ever made within the network. This structure ensures the integrity, security, and decentralization of the cryptocurrency system.
