Block

A block on the blockchain is a digital record containing a batch of verified transactions and data. Each block includes a unique identifier, a timestamp, and a cryptographic hash linking it to the preceding block, forming an immutable chain.

The block contains transaction data, such as sender and recipient details, amounts, and other relevant information. It also houses a header, which includes metadata and the hash of the previous block, ensuring continuity and security.

This structure guarantees that data within each block remains secure, tamper-resistant, and transparent. New blocks are added through consensus mechanisms like Proof-of-Work or Proof-of-Stake, ensuring network agreement and forming a continuously updated, decentralized ledger that underpins the trustworthiness of the blockchain system.
