A » A block in a blockchain is a digital record that contains a list of transactions. Each block is linked to the previous one, forming a chain. It typically includes a cryptographic hash of the previous block, a timestamp, and transaction data. Blocks ensure data integrity and security, as altering one block would require changes to all subsequent blocks, making the blockchain tamper-resistant and trustworthy.
