Block

In the context of a blockchain, a block represents a data record containing information about all the transactions that occur within a specific time frame on the blockchain network. Blocks are added sequentially to the chain of data, forming the public ledger known as the blockchain. For example, a Bitcoin block includes details such as the date, time, and number of transactions, as well as signature information indicating the origin and destination of the transfers. Before a chain can continue transacting and creating new blocks, the network must confirm the validity of each block through a process of consensus.
