Broadcast refers to the process of sharing information across a network of nodes. In this context, it typically involves transmitting transaction details or block information to all participants in the network.When a user initiates a transaction, their device creates a message containing key details, such as the sender’s and receiver’s addresses and the amount being transferred. This message is then broadcast to the network. Nodes that receive this message validate the transaction by checking various criteria, such as ensuring that the sender has sufficient funds.Once validated, the transaction gets added to a pool of pending transactions. Miners or validators then select transactions from this pool for inclusion in the next block of the blockchain. This broadcasting process ensures that all nodes are updated with the latest information and maintain a synchronized version of the ledger.Overall, broadcasting is crucial for maintaining transparency, security, and consensus within the network, enabling participants to trust that they have the most current data about transactions and the overall state of the blockchain.
