Episode details

In general, consensus means agreement. In the context of blockchain, consensus is the agreement on the state of the blockchain among all the nodes in a network.

The main area where consensus is needed is the order of transactions, within a block. If all nodes could agree on the order in which the transactions happened, then they would individually arrive at the same state after processing the respective blocks.
