In this episode, we cover Directed Acyclic Graph or DAG.

In blockchain, we have blocks as collection of transactions and the current block references the previous one, and a chain is formed.

In DAG, we don’t have any blocks. Transactions directly reference previous transactions. The nodes verify the previous transactions by referencing them in new transactions.

When a new transaction is submitted to a DAG, some previous transactions are referenced in it.
