  A Directed Acyclic Graph (DAG) is a data structure that is used in some cryptocurrencies as an alternative to traditional blockchain technology. Unlike a blockchain, which consists of blocks linked together in a linear chain, a DAG is a more complex structure where transactions are represented as vertices and are connected to each other in a directed manner. This allows for a more scalable and efficient system, as transactions can be processed in parallel rather than sequentially. DAG-based cryptocurrencies, such as IOTA and Nano, claim to have higher transaction throughput and lower fees compared to traditional blockchain-based cryptocurrencies.

  In a DAG-based cryptocurrency, each transaction needs to validate two previous transactions before it can be confirmed. This is achieved through a process called the 'tangle', where transactions are validated by referencing previous transactions. The tangle ensures that each transaction is indirectly confirmed by multiple other transactions, creating a web-like structure. This consensus mechanism eliminates the need for miners and allows for a more decentralized and lightweight network. However, it also introduces some challenges, such as the possibility of double-spending attacks.
