  Proof of authority (PoA) offers several benefits in the realm of digital currencies. Firstly, it provides a high level of security and eliminates the need for resource-intensive mining. With PoA, transactions are validated by trusted authorities, reducing the risk of fraudulent activities. Additionally, PoA enables faster transaction confirmations, as there is no need to wait for multiple nodes to reach consensus. This makes it ideal for applications that require quick and efficient transactions, such as online payments or micropayments.

  Using proof of authority in digital currencies has its perks. Unlike proof of work (PoW) or proof of stake (PoS), PoA doesn't require extensive computational power or large amounts of tokens to participate in the consensus process. Instead, it relies on trusted authorities who are responsible for validating transactions. This results in a more energy-efficient and cost-effective system. Moreover, PoA reduces the risk of 51% attacks, as the trusted authorities are unlikely to collude and compromise the network.
