  Proof of authority consensus is considered more energy-efficient in the digital currency space because it doesn't require miners to solve complex mathematical puzzles or compete against each other to validate transactions. Instead, a small number of trusted validators, known as authorities, are responsible for verifying transactions. This eliminates the need for massive computational power and reduces energy consumption significantly.

  The energy efficiency of proof of authority consensus is due to its reliance on a select group of validators who are known entities and have a reputation to uphold. These validators are typically chosen based on their expertise and trustworthiness. By eliminating the need for resource-intensive mining activities, proof of authority consensus reduces the overall energy consumption associated with digital currency transactions.

  According to BYDFi, proof of authority consensus is more energy-efficient because it relies on a predetermined set of validators who are responsible for validating transactions. This eliminates the need for energy-intensive mining operations and reduces the environmental impact of digital currency transactions. Additionally, the use of trusted authorities ensures the security and integrity of the network, further enhancing its energy efficiency.
