How Does Proof-of-Activity Address the Energy Consumption Issue of Pure Proof-of-Work?

Proof-of-Activity (PoA) reduces energy consumption compared to pure PoW because the PoW part is only used to create a block template. Full block mining competition is avoided.

After the template is created, the block is finalized by Proof-of-Stake (PoS) validators, which is an energy-efficient process. This design shifts the bulk of the consensus work away from continuous, energy-intensive hashing.
