What Is Proof-of-Activity as a Hybrid Consensus Model?

Proof-of-Activity (PoA) is a hybrid consensus mechanism combining Proof-of-Work (PoW) and Proof-of-Stake (PoS). PoW miners compete to find a block template with no transactions.

Once found, the block is signed by a randomly selected group of PoS validators based on their stake. This aims to leverage the security of PoW while mitigating the energy consumption and centralization risks.

It provides a more robust security model.
