What Is Proof-of-Activity as a Hybrid Consensus Model?
Proof-of-Activity (PoA) is a hybrid blockchain consensus mechanism that combines Proof-of-Work (PoW) and Proof-of-Stake (PoS). It aims to leverage the security of PoW while being more energy-efficient like PoS.
The process begins with miners solving a cryptographic puzzle to create a new block (PoW). Then, a group of validators is randomly selected to sign and approve the new block (PoS).
This dual approach is designed to make the network more resistant to attacks.
