Proof of Activity (PoA) is a hybrid consensus mechanism combining Proof of Work and Proof of Stake for blockchain security.

Proof of Activity (PoA) is a hybrid consensus algorithm used in blockchain networks. It combines elements of both Proof of Work (PoW) and Proof of Stake (PoS). Initially, miners perform PoW to create empty blocks. These blocks are then filled with transactions and validated by randomly chosen stakeholders. PoA enhances security by leveraging the energy-intensive PoW process and the economic stake in PoS. This dual-layer approach aims to improve network efficiency and security. It also reduces the energy consumption associated with traditional PoW while maintaining decentralization.
