# Proof of Authority (PoA) Consensus Mechanism

The CAGA network employs a Proof of Authority (PoA) consensus mechanism, which prioritizes speed and energy efficiency. Unlike Proof of Work (PoW) systems that require extensive computational resources, PoA relies on the reputation and authority of its validators to maintain network integrity. This system facilitates faster transactions and significantly reduces the network's energy consumption, aligning with CAGA's commitment to sustainability.
