POA blockchain, or Proof of Authority blockchain, is a consensus mechanism that relies on a set of pre-verified and trusted nodes, called authority nodes, to validate transactions and generate blocks. It aims to provide a more efficient and secure way of maintaining the blockchain network compared to other consensus algorithms like Proof of Work or Proof of Stake.
