It maintains the security and stability of the network through a set of authoritative nodes, which are usually verified and trusted third-party institutions. In this consensus algorithm, authoritative nodes are responsible for validating transactions and generating new blocks to be added to the blockchain. Compared to other consensus algorithms such  as Proof of Work (PoW) and Proof of Stake (PoS), Proof of Authority offers faster confirmation speeds, lower energy consumption, and higher security. Additionally, PoA has a stronger centralized feature, making it suitable for scenarios with higher regulatory and compliance requirements."}]}],"pr":"62b7be7263cee70ac33703228974b3aad79079c0f3bcf4380a67c69c9b30e0eb"}
