POA
**POA**
What is POA?
Proof of Authority (PoA) is a consensus mechanism used in blockchains where transactions are validated by approved participants, known as authorities or validators. These validators are typically pre-selected and have a reputation at stake, encouraging them to act honestly. PoA blockchains are generally faster and more efficient than Proof-of-Work (PoW) or Proof-of-Stake (PoS) blockchains but are also more centralized. It is commonly used in private or permissioned blockchains where trust and identity are important.
