Overview
PoA is a high-performance consensus algorithm used primarily in private or consortium blockchains where the validators are known and trusted entities.
Key Features
- Identity-Based: Validators must undergo a formal identification process.
- Efficiency: Requires very little computational power compared to PoW.
- Predictability: Block generation occurs at regular intervals.
Use Cases
PoA is ideal for enterprise applications, supply chain tracking, and testnets where speed and reliability are prioritized over total decentralization.
