What is Proof of Authority?
Proof of Authority (PoA) is a consensus mechanism used in secure digital ledger networks where transactions and block creation are validated by approved accounts, known as validators. PoA is often employed in permissioned-based DLT networks where the identity of participants is known and trusted. This mechanism is considered more efficient and scalable than proof of work (PoW), as it relies on a limited number of validators rather than extensive computational work.
Proof of Authority is suitable for applications where transactions need to be processed quickly and in a trusted environment, such as in supply chain management, where ensuring the integrity and speed of transactions is critical.
