Proof-Of-Authority (Poa)
| Proof-of-Authority (PoA) is a consensus mechanism in which identity is used as a stake. In a PoA system, validators are chosen based on their identity, and they are given the authority to create new blocks and validate transactions. PoA is a popular choice for private blockchains, as it is more efficient and scalable than Proof-of-Work (PoW), and it does not require a lot of computing power. There are a few different ways to implement PoA, but the most common is to have a group of validators that are chosen by the network. These validators are then responsible for validating transactions and creating new blocks. PoA is a great choice for private blockchains because it is more efficient than PoW, and it does not require a lot of computing power. PoA is also more secure than PoW, as it is less susceptible to 51% attacks. |
