Description: An external validator is a crucial component in proof-of-stake (PoS) systems, operating outside the main network but playing a fundamental role in the consensus process. These validators are responsible for verifying and validating transactions and blocks proposed by the network nodes, thus ensuring the integrity and security of the system. Unlike internal validators, which are directly integrated into the network, external validators can provide an additional layer of security and decentralization. Their main function is to ensure that the decisions made by the network are fair and transparent, contributing to trust in the system. Additionally, external validators can be incentivized to participate in the consensus process through rewards, encouraging their active participation and the maintenance of the network. This model allows for greater flexibility and scalability, as external validators can be selected based on their reputation and performance, improving the efficiency of the validation process. In summary, external validators are essential for the functioning of proof-of-stake networks, providing a robust mechanism for transaction validation and consensus creation in a decentralized environment.
