A Qualified Validator is a participant in a blockchain network who is responsible for confirming and validating transactions. These validators help maintain the integrity and security of the network by ensuring that only legitimate transactions are added to the blockchain.To become a Qualified Validator, one typically needs to meet specific criteria, which may include holding a certain amount of the network’s native cryptocurrency, running specialized software, and maintaining a consistent online presence. This helps ensure that validators are reliable and available to perform their duties.In many proof-of-stake systems, the selection of Validators can also depend on factors like the amount of cryptocurrency staked, experience, or reputation within the community. Qualified Validators earn rewards for their work, which can incentivize them to act honestly and efficiently.By fulfilling these roles, Qualified Validators play a crucial part in achieving consensus on the network and safeguarding it against malicious activities. This process contributes to the overall efficiency and trustworthiness of the blockchain ecosystem.
