Validator Fairness
Validator fairness is the principle that all participants in a consensus mechanism should have an equal opportunity to propose blocks and earn rewards. If a protocol favors certain validators over others, it risks centralization and censorship.
Mechanisms such as randomized proposer selection are used to distribute this power evenly across the network. Fairness also extends to the handling of transaction fees and the prioritization of user requests.
Ensuring a level playing field is essential for maintaining the security and decentralization of the entire network.
