Definition ∞ Stake-ranked tiers are a system within proof-of-stake networks where validators or participants are categorized into different levels based on the amount of cryptocurrency they have staked. Higher tiers typically correspond to greater responsibilities, increased chances of being selected to validate blocks, and potentially larger rewards. This structure can influence network security and decentralization dynamics. It provides a stratified incentive model.
Context ∞ The implementation of stake-ranked tiers often generates debate regarding its impact on network decentralization, as it can potentially concentrate power among large stakers. Protocol designers constantly evaluate these tiering systems to ensure they promote fair participation and prevent undue influence by a few entities. Future research aims to refine these models to optimize for both security and equitable distribution of validation opportunities.
