Validator Selection Bias

Mechanism

This phenomenon arises when the process for choosing network participants to propose or attest to blocks displays non-random patterns that favor specific nodes over others. In the context of derivatives and high-frequency crypto trading, such skewness introduces structural latency and potential information advantages for select market participants. When validators are chosen based on stake concentration or geographic proximity, the resulting distribution of rewards and block space access deviates from idealized decentralization.
