Stake Weight

Stake weight refers to the proportional influence a participant holds within a proof of stake consensus mechanism, determined by the amount of cryptocurrency they have locked or staked. In this system, the probability of being selected to validate transactions and earn rewards is typically correlated with the size of the stake relative to the total staked supply.

It functions as a mechanism for aligning economic incentives, ensuring that those with the most capital at risk are motivated to maintain network integrity. High stake weight grants greater authority in governance votes and block production, essentially serving as a proxy for trust in decentralized systems.

However, this can lead to wealth concentration, where larger holders exert disproportionate control over protocol parameters. The concept is central to protocol physics, as it defines the security budget and the cost of potential adversarial attacks like grinding or long-range attacks.

Understanding stake weight is essential for evaluating the decentralization profile and economic security of any proof of stake network.
