Power Imbalances in Proof-of-Stake Governance Analyzed
A new study on arXiv (2605.19264) examines power distortions in stake-weighted voting, the core governance mechanism of Proof-of-Stake blockchains. Using the Penrose-Banzhaf power index, researchers demonstrate analytically that perfect alignment between voting power and stake ownership is generally impossible, though approximation is possible under specific conditions. Empirically, data from Project Catalyst, a real-world on-chain governance system, reveals significant power imbalances where a few large stakeholders can dominate decision-making without majority ownership. The work contributes to computational social choice theory and highlights systemic risks in current PoS governance.
