Solana's implementation of binding on-chain governance through SGP gives stakers meaningful power to override validators, marking a genuine decentralization milestone that reduces capture risk.

"The Solana Foundation launched a fully on-chain governance system called Solana Governance Proposals, giving validators and everyday stakers a formal, binding vote on the network's direction for the first time. By default a validator votes with all the SOL delegated to it. But under the new system, any delegator who disagrees can cast their own ballot and yank their stake weight out of the validator's total."
