Solana Foundation Validator Discussion - August 28, 2025
Curious about the latest Solana validator discussions? Here’s your summary of the most important takeaways from the community-led call.

Context and Motivation for JIP-25
The meeting opened with a clear explanation of why changes to the Jito stake pool were being proposed under JIP-25. The current system, overly reliant on vote credits, has created an unhealthy arms race that incentivized extreme optimization, sometimes leading to malicious practices like censoring, DDoS attacks, and self-serving MEV behaviors. The goal of the proposal is to reduce these negative externalities and improve the quality and fairness of validator participation.
There was a consensus that while performance matters, vote credits have become too dominant in influencing stake distribution. JIP-25 aims to rebalance those incentives and introduce more transparent, predictable mechanics.
Important Changes in JIP-25
Nick Almond and Brian Smith from the Jito team detailed the proposed structural updates to the validator set:
The stake pool is expanding from 200 to 400 validators, enabling broader participation.
Vote credits will be deprioritized in the ranking system. They now serve only as a tiebreaker after three other primary criteria.
The new ranking hierarchy will be: Standard commission rate (lower is better), MEV commission rate (lower is better), Validator age (older is better, based on continuous history) and Vote credits as a fallback.
These changes are designed to reward long-term operators who maintain reliability and responsible economics. Delegation will shift from a top-down ranked approach to a more even pro-rata allocation across eligible validators.
Validator age will be measured using historical data tracked by the StakeNet system, which has been collecting validator metadata, including activity and performance, for over two years. There was debate over whether to backfill older data, with concerns raised about both technical limitations and the diminishing significance of age beyond two years.
Feedback on Fairness, Gaming, and MEV Metrics
Community members raised important questions about whether validators might game MEV commission metrics by advertising 0% while avoiding bundles or injecting their own. Concerns were voiced about misleading validator behavior, especially in cases where real earned MEV does not match the advertised rate.
The team acknowledged this and said StakeNet already tracks actual MEV earned, which could be used in future scoring refinements. While JIP-25 relies on stated commission rates for now, there is openness to adjusting the model to account for actual performance and preventing manipulative behavior.
Governance and Timeline
The proposal is currently in a two-week community review phase. One week remains before the vote. If passed, implementation would begin immediately afterward, with initial effects visible within 20 days. Some parts, especially those involving engineering, may take longer to complete.
Attendees were encouraged to submit feedback or propose alternatives on the Jito governance forum. The team emphasized this is phase one of a broader evolution, not the final version.
Future: Directed Staking and Phase Two
JIP-25 also lays groundwork for phase two, which introduces a directed staking feature. This would allow:
Large JitoSOL holders to direct a portion of their delegated stake to specific validators
DeFi protocols running validators to benefit from increased stake
Up to 30% of the pool to be manually allocated, with the majority still controlled algorithmically
This mechanism would rely on an on-chain ticketing system to enable users to make cryptographic staking decisions. It is designed to better align incentives between validators and stakeholders who are actively contributing to the Solana ecosystem.
Discussion acknowledged the tension between making delegation more flexible and avoiding excessive complexity or favoritism. Directed staking remains in draft form and is open to feedback.
Community Discussion and Concerns
The open Q&A raised several points of interest:
Churn from rebalancing is costly, so validator sets cannot be adjusted too frequently without harming returns.
Some suggested increasing the validator cap further, to 500 or beyond, while others warned against doing too much too soon.
Stake pool mechanics were debated, with strong opinions against monetizing governance votes and enabling mechanisms like tokenized vote markets.
Several dashboards were shared for tracking predicted JIP-25 rankings and eligibility, including from Trillium, CryptoVik, and PineStake.
There was also discussion about ensuring validators don't mislead stakers with strategic MEV configurations, and a recommendation to more closely monitor actual income versus advertised commission.
Closing and Additional Topics
The meeting concluded with a brief showcase of VoteX, a platform for buying and selling governance votes in stake pools. This sparked strong reactions, with some viewing it as a governance innovation and others criticizing it as compromising validator quality. The concept of markets for vote tokens was debated with concerns about the integrity of governance and decentralization.
Final announcements covered the upcoming Block Zero meetup, with reminders for validators to register using their validator identities and submit session topics or speaker proposals.
