Solana has officially approved a major shift in its fee distribution model, with validators now set to receive 100% of priority fees. The governance proposal passed with 77% support on Monday night, marking a pivotal moment for the blockchain’s economic structure and network efficiency.
This change, documented under Solana Improvement Document 0096 (SIMD-0096) and implemented via the feature “Reward Full Priority Fee to Validator #34731,” aims to enhance transparency, discourage off-chain arrangements, and strengthen validator incentives. By reallocating all priority fees directly to validators, Solana is reinforcing the role of these critical network participants in maintaining security and performance.
The Role of Validators in the Solana Network
Validators are the backbone of any proof-of-stake blockchain, and Solana is no exception. These nodes are responsible for processing transactions, producing blocks, and ensuring consensus across the network. To run a validator, participants must stake SOL tokens as collateral, aligning their interests with the health and integrity of the ecosystem.
On Solana, users can choose to pay an additional priority fee to expedite transaction processing—especially useful during periods of high network congestion. These fees act as a market-driven mechanism to prioritize transaction inclusion. With the new model, 100% of these fees will go directly to validators, replacing the previous split system.

Why the Change Was Necessary
Previously, Solana operated under a 50/50 fee split: half of all priority fees were burned (removed from circulation), while the other half went to validators. While this model aimed to introduce deflationary pressure, it had unintended consequences.
As highlighted by tao-stones, the creator of the proposal on the Solana Forum, this structure created misaligned incentives. Some validators began engaging in private arrangements with traders or bots—offering preferential transaction ordering (commonly known as MEV, or Maximal Extractable Value) in exchange for extra payments outside the official fee system.
These opaque deals undermined fairness and transparency, potentially disadvantaging retail users and smaller participants. By redirecting all priority fees to validators, Solana aims to internalize these economic benefits within the protocol itself, reducing the need for side agreements.
How Full Priority Fee Distribution Improves Network Integrity
The shift to full validator rewards isn’t just about economics—it’s a strategic move to improve overall network behavior.
Incentivizing Honest Participation
When validators capture 100% of priority fees, they have a stronger financial incentive to maintain high uptime, process transactions efficiently, and avoid malicious activity. This alignment ensures that those securing the network are directly rewarded for their contributions, fostering long-term sustainability.
Moreover, eliminating the burn component simplifies the fee structure. Users now know that their priority payments are going entirely to the validators who validate their transactions—increasing transparency and trust.
Reducing Off-Chain Coordination
Private transaction routing and payment deals often occur in environments where on-chain rewards are insufficient. By making on-chain earnings more lucrative, Solana reduces the appeal of such arrangements. This promotes a more open and equitable transaction environment, where access isn’t determined by backroom deals but by market-based bidding.
This reform also supports future upgrades related to MEV mitigation and fair transaction ordering, laying groundwork for protocols like MEV-share or sealed-bid auctions, which could further democratize access.
Technical Implementation and Timeline
The change was enacted through SIMD-0096, a formal governance proposal outlining the technical and economic rationale behind full fee redistribution. It leverages existing Solana runtime capabilities, meaning no hard fork was required—only a coordinated network upgrade.
Key implementation details include:
- All priority fees collected from transactions are now directed to the validator that includes the transaction in a block.
- The burn mechanism for priority fees has been disabled.
- Fee calculation remains dynamic, based on supply and demand for blockspace.
- No changes were made to base transaction fees or staking rewards.
This update rolled out seamlessly across mainnet-beta, with monitoring tools showing stable performance post-deployment. Developer tooling and wallets have also been updated to reflect the new fee dynamics.
Frequently Asked Questions (FAQ)
Q: What are priority fees on Solana?
A: Priority fees are optional payments users add to their transactions to increase processing speed during times of congestion. They allow users to bid for faster inclusion in blocks.
Q: Why did Solana change its fee model?
A: The old 50/50 split encouraged off-chain deals between validators and traders. By giving 100% of fees to validators, Solana aligns incentives, improves transparency, and reduces unfair advantages.
Q: Does this make transactions more expensive?
A: Not necessarily. The fee amount is still determined by market demand. However, users benefit from a more predictable and transparent system where payments directly influence service quality.
Q: How does this affect SOL tokenomics?
A: Removing the burn component reduces deflationary pressure slightly. However, increased validator revenue may lead to lower selling pressure, as validators earn more from operations rather than liquidating staked tokens.
Q: Will this centralize power among large validators?
A: While larger validators may earn more in absolute terms, the change applies uniformly across all nodes. Ongoing efforts in MEV distribution and decentralization remain key focus areas for the Solana Foundation.
Q: Can users still get fair access to blockspace?
A: Yes. The auction-like priority fee system remains open to all. Future upgrades may introduce mechanisms like MEV-sharing or first-price auctions to ensure fairness.
Looking Ahead: A More Sustainable and Transparent Ecosystem
This governance decision reflects Solana’s commitment to evolving its economic model based on real-world usage patterns and community feedback. By empowering validators with full fee capture, the network takes a significant step toward greater efficiency, security, and decentralization.
As blockchain ecosystems mature, aligning incentives becomes increasingly crucial. Solana’s move sets a precedent for how high-throughput networks can manage congestion pricing while minimizing corruption risks and promoting open participation.
With clearer rewards and reduced reliance on opaque deals, both validators and users stand to benefit from a healthier, more transparent economy.
