The Solana Foundation launched a fully onchain governance system on July 1, 2026, giving validators and SOL stakers a formal, binding mechanism to vote on protocol-level decisions for the first time in the network’s history.
The system, called Solana Governance Proposals, or SGPs, is stake-weighted, Merkle-verified, and live at governance.solana.com, according to the Foundation’s announcement.
The central design question SGPs answer is not technical implementation but intent: OCC Research describes the model as a “representative democracy with voter override,” where validators cast votes by default but any individual staker can directly override that vote with their own stake weight deducted from the validator’s total.

How the Solana SGP System Actually Works
Any validator with at least 100,000 SOL delegated, roughly $7.7 million at launch prices, can submit a proposal. That threshold filters out spam while keeping the system permissionless for sufficiently large operators.
Before a formal vote opens, the proposal must first collect endorsements representing at least 15% of cluster stake; proposals that fall short simply expire.
Once that support threshold clears, the proposal runs an approximately 11-epoch lifecycle: seven epochs for community discussion, one epoch for a Node Consensus Network (NCN) snapshot that locks in voting weights, and three epochs for the formal vote.

Each epoch on Solana lasts roughly two days, making the full process around 22 days end-to-end. To pass, an SGP needs at least 66.67% of For-plus-Against votes to vote in favor; abstentions are excluded from the denominator entirely.
The cryptographic backbone runs on two onchain programs: ncn-snapshot, which builds a canonical Merkle tree of validator stake from the Solana ledger, and svmgov, the voting program that checks every ballot cast against that tree.
A small committee of roughly seven to ten independent operators independently builds those Merkle trees and votes on a canonical snapshot before results are published on-chain, according to OCC Research’s governance analysis.

The Staker Override: Why It Matters
The staker override is the feature that most directly affects retail SOL holders. By default, a validator votes with the full stake delegated to it, a representative model that mirrors how most proof-of-stake networks handle governance.
The difference here is that delegators who disagree with their validator’s vote, or whose validator did not vote, can cast their own ballot directly through the governance dashboard.
When a staker votes independently, their stake weight is subtracted from the validator’s total and counted under the staker’s own choice. OCC Research frames this as resolving the classic principal-agent problem in crypto governance by granting “ultimate sovereignty to stakers” without requiring them to run their own node or move delegations. For a network with more than 1.2 million stakers, that is a meaningful expansion of who can participate in protocol decisions.
Solana’s nine consecutive quarters of dApp revenue growth underscore why governance over this network carries real economic stakes; the decisions SGPs will ratify affect fee structures, inflation schedules, and protocol economics that flow through a high-activity ecosystem.

SGPs vs. SIMDs, Two Separate Tracks
SGPs and Solana Improvement Documents (SIMDs) are deliberately distinct. Per the solana-governance-proposals repository, a SIMD answers “how exactly do we do this”, decided by technical review from core developers. An SGP answers “should we do this”, decided by a stake-weighted onchain vote from validators and stakers.
By default, decision-making stays with developers through the SIMD process. An SGP interrupts that path only when the 15% stake-support threshold is met, functioning as both a governance tool and a circuit breaker on developer-led changes that attract significant stakeholder disagreement.
This separation is what governance researchers at OCC called “arguably the most sophisticated governance system in any major L1,” pointing specifically to the stakeholder override and the NCN architecture as the key innovations.
3/ How are SGPs different from SIMDs?
All governance proposals need to be SGPs. SIMDs are technical in nature and small in scope.
SIMDs should focus on protocol changes, SGPs should be signals from the ecosystem.

The 100,000 SOL proposal bar has drawn some criticism; smaller validators and grassroots groups may need to form coalitions to reach the threshold, keeping agenda-setting power concentrated among the largest operators.
Real-world participation rates and the usability of the override interface will determine how much of the system’s theoretical decentralization translates into practice. The first major economic or fee-model SGP to run the full process will be the real proving ground for whether stake-weighted voting meaningfully shifts power from large validators and the Foundation toward rank-and-file holders.
The Foundation pointed validators and delegators to the governance dashboard, the SVMGOV codebase, and the project documentation to begin participating. The launch follows a broader run of Solana Foundation institutional initiatives, including MoneyGram joining the network as a validator.
