Solana validators narrowly approved a proposal to accelerate the decline in new SOL issuance, passing the measure in the network’s first system-wide governance vote. SGP-0002, called Double Disinflation, finished Friday with 67% support, only slightly above the 66.667% threshold required for approval.
Participation reached 60.7% of eligible stake across 1,326 validators, comfortably above the one-third quorum. About 25% voted against the proposal, while 7.84% abstained.
Issuance decline will speed up, but the 1.5% target stays in place
The proposal lifts Solana’s annual disinflation rate from 15% to 30% without changing the network’s long-term 1.5% inflation target. Under that schedule, Solana would reach the floor in roughly 2.8 years instead of 5.7 years, or in early 2029 rather than 2032.
Projected issuance would drop by about 18.9 million SOL over six years. Lower issuance reduces dilution for token holders, but it also cuts into the rewards earned by validators securing the network. That split helps explain why large stakeholders did not line up on one side of the vote.
Late vote changes decided the outcome
Support for SGP-0002 stayed below the required majority until the closing stretch. The final margin came from late reversals by major validators.
Kraken’s validator, representing about 8.9 million SOL, switched against the proposal with hours remaining and pushed support below the line. It later moved roughly 8.1 million SOL back to yes. Galaxy, which held about 1.7% of the vote weight, shifted from near-total abstention to majority support.
Other large votes broke sharply across both sides. Helius cast 16.05 million SOL with a 99.5% yes rate. Figment voted 17.07 million SOL against, and Everstake voted 7.96 million SOL against.
Approval is a governance mandate, not a live protocol change
According to Unchained, SGP-0002 authorizes the policy direction but does not by itself activate a protocol change on Solana. The implementation proposal, SIMD-0550, still needs to be shipped by client teams and then activated on-chain.
Two related measures were also on the ballot
Validators also voted on two companion proposals. SGP-0001, which establishes the governance framework itself, passed comfortably. SGP-0003, a proposal that would have introduced resource-based fee pricing and was expected to burn roughly 7,500 SOL per day, received 53.9% support and failed.
The vote followed an earlier rejection in March 2025, when Solana considered a more aggressive issuance cut under SIMD-228. That proposal won a majority but fell short of the required supermajority.
