Solana validators narrowly approved a proposal to double the pace at which new SOL issuance falls, in a vote that sat below the required majority until its closing minutes. SGP-0002, known as Double Disinflation, finished Friday with 67% support against a 66.667% threshold.

Participation reached 60.7% of eligible stake across 1,326 validators, well above the one-third quorum. About 25% voted against and 7.84% abstained. The measure raises Solana’s annual disinflation rate from 15% to 30% while leaving the long-term 1.5% inflation target unchanged, reaching that floor in roughly 2.8 years instead of 5.7, or early 2029 rather than 2032. Projected issuance falls by about 18.9 million SOL over six years.

Lower issuance means less dilution for holders and thinner rewards for the validators securing the network, which is why the vote divided large stakeholders instead of uniting them. Solana had rejected a more aggressive issuance cut in March 2025, when SIMD-228 drew a majority but missed the supermajority.

The margin for SGP-0002 came from late switches. Kraken’s validator, representing about 8.9 million SOL, moved against the proposal with hours left and dropped support below the bar, then shifted roughly 8.1 million SOL back to yes. Galaxy, holding about 1.7% of the vote weight, went from near-total abstention to majority support. Helius voted 16.05 million SOL at a 99.5% yes rate; Figment voted 17.07 million SOL against and Everstake 7.96 million against.

SGP-0002 is a governance mandate rather than a live protocol change: the implementation, SIMD-0550, still has to be shipped by client teams and activated on-chain. Two companion measures shared the ballot. SGP-0001, the governance framework itself, passed comfortably. SGP-0003, which would have introduced resource-based fee pricing and promised to burn roughly 7,500 SOL a day, drew 53.9% and failed.
