Solana’s (SOL) first binding on-chain governance process ended with a razor-thin decision on token issuance. After days of stake-weighted voting, validators and delegators approved SGP-0002, the so-called Double Disinflation measure, by a margin of roughly one-third of a percentage point.
The proposal needed a two-thirds supermajority of participating stake.
It finished near 67 percent support, just above the 66.67 percent cutoff.
The vote was part of a three-item package that also included a governance constitution and a separate fee-burn overhaul.
The constitution passed easily.
The fee plan did not. SGP-0002 was the closest and most closely watched of the three.
Under Solana’s existing monetary schedule, new SOL creation already declines each year.
The annual reduction rate had been 15 percent, with issuance designed to settle at a long-run floor of 1.5 percent around 2032. SGP-0002 doubles that yearly reduction to 30 percent.
The 1.5 percent floor stays the same.
What changes is the speed of the approach.
Modelers tied to the companion technical document, SIMD-0550, estimate the network would reach the floor around 2029 instead, shortening the path from about 5.7 years to about 2.8 years after activation.
Authors of the measure, including Helius contributors Lostin and 0xIchigo, project that the steeper schedule would keep about 18.9 million SOL from being issued over the next six years, or roughly 2.6 percent less supply than the prior path implied.
Supporters framed that as lower dilution for holders who do not stake.
Critics, including several large staking operators, argued that inflation also funds validator and delegator rewards, and that compressing those rewards too quickly could weaken the incentive to secure the chain.
The arithmetic of the ballot was dramatic.
About 176.29 million SOL voted in favor, 66.19 million against, and 20.63 million abstained.
Participation reached about 60.7 percent of the eligible snapshot of roughly 433.5 million SOL, well above the one-third quorum.
More than 1,300 validators took part, the highest turnout yet for an on-chain Solana governance vote.
Hours before the window closed, the measure looked likely to fail.
A Kraken-linked validator that had cast a large block against the proposal later shifted most of that stake to yes.
Galaxy-linked validators also moved from mostly abstaining toward support.
Helius chief executive Mert Mumtaz said he spent the final stretch calling operators and that the last votes arrived in the closing seconds.
Passage is a mandate, not an instant protocol change.
Client teams still have to implement SIMD-0550, coordinate feature gates, and activate the new schedule on-chain.
Until then, issuance follows the old 15 percent disinflation path.
Once live, staking yields are expected to compress as inflation falls faster, a trade-off the community has now formally accepted.
The result also tests Solana’s new SGP system, which lets stake holders, and in some cases delegators who override their validators, record directional decisions on protocol economics. After an earlier inflation-related vote failed in 2025, this one cleared, but only just. That sliver of support will now have to survive the slower work of engineering and activation.
