Solana Validators Approve Double Disinflation — SGP-0002 Doubles Annual Rate from 15% to 30%

Solana validators approved SGP-0002 on August 28, 2026, doubling the network's annual disinflation rate from 15% to 30%. The proposal passed at epoch 1024 with 68.77% support, meaning terminal inflation arrives around 2029 instead of 2032 and roughly 18.9 million fewer SOL will enter circulation over the next six years.

Solana just completed its first binding on-chain governance vote, and the results are mixed but consequential. Three proposals went to stakeholder vote, and two passed while a third fell short. The centerpiece, SGP-0002, accelerates how quickly new SOL issuance drops toward the network's long-term floor of 1.5% annual inflation. The constitution proposal (SGP-0001) sailed through at 95.35%. A separate fee-burn overhaul (SGP-0003) didn't clear the two-thirds threshold at 62.72%.

The vote closed at epoch 1024 after running longer than expected because Solana epochs track block production, not wall-clock time. Participation across all three proposals hovered around 47–60% of eligible stake, depending on the measure.

Key Takeaways

• SGP-0002 doubles disinflation from 15% to 30%, reaching terminal 1.5% inflation by 2029 instead of 2032
• ~18.9 million fewer SOL issued over six years, reducing dilution for existing holders
• SGP-0001 (Constitution) passed at 95.35% support
• SGP-0003 (Fee Burn) failed at 62.72%, below the two-thirds threshold
• Figment voted against; Helius, Jupiter backed yes; Kraken flipped from no to yes
• A passed SGP is a mandate, not an immediate network change—separate SIMDs still required

What SGP-0002 Actually Changes

Solana currently disinflates at 15% per year, gradually reducing new emissions until hitting a 1.5% long-term floor. SGP-0002 doubles that rate to 30% annually. The terminal target doesn't move. Only the speed does.

Under the old schedule, the network would reach that 1.5% floor around mid-2032. The new schedule puts it at mid-2029. Helius modeled the difference at roughly 18.9 million fewer SOL emitted over the next six years. At August 2026 prices around $103, that translates to about $1.51 billion in reduced emissions.

The proposal itself came from Solana researcher Lostin and developer 0xIchigo, who published their analysis through Helius in June 2026 as SIMD-550. It updated an earlier version (SIMD-411) that had gone stale while the ecosystem waited for governance tooling that let stakers vote alongside validators.

The Vote Split Among Top Voters

The result wasn't a consensus run. Several of the largest validators took opposite sides.

Figment, the biggest single voter with about 17.1 million SOL staked, voted entirely against. Austin Federa, formerly head of strategy at the Solana Foundation and now at DoubleZero, publicly advocated for the fee-burn proposal (SGP-0003) and framed the disinflation vote as part of a broader tokenomics push that he supported—yet Figment still cast its stake against SGP-0002.

Helius and Jupiter, two of the other major validators, overwhelmingly backed the measure. Kraken's position shifted mid-vote. The exChange initially voted no at 12:33 UTC, briefly pushing support below the threshold. By the time voting closed, roughly 90% of Kraken's ~8.9 million SOL in voting stake had flipped to yes. That movement was close to what kept the proposal over the line.

Solana Company, the Nasdaq-listed SOL treasury firm trading under ticker HSDT, said on August 21 it would vote for the constitution but against both SGP-0002 and SGP-0003, citing a need for predictable economic rules when making multi-year treasury decisions.

Why Validators Pushed for Faster Disinflation

The Helius research note laid out four arguments for accelerating the disinflation schedule.

First, they argued the original job of inflation is done. High emissions made sense when Solana needed to bootstrap stake distribution, reward early validators, and seed participation. By 2026, the network has institutional investors, enterprise adopters, and deep developer presence. Continued high issuance mostly adds selling pressure without the compensating demand that bootstrapping used to generate.

Second, they pointed to what they called a "leaky bucket." Stakers in certain jurisdictions treat rewards as ordinary income and sell portions to cover taxes. Max Resnick calculated this creates roughly a 17% effective tax drag on inflation—the gap between ordinary income rates and the 20% long-term capital ga
