Helius CEO and Triton One Co-Founder Clash Over SGP-0002 as Solana's Disinflation Vote Enters Final Week

With seven days until validators close their vote on SGP-0002, a detailed technical argument has broken out between two of Solana SOL$75.19-0.3%'s most prominent infrastructure figures over whether the proposal actually serves the interests of those casting the ballots.

On August 14, Triton One co-founder Brian Long published an analysis arguing that rational stakers should oppose the proposal, which would double Solana's annual disinflation rate and prevent roughly 18.9 million additional SOL from being issued over six years. Hours later, Helius hSOL$88.64-0.5% CEO Mert Mumtaz published a point-by-point rebuttal contending that Long's core reasoning contains a circular assumption and a mathematical error that reverses its own conclusion.

The formal governance vote opened August 8. As of August 13, approximately 15% of active stake supported SGP-0002, well short of the one-third quorum required for the vote to count. The deadline is August 22.

What SGP-0002 Would Change for SOL's Disinflation Schedule

SGP-0002 is the governance wrapper for SIMD-0550. If passed, it would double Solana's annual disinflation rate from -15% to -30%, compressing the timeline to reach the 1.5% terminal inflation rate from approximately 5.7 years to 2.8 years. Both paths end at the same 1.5% floor; the proposal concerns how fast to get there and how many additional SOL are issued during the transition.

Compass covered the vote opening and both competing governance proposals earlier this week in Solana Validators Debate SIMD-0550 and SIMD-0553 as SOL Issuance Cuts Near. The dispute this week is narrower: it is an argument about whether validators and stakers, acting in their rational self-interest, should support or oppose the faster disinflation path.

Brian Long's Case Against SGP-0002

Long's analysis, published to X on August 14, builds from a core premise: inflation rewards flow to stakers, not to unstaked SOL holders. His framework fixed Solana's aggregate market cap and showed that higher issuance transfers a larger fractional ownership share to stakers relative to non-stakers. He described SGP-0003's fee-burn mechanism as a sufficient and separate alternative, argued SIMD-123 would increase network revenue available to validators, and contended that under US tax treatment, higher issuance does not create additional net tax liability for stakers.

He also pointed to price history: SOL's price declined during periods when inflation was also declining, which he treated as evidence that cutting issuance would not strengthen aggregate valuation. His conclusion was that rational validators and stakers should vote NO.

Mert Mumtaz's Rebuttal: the 1.03% Gap and the Tax Claim

Mumtaz responded the same evening with a detailed thread, describing Long's framework as containing a fundamental circularity before addressing each specific claim.

On the core premise: fixing Solana's market cap assumes away the very question under debate. "You cannot prove that higher issuance maximizes wealth by assuming away its possible effect on wealth," Mumtaz wrote. He also noted that in Long's own numerical example, non-staker holdings fall in absolute terms (from $40 to $38.10), and calling this a "transfer" rather than a "loss" is a semantic distinction, not an economic one.

Even granting Long's entire framework, Mumtaz argued the math does not support Long's conclusion. Using SGP-0002's official supply paths and a 68% staking assumption, and generously assuming the same original staked cohort captures every additional emitted SOL, he calculated that stakers retain 72.395% of supply under the current inflation curve versus 71.659% under double disinflation. That 1.03% relative ownership advantage from preserving the current schedule means that if accelerated disinflation improves Solana's aggregate valuation by more than 1.03% over six years, voting YES makes even stakers wealthier on Long's own ownership-share metric.

On the tax argument: Mumtaz disputed Long's "no leaky bucket" claim. Under current IRS guidance, cash-method US taxpayers include staking rewards in gross income at fair market value when they gain control over them. The IRS does not subtract the portion that merely compensates for dilution. Higher nominal issuance can therefore produce a larger tax liability even when much of the apparent income only maintains the staker's real ownership share.

Mumtaz also rejected the framing of SGP-0003 as an alternative, describing the two proposals as complementary. Burning a new resource fee paid by users does not answer whether the protocol should also issue 18.9 million additional SOL to subsidize stakers. On SIMD-123, he was direct: the proposal redistributes existing block revenue between validators and delegators but does not increase Solana's total network revenue.

His final point addressed the shared terminal rate. Since both inflation schedules converge at 1.5%, if 1.5% inflation were ultimately insufficient to secure the network, the current schedule reaches that same endpoint regardless. The debate then concerns only the transition speed, not any difference in long-run security economics.

What the Vote Requires to Pass

Passage requires two thresholds: quorum from at least one-third of Solana's active stake, and two-thirds of votes cast in support. At approximately 15% of active stake supporting and seven days remaining as of publication, both thresholds are unmet.

One concern not fully addressed in the public debate appears in the SIMD-0550 proposal itself: accelerating disinflation reduces staking yields and could render approximately 30 small validators unprofitable by the third year of the new schedule, raising questions about validator concentration that sit outside the staker-wealth argument both sides debated publicly.

SGP-0003, the companion proposal wrapping SIMD-0553's fee burn, is tracking on a separate timeline.
