Two Solana governance proposals have crossed the 15% stake-support threshold required to advance, triggering a discussion period that runs through August 22, 2026, ahead of binding votes on token supply and fee structure reforms.
SGP-0002 and SGP-0003 entered their live governance clock after major stakeholders including Helius and Jupiter signaled backing. Helius, the largest named supporter of both proposals, committed 16 million SOL to their advancement. Jupiter, the second-largest named supporter, backed both with 12.47 million SOL.
Mert Mumtaz, CEO of Helius, described the milestone as “the first step on the road to discussion and a final on-chain vote.”
SGP-0002: Accelerated Disinflation
SGP-0002 doubles the annual disinflation rate from 15% to 30% while maintaining a 1.5% terminal inflation target. Under the current path, Solana reaches that terminal rate in 5.7 years. The proposal compresses that timeline to 2.8 years.
The accelerated curve would reduce token issuance by 18.9 million SOL across six years, representing a 2.6% decrease relative to the baseline schedule.
Staking yields decline as issuance falls. At baseline, staking yield stands at 5.84%. After one year under SGP-0002, yields drop to 4.34%. After two years, they fall to 3%, and after three years, to 2.25%.
Validator profitability margins tighten under the proposal. The number of unprofitable validators rises from 290 at baseline to 292 after one year, 303 after two years, and 320 after three years.
SGP-0003: Fee Structure Redesign
SGP-0003 replaces the current 50/50 signature-fee split, in which half of fees are burned and half flow to block leaders, with a new two-tier structure.
The proposal introduces a 2,500-lamport inclusion fee paid entirely to the leader. The current base fee per signature is 5,000 lamports. Separately, a usage-based resource fee would be burned in full, with rate steps at 0.1, 0.25, and 0.5 lamport. Priority fees continue flowing to block leaders under the redesign.
Daily burns would increase substantially. At the first resource-fee rate using May 2026 data, estimated daily burns range from 1,500 to 1,800 SOL. At the terminal resource-fee rate, estimated daily burns rise to 7,500 to 9,000 SOL. Current daily signature-fee burns total 648 SOL.
Resource-heavy or loosely budgeted transactions could face higher fees under the new structure, shifting cost burden onto computing resources requested rather than flat signature counts.
Next Steps
The discussion period ends at 15:13 UTC on August 22, 2026. Implementation and feature-gating would follow any successful vote before on-chain economics change.
