Solana governance clock starts for two supply reforms

Two Solana supply proposals, SGP-0002 and SGP-0003, advanced past the 15% stake-support threshold and are now in a formal governance discussion that runs until Aug. 22, 2026, 15:13 UTC. After the discussion window closes, each proposal must pass a separate on-chain vote before any code changes or feature gates are implemented. Named supporters Helius and Jupiter staked about 16 million SOL and 12.47 million SOL respectively to move the measures into the discussion phase.

SGP-0002 targets token issuance by increasing the annual disinflation rate from 15% to 30% while keeping the protocol’s 1.5% terminal inflation target and the existing reward mechanism. Proposal modeling shows the network reaching the 1.5% inflation point in roughly 2.8 years under the change, compared with about 5.7 years on the current path. Over a six-year span the model projects about 18.9 million fewer SOL issued, equivalent to approximately a 2.6% reduction in projected issuance under the proposal’s assumptions.

The proposal’s modeled issuance path reduces staking rewards over time. Under an assumed 68% staking participation rate, modeled yields begin near 5.84% and decline to about 4.34% after one year, 3.00% after two years and 2.25% after three years; those figures exclude commissions, MEV and block leader rewards. The same model estimates the number of unprofitable validators rising from 290 at baseline to 320 after three years, noting those counts depend on SOL price, operator costs, validator commission rates and voting behavior.

SGP-0003 restructures fees by separating an inclusion fee from a usage-based resource fee and burning the resource fee in full. Under the current structure, the base signature fee of 5,000 lamports is split 50/50 between burning and the block leader. The proposal would replace that with a 2,500-lamport inclusion fee paid entirely to block leaders and a per-requested-cost-unit resource fee that is burned; priority (tip) fees would continue to go to block leaders.

The resource fee would phase through three rates: 0.1, 0.25 and 0.5 lamport per requested cost unit. Using May 2026 network throughput data and the proposal authors’ assumptions, estimated daily burns range from about 1,500 to 1,800 SOL at the first rate and from roughly 7,500 to 9,000 SOL at the terminal rate. Current signature-fee burns average about 648 SOL per day; the terminal upper-end estimate would exceed that by more than 1,200%. The authors note that transactions that budget resources efficiently could cost less under the new fee structure, while resource-heavy or loosely budgeted transactions could pay more.

The governance interface marks proposals ready for debate once they meet the 15% stake threshold; the discussion outcome is not binding. Any implementation would require a successful on-chain vote and feature-gating before the network’s on-chain economics change. Helius chief executive Mert Mumtaz described the milestone as “the first step on the road to discussion and a final on-chain vote.”

Token burns reduce net issuance and lower inflationary pressure on the supply. Faster disinflation and larger burns change how issuance and fees are allocated among staked rewards, transaction payers and block leaders. The eventual on-chain effects will depend on final vote outcomes, SOL price, network usage and operator costs.
