SGP-0002: vote passed, SIMD-0550 still to activate logoSGP-0002: vote passed, SIMD-0550 still to activate
SGP-0002 passed 28 Aug 2026. The schedule still waits on SIMD-0550 in Agave and Firedancer, then a feature gate. Inflation slope doubles. Terminal 1.5% stays.
devrels.xyz/a/205SGP-0002 closed on 28 August 2026. Stake endorsed doubling Solana’s yearly disinflation from 15% to 30%. SIMD-0550 is the code that actually turns that slope. Client teams still have to ship it, then validators activate the feature gate.
Until that gate is on, new SOL keeps following the old schedule. App yield copy, LST docs, and treasury models should wait for the gate, then swap the inflation path.
Vote tally (28 Aug 2026)
Snapshot from public reports of the governance.solana.com close. Abstentions count toward quorum. The approval percentage is For divided by (For + Against). The bar was two-thirds of that, or 66.667%.
| Figure | Value |
|---|---|
| For | 176.29M SOL (67.001% of For+Against) |
| Against | 66.19M SOL |
| Abstain | 20.63M SOL |
| Eligible stake that voted | 60.7% (quorum was one-third) |
| Margin | 0.334 points over 66.667% |
Same session: SGP-0001, the governance constitution, passed with about 95% support. SGP-0003, the fee-burn overhaul, stayed under two-thirds. That fee change is a separate SIMD track.
What the schedule does
Inflation is the yearly pace of new SOL. Disinflation is how fast that pace falls each year. Double disinflation turns the yearly reduction from 15% to 30%. Starting rate (historically 8%) and the 1.5% terminal floor stay put. The path to 1.5% shortens from about 5.7 years to about 2.8 years from mid-2026 modeling, so terminal lands around H1 2029 instead of H1 2032.
Public write-ups put the six-year emissions cut near 18.9 million SOL. That is future mint, not a burn of balances already in wallets.
What builders do now
- Watch Agave and Firedancer release notes for the SIMD-0550 feature gate. The vote is the mandate. The gate is the switch.
- Point APY UIs at a live source. Inflation APY will compress earlier once the gate is on. Fee and MEV share stay a separate line.
- Update LST and stake-pool copy that quotes a sticky inflation yield.
- Run treasury scenarios on both slopes until activation date is public.
Program code for ordinary dapps does not change for this parameter. Assumptions in yield UX do.

Solana's protocol votes used to be ad hoc SPL-token ballots coordinated off chain. As of July 2026 there is standing machinery: two mainnet programs, a fixed 11-epoch lifecycle, Merkle-proof-verified stake weights, and a staker sovereignty mechanism that lets delegators overrule their validator's vote with their own stake. Here is how the SGP system works end to end, how it differs from SIMDs, and what is already queued to vote.
