Solana concluded its first binding on-chain governance cycle with two of three proposals clearing the two-thirds bar: the Solana Constitution (SGP-0001) passed with 85.97% support and Double Disinflation (SGP-0002) passed at exactly 67.00%, while the Resource and Inclusion Fee proposal (SGP-0003) failed at 53.90%. All three votes met the one-third stake participation quorum, with overall participation near 60.7%. SGP-0002 doubles the annual disinflation rate from 15% to 30% while keeping the 1.5% terminal inflation floor, shortening the path to that floor from about 5.7 years to 2.8 years under SIMD-0550 and cutting projected SOL issuance by roughly 18.9 million tokens, or about 2.6% versus the prior schedule, over six years. Official tallies showed 176.29 million SOL in favour, 66.19 million opposed, and 20.63 million abstaining. Support sat below 66.67% for much of the final hour before large validators reversed; Kraken’s validator, with about 8.92 million SOL of voting power, flipped from no to yes, and post-vote arithmetic indicated the measure would have finished near 63.9% without that switch. Validators linked to Galaxy Digital and Drift Protocol also flipped late. Helius chief executive Mert Mumtaz said he made roughly 500 calls in the closing hours. The referendum is a political mandate, not an automatic code change: developers must re-anchor the supply curve, test the schedule, and activate a feature gate through SIMD-0550, a process estimated at least 4.5 months, so daily inflation does not shift immediately. Under the new path, nominal staking yield is projected near 4.34% in year one, 3% in year two, and 2.25% in year three, versus about 5.25% currently. SGP-0001 formalizes future proposal rules and activates the svmgov program. SGP-0003 would have split the 5,000-lamport signature fee into a fixed inclusion fee and a burnable resource fee, with modeling of much higher daily SOL burns, but heavy abstentions sealed its failure. Nasdaq-listed Solana Company backed the constitution and opposed both economic measures. SOL traded around $106.62, down about 3% over 24 hours and up 10.1% over the week.
