Solana completed its first binding on-chain governance vote on Aug. 27-28, 2026, replacing validator-only off-chain signaling with stake-weighted voting under the Solana Governance Proposal framework. SGP-0001, the Solana Constitution, received about 86% support, and SGP-0002, or Double Disinflation, passed with 67.00% support, roughly 0.33 percentage points above the two-thirds threshold. The measure doubles annual disinflation from 15% to 30%, moving Solana toward its 1.5% terminal inflation rate around 2029 instead of about 2032 and reducing projected issuance by approximately 18.9 million SOL over six years. SGP-0003, the Resource and Inclusion Fee proposal, received 53.90% support and more support than opposition but failed after abstentions counted in the approval denominator; the source records 27.18% abstention and separately reports about 72 million SOL abstaining. The proposal would have replaced part of Solana’s fixed signature fee with a resource-based fee burned in full. No new vote has been scheduled, although the measure could return in revised, narrower form. The governance vote coincided with a sharp SOL rally and strong inflows into SOL-related ETFs.
