DescriptionSIMD-550, submitted in early June 2026 by Helius engineers (Lostin and 0xIchigo), proposes doubling Solana's annual disinflation rate from 15% to 30%, accelerating the path to the 1.5% terminal inflation rate from ~5.7 years to ~2.8 years. As of June 22, Anza CEO confirmed it is 'on track for this year.' A formal on-chain vote requires scheduling by core development teams under the SGP1 governance framework, which includes a 10-epoch discussion period after a 15% threshold is met.
This event resolves YES if an official on-chain epoch/date for the SIMD-550 governance vote is publicly announced on or before July 20, 2026 UTC. Resolves NO if no formal scheduling announcement is made by that deadline.
1. Specificity: A formal scheduling announcement (official epoch or calendar date for the vote) must be made by core devs or the Solana Foundation.
2. Exclusion: Community sentiment polls, Discord discussions, or informal indications do NOT count.
3. Source Hierarchy: Helius blog (helius.dev) primary. Solana Foundation official channels secondary. Anza announcements tertiary.
4. Timing: Must occur before July 20, 2026 23:59 UTC. Post-deadline resolves NO.
5. Cancellation Rule: Proposal withdrawal or merger into another SIMD before deadline resolves NO.
