Solana validators just voted to put SOL on a diet. The network’s governance body approved SGP-0002, a proposal that doubles the annual disinflation rate from 15% to 30%, meaning the amount of new SOL entering circulation will shrink twice as fast as originally planned. The move pulls forward Solana’s target for hitting its 1.5% terminal inflation floor from roughly 2032 to 2029, three years ahead of schedule.
The vote closed on August 28 with 176.29 million SOL in favor and 66.19 million opposed, landing at 67% approval. That barely cleared the two-thirds supermajority required, and the outcome reportedly hinged on the Kraken validator switching its position before the deadline.
What the numbers actually mean
The approved proposal, which implements SIMD-0550, will prevent an estimated 18.9 million SOL from being minted over the next six years.
Solana’s inflation rate as of June 2026 sat at approximately 3.82%, with staking participation hovering around 68%. Under the old schedule, the network would have gradually tapered issuance over the next six-plus years. Under the new plan, that taper happens roughly twice as fast.
