Solana Approves Double Disinflation Proposal With 67% Support

Solana validators have approved SGP-0002, known as “Double Disinflation,” in the network’s first successful binding on-chain governance vote. The proposal received 67.001% support, doubling the annual disinflation rate from 15% to 30% and accelerating the network’s path toward lower issuance.

Governance Vote Clears Key Threshold

The vote recorded 176.29 million SOL in favor, 66.19 million against, and 20.63 million abstaining. Participation reached 60.7% across 1,326 validators, making the decision one of the most consequential governance actions in Solana’s history.

The final result was shaped by several late changes in validator positioning:

• Kraken-linked validators, representing roughly 2% of total voting weight, moved from opposition to support.
• Galaxy validators shifted from abstention to majority support, contributing approximately 1.7% of voting weight to the approval side.
• Figment and Everstake opposed the proposal, warning that faster disinflation could reduce staking yields and validator rewards.

The proposal was authored by Helius engineers Lostin and 0xIchigo, with support from Helius and Jupiter. About one-third of participating stake either opposed or abstained, leaving validator economics as a central concern despite the proposal’s passage.

Issuance Schedule Moves Faster

Solana’s inflation model reduces issuance by a fixed percentage each year until it approaches a terminal rate. The approved change does not alter that terminal rate, which remains 1.5%, but it causes the network to reach that level substantially sooner.

Under the previous schedule, Solana was expected to reach the terminal rate around H1 2032. The new schedule targets approximately H1 2029, compressing the timeline from roughly 5.7 years to 2.8 years based on the proposal’s projections.

The network is currently running at approximately 3.82% inflation, with around 68% of SOL staked. Over the next six years, the accelerated schedule is expected to prevent the issuance of an estimated 18.9 million SOL. That represents a 2.6% lower supply trajectory than under the previous plan.

The change is not a token burn. Instead, the SOL will never be minted and therefore will not be distributed through staking rewards under the old schedule.

What This Means

The vote strengthens Solana’s ability to use network-wide governance to modify core economic parameters. A previous attempt, SIMD-228, failed in March 2025, making this approval an important test of validator coordination and voting legitimacy.

For SOL holders, faster disinflation may support a tighter long-term supply profile, although the market impact will depend on demand, staking participation, and network activity. For validators and delegators, the trade-off is potentially lower future rewards. The decision therefore marks both a supply-side adjustment and a new precedent for how Solana balances token scarcity with network security incentives.
