Solana validators pass 30% disinflation plan in photo-finish vote

Solana validators approved SGP-0002, doubling the network's annual disinflation rate to 30 percent, after a last-minute validator reversal carried the measure with 67 percent support.

"After 500 calls in the past few hours, we got all the votes in the last seconds and passed the disinflation proposal by a literal hair," Mert Mumtaz, chief executive of Solana infrastructure provider Helius, wrote on X.

The "Double Disinflation" proposal keeps Solana's 1.5 percent terminal inflation target unchanged but accelerates the path to it, cutting the timeline to roughly 2.8 years from about 5.7 years. That implies about 18.9 million fewer SOL issued over the next six years, worth roughly $1.47 billion at current prices. Final tallies showed 176.29 million SOL for, 66.19 million against and 20.63 million abstaining, with turnout reaching 60.7 percent of eligible stake.

The change tightens SOL's supply schedule and reduces dilution for holders, but it lowers staking rewards for validators and delegators. A 21Shares analysis projected staking yields could fall to about 2.25 percent within three years from roughly 5.25 percent today.

The outcome hinged on late shifts among large validators. Figment, the largest voter in the finalized data with 17.1 million SOL staked, voted entirely against the measure, while Helius and Jupiter overwhelmingly backed it. Kraken's larger validator, holding about 8.9 million SOL, initially voted against at 12:33 UTC, temporarily pushing support below the 66.67 percent threshold. It recast at 10:37 UTC as 90.34 percent for and 9.66 percent against, moving roughly 8.1 million SOL. Galaxy Digital also shifted from mostly abstaining to majority yes near the deadline.

Kraken co-CEO Arjun Sethi said custody service providers should not be the determining actors in such decisions. The vote was part of Solana's first binding governance cycle, which also approved a proposed Solana Constitution with 95.35 percent support while rejecting a separate fee-burn proposal with 53.9 percent.

The referendum grants a mandate but does not immediately change SOL's monetary schedule. Implementation requires deploying the SIMD-0550 technical upgrade, a process expected to take at least 4.5 months as validators coordinate client adoption and feature gating.

The governance decision landed as US-listed Solana investment products keep drawing capital. Bitwise's Solana ETF surpassed $1 billion in assets, the first Solana ETF to reach the milestone, and US Solana ETFs have accumulated roughly $1.7 billion in cumulative net inflows since launch, according to Bloomberg ETF analyst Eric Balchunas. SOL traded near $106 following the vote, down about 1.2 percent over the prior 24 hours, after climbing more than 8 percent in a single day earlier in the week.

The faster path to terminal inflation reshapes the trade-off between dilution and staking income, a debate playing out across mature proof-of-stake networks. As the capital securing Solana grows, the network is betting it can issue less while keeping validators aligned, with the first-year staking yield projected at 4.34 percent under the accelerated schedule against 4.93 percent under the existing one.
