A new Solana governance proposal wants to double the speed at which the network’s inflation rate declines, a move that would eliminate roughly $1.5 billion in future SOL token emissions at current prices. SIMD-0550, submitted by Helius engineer lostintime101, has already picked up public backing from Solana Labs co-founder Anatoly Yakovenko.

The core mechanic is straightforward. Solana’s inflation schedule currently decreases by 15% each year, gradually working its way toward a long-term terminal rate of 1.5%. SIMD-0550 would crank that annual decline to 30%, keeping the starting rate at 8% but reaching the finish line in roughly 2.8 years instead of 5.7.

What the proposal actually changes

Solana’s current inflation model was designed with a built-in decay curve. Each year, the rate at which new SOL enters circulation drops by 15%, slowly tapering from a high initial rate down to the 1.5% floor.

SIMD-0550 doesn’t touch the starting point or the destination. It only changes the speed of the journey. By doubling the annual disinflation rate from 15% to 30%, the proposal compresses the timeline dramatically.
