Two governance proposals, SIMD-0550 and SIMD-0553, are advancing through the network’s voting process this week, and together they represent the most aggressive tokenomics overhaul Solana has attempted since the failed SIMD-0228 vote in early 2025. What SIMD-0550 and SIMD-0553 actually doSIMD-0550, submitted on June 2, 2026, by Helius engineer lostintime101, doubles the annual disinflation rate from 15% to 30%. Solana’s inflation rate currently decreases by 15% each year, slowly grinding down toward a terminal rate. At the current pace, reaching that terminal rate takes roughly 5.7 years. Under current conditions, the network burns roughly 650 SOL per day.
