Helius researcher releases proposal to increase Solana’s deflationary rate from -15% to -30%

Helius released a research article stating that Solana’s inflation adjustment proposal, SIMD-550, recommends increasing the inflation deceleration rate from -15% to -30%, thereby shortening the time required to reach the long-term inflation target of 1.5% from approximately 5.7 years to 2.8 years. Modeling estimates indicate that this proposal would reduce SOL issuance by roughly 18.89 million tokens over the next six years—equivalent to approximately $1.51 billion at current prices.
