Helius researcher releases proposal to increase SOL's anti inflation rate from -15% to -30% BlockBeats News: On June 17th, Helius researchers released a proposed proposal SIMD-550, suggesting updating Solana's inflation plan to increase the anti inflation rate from -15% to -30%, doubling the rate of inflation decline. This will bring inflation to a long-term ultimate rate of 1.5% within 2.8 years (first half of 2029), instead of 5.7 years (first half of 2032). According to their model, this proposal will reduce the issuance of 18.89 million SOLs worth approximately $1.51 billion over six years, while gradually lowering nominal pledge yields from approximately 5.84% to approximately 4.34%, 3.00%, and 2.25% over the first three years. It is expected that the doubling of inflation will have a limited impact on the number of profit validators. In the first year, 2 validators will turn from profit or flat to loss, 13 in the second year, and 30 in the third year. SIMD-550 is an updated version of SIMD-411 (November 2025), which was discontinued due to the ecosystem waiting for new tools. SIMD-550 can be seen as part of a broader effort to improve the economics of SOL tokens. Other parts include SIMD-553, proposed additional resource costs for combustion, and Alpenglow's verifier admission ticket (VAT). [Original link]
