Wu Shuo learned that Helius published a research article stating that the Solana proposal SIMD-550 suggests increasing the inflation decline rate from -15% to -30%, bringing the long-term terminal inflation rate to approximately 1.5% in the first half of 2029, rather than the current plan of the first half of 2032. The model shows that this proposal is expected to reduce the issuance of 18.89 million SOL over the next six years, equivalent to about $1.51 billion; the nominal staking yield will gradually decrease from the current approximately 5.84% in the first three years to about 4.34%, 3.00%, and 2.25%. The article states that this proposal has limited impact on the number of profitable validators, with an estimated 2, 13, and 30 validators transitioning from profit or breakeven to loss in the first to third years.
