SIMD-0228 proposes a programmatic, market-based emission mechanism for Solana, adjusting token emissions based on staking participation rates.
The proposal details are available in the SIMD repository and the Solana governance forum.
Pass Threshold
For SIMD-0228 to pass, at least 66.66% of Yes + No votes must be in favor ("Yes").
This means that abstentions do not affect the threshold directly, but a high number of "No" votes can prevent the proposal from passing.
