Solana’s Emissions Reform: Approved, and What Happens Next
Solana's stake-weighted vote on SIMD-0550 closed on 28 August 2026, approving a doubling of the rate at which network inflation falls. Staking rewards have not changed yet, because the proposal still needs to be activated through a feature gate and no date has been set.
This report sets out what happens when it is. It covers the effect on delegator rewards and the revised path to Solana's 1.5% inflation floor, why the rejection of SIMD-0553 leaves transaction fees and validator vote costs where they are, and how shorter epochs under SIMD-0525 change the cadence of stake activation and withdrawal. It includes Twinstake's own measurement of Solana mainnet across 37,365 transactions, and revised supply modelling now that only one of the two proposals has passed.
Download the report to understand what the approved change means for staking rewards, when it will take effect, and what institutional stakers should be watching for.

This report traces Solana's infrastructure transformation over the past five years, from an operationally immature network into one of the most competitive venues for on-chain high-frequency trading.
It follows that journey chronologically: the early years in which validator performance was largely indistinguishable, the memecoin-driven demand shock of 2024 that exposed latency as the critical bottleneck, and the emergence of an execution layer built around MEV extraction, transaction routing and shred propagation. Client diversity, XDP kernel-bypass networking and the Alpenglow consensus overhaul are now closing the gap with centralised trading venues.
Download the report to learn why validator selection, transaction routing and staking strategy are increasingly connected decisions for institutions, and what that means for due diligence.
