Solana validators and delegators are voting on two proposals that could accelerate SOL disinflation and increase transaction‑fee burns. SIMD‑0550 would double the annual disinflation rate from 15% to 30% while keeping the network’s 1.5% terminal floor unchanged, potentially reducing issuance by about 18.9 million SOL over six years, a reduction valued at roughly $1.4‑$1.5 billion according to 21Shares estimates. SIMD‑0553 would modify transaction fees by replacing a 5,000‑lamport per‑signature base fee with a 2,500‑lamport inclusion fee paid to the block leader and a burned resource fee; the resource fee could rise through three feature gates to one‑half lamport per requested cost unit, potentially raising daily burns from about 648 SOL to 7,500‑9,000 SOL at current activity, a twelve‑ to fourteen‑fold increase. The proposals are catalogued as SGP‑0002 (SIMD‑0550) and SGP‑0003 (SIMD‑0553) in Solana’s improvement‑document repository. Voting runs through epoch 1023, expected to close around 15:30 UTC on August 27, though epoch timing may shift. Approval would constitute a governance mandate rather than an immediate activation; code, testing, validator coordination and staged feature‑gate scheduling would still be required before any changes take effect. The final vote must achieve participation from at least one‑third of total stake and support from two‑thirds of participating stake, excluding abstentions. Solana Company, a Nasdaq‑listed SOL treasury operator, voted against both proposals, arguing that altering core parameters could complicate institutional revenue and cost forecasting; the firm earned $2.512 million from staking in Q2, making lower issuance directly relevant to its business. Nominal staking yields could decline from roughly 5.25% to 4.34% in the first year, 3% in the second and 2.25% in the third under the faster schedule. The fee redesign was merged into the repository on July 20 after review by Anza and Firedancer teams, and implementation is expected in version 4.3 following testing. The ultimate effect on SOL supply will depend on activation timing, SOL price, validator economics and future network demand.
