They attack the same problem from opposite ends. One slows how fast new SOL is printed, the other speeds up how fast existing SOL is destroyed. Both need 15% of staked SOL (64.90M) to advance to a full vote by August 18.
Solana's inflation rate shrinks every year. Today it shrinks 15% annually. This doubles it to 30%, reaching the 1.5% terminal rate in ~2.8 years instead of ~5.7.
Reworks how Solana charges for blockspace, splitting fees into a resource cost and an inclusion cost. The effect: far more of what the network already collects gets burned, scaling with real usage.
Drag the burn slider. The model steps month by month: inflation decays toward the 1.5% floor and re-anchors at activation exactly as SIMD-0550 specifies, and burns are subtracted daily. Hover either chart for the numbers at any point in time.

Not today, and not at the base case. But the gap closes from both sides, and that's the part almost nobody is modelling.
Solana issues roughly 65,500 SOL per day. The base case burns 9,000. Even then ~56,500 new SOL still hits the market daily. Burns would need to grow another 7x overnight to flip it, and that isn't happening in 2026.
Under SIMD-0550 inflation hits the 1.5% floor in ~2.8 years, and daily issuance falls toward ~27,000 SOL. From there burns only need to roughly triple from the base case, plausible if RWAs and tokenized equities land on Solana. The threshold is about 26,900 SOL/day. Set the slider to 30,000: the second chart shows supply starting to shrink in early 2029.
Pick a valuation you think Solana could reach in 2032, divide by the supply that exists then, and you get a price per SOL. Fewer tokens means the same valuation buys a higher price. Updates live with the burn slider.

If you've never cared about tokenomics, this is the whole thing in four steps.
About 65,500 SOL per day. That's the reward validators and stakers earn for securing the network, and it's also new supply hitting the market.
Inflation started at 8% and falls 15% per year until a 1.5% floor, which takes until roughly 2032. SIMD-0550 doubles the shrink rate to 30% and pulls that into 2029.
Only 650 SOL a day burns today, around $48K. Solana processes billions in volume and captures almost none of it permanently. SGP-0003 changes that.
Less printed, more burned. Issuance falls on a fixed schedule; burns rise with usage. If both hold, they meet, and SOL starts destroying more than it creates.
