Solana Validators Push SOL Burn and Disinflation Proposals to the Edge of the Vote Threshold

Two governance proposals that would alter Solana's supply curve from both ends are within reach of triggering a formal stake-weighted vote, but the signaling window closes August 18.

The bundled package known as SGP-0003 cleared Solana's initial governance support phase on August 4 and entered the discussion stage, per Decrypt. It pairs SIMD-0553, a resource-based fee proposal that would raise daily SOL burns by up to 14 times, with SIMD-0550, which would double Solana's annual disinflation rate. Validator support stood at 63 million SOL, or 14.4% of the network's staked supply. The formal vote threshold is 15%, equivalent to 65.16 million SOL, per Decrypt and CoinDesk. The gap is approximately 2.16 million SOL.

We run a Solana validator and are among those that have signaled support. Here is what each proposal actually changes.

SIMD-0553: Charging Transactions for the Resources They Reserve

Solana transaction fees today are nearly flat: a transaction that requests the maximum compute budget and uses only a fraction of it pays roughly the same base fee as one that uses exactly what it requested. The scheduler packs blocks against requested compute, so over-reservation holds space other transactions could have filled.

SIMD-0553 addresses this by introducing resource-based fees that charge transactions according to the network capacity they actually consume, burning those fees entirely rather than routing them to validators as rewards.

Anza, the core protocol development firm, estimated that at recent network activity levels, the change would lift daily burns from around 648 SOL (roughly $47,000) to between 7,500 and 9,000 SOL per day, or up to approximately $657,000. That is a 12-to-14-fold increase from the current baseline.

Even at the upper end of the projected range, daily burns would still fall well short of the network's daily SOL issuance of around 60,000 SOL, according to CoinDesk. The proposals would not make SOL net-deflationary. They would reduce net new supply entering circulation as activity-based burns scale with network usage.

SIMD-0550: Pulling the Inflation Floor Forward by Three Years

SIMD-0550 leaves Solana's inflation schedule intact at both ends: the starting rate and the terminal floor stay the same. What changes is the speed of the descent.

Solana's inflation began at 8% annually and falls by 15% of the remaining gap each year under the current schedule. The network's inflation rate today sits at approximately 3.8%, according to CoinDesk, and the 1.5% terminal floor is projected to arrive around 2032 at the existing pace. SIMD-0550 doubles the annual disinflation rate from 15% to 30%.

Under the accelerated schedule, the network would reach the 1.5% floor in the first half of 2029, three years ahead of the current timeline, per DeFi Development Corp's analysis. The faster descent removes approximately 18.9 million SOL from the emissions calendar (worth around $1.36 billion at recent prices, per the same release) over the compression window.

The tradeoff is direct: lower issuance means lower staking yield from block rewards. Validators and stakers would receive fewer newly minted SOL as the inflation rate falls faster. Whether that cost is acceptable depends on how each holder weighs near-term yield against reduced supply dilution. That is the question a stake-weighted governance vote is designed to surface.

How the Governance Vote Works: SGP-0003 at 14.4% of the 15% Threshold

As we covered when Solana's governance system launched last month, the Solana Governance Proposal framework uses stake-weighted signaling to determine whether a proposal advances to a formal vote. Validators who support a package signal on-chain with their staked SOL; the system measures total support as a share of the network's entire staked supply.

SGP-0003 requires 15% of staked supply (65.16 million SOL) for a formal vote to open. As of August 4, the package had cleared its initial support threshold and accumulated 63 million SOL in backing from over 70 validators, according to Decrypt. The remaining gap to the formal vote threshold is approximately 2.16 million SOL.

Support is concentrated. Helius hSOL$87.10+0.1% has been the single largest contributor, providing around two-thirds of the gathered stake, according to CoinDesk. Helius engineers also authored both proposals. Crossing the 15% threshold will require broader participation from validators who have not yet signaled.

The Validators and Institutions Backing SGP-0003

Named validators that have publicly signaled support include Jupiter JUP$0.188-2.4%, Staking Facilities, Drift Protocol DRIFT$0.012+1.7%, OtterSec, and Solana Compass, alongside Helius. Anatoly Yakovenko, co-founder of Solana Labs, publicly backed the proposals during the support phase.

The institutional backing extends to public markets. DeFi Development Corp. dfdvSOL$80.35+0.0%, the Nasdaq-listed company focused on accumulating and compounding SOL in its corporate treasury (ticker: DFDV), announced its support on August 4. CEO Joseph Onorati framed the proposals in terms of long-term network economics:

The proposals have also drawn backing from the protocol development layer. Anza CEO Brennan Watt issued concept support for both SIMD-0550 and SIMD-0553 earlier this year, placing them on a 2026 delivery track alongside SIMD-123.

What Needs to Happen Before August 18

The signaling window remains open until August 18. Validators can add their support at any point before that deadline; if 65.16 million SOL in backing accumulates before the window closes, a formal stake-weighted vote on both proposals opens.

The more telling question embedded in the current figures is what the support distribution reveals. Two-thirds of the gathered stake coming from a single validator (one that also authored the proposals) means the outcome depends on whether the broader validator community treats these as Helius proposals or as proposals for the network. The 70-plus validators who have already signed on represent a wider coalition than the initial snapshots suggested, but the gap to 15% is narrow enough that a handful of mid-sized validators could close it, or a similar group of holdouts could let the window expire without it crossing.

How the remaining two weeks unfold will answer that question.
