Solana's annual supply inflation could decline to about 1.1% by 2031 if SIMD-0550 and SIMD-0553 are approved in the network's August 18 governance vote, Grayscale Research said in an analysis by Zach Pandl, the firm's Head of Research. The modeled outcome, which assumes immediate implementation, steady network activity and a roughly unchanged staking (locking tokens to secure the network for rewards) ratio, would place SOL below gold's 1.8% annual supply growth and below the 3.3% average annual rise in U.S. consumer prices over the past decade, while Grayscale estimates Ethereum could reach about 0.4% annual supply growth by 2031 under EIP-8363, in line with Bitcoin's post-halving trajectory. SIMD-0550 would double Solana's disinflation rate to 30% and bring its 1.5% terminal inflation target forward from 2032 to about H1 2029, while SIMD-0553 would recast transaction fees to create a larger token burn (permanent removal from circulation), lifting daily SOL burns from about 648 to 7,500-9,000 under sustained activity. Grayscale said the changes would reduce staking yields, require a two-thirds supermajority of participating staked SOL to pass, and appear more likely to be implemented than Ethereum's proposal because they are further advanced in Solana's on-chain governance (blockchain-based voting) process.
