Solana developers are advancing a multi-year roadmap that aims to slash transaction finality to roughly 150 milliseconds and reshape the token’s supply dynamics. The Alpenglow consensus upgrade, now in testing and expected on mainnet by late 2025, is designed to cut finality from about 12.8 seconds and enable parallel processing and smart-contract-controlled transaction ordering. Two governance proposals could further alter SOL’s economics: SIMD-0550 would accelerate the annual reduction in new token issuance from 15% to 30%, keeping roughly 18.9 million SOL out of circulation, while SIMD-0553 would raise the daily token burn rate from about 648 SOL to between 7,500 and 9,000. Solana already leads in tokenized equity spot trading volume with over 96% of the market in June and more than 300,000 real-world asset holders, though Ethereum still holds a larger total tradeable tokenized asset value at $15.5 billion versus Solana’s $3.3 billion.
