Jump Trading's Firedancer team has proposed removing Solana's fixed compute unit block limits, allowing validators to scale transaction capacity based on hardware performance. The SIMD-0370 proposal aims to incentivize validators to upgrade equipment, enhancing transaction processing capabilities. This follows the Alpenglow consensus upgrade, which introduced skip-vote mechanisms, rendering fixed block limits unnecessary. Critics express concerns over potential centralization, as larger operators with superior hardware could dominate the network. Additionally, the proposal raises compatibility issues with future protocol upgrades. In related developments, several Solana ETF proposals, including staking options, may receive US regulatory approval by mid-October, potentially increasing institutional interest in SOL tokens.
