Overview

• Jump Crypto’s Firedancer filed SIMD-0370 to scrap Solana’s roughly 60 million compute‑unit limit per block and enable dynamically sized blocks.
• The change is intended to follow the Alpenglow upgrade, which targets 100–150 millisecond finality and introduces skip‑vote functionality.
• Smaller validators could abstain from oversized blocks via skip votes, letting faster operators process more transactions.
• Supporters tout higher throughput and incentives to upgrade hardware, while critics warn of validator consolidation and skewed rewards.
• Developers are debating risks such as block propagation delays and potential security weakness if many validators skip, and no approval has been granted.
