Key Takeaways
- The SIMD-0370 proposal aims to remove the fixed Solana compute unit block limit, currently set at 60-100 million Capacity Units (CUs).
- Validators could omit blocks they can’t process, creating natural incentives for hardware upgrades across the network.
- Critics are raising concerns that this will exacerbate centralization as operators with better-equipped infrastructure gain relative competitive advantages.

Solana’s Possible Migration to Dynamic Block Sizes
A novel proposal from Jump Crypto’s Firedancer team could drastically change Solana’s public network management of capacity. The SIMD-0370 proposal seeks to remove the “fixed Solana compute unit block limit,” arguing that the fixed block limits artificially limit the public network from truly being utilized. Rather than having a fixed limit, block producers can include as many transactions as their hardware can handle, while those validators who cannot process large blocks simply skip them using mechanisms that will be provided in the imminent Alpenglow upgrade.
The Performance Flywheel Effect
This change would establish what developers refer to as a “performance flywheel.” Block producers with faster hardware would be able to add more transactions to blocks while earning an incrementally higher fee. This would result in pressure on other validators to upgrade their hardware or risk losing rewards for missed blocks. The Solana compute unit block limit removal would effectively change the capacity of the network from a manually-adjusted parameter to a market-based feature that scales organically with validator capacity and network demand.

Solana Compute Unit Block Limit: Centralization Concerns and Technical Barriers
While the perceived benefits are notable, the SIMD-370 proposal has initiated productive discussion among Solana’s developer community. Anza’s and other organizations’ researchers have raised concerns about possible centralization, in which wealthy validators may control the block production.
Other technical issues might also pop up, like ensuring compatibility with future improvements, for example, multiple concurrent proposers and stability during rapid scaling. The Solana compute unit block limit has historically been serving as a stability mechanism, and removing it requires an assessment of these tradeoffs.
Summing Up
The SIMD-0370 proposal indicates a philosophical shift favoring market mechanisms and validator competition as opposed to centralized governance of network parameters. Combined with the Alpenglow upgrade, these types of improvements can improve operational tasks and even more adoption.
Furthermore, Jump Crypto, with Galaxy Digital and Multicoin Capital, formed Forward Industries, Inc., a Solana treasury firm, this month. The new venture secured $1.65 billion in private investment (cash and stablecoins) from the three firms.
Final Thought: If this proposal were successfully implemented, it could strengthen Solana’s position as the high-performance network it has become over the last few years. Soon, the community will need to manage the tension between pushing innovation and adhering to core principles of decentralization practices.
FAQs
What is a capacity or compute unit (CU)?
A compute unit refers to Solana’s measurement of computational work, similar to gas on Ethereum, used to meter transaction execution costs.
What is the Alpenglow upgrade?
Alpenglow is Solana’s upcoming consensus upgrade that reduces block finality from seconds to milliseconds and introduces skip-vote mechanisms.
What is a skip-vote?
It’s a mechanism where validators abstain from voting on blocks they cannot process in time, allowing the network to continue without them.
