Jump Crypto proposes removing Solana’s fixed block limit to let validators handle more based on their hardware;
The plan encourages node operators to upgrade systems or risk missing rewards by skipping high-demand blocks;
If accepted, the change could cut transaction finality to 150ms but may raise concerns about validator centralization.

Jump Crypto, the developer behind the Firedancer validator client, has proposed a change to how Solana SOL $206.63 handles its block computation limits.

The idea focuses on removing the network’s fixed compute unit cap, which currently restricts each block to 60 million units.

Anza, a research group formed from Solana Labs, shared in a post on X that this proposal, called SIMD-0370, could be introduced after the upcoming Alpenglow upgrade. According to Anza, this system would allow stronger validators with better hardware to process more demanding blocks.

In contrast, less powerful nodes would be able to skip those. This system encourages operators to upgrade their equipment and improve their software to stay competitive, as skipping blocks would mean missing out on potential rewards.

The concept aims to create a cycle where validators are pushed to improve performance to keep earning transaction fees. If adopted, the network could support faster and larger volumes of transactions without depending on a universal limit.

The upgrade is expected to bring faster transaction finality, which will reduce the time from roughly 12.8 seconds to just 150 milliseconds.

However, not everyone is convinced this is a safe path. Akhilesh Singhania, an engineer who commented on GitHub, stated that if only large validators can afford to keep upgrading, smaller participants might be pushed out.
