The Jump Crypto team, which is actively developing the high-performance Firedancer client for the Solana ecosystem, has announced a new initiative aimed at enhancing the network. According to proposal SIMD-0370, the company calls for the complete removal of the current fixed limit on computational units (CU) per block in Solana.

Goals of the Changes and Impact on Network Performance
The proposed innovation aims to significantly boost network performance. It is expected that lifting the strict block limits will encourage validators with outdated equipment to upgrade to modern technologies, positively impacting transaction processing speed. Following the implementation of the Alpenglow update, which has already received nearly unanimous support from the community and is set to launch in December 2025, the realization of this initiative will mark the next stage in the development of Solana.
The Alpenglow update, announced in May 2025, is positioned as the largest in the protocol’s history. It is expected to reduce transaction finalization time from 12.8 seconds to 150 milliseconds and significantly enhance the network’s resilience.
Potential Risks and Community Response
Currently, the Solana network has a limit of 60 million computational units per block. Removing this limit will allow each validator to process as many transactions as their equipment can handle. This move could lead to increased throughput; however, concerns about potential centralization have already emerged within the community.
“This creates a performance cycle: block producers pack more transactions to earn more fees. Validators who miss blocks lose rewards, so they upgrade their equipment and optimize their code. Better performance in the network means that producers can safely push the boundaries further.”
Earlier in May 2025, Jito Labs CEO Lukas Bruder proposed raising the limit to 100 million CU, but the current proposal suggests a complete removal of restrictions. Engineer Achiles Singhania expressed concern that increasing equipment demands could drive smaller validators out of the market, leaving only larger players.
Despite the controversial assessments, the Jump Crypto initiative is viewed in the broader context of strengthening Solana’s resilience and diversifying the validator network. Firedancer has been operating on the mainnet in test mode since September 2024, allowing for the evaluation of new solutions in real-world conditions.
