Solana News Today: Solana Increases Mainnet Block Limit to 60M Compute Units, Boosts Capacity

Solana has implemented a major upgrade to its blockchain network, raising the mainnet block limit to 60 million Compute Units (CU) following the activation of the SIMD-0256 proposal. This adjustment, effective July 15, 2025, aims to enhance the network’s capacity for transactions and smart contracts by aligning Compute Units—a resource metric—with increasing throughput demands [1]. The update is part of broader efforts to optimize scalability while maintaining security, with developers anticipating a potential expansion to 100 million CU by year-end, contingent on network performance and validator consensus [2].

The upgrade has drawn comparisons to Ethereum’s gas mechanism, with Compute Units serving a similar function in prioritizing transactions and managing computational resources. Wu Blockchain’s X account highlighted that the 60M CU threshold addresses growing congestion risks as decentralized applications (dApps) and on-chain activity expand [3]. Meanwhile, developers described the change as a long-anticipated step to meet rising demand for block space, reflecting confidence in the network’s capacity to adapt [4].

The adjustment underscores Solana’s balancing act between scalability and decentralization. While higher block limits could reduce transaction fees by increasing available capacity, critics caution that such changes might centralize processing power among larger validators with advanced hardware. Solana’s team has countered this by emphasizing safeguards, including dynamic fee adjustments and validator rewards tied to throughput efficiency. These measures aim to mitigate risks while ensuring network stability [1].

Binance noted that the roadmap for reaching 100 million CU includes intermediate steps, such as stress-testing the network at 60M CU to validate stability [2]. Developers are also working on tools to help users estimate transaction costs under the new framework, aiming to reduce uncertainty for both individual and enterprise users. The network’s performance will be closely monitored to determine whether the new limit achieves its goals without creating bottlenecks in other areas.

Analysts and developers remain cautiously optimistic. Wu Blockchain’s commentary framed the upgrade as a critical response to ecosystem growth, while Binance’s roadmap outlines conditional milestones for further increases [2][3]. The success of the upgrade will depend on how effectively Solana manages the interplay between block size, resource allocation, and validator participation.
