- Solana’s block limit increased to 60M CUs.
- Network congestion is expected to reduce.
- More demanding applications can now be developed on Solana.
Solana has officially raised its mainnet block limit to 60 million Compute Units (CU) as of July 15, 2025, following the activation of the SIMD-0256 proposal. The upgrade aims to enhance network capacity and alleviate congestion.
This action by Solana aims to facilitate higher throughput, directly impacting its native token, SOL, and enhancing its network appeal.
Main Upgrade Efforts
A collaborative effort led by the Solana Foundation, Solana Labs, and the developer community resulted in the block limit increase. Key figures such as Mert Mumtaz of Helius Labs emphasized the importance of expanded compute resources for developers.
“Each Solana transaction consumes a specific number of compute units depending on its complexity, and higher block limits give developers more headroom to build and run demanding applications without hitting constraints.” – Mert Mumtaz, CEO, Helius Labs Source
The increase is expected to have immediate effects on Solana’s DeFi, gaming, and NFT sectors. It provides more block space, potentially reducing transaction fees and attracting greater on-chain activity.
Market Implications
Market implications include possible shifts in developer preference toward Solana and away from competitors like Ethereum. Higher block limits may increase liquidity preference for Solana, influencing its market positioning.
Historically, such upgrades on Solana have spurred on-chain activity and dApp launches. There are potential outcomes like improved scalability and reduced costs, essential for the ecosystem’s growth. The Foundation plans to monitor network health before aiming for the 100M target by year-end.
