Solana's block capacity expands due to the recent SIMD proposal proposal.
In a significant move, Solana, the high-performance blockchain network, has increased its block capacity by 20%, raising the mainnet block limit from 50 million to 60 million Compute Units (CUs) through the SIMD-0256 upgrade, effective from July 15, 2025 [1][2][3]. This upgrade has the potential to benefit developers and users by allowing more transactions per block, thereby reducing congestion and potentially lowering fees.
The SIMD-0256 plan was initiated by the Anza engineering team, with Brennan Watt leading [1].
While the current 60 million CU limit is live and enhancing scalability, there's talk of a more substantial increase. Lucas Bruder, CEO of Jito Labs, has proposed a limit of 100 million CUs, aiming to double the current limit before the end of 2025 [1][3]. However, it's important to note that there is no official endorsement or implementation for this proposed limit yet—it remains a proposal under consideration, contingent on network performance and validator consensus [4].
Solana's market cap stands at $99.65 billion, holding 2.60% market dominance. The latest block adjustment is a result of active discussions on scalability.
Community discussions centre on balancing throughput with decentralization needs. Some critics voice concerns about elevated hardware requirements due to the block adjustment. Anatoly Yakovenko, Solana's co-founder, has remained silent on the rumoured 100 million CUs update.
As of July 24, 2025, Solana (SOL) trades at $185.17 with a circulating supply of 538.17 million.
This staged approach balances scalability improvements with network stability and decentralization considerations. The block limit was increased from 48 million to 60 million units, a step towards a potentially larger limit in the future. Stay tuned for updates on Solana's journey towards increased capacity and network growth.
