Solana Increases Block Capacity by 20%, Eyes 100M CU Upgrade
2 Mins Read
The Solana network has increased its block capacity by 20%, raising the limit from 48 million to 60 million compute units (CU) per block, with proposals underway to raise that even higher by year’s end.
Higher Capacity Means Smoother Transactions
The capacity upgrade, confirmed Tuesday, means more transactions can now fit into each block. Mert Mumtaz, CEO of Helius — a Solana infrastructure provider — explained that this directly benefits users and developers:
“This means lower fees, more flexibility for devs, and better user experience,” Mumtaz posted on X.
Each Solana transaction consumes a number of compute units, depending on its complexity. By increasing the compute ceiling per block, Solana reduces congestion risks — a known issue during past memecoin surges, such as the January 2025 flood when Trump-related tokens clogged the network.
Proposal to Push to 100M Compute Units
Beyond the 60M CU cap, developers are aiming for a bigger leap. Lucas Bruder, CEO of Jito Labs, has submitted a GitHub proposal to increase the block limit to 100 million CUs.
Bruder wrote that the original block cap was designed to prevent validator overload. However, with today’s infrastructure, Solana’s mainnet is no longer bottlenecked by execution times. The new limit would unlock more throughput and scalability without harming validator performance.
“This proposal aims at a substantial increase… to provide additional capacity to the network,” Bruder noted.
SOL Price Gains Amid Institutional Accumulation
The network upgrade comes at a time of renewed bullish momentum for SOL. On Monday, the token surged 12% to over $202, before settling around $191, according to Nansen data.
This comes as several institutions — including DeFi Development Corp and Bit Mining — announce large Solana treasury allocations. Bit Mining, a Bitcoin-focused company, revealed plans to raise $300 million to build a Solana token reserve.
Solana isn’t alone in scaling up. Ethereum’s gas limit also increased this week, hitting nearly 45 million units, up from 36 million. It’s the largest adjustment since February 2025, signaling wider industry efforts to boost transaction capacity as on-chain activity grows.
