Solana developers have proposed increasing the network's block capacity from 60 million to 100 million compute units (CUs), nearly doubling its transaction throughput just days after implementing a 20% capacity upgrade. The new GitHub proposal by Lucas Bruder, CEO of infrastructure firm Jito Labs, argues that Solana's current traffic "is largely not constrained by large block execution times," making the expansion feasible to ease congestion and accommodate future demand.
This follows Tuesday's upgrade that raised block capacity from 48 million to 60 million CUs. Mert Mumtaz, CEO of developer tooling provider Helius, confirmed the recent increase enables lower fees, improved user experience, and greater flexibility for developers during periods of high demand. Both upgrades address network strain experienced earlier this year when memecoin trading surges caused transaction failures.
Bruder emphasized that original block limits were designed to let validators keep pace, but infrastructure optimizations now allow larger blocks without performance degradation. Mumtaz separately noted the goal is to at least double the current 60M CU limit. The proposal comes amid growing institutional interest in SOL, with Nasdaq-listed DeFi Development Corp nearing 1 million SOL in treasury holdings and Bitcoin miner Bit Mining announcing a $300 million Solana-focused treasury initiative.
