According to Mumtaz, compute units on Solana function like fuel for a vehicle, as each transaction consumes a certain number of CUs depending on its complexity. For instance, a basic token transfer uses fewer CUs than a multi-swap operation across decentralized exchanges.
This upgrade is part of a broader effort to address execution constraints observed during periods of high network activity. Solana raised the CU limit to 50 million in June as a precautionary step to prevent disruptions.
Following the success of that implementation, developers moved forward with the second phase of lifting the cap to 60 million CUs.
Meanwhile, Mumtaz revealed that the team aims to eventually double the block capacity to 120 million CUs.
He explained that the increase would allow developers to build more expressive applications and reduce transaction fees, especially as demand grows.
When asked whether Solana’s block capacity might eventually become uncapped, Watt noted that core developers continue to debate the issue.
Watt added that static analysis or metering may become more useful if the network shifts toward asynchronous execution models.
