ChainCatcher report, according to CryptoSlate, Solana increased the block compute unit limit from 60 million to 100 million on July 29, a 66.7% increase. This adjustment provides more parallel processing capacity for unrelated transactions, reducing the block space occupied by a single popular account from 20% to 12%. However, the maximum compute units allowed to be written to the same account per block remains at 12 million CU, and the account data increment limit remains at 100 MB, meaning the congestion bottleneck for popular accounts has not been fundamentally resolved. If a large volume of transactions requires writing to the same popular account—such as a high-volume DEX or liquidation contract—they are still constrained by this limit. The official team has not provided actual comparative data on transaction confirmation rates, fees, block propagation, or replay performance before and after the upgrade.
Solana Increases Block Capacity by 66%, But Hot Account Bottlenecks Persist

Summary
On July 29, Solana increased its block compute unit limit to 100 million, a 66.7% rise from 60 million. On-chain data shows this change reduces a single hot account’s block usage from 20% to 12%. However, the limits of 12 million CUs and 100 MB per block per account remain unchanged, leaving bottlenecks unresolved. High-volume DEXs and liquidation contracts still face constraints. The official has not shared pre- and post-upgrade metrics on fees, confirmation rates, or block propagation. Solana’s move may influence which altcoins to watch in the coming weeks.
