[Solana Increases Block Capacity by 66%, But Traders Still Face Hot Account Bottlenecks] According to CryptoSlate, on July 29, Solana raised the block computation unit limit from 60 million to 100 million, an increase of 66.7%. This adjustment provides more parallel processing space for unrelated transactions, reducing the block usage rate of individual hot accounts from the previous 20% to 12%. However, the computation limit for writing to the same account per block remains at 12 million CU, and the account data increment limit remains at 100MB, meaning the congestion bottleneck for hot accounts has not been fundamentally resolved. If a large number of transactions need to write to the same hot account (such as high-volume DEXs or liquidation contracts), they are still constrained by this quota. The official report did not provide actual comparative data on transaction confirmation rates, fees, block propagation, or replay before and after the upgrade.
