Solana lifts block compute cap by 66.7%, but hot-account congestion remains

Solana raised its per-block compute unit ceiling from 60 million to 100 million on July 29, a 66.7% increase, according to Odaily. The change gives unrelated transactions more room to run in parallel and lowers the share of a block that a single hot account can consume to 12%, down from 20% before the adjustment. Even so, the upgrade did not change two limits tied to account-level contention: the per-block compute cap for writes to the same account remains 12 million CU, and the cap on account data growth remains 100 MB. That leaves a core bottleneck in place for workloads that need to write repeatedly to one heavily used account. Odaily said this could still constrain high-volume decentralized exchanges and liquidation contracts when many transactions compete for the same account in a block. The report also noted that Solana officials have not released before-and-after data on confirmation rates, fees, block propagation, or replay performance following the change.

Solana raises per-block compute cap to 100 million CU, but hot-account limits remain

Solana increased its per-block compute unit ceiling from 60 million to 100 million on July 29, a 66.7% jump, according to CryptoSlate. The change gives unrelated transactions more room to run in parallel and reduces the share of block space that a single hot account can consume, cutting that figure from 20% to 12%. The upgrade does not remove the main bottleneck tied to heavily used accounts. Solana still keeps the per-block write limit for the same account at 12 million CU, and the cap on account data growth remains 100 MB. That means transactions that need to write to one hot account at the same time can still run into the same constraint, even after the broader block-level compute ceiling was raised. CryptoSlate said this issue remains relevant for workloads such as high-volume decentralized exchanges and liquidation contracts, where many transactions may compete to touch the same account within a block. The report also noted that Solana officials have not published before-and-after operating data on transaction confirmation rates, fees, block propagation, or replay behavior following the adjustment.

Solana Developers Rush to Fix Network Congestion as 70% of Transactions Fail

Anza, a Solana-focused development collective, is tackling network congestion causing 70% transaction failure rate. Patches expected next week, with Agave client updates and QUIC protocol fixes underway.
