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 sees 10%-23% of hourly blocks exceed former compute cap after limit increase

Solana has started producing a notable share of blocks above its former compute ceiling after raising the per-block compute unit, or CU, limit from 60 million to 100 million. According to the Techub News digest, roughly 10% to 23% of blocks in any given hour have moved past the old 60 million CU threshold since the change took effect. The update points to immediate usage of the extra compute capacity now available on the network. Solana is described as a high-performance Layer1 blockchain known for high throughput and low transaction costs. CU serves as the base unit for measuring computational cost on the network. Citing Cointelegraph, the report said the higher block compute limit helps Solana process more complex transactions and smart contracts.

Solana launches 100M CU blocks on mainnet after raising block limit

Solana said its mainnet is now running 100M CU blocks, marking the rollout of a higher block compute cap under SIMD-0286. The proposal raised the per-block compute unit limit from 60M to 100M, a 66% increase in capacity. According to the team, roughly 1/9 of blocks over the past year ran close to full capacity during periods of elevated on-chain activity, and the new 100M CU ceiling is intended to give the network more room during those peak moments. Solana described the change as an initial step rather than the end of its scaling work. The network said additional upgrades are still ahead, including Alpenglow and a move toward 200ms slot times. The update points to a broader effort to expand throughput on mainnet while addressing usage spikes that have pushed blocks near their operational limits.

Solana to raise per-block compute limit to 100 million as SIMD-0286 nears activation

Solana’s mainnet is set to lift the compute cap for each block by 66% in less than 24 hours, raising the limit from 60 million compute units to 100 million. The change is part of SIMD-0286 and is scheduled to activate automatically at the start of Epoch 1009. According to the information cited by BlockBeats, the proposal was put forward by Jito Labs and keeps all other limits unchanged while expanding the room available for non-vote transactions. The stated goal is to let Solana’s roughly 400 millisecond blocks carry more and more complex transactions, which in turn is intended to improve throughput and reduce congestion-related failure rates and fee pressure. The move marks another capacity increase for the network following SIMD-0256, which had previously lifted the per-block compute ceiling from around 50 million to 60 million.
