Solana Upgrade Clears 100 Million Compute Units at Epoch 1009

Christian Barker (Barkmeta / Bark) and David Chaboki (Shibo) opened the Doginal Dogs Space by walking through the exact timing of the Solana change. SIMD-0286 is live on Solana mainnet as of Wednesday, July 29, 2026, at the start of epoch 1009. The Solana Foundation says the change raised the maximum block compute units from 60 million to 100 million, a 66 percent increase. The per-account writable cap stays 12 million CUs and the accounts data-size delta stays 100 MB. This is a live capacity gate, not Alpenglow and not a governance vote.

When a block limit rises and a hot-account cap does not, Bark (Christian Barker) and Shibo (David Chaboki) put 100 million CUs on the Doginal Dogs Space before they say the 12 million per-account cap is unchanged. Listeners heard the same parameters repeated so traders could map the upgrade to their own transaction loads. The feature gate listed on Solana.com carries the identifier P1BCUMpAC7V2GRBRiJCNUgpMyWZhoqt3LKo712ePqsz and was authored by Jito Labs engineer Lucas Bruder.

What the activation actually changes

The upgrade only widens the total work a single leader can schedule inside one block. Under the prior 60 million cap, 11.2 percent of blocks already reached 56 million CUs or higher. An 80 million intermediate step was reviewed and passed over. No developer or indexer changes are required, and the move sits apart from Transaction v1 4096, SGP-0001/0002/0003, SIMD-0550, SIMD-0437, and the separate Alpenglow release track.

What traders should watch next

Check the Solana.com upgrades page for the full parameter list and any follow-up posts from the Foundation. Run a few of your own high-compute transactions on mainnet to see whether confirmation times improve during busy periods. Track failed transaction rates on public dashboards rather than assuming lower fees will follow automatically. Compare current block utilization numbers against the old 60 million ceiling so any capacity gains become visible on the chart.

How the market is reacting so far

SOL traded near 96.34 dollars with a 0.9 percent gain on the day the upgrade activated, while BTC sat at 79,185.98 dollars and ETH at 2,484.01 dollars. The modest move suggests traders treated the change as routine maintenance rather than a narrative catalyst. Volume stayed in normal ranges across spot and perps, with no outsized positioning visible in the hours after epoch 1009 began.

Next steps for readers

Open the official Solana upgrades page and note the unchanged per-account limit before building new programs. Test a sample batch of transactions that previously hit the old ceiling. Watch block explorer data over the coming epochs to confirm the extra headroom actually reduces congestion. Keep an eye on any later posts from Jito Labs or the Foundation that outline follow-on tuning. The upgrade is already running, so the only remaining variable is how developers and traders choose to use the added room.
