Solana is raising its per-block compute limit from 60 to 100 million Compute Units, a 66% increase that will go live within 24 hours at the start of Epoch 1009. This upgrade, under proposal SIMD-0286 authored by Lucas Bruder of Jito Labs, marks the second major increase in less than a week following SIMD-0256 which moved the cap from 50 to 60 million on July 23, 2025. The update only changes the Maximum Block Units limit, leaving Max Writable Account Units at 12 million and Max Vote Units at 36 million. Investors should monitor validator metrics closely in the 48 to 72 hours after activation, as the higher compute requirements could potentially impact validator performance and contribute to increased centralization pressure.
