News brief: Optimism reported the following development on November 10, 2026, 23:32 UTC.
What happened
Add two flags for tuning the proofs-history engine's persistence, both defaulting to current behavior: --proofs-history.persistence-threshold (default 5, 1 to 10000): blocks buffered before each persistence batch. Backpressure stays at twice the value.
Why it matters: what to verify
For network developments, distinguish an announcement from a deployed upgrade. Check rollout dates, affected users and any migration steps in official documentation.
What this means for airdrop research
This report is not confirmation of an airdrop, snapshot or claim. Verify any campaign separately through official project channels before connecting a wallet or paying fees.
