Changes
UnsafePivotUpdator
which is working similar as generalPivotUpdator
except using head block hash (minus 64 blocks) instead of finalized block hash.In
PivotUpdator
we are using finalized block hash, because it can't be reorganized so is a safe starting point. Optimism is not providing finalized block hash until fully synced, so we need to use unsafe head block hash, which potentially can be reorganized and break the node. For more safety we are using head block minus 64. On Optimism reorganizations aren't common, so it can be a justified risk to significantly improve UX in most casesTypes of changes
