Subject: Distinguish ZKsync blocks using "l1Batch" headers
X-Git-Url: https://git.ardis.lu/?a=commitdiff_plain;h=6a575747332be6a824264bc8ae09395266ca851b;p=block-hash-calculator

Distinguish ZKsync blocks using "l1Batch" headers

Based on a search, only ZKsync-based chains use this "l1Batch" terminology.
