Block tag
enum
earliest: The lowest numbered block the client has available; finalized: The most recent crypto-economically secure block, cannot be re-orged outside of manual intervention driven by community coordination; safe: The most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions; latest: The most recent block in the canonical chain observed by the client, this block may be re-orged out of the canonical chain even under healthy/normal conditions; pending: A sample next block built by the client on top of latest and containing the set of transactions usually taken from local mempool. Before the merge transition is finalized, any call querying for finalized or safe block MUST be responded to with -39001: Unknown block error
Enum:
"earliest"
"finalized"
