Constants

const EmulatorInitCadenceHeight = uint64(0)

Default InitCadenceHeight for initializing the database on a local emulator. TODO: temporary fix until https://github.com/onflow/flow-go/issues/5481 is fixed upstream and released.

const LiveNetworkInitCadenceHeght = uint64(1)

Default InitCadenceHeight for initializing the database on a live network. We don't use 0 as it has a special meaning to represent latest block in the AN API context.
