#### ethash\_submitHashrate

SubmitHashrate can be used for remote miners to submit their hash rate.\
This enables the node to report the combined hash rate of all miners\
which submit work through this node.

It accepts the miner hash rate and an identifier which must be unique\
between nodes.

**Params (2)**

Parameters must be given *by position*.

**1:**\
rate `hexutil.Uint64`

* Required: ✓ Yes
