# InvalidDifficulty (/docs/errors/chain/InvalidDifficulty)

The submitted proof-of-work hash does not meet the required difficulty (the faucet uses a fixed 1,000,000; PoW registration uses the subnet's difficulty). Check the `Difficulty` storage for the netuid and regenerate work against the current block.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).

## Remediation [#remediation]

Check the argument values against the operation schema

The same explanation is available in the terminal: `btcli explain InvalidDifficulty`.
