# InvalidVotingPowerEmaAlpha (/docs/errors/chain/InvalidVotingPowerEmaAlpha)

The alpha passed to set the voting power EMA exceeds 10^18, which represents 1.0. Check the `alpha` argument to sudo\_set\_voting\_power\_ema\_alpha; it must be at most 10^18, and the current value is in `VotingPowerEmaAlpha` per netuid.

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