# InvalidSeal (/docs/errors/chain/InvalidSeal)

The seal hash recomputed from the supplied `block_number`, `nonce` and key does not equal the submitted `work`. Verify the PoW solver built the seal for the same key and block it submits, and that the work bytes were not corrupted in transit.

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