(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

The Big Picture
Registration fees can either be burned (deflationary) or recycled back as emissions. This controls which.
Use Cases
- Token economics tuning
- Deflationary vs recycling mechanics
From Chain Metadata
Set the behaviour of the "burn" UID(s) for a given subnet. If set to `Burn`, the miner emission sent to the burn UID(s) will be burned. If set to `Recycle`, the miner emission sent to the burn UID(s) will be recycled.
