Right now governance could only control byte-fee component of Rococo <> Westend message fees (paid at Asset Hubs). This PR changes it a bit: 1) governance now allowed to control both fee components - byte fee and base fee; 2) base fee now includes cost of "default" delivery and confirmation transactions, in addition to `ExportMessage` instruction cost.
Assets Parachain
Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".
Asset Hub allows users to:
- Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
- Set admin roles to manage assets and asset classes.
- Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existance of accounts sans DOT/KSM.
- Pay transaction fees using sufficient assets.
- Transfer (and approve transfer) assets.
- Interact with the chain via its transactional API or XCM.
Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.
See the article on Asset Hub as common good parachain for a higher level description.
Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
