Please note this is a `batch` call proposal, combining the Polkadot upgrade with the Statemint upgrade: 

- Batch call hash: `0xbf60cbdd406036e0b6a3028763bfe20d9569780c0ffddc75cf209358fce3111c`
- Call design: [here](https://drive.google.com/file/d/1emtVtvZ-4skQnKDJj5r0_fP1bm-q4l4l/view?usp=sharing).

The **Polkadot runtime** will be upgraded to **v9170** - Release notes, runtime changes and proposal hash can be found [HERE](https://github.com/paritytech/polkadot/releases/tag/v0.9.17-rc4). This release improves the block time degradation issues, as seen [on Kusama](https://github.com/paritytech/polkadot/issues/4911). It also includes new changes in the runtime: like optimised weights and contains the PR to fully enable the bags list on polkadot, which **removes the need of having a strict maximum count for nominators** and also fully alleviates the phantom nominator issue. Both of these are explained further [in the January issue of "Polkadot Staking Progress”](https://docs.google.com/document/d/12MPnxGzoiRcJJYAGOYVU8dGUkqybuhoQX7wg5ouGfgU/edit?usp=sharing).

The **Statemint runtime** will be upgraded to [v700](https://github.com/paritytech/cumulus/releases/tag/parachains-v7.0.0-rc8):

-  The Uniques pallet includes an [extra storage item](https://github.com/paritytech/substrate/pull/9940) linking class owners to their NFT classes. This storage map comes in handy for UI developers, especially around the UX of creating and minting NFTs.

- With the inclusion of [Polkadot 4470](https://github.com/paritytech/polkadot/pull/4470) and [Cumulus 831](https://github.com/paritytech/cumulus/pull/831), parachains that have HRMP channels with Statemint will finally be able to use them in both directions. For parachain developers, note that this is a breaking change and if you've used reserve backed transfers from Statemint then you will need to migrate some storage items.

- It addresses all issues found by independent auditors regarding the Statemint runtimes. For Statemint, this means that once teleportation is ready (pending some final disputes related features) it should be OK to lift the call filter restricting asset/unique creation, opening the door for fungible and non-fungible assets in the Polkadot network. 

As usual, the Statemint proposal will dispatch an `authorizeUpgrade` message. All info about the upgrade can be found on the link above.

Feel free to use srtool yourself to check the proposal hash. If passed by the Council, this proposal should be voted by the community and enacted after. Make sure to vote at your convenience!

Schedule the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal. Increased to
  `FastTrackVotingPeriod` if too low.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

Weight: `O(1)`

- Polkadot and Statemint runtimes are being upgraded.
- Polkadot upgrade improves block time degradation issues and removes the need for a strict maximum count for nominators.
- Statemint upgrade includes improvements for UI developers and allows HRMP channels to be used in both directions.
- Statemint upgrade addresses all issues found by auditors and opens the door for fungible and non-fungible assets in the Polkadot network.
- The upgrades will be voted on by the community and enacted if passed.
