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). 
- Call hash for polkadot upgrade: `0x8eb2806cbdf1a4ba91334669b2476870134db3af5c77f418152af0ad354d3b32`
 
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. 

- Hash for XCM call (council motion) can be found [HERE](https://drive.google.com/file/d/1BvnGFDK2KVjvFNMxs6qA9evkeSyniOdS/view?usp=sharing).
 - Hash: `0x8adb4ccdf996f05fa7941ce3b56ecec6dd49a88d9db445963e813ac10cadd326`.
- Encoded call: `0x01028adb4ccdf996f05fa7941ce3b56ecec6dd49a88d9db445963e813ac10cadd326`
- Runtime release can be found [HERE](https://github.com/paritytech/cumulus/releases/tag/parachains-v7.0.0-rc8).

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!

Due to the scheduled auction failing to start, this referendum starts one.

Send a batch of dispatch calls.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.

- Polkadot and Statemint are going to be upgraded together.
- The Polkadot upgrade will improve block time degradation issues and make some changes to the runtime.
- The Statemint upgrade will include new features for creating and minting NFTs and allow HRMP channels to be used in both directions.
- The upgrade will address issues found by auditors and allow for the creation of fungible and non-fungible assets.
- The proposal will need to be voted on by the community before it can be enacted.
