The bitgreen parachain was upgraded from a shell runtime to our latest runtime code at block 191202.

The upgrade executed without issues and the parachain continued to produce blocks. The upgraded parachain runtime introduced a couple of new pallets, the pallet-parachain-staking among them. This new pallet was responsible to assign new validators to session pallet and by extension the aura pallet. After the runtime upgrade, when a new session was triggered, it set the new authorities to an empty set since the pallet-parachain-staking was not set with any initial values.

We have explored all other solutions and after discussion and advice from Parity devs have created this proposal. Our humble request to the TC is to fastrack this proposal, this is purely a technical rollback since our chain has no user transactions or funds yet. We would like to distribute token rewards as soon as possible. Similar parachain resetshave been fastracked by the TC in the past and we request that our proposal be fastracked aswell.

Preimage is submitted. 



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.

- The bitgreen parachain was upgraded successfully.
- A new pallet called pallet-parachain-staking was added.
- There was an issue with the new pallet that caused a problem with assigning new validators.
- The team has created a proposal to fix the issue and is requesting it to be fast-tracked.
- The proposal hash is 0xfc0c33d0c0ae08d940fddadb11e239710da69b8660eaae7f77ea102a331e4ebe.
