<h3 id="summary"><strong>Summary</strong></h3>
<p>We propose to open a bi-directional channel between Moonbeam and Zeitgeist and to register Zeitgeist&rsquo;s native currency ZTG as xcZTG. Initially, the main use case will be to transfer ZTG between the two chains to create a trade pair in Stellarswap and offer it to any dApp on Moonbeam that wants to utilize it. Another potential use-case of the channel is to offer prediction markets and the Futarchy governance mechanism in the near future to Moonbeam and any dApp on Moonbeam. Further use cases shall be evaluated over the course of time.</p>

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

May be called from any origin except `None`.

- `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 the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

## Complexity
- O(C) where C is the number of calls to be batched.

- This proposal is about opening a channel between Moonbeam and Zeitgeist.
- They want to register Zeitgeist's currency, ZTG, as xcZTG on Moonbeam.
- The channel will be used to transfer ZTG between the two chains and for other purposes in the future.
- There is a technical process involved in accepting the channel request and registering xcZTG.
- They have calculated the transaction cost and have some specific details about the proposal.
