A critical bug was detected in the Zeitgeist runtime. The goal of this proposal is to deploy a runtime containing a fix for that critical bug.
As the bug shouldn't be disclosed to the public as long as a vulnerable runtime is still active, the code of the fixed runtime is private. It will be published on the public Zeitgeist repository shortly after deployment of the runtime containing the fix for the vulnerability.

To verify the hash of the proposed runtime, execute the following commands:
```sh
git clone git@github.com:zeitgeistpm/zeitgeist-private.git
cd zeitgeist-private
git checkout v0.4.3
SRTOOL_TAG="1.66.1" srtool build --build-opts "\-\-features=parachain" --package zeitgeist-runtime --profile production --root --runtime-dir ./runtime/zeitgeist
```

Verify that the value of "BLAKE2_256" within the "Compressed" section matches the value of the parameter within the `parachainSystem.authorizeUpgrade` call that is proposed in this proposal.

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

- **Problem Statement:** Mismatch in key types between Aura and Statemint collators causing block production failure.
- **Significance:** Inability to produce blocks impacts network functionality and validation.
- **Proposed Solution:** Implement a temporary runtime fix enabling ed25519 in Aura for Statemint collators.
- **Expected Outcomes:** Restoration of block production, validation of collator signatures, and subsequent migration back to sr25519 keys.
