Currently the manager account of Zeitgeist, the account that registered the parachain id 2092, has a some special privileges that were unlocked by the parachain (using governance) during the migration to provide the capability to recover after a failed migration. This includes setting the state and the state transition logic (runtime) for the Zeitgeist parachain as well as swapping leases (the privilege to be a parachain during a given timeframe). Currently the manager account can be targeted by attackers. In case of a successful attack, the attackers have complete control over the parachain.
This proposal aims to remove any privileges from the manager account of the Zeitgeist parachain by locking the chain, as the migration was successfully completed and emergency recovery is not required anymore.
Should the proposal pass, a call is executed that sends an XCM to Polkadot to execute the calldata 0x46062c080000, which translates to registrar.addLock(2092).
