Polkadot said on Twitter that motion No. 121 is now open for voting. The motion proposes to register the Shell Parachain on Polkadot to ensure block production, inclusion and final completion.
The functions of the Shell Parachain are extremely limited, and it does not even have the concept of an account. Shell only accepts messages from the relay chain to upgrade itself.
After the disputed code is activated, Shell can finally be upgraded to Statemint through another referendum. If the committee passes, the motion will go to a referendum.
