### Phala Network Parachain Issue

- Phala Network (ID: 2035) recently became a parachain.
- The team discovered a misconfiguration in the genesis runtime.
- Both sudo and democracy are disabled, preventing runtime upgrades.
- Without relaychain assistance, the parachain will be "bricked."
- The team proposed a `Paras.forceSetCurrentCode` call to fix this.
- Proposal hash: `0x7af427aa7665a073ca61b83c04791f185d9170ea2e49a8a7be323650cea8b75f`
- More details are available in the discussion link: [Polkassembly Post](https://polkadot.polkassembly.io/post/1005).

Runtime Upgrade v9180 - Polkadot Network

- **Composable Finance** faced a similar issue on Kusama as on Picasso chain.
- The problem was due to a stray `todo!` in weight calculations for pallet-democracy.
- This error would have caused the chain to stop working after a certain period.
- A public wasm file to fix the issue is available [here](https://github.com/ComposableFi/composable/releases/tag/v2.1.2).
- The preimage design is shown in the image linked in the original post.
- The preimage hash is `0xad2813b46b52fe8f38cb5af7da9c7f0f66416900070b949daa62cf92bbdc6fd7`.
- The preimage has already been submitted.

Help Composable Finance Unbrick Their Chain

- This proposal suggests changes to Polkadot's nomination limits.
- It aims to increase the number of possible nomination intentions from 22,500 to 50,000.
- The proposal also suggests lowering the stake required to submit a nomination intention from 10 DOT to 1 DOT.
- These changes are meant to prevent the "nominate" transaction from becoming unavailable.
- The proposal should be enacted before the number of nominators reaches 22,500.
- It is designed to relax limits without negatively affecting stakers.
- The proposal is explained by Kian from the Staking team.

Polkadot Runtime Upgrade to v9170 and Statemint Runtime Upgrade to v700

### Summary of the Proposal

- The proposal aims to temporarily increase the nomination limit to 160 DOTs, similar to [motion 157](https://polkadot.polkassembly.io/motion/157).
- This change allows the `chill_other` transaction to be used, helping to manage the number of nominators.
- The previous proposal had a major flaw: it used PLANKs instead of DOTs, the smallest unit of the DOT currency.
- The correct value for the minimum nominator bond should be `1600,000,000,000` PLANKs.
- The call data and hash for the correct proposal are provided.
- This change is necessary to keep the nomination ecosystem active while waiting for the next runtime upgrade.

Polkadot’s Update to 160 DOTs as minimum nomination limit: A follow-up proposal fixing a unit mistake

- Polkadot planned to remove the 120 DOTs nomination limit with the 0.9.16 upgrade.
- The 0.9.16 upgrade was delayed on Polkadot due to issues on Kusama.
- The number of nominators in Polkadot reached the 22,500 limit.
- A temporary increase to 160 DOTs is proposed to manage the nomination limit.
- This change allows the `chill_other` transaction to reduce the number of nominators.
- The proposal aims to keep the nomination ecosystem active while waiting for the 0.9.16 upgrade.
- The call hash and call data for the proposal are provided.
- The preimage for the proposal has been submitted.

Runtime v9150 on Polkadot Network

- Shell upgraded Statemint to use new keys, but there was a key type mismatch.
- Aura uses sr25519 keys, but Statemint's keys were ed25519.
- A temporary fix was made by creating a new runtime to allow ed25519 keys in Aura.
- This fix will let validators check collator signatures.
- Once blocks are produced, Aura will switch back to sr25519 keys.
- The call hash for this change is `0x0e21b5233c7591ee89eca0cae71cf9a9a4c45fe2393075ab33361a673f5d322d`.
- The preimage for this change is shown in the image link.

Fix Statemint - Aura Key Scheme

- This is a follow-up to Referendum 46, which failed due to no default XCM version set in Polkadot.
- A protection was added to prevent the Relay Chain from sending messages without a safe version, after a previous vulnerability.
- This is the first cross-chain interaction for Polkadot, so the version was not initialized.
- The new batch includes the same two calls as Referendum 46, plus an additional call to set the default XCM version to 2.
- The images show the details of the calls and the XCM version setting.

Upgrade Shell to Statemint (with XCM Fix)

### Summary of Scheduled Transactions

1. **Two Transactions**: Two transactions are scheduled to ensure `set_storage` happens before the upgrade authorization.
2. **Set Storage**: The first transaction sets storage keys in Shell for Statemint's "genesis".
   - Includes setting Aura collators and `SafeXcmVersion` to `2`.
3. **Authorize Upgrade**: The second transaction authorizes the upgrade to Statemint.
   - Once authorized, the runtime can be submitted for upgrade.
4. **Shell Constructions**: Both transactions are constructed on Shell and dispatched via XCM from the Relay Chain.
5. **Polkadot Proposal**: The proposal schedules these messages to dispatch from Polkadot to Shell, ensuring they are processed separately.
6. **Call Hash**: The call hash for the proposal is `0xa6830793b6a3473f66fbd7305a9e330dd2dd688df0e8fcbd0c9ff08d28040a34`.
