[Runtime 1.4.2] Upgrade Asset Hub

- A new upgrade (v1.4.1) fixes a staking bug.  
- The bug affected staking with nomination pools.  
- Changes come from a special Polkadot-SDK branch.  
- You can check the changes on GitHub.  
- Voting is happening on the Whitelisted Caller track.  
- The Fellowship is deciding if it should be approved.  
- A post-mortem explains the bug in detail.

Kusama Runtime Upgrade to v1.4.1

Kusama is having a referendum to upgrade to version 1.4. This upgrade will let people in nomination pools join in making decisions, stop giving money to a group called Kappa Sigma Mu Society, and make some changes to how things work on Kusama. The upgrade will happen around 8am UTC on February 19th.

[Whitelisted Caller] Upgrade Kusama to v1.4.0

- The change increases `schedulerParams.lookahead` from 2 to 3.
- `scheduler.lookahead` shows which parachains will be scheduled soon.
- Currently, it shows info for only 2 blocks ahead.
- `asyncBackingParams.allowedAncestryLen` allows candidates to be built on 3 blocks.
- This creates a mismatch between the two values.
- Increasing `schedulerParams.lookahead` to 3 fixes this mismatch.
- It aligns the claim queue with async backing parameters.

[Whitelisted Caller] Update schedulerParams.lookahead configuration parameter to 3

- A decision was made to increase the number of parachain validators from 500 to 600.
- The maximum group size for backing stays at 5.
- This change allows for 120 usable cores.
- The setNDelayTranches was updated from 89 to 257.
- This update reduces assignments per candidate from about 5.61 to 2.33.
- The reasons for these changes are explained in a research paper and a GitHub discussion.

[Whitelisted Caller] Increase max_validators to 600

- Kusama Relay Chain and System Chains are updated to their latest versions.
- Kusama Asset Hub was not updated in v1.3.3, so other chains were delayed.
- Kusama Asset Hub and Encointer are updated to v1.3.4.
- Relay Chain, Kusama Bridge Hub, People Chain, and Coretime Chain are updated to v1.3.3.
- v1.3.4 fixes the issue with Kusama Asset Hub.
- v1.3.3 is the most recent version for the other chains.
- Both versions are part of the fellowship release.

[Whitelisted Caller] Upgrade Kusama to 1.3.4

### Fixing The Total Issuance

- A bug caused the Total Issuance (TI) to differ from the actual sum of all account balances on Kusama.
- The issue was fixed, but the TI still needs to be adjusted to match the actual balances.
- A script was used to measure the difference between the expected and actual TI.
- The difference is 56.331363194817 KSM, which needs to be subtracted from the TI.
- A whitelisted call will be made to adjust the TI using a specific function.
- This adjustment will be first tested on Kusama before being applied to Polkadot.
- The goal is to ensure the TI accurately reflects the total amount of existing tokens.

WHO: The author of the proposal.
WHAT: Proposes a whitelisted call to re-align the Total Issuance tracking with the actual Issuance on Kusama and Polkadot.
PRICE/TIMEFRAME/RESOURCES: Not specified.

### Kreivo Parachain Incident Summary

- **Date**: June 29
- **Issue**: Kreivo stopped producing blocks after a runtime upgrade to version 0.13.0.
- **Causes**: The upgrade introduced new features and updated the PolkadotSDK from 1.5 to 1.12, but missed crucial intermediate migrations.
- **Impact**: 
  - Virto team's salaries are affected as they are paid through the DAO's governance.
  - KSM Community cannot vote on OpenGov proposals.
- **Solution**: An updated WASM runtime will fix the issue, allowing a manual code upgrade.
- **Request**: Kusama governance and the Fellowship are asked to approve unlocking the parachain.
- **Future Plans**: A public postmortem will be conducted, and additional safeguards will be implemented.

WHO: Kreivo team, Kusama governance, and the Fellowship.

WHAT: Requesting approval to unlock the Kreivo parachain to restore functionality by preparing an updated WASM of the runtime that fixes the issue.

PRICE/TIMEFRAME/RESOURCES: Not specified.

Update Kusama System v1.2.4

Assign core for People Chain directly on relay

- This referendum helps make the network bigger by allowing up to 500 validators.
- It changes how validators vote to make the process faster and use less computer power.
- Validators will use a new way to vote and can approve multiple things at once with one signature.
- These changes help reduce the amount of data and work the network needs to do.
- The goal is to make the network handle more validators smoothly.
- The changes were made in late 2023.
- You can learn more about these updates on GitHub.

WHO: Polkadot network validators

WHAT: Enact two approval voting protocol improvements to scale up the number of parachain validators to 500.

Enable Identity Again on People Chain

Upgrade Kusama Relay Chain for People Launch

Register People Chain and upgrade Coretime Chain to v1.2.3

- Kusama needs an upgrade to fix issues with core sales and bridges.
- The upgrade will fix a problem where a message about leases didn't work because of a weight mismatch.
- The upgrade will also let parachains renew their cores if they had leases before core sales started.
- After the upgrade, core sales will restart 7 days later.
- There's a bug in the Kusama BridgeHub that can cause problems with validator set changes.
- This bug has already caused issues on the Polkadot BridgeHub, stopping traffic from Kusama to Polkadot.
- The upgrade will fix this bug on Kusama BridgeHub.
- The proposal is being voted on to make sure it can go through.

The proposal suggests upgrading Kusama to the latest release (1.2.2) to fix issues with core sales and bridges. The upgrade will include a fix to ensure every parachain can renew their core and reset the sales state. The upgrade will also fix a bug in the Polkadot-GRANDPA-light-client running on Kusama BridgeHub. The proposal is submitted on the Whitelisted Caller track, and a parallel submission is up for a vote on Fellowship to whitelist the proposal.

### Kusama Async-Backing Referendum

- **Purpose**: Enable faster block production for parachains.
- **Current Status**: Async-backing logic is active but in sync mode, producing blocks every 12 seconds.
- **Proposed Change**: Parachains can choose to produce blocks every 6 seconds.
- **Testing**: Successfully tested on Rococo and Westend since late 2023.
- **Dependencies**: Requires the upcoming `v1.2` runtime release.
- **Known Issues**: Some validators need to upgrade to avoid backing issues.
- **Action Required**: Validators should ensure their network keys are persistent to avoid discovery issues.

The proposal enables async backing on Kusama, allowing parachains to produce blocks at a faster rate of 6s. This is not mandatory, and they can still run at 12s. No critical issues are known, and the proposal won't change anything regarding that. The referendum will be enacted after the upcoming v1.2 runtime release.
