- Changes are in the release notes.  
- The upgrade needs voting by the Fellowship.  
- More details will come after the fix.

[Whitelisted Caller] DUPLICATE of 524

[Whitelisted Caller] Disable V2 descriptors node feature

- A vote (Ref#511) increased the number of validators to 700, which also allows more cores (140) to be used.  
- More cores mean more teams can buy them fairly in the next sale.  
- One team, Kreivo, lost its core and now has to make blocks manually, which is slow.  
- Instead of asking for a special core, this vote makes it fair for everyone to get one.

Rejected

Increase usable cores to 140

[Runtime 1.4.3] Upgrade Kusama Asset Hub

Kusama AssetHub has registered several assets with Polkadot Assethub as the owner. These assets include popular tokens like ETH, WETH, USDT, USDC, and many others. The goal is to support bridging ERC-20 tokens from Ethereum to Kusama in two steps: first from Ethereum to Polkadot, and then from Polkadot to Kusama using the P<>K bridge. A test demonstrating this process has been added to a GitHub repository.

Registers the following assets on Kusama AssetHub (with the asset owner being Polkadot Assethub &mdash;

The plan is to support bridging ERC-20s to Kusama by double bridging from Ethereum -&gt; Polkadot and then from Polkadot -&gt; Kusama in a second hop through the P&lt;&gt;K bridge. A test demonstrating this has been added here:&nbsp;

[Whitelisted Caller] - Register Snowbridge ERC-20 Assets on Kusama

Kusama Fellowship Referenda 97 is a proposal to increase the parachain validator set size from 600 to 700, keeping the maximum backing group size at 5. This change will increase the total number of usable cores to 140. The proposal also updates the setNDelayTranches from 257 to 299 to maintain the number of assignments per candidate at around 2.33. The justification for this parameter can be found in the ELVES paper and a discussion on the Polkadot SDK GitHub page.

This referenda increases the parachain validator set size from 600 to 700. The maximum backing group size is kept to 5, so the total number of usable cores increases to 140.
Additionally, also update the setNDelayTranches from 257 to 299, so that the number of assignments per candidate stays constant to around ~2.33, the justification why this is the desired value for this parameter can be found in ELVES <a href="https://eprint.iacr.org/2024/961">https://eprint.iacr.org/2024/961</a> paper and here.<a href="https://github.com/paritytech/polkadot-sdk/issues/6853#issuecomment-2540373492.">https://github.com/paritytech/polkadot-sdk/issues/6853#issuecomment-2540373492.</a>

[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.

A new upgrade of the relay chain to v1.4.1 is now up for vote: there was a bug found in the staking system which needs to be fixed &mdash; this fixes an issue related to staking in combination with nomination pools. This release pulls in changes directly from a custom Polkadot-SDK branch. The changes can be reviewed on <a href="https://github.com/polkadot-fellows/runtimes/releases/tag/v1.4.1">the release</a>.&nbsp;
The proposal is submitted on Whitelisted Caller track and Fellowship is voting on a whitelist.
Please review and vote at your convenience.&nbsp;

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.

This is a referendum to upgrade Kusama to <a href="https://github.com/polkadot-fellows/runtimes/releases/tag/v1.4.0">v1.4</a>. See the&nbsp;<a href="https://github.com/polkadot-fellows/runtimes/releases/tag/v1.4.0">fellowship release notes</a>&nbsp;for more details.
Of special note is enabling nomination pools participation in governance, removing funding to Kappa Sigma Mu Society, allowing burn parameters to be set via OpenGov, lowering parachains and data deposits on Kusama, adding all assets in pool with native xcm payment on Asset Hub, delegate stake pools in Kusama and improving bridges usage.
Enactment is set for block <a href="https://kusama.subscan.io/block/27155056">27155056</a> around 8am UTC on 19th Feb
Edited to fix an error and to add the enactment date.

[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.

Update Kusama v1.3.0

- The referendum increases the number of parachain validators from 400 to 500.
- It also increases the maximum backing group size from 4 to 5.
- The total number of usable cores stays at 100.
- Changing the backing group size helps reduce parachain block times.
- All 100 backing groups will still get rewards.
- The session lasts 1 hour, and group rotations happen every 1 minute.
- More details can be found in the provided links.

WHO: Kusama network

WHAT: Increase parachain validator set size from 400 to 500 and maximum backing group size from 4 to 5.

### 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.
