This referenda increases the parachain validator set size from 400 to 500 and the maximum backing group size from 4 to 5. The total number of usable cores remains 100.

The reasons for also changing the backing group size are:

- https://kusama.polkassembly.io/referenda/294 changes to a backing group of less than 5 has shown to increase parachain block times
- keeping the same number of total cores such that all 100 backing groups get rewards given the session is 1 hour and group rotations happen every 1 minute

- **Problem Statement:** Increasing the parachain validator set size from 400 to 500 and the maximum backing group size from 4 to 5 to optimize parachain block times.
- **Significance:** Changing the backing group size has shown to improve parachain block times, ensuring all 100 backing groups receive rewards within a 1-hour session with group rotations every 1 minute.
- **Proposed Solution:** Increase the parachain validator set size and backing group size while maintaining 100 usable cores.
- **Expected Outcomes:** Enhanced efficiency in parachain block times and improved rewards distribution for all backing groups.
