Dear community,

This referendum seeks to adjust the invulnerable collator set of Polkadot Asset Hub.

The main objective is to make the invulnerable set better aligned with the risk profile and importance of the respective System Chain, while also keeping the assignment process efficient and consistent across the programme.

The curators also considered the historical assignment of slots across the System Chains. Where possible, the revised assignments favour operators with longer tenure and a demonstrated record of providing reliable service. At the same time, the changes are intended to help even the field for operators who have shown capability and interest in supporting additional System Chains.

Finally, this referendum adjusts the number of permissionless collator slots to ensure that permissionless collators do not outweigh the intended invulnerable set.

To support this, the curators applied a tiering model where each System Chain is categorised from Tier 1 to Tier 3, based on its perceived importance and risk profile. Under this model, Polkadot Asset Hub is categorised as a Tier-1 chain, with 8 funded community invulnerable collators.

For Polkadot Asset Hub, the proposed configuration is:

• Tier: Tier 1
• Community-funded invulnerable collators: 8
• Permissionless collator slots: 4

This referendum performs the following changes.
