Collator selection methods and rewards have not changed since the launch of Statemine. This has been OK so far, with some community members running collators there, but the transaction fees are minuscule. With the release of XCM V3, we are planning a big technical push to put more functionality into…

[image] joepetrowski: In order to choose who gets to be a collator, we’ll need some parachain-friendly election mechanism. @kianenigma has mentioned having plans for something like this. A simple solution that we already have the infrastructure for is using approval stakes, so kind alike DPoS…

[image] kianenigma: Do we want to reward delegators as well? That’s an interesting question. I would actually say no - the main goal is to ensure that someone* has the incentive to produce blocks. The motivation for nominators in staking is to provide security, and having more DOT at stake (i…

We’d ideally make sure that whatever we do with staking on system parathreads does not mess up moving NPoS onto a system parathread, which primarily means: When the staking chain exports the tree for use in the election, who receives this tree?

Sure, but that seems like an implementation issue with moving staking into a parachain. How does that relate to this thread?

A couple small points first… [image] joepetrowski: See the discussion in this issue . @bkchr suggests that anyone can submit a valid block (removes set selection element too), but I’m not sure how this would handle many nodes trying to collate a block in the same slot? In general, parachains …

[image] rphmeier: since opportunity costs are less of a factor without a need for slashing, it seems to me that the rewards per system chain should be based on the real costs operational nodes for system chains undertake. This will vary heavily from one chain to the next - something like Statemi…

related: A Better Treasury System We definitely do need some way of evaluating validators’ performance so they can be paid accordingly. It seems like the system parachain itself is the best place to evaluate and reward that. Couldn’t the relay-chain treasury send to the system chain and have the s…

I guess a few questions / points of disucssion: What is the baseline level of hardware / performance needed for system / common good chains? Is it expected that they also meet the cpu/mem/disk performance of Standard Hardware that relay chain validators require? The recommendations for this affect…

A few of us ( @kianenigma @burdges @giulia @bkontur & Roman) discussed this topic and how to go about implementing something on a call today and wanted to sum up the discussion/first steps we plan to take. First, we generally agreed with @rphmeier ‘s point that different chains could have different …
