Invulernable Assignments for System Collators:
We've had some earlier discussions surrounding the assignment of invulnerable slots. A few solutions were tossed around, some of which involve off-chain voting. I'll like to take a stab at presenting a possible solution which I think can meet all needs, keep it all on-chain and be fair to all stakeholders.
From the discussions I've been exposed to, I see one need. It is that we need a tier of reliable collators who will not collude and are not susceptible to being permissionlessly replaced by bad actor(s). This tier is currently the invulnerables. There are however a few wants which differ in perspective from each stakeholder, they are to:
- Make the tier of invulnerables more fluid
- Reward good performers with some shielding from competitive permissionless slot battles
- Encourage an increased locking of tokens to secure slots
- Eliminate undesired behavior of taking a permissionless slot with a high bond and then re-entering with a lower bonded amou
