Altair Collator Onboarding Guide

Engineering Collator Introduction AIR
1

Congratulations to those selected to the first set of collators! Below is a collator onboarding guide that explains prerequisite steps for new collators and governance actions that the council will need to make, at this stage the minimum self bond will be 100,000 AIR. Ensure that funds for the self bond are unlocked and transferrable.

Steps

  • [ Prerequisite - Collator ] Please paste your collator name and account ID below as a reply to this post, and set the onchain identity of your account to your collator name and include contact details

  • [ Prerequisite - Collator ] Sync collator with both Kusama & Altair networks (push to telemetry so can be verified)

  • [ Prerequisite - Collator ] Collator to Register Aura Session Key:

    3326Ă—772 259 KB

    Important that the collator keystore is populated with the Aura key accordingly

  • [ Council ] Create preimage with Collator Allowlist. Using batch to do all at once:

    1354Ă—1618 258 KB

    Gather the preimage displayed at the bottom or from the event once the action is executed.

  • [ Council ] Now it is time to initiate the council flow to promote the proposal to a public referenda. There are two steps:

    • Create Council Motion with the following external majority proposal, use the preimage here
      2128Ă—792 142 KB
    • Once voting passed, the external proposal should appear in the democracy page
    • Now we open the “fastrack” (minimum is 900 blocks, 3h):
      2112Ă—1034 209 KB
    • Once voting passes, the proposal should be in the public referenda, ready to be voted by the community. Its important that at least 1 Aye vote is in for it to go through, if there are no votes, then it will default to Nay.

  • [ Collator ] At this point each collator can submit on their own their candidacy, by using the same account the used to register their session key in the first step. Logic will load the correspondant session key as a allowed collator in addition to a bonding fee (Council will set new bond fee)

    3354Ă—658 170 KB

  • Next session the new collator set will be assembled

Hello @Ash, thanks for the update! I have two questions regarding the collator setup

  1. I have 100,000 AIR but most of them are vested, I supposed it’s ok to set them as an initial bond?
  2. Is there already any official collator guide for Altair or do we have to figure out correct node setup ourselves?

Thanks :slight_smile:

Hey :slight_smile: yes vested funds should be able to be used for the bond and @ImdioR has posted the technical guide above!

@ImdioR Thanks, that was really useful for the entire collator community :slight_smile:

Hey All…

Good KarMa is almost ready. We just need to procure the AIR to self bond to our collator. Working on that part now (it’s been tough since we’re based in the USA and AIR isn’t easy to come by for us Yankees :smile:)

:white_check_mark: Onchain identity set with contact details.

  • Collator Name: Good KarMa
  • Account ID: kAHcdUYjKwuXxVXuppCgqypRdjTu25vybaxkeRHaje9GmPy3g

:white_check_mark: Collator synced with both Altair parachain and Kusama relay chain and pushed to telemetry.

:question: I think we set the session key correctly. I presume this entails rotating the keys on our collator node and using the generated key as the session key? Please correct me if we’re wrong.

:o: Self-bond collator with 100,000 AIR. Happening soon…

Cheers!

Good day TheMarcus
We have reached the penultimate active step:

[ Collator ] At this point each collator can submit on their own their candidacy, by using the same account the used to register their session key in the first step. Logic will load the correspondant session key as a allowed collator in addition to a bonding fee (Council will set new bond fee)

Collators should register candidacy and lock the bond.
