Subnet Management - 4utr6 (Application)

This topic is intended to capture Subnet Management activities over time for the 4utr6 subnet, providing a place to ask questions and make observations about the management of this subnet.

This subnet was created to help support the growth of Caffeine AI

At the time of creating this topic the current subnet configuration is as follows:

Replace a node in subnet 4utr6

Motivation:
Replacing a dead node

Decentralization Nakamoto coefficient changes for subnet 4utr6-xo2fz-v7fsb-t3wsg-k7sfl-cj2ba-ghdnd-kcrfo-xavdb-ebean-mqe:

    node_provider: 5.00 -> 5.00    (+0%)
      data_center: 5.00 -> 5.00    (+0%)
data_center_owner: 5.00 -> 5.00    (+0%)
             area: 5.00 -> 5.00    (+0%)
          country: 4.00 -> 4.00    (+0%)

Mean Nakamoto comparison: 4.83 → 4.83 (+0%)

Overall replacement impact: equal decentralization across all features

The above subnet information is illustrated below, followed by a node reference table:

Map Description
  • Red marker represents a removed node (transparent center for overlap visibility)
  • Green marker represents an added node
  • Blue marker represents an unchanged node
  • Highlighted patches represent the country the above nodes sit within (red if the country is removed, green if added, otherwise grey)
  • Light grey markers with yellow borders are examples of unassigned nodes that would be viable candidates for joining the subnet according to formal decentralisation coefficients (so this proposal can be viewed in the context of alternative solutions that are not being used)

You may wish to follow the CO.DELTA known neuron if you found this analysis helpful.

CO.DELTA △

We’re a verifiably decentralised collective who review IC deltas (changes applied by NNS proposals). We follow a common code:

  • Look: We observe the details and context of NNS proposals
  • Test: We test and verify the claims made by those proposals
  • Automate: We automate as much as possible by building increasingly sophisticated tools that streamline and strengthen the reviewal process.

Every vote cast by CO.DELTA is the result of consensus among diligent, skilled and experienced team members acting independently. The CO.DELTA neuron follows the vote of D-QUORUM on NNS topics that the CO.DELTA team does not handle directly. You can therefore follow CO.DELTA on all topics and rely on the highest quality of vote.


Note that this analysis involved data provided by the IC-API, which is not open source. I’m in the process of switching over to more verifiable sources of this sort of information for future proposal reviews. See here for related discussion.

Proposal 137799 | Tim - CodeGov

Vote: Adopt

This proposal replaces node l4tph which appears in the dashboard as “Offline”. The replacement node appears in the dashboard as “Healthy”. As shown in the proposal, decentralisation parameters are unchanged and remain within the requirements of the target topology.

Proposal 137799 – LaCosta | CodeGov

Vote: ADOPT

The proposal replaces one dead node on subnet 4utr6:

  • Removed Nodes: nodes l4tph, Dashboard Status: Offline

  • Added Nodes: nodes awpkn, Dashboard Status: Healthy and Not assigned to a subnet

The decentralization remains unchanged across all features

The subnet is within the current approved IC Target Topology so no issues here.
