Subnet Management - rtvil (Application)

Proposal 137914 Review | Lorimer :infinity: :dog_face: - CO.DELTA △

VOTE: YES

TLDR: Replaces a down node with an up node, while respecting the IC Target Topology. While there’s a reduction in the smallest distance between 2 nodes, on average the distance between nodes is increased by this proposal.

Decentralisation Stats

Subnet node distance stats (distance between any 2 nodes in the subnet) →

Smallest Distance Average Distance Largest Distance
EXISTING 20.707 km 9190.373 km 18499.629 km
PROPOSED 13.953 km (-32.6%) 9250.866 km (+0.7%) 18499.629 km

This proposal slightly increases decentralisation, considered purely in terms of geographic distance (and therefore there’s a slight theoretical increase in localised disaster resilience). :+1:

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.
