Adjusting Target Topology for Caffeine Scaling: 60 application subnets and a US subnet

Proposal 137339 Review | Lorimer :infinity: :dog_face: - CO.DELTA △

VOTE: NO

TLDR: The proposed subnet topology contains 2 nodes from the rbn2y+g7dkt+acqus cluster (more than 1 breaks the ‘independent party’ imperative that each subnet needs to adhere to). The nodes involved are:

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.
