Subnet Management - cv73p (Application)

[Lorimer]

Proposal 136577 Review | Lorimer - CO.DELTA △

VOTE: NO

TLDR: The proposal does not provide reference to sufficient evidence in order to verify/confirm its claim.

@Lorimer

This is a requirement that has been brought up as necessary time and again. I do not wish for proposals like this to continue being normalised. Nudging nodes in and out of subnets is an operation that carries significant security implications, and all the supporting evidence/justification for the swap should be provided in the proposal summary (it’s not something voters should be expected to have to hunt for).

Decentralisation Stats

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

	Smallest Distance	Average Distance	Largest Distance
EXISTING	475.773 km	6695.501 km	16654.257 km
PROPOSED	475.773 km	6502.709 km (-2.9%)	16654.257 km

This proposal slightly reduces decentralisation, considered purely in terms of geographic distance (and therefore there’s a slight theoretical reduction in localised disaster resilience).

Subnet characteristic counts →

	Continents	Countries	Data Centers	Owners	Node Providers	Node Operator
EXISTING	3	13	13	13	13	13
PROPOSED	3	13	13	13	13	13

Largest number of nodes with the same characteristic (e.g. continent, country, data center, etc.) →

	Continent	Country	Data Center	Owner	Node Provider	Node Operator
EXISTING	6	1	1	1	1	1
PROPOSED	6	1	1	1	1	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.
