Proposal 135539 Review | Lorimer - CO.DELTA △
VOTE: YES
TLDR: Replaces an offline node with an unassigned node.
This proposal does not change any of the formal IC Target Topology metrics in terms of their discrete values, however it does nudge the subnet closer to a situation where it would more easily violate them in the future (see ‘Subnet characteristic counts’ in the ‘Decentralisation Stats’ section below). In any case, this seems like a good proposal on the whole.
Country Discrepancies (4)
Minor discrepancies in terms of distance, and I think can be considered to be within a margin of error.
Decentralisation Stats
Subnet node distance stats (distance between any 2 nodes in the subnet) →
| Smallest Distance | Average Distance | Largest Distance | |
|---|---|---|---|
| EXISTING | 0 km | 7233.114 km | 19461.421 km |
| PROPOSED | 0 km | 7238.582 km (+0.1%) | 19461.421 km |
Subnet characteristic counts →
| Continents | Countries | Data Centers | Owners | Node Providers | Node Operator | |
|---|---|---|---|---|---|---|
| EXISTING | 6 | 28 | 39 | 37 | 37 | 40 |
| PROPOSED | 6 | 27 (-3.7%) | 39 | 38 (+2.6%) | 37 | 40 |
This proposal slightly reduces decentralisation in terms of jurisdiction diversity. 
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 | 18 | 3 | 2 | 2 | 3 | 1 |
| PROPOSED | 18 | 3 | 2 | 2 | 3 | 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)
-
Black dotted line connects to a small black marker that shows where the IP address indicates the node is located (according to
ipinfo.io). This is only displayed if it conflicts with where IC records indicate the node is located. See Country Discrepancies section above for more info.

You may wish to follow the CO.DELTA known neuron (coming soon) 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.
