Proposal 135664 Review | aligatorr - CO.DELTA △

VOTE: YES

TLDR : Replaces 3 healthy nodes and makes decentralization slightly worse. For the sake of provider collusion agenda, I will vote to adopt.

  • 4 Nakamoto parameters city: Seoul,dc_id: zh2,owner: Everyware,node_provider_id: bvcsg-3od6r-jnydw-eysln-aql7w-td5zn-ay5m6-sibd2-jzojt-anwag-mqe above max identical count!!! :warning:

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.

It’s all the Frank Family.

Kontrapunt (Johan Frank) - 6 nodes, 4 critical subnets
Karel Frank (and Joey Frank) - 18 nodes, 2 critical subnets
Illusions in Art (Susan Frank) - 6 nodes, 1 critical subnet
Honeycomb Capital - 12 nodes,. 3 critical subnets.

Total between them = 42.

Hey @borovan have you come across the forum usernames form any of these node providers? Will you please tag them so they can respond?

It looks a group like this would qualify as a relationship cluster as proposed by DFINITY here, which could be used in the DRE tooling when deciding how to allocate nodes to subnets. I would really like to see that kind of idea materialize so we can more formally identify these kinds of relationships in acceptable ways. There is nothing that currently prohibits families or business associates from owning and operating nodes under different names, but there is a lot of utility in making sure the relationships are known and accounted for in the DRE tooling. It would help CodeGov and other reviewers a lot if we had a place to go to see these relationships so we can account for them in our reviews. Do you have a plan or suggestion for how node providers can announce their relationships or how the community can easily see these relationships?

Replace nodes in subnet tdb26

Motivation:

Calculated potential impact on subnet decentralization if replacing:

  • 1 additional node would result in: equal decentralization across all features
  • 2 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.3808
  • 3 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3808 to 3.4247
  • 4 additional nodes would result in: equal decentralization across all features
  • 5 additional nodes would result in: equal decentralization across all features
  • 6 additional nodes would result in: equal decentralization across all features

Based on the calculated potential impact, replacing 3 additional nodes to improve optimization

Note: the heuristic for node replacement relies not only on the Nakamoto coefficient but also on other factors that iteratively optimize network topology.
Due to this, Nakamoto coefficients may not directly increase in every node replacement proposal.
Code for comparing decentralization of two candidate subnet topologies is at:
dre/rs/decentralization/src/nakamoto/mod.rs at 79066127f58c852eaf4adda11610e815a426878c · dfinity/dre · GitHub

Note: the information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Here is an explaination of how decentralization is currently calculated,
and there are also instructions for performing what-if analysis if you are wondering if another node would have improved decentralization more.

Decentralization Nakamoto coefficient changes for subnet tdb26-jop6k-aogll-7ltgs-eruif-6kk7m-qpktf-gdiqx-mxtrf-vb5e6-eqe:

  node_provider: 12.00 -> 12.00    (+0%)
    data_center: 13.00 -> 13.00    (+0%)
data_center_owner: 13.00 -> 13.00    (+0%)
             area: 8.00 -> 9.00   (+12%)
          country: 5.00 -> 6.00   (+20%)

Mean Nakamoto comparison: 10.83 → 11.17 (+3%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.4247

Impact on business rules penalties: 10 → 0

Proposal 136733 Review | aligatorr - CO.DELTA △

VOTE: YES

TLDR: Replace nodes that hasn’t been performing well. Concern is IsleOfMan1 vc3nr node which is offline, but due to an incentive to kickstart using data center I’ve decided to adopt. Recent addition from IsleOfMan2 (which is dc in similar location) has been performing better and better xoefx. Decentralization will slightly improve too.

Proposal 136733 Review | Lorimer - CO.DELTA △

VOTE: NO

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

For more information about why there’s reasonable cause to consider these node providers clustered see here. Related discussion is also in a Transparent Node Providers thread.

Note that the proposal mentions →

Business rules check results before the membership change:

  • Node provider cluster 1 (6sq7t, vegae, eatbv) has 2 nodes in the subnet

This refers to the George Bassadone, GeoNodes, Geeta, Tina cluster. By proposing to move txh2c out of the subnet it attempts to resolve this issue, but it proposes to do so by introducing a new clustering problem.

More importantly, one of the nodes that it proposes to swap into this subnet is down (offline), while all 3 nodes it’s trying to take out of the subnet are up (online).

Country Discrepancies (2)

Both discrepancies are within fairly reasonable error tolerances in terms of distance.

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.

As a side note, this proposal leads to worse decentralisation in terms of clustering within Europe, which can be seen visually on the map above. Continent isn’t a formal part of the IC Target Topology, but it probably should be. See Decentralisation Stats above for the effect on subnet limits.

Proposal 136733 | Tim - CodeGov

Vote: Reject

This proposal replaces 3 nodes in subnet tdb26, appearing in the decentralization tool as “UP”, for an apparent reason of separating nodes in an identified cluster (although a “motivation” does not appear at the start of the proposal), but one of the replacement nodes vc3nr appears in the dashboard as “Status: Offline”. As shown in the proposal, decentralisation parameters would be improved with respect to country but would be outside the requirements of the target topology as there is a data centre and a data centre owner that each have more than one node in this subnet.

Proposal 136733 – LaCosta | CodeGov

Vote: REJECT

The proposal replaces 3 nodes on subnet tdb26:

  • Removes nodes txh2c Dashboard Status: Active, wazkf Dashboard Status: Active and vysyd Dashboard Status: Active.

  • Adds nodes vc3nr Dashboard Status: Offline, xll74 Dashboard Status: Awaiting and txayu Dashboard Status: Awaiting.

The motivation of the proposal is not only to improve the Nakamoto Coefficient across all features which it does, but to also remove node txh2c since it’s NP is flagged as being part of a cluster.

Unfortunately one of the nodes used as replacement is currently Offline so I have voted to reject.

Replace nodes in subnet tdb26

Motivation:

Calculated potential impact on subnet decentralization if replacing:

  • 1 additional node would result in: equal decentralization across all features and subnet topology penalty before 10 => 0 after the change
  • 2 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.3808
  • 3 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3808 to 3.4247
  • 4 additional nodes would result in: (gets better) the number of nodes controlled by dominant Country actors decreases from 15 to 14
  • 5 additional nodes would result in: equal decentralization across all features
  • 6 additional nodes would result in: equal decentralization across all features

Based on the calculated potential impact, replacing 4 additional nodes to improve optimization

Note: the heuristic for node replacement relies not only on the Nakamoto coefficient but also on other factors that iteratively optimize network topology.
Due to this, Nakamoto coefficients may not directly increase in every node replacement proposal.
Code for comparing decentralization of two candidate subnet topologies is at:

Note: the information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Here is an explaination of how decentralization is currently calculated,
and there are also instructions for performing what-if analysis if you are wondering if another node would have improved decentralization more.

Decentralization Nakamoto coefficient changes for subnet tdb26-jop6k-aogll-7ltgs-eruif-6kk7m-qpktf-gdiqx-mxtrf-vb5e6-eqe:

  node_provider: 12.00 -> 12.00    (+0%)
    data_center: 13.00 -> 13.00    (+0%)

             area: 8.00 -> 9.00   (+12%)
          country: 5.00 -> 6.00   (+20%)

Mean Nakamoto comparison: 10.83 → 11.17 (+3%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.4247

Impact on business rules penalties: 10 → 0

Replace nodes in subnet tdb26

Motivation:

Calculated potential impact on subnet decentralization if replacing:

  • 1 additional node would result in: equal decentralization across all features and subnet topology penalty before 10 => 0 after the change
  • 2 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.3808
  • 3 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3808 to 3.4247
  • 4 additional nodes would result in: (gets better) the number of nodes controlled by dominant Country actors decreases from 15 to 14
  • 5 additional nodes would result in: equal decentralization across all features
  • 6 additional nodes would result in: equal decentralization across all features

Based on the calculated potential impact, replacing 4 additional nodes to improve optimization

Note: the heuristic for node replacement relies not only on the Nakamoto coefficient but also on other factors that iteratively optimize network topology.
Due to this, Nakamoto coefficients may not directly increase in every node replacement proposal.
Code for comparing decentralization of two candidate subnet topologies is at:
dre/rs/decentralization/src/nakamoto/mod.rs at 79066127f58c852eaf4adda11610e815a426878c · dfinity/dre · GitHub

Note: the information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Here is an explaination of how decentralization is currently calculated,
and there are also instructions for performing what-if analysis if you are wondering if another node would have improved decentralization more.

Decentralization Nakamoto coefficient changes for subnet tdb26-jop6k-aogll-7ltgs-eruif-6kk7m-qpktf-gdiqx-mxtrf-vb5e6-eqe:

  node_provider: 12.00 -> 12.00    (+0%)
    data_center: 13.00 -> 13.00    (+0%)
data_center_owner: 13.00 -> 13.00    (+0%)
             area: 8.00 -> 9.00   (+12%)
          country: 5.00 -> 6.00   (+20%)

Mean Nakamoto comparison: 10.83 → 11.17 (+3%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 3.3525 to 3.4247

Impact on business rules penalties: 10 → 0

Business rules check results before the membership change:

  • Node provider cluster 1 (6sq7t, vegae, eatbv) has 2 nodes in the subnet

Proposal 137003 | Tim - CodeGov

Vote: Reject

This proposal replaces 4 nodes in subnet tdb26, appearing in the decentralization tool as “UP”, presumably for the purpose of preventing 2 nodes from an identified node provider cluster, although this is not indicated under “Motivation” in the proposal text. However, one of the replacement nodes (4nldz) is currently offline along with the vast majority of the nodes in the same data centre, with the remainder appearing as “Degraded”.

About CodeGov

CodeGov has a team of developers who review and vote independently on the following proposal topics: IC-OS Version Election, Protocol Canister Management, Subnet Management, API Boundary Node Management, Node Admin and Participant Management. The CodeGov NNS known neuron is configured to follow our reviewers on these technical topics. We also have a group of Followees who vote independently on the Governance and the SNS & Neurons’ Fund topics. We strive to be a credible and reliable Followee option that votes on every proposal and every proposal topic in the NNS. We also support decentralisation of SNS projects such as WaterNeuron, KongSwap, and Alice with a known neuron and credible Followees.

Proposal 137003 – LaCosta | CodeGov

Vote: REJECT

The proposal replaces 4 nodes on subnet tdb26:

  • Removed Nodes: node txh2c, Dashboard Status: Active, node wazkf, Dashboard Status: Active, node vysyd, Dashboard Status: Active and node rcxhc, Dashboard Status: Active

  • Added Nodes: node 467sz, Dashboard Status: Awaiting, node di4du, Dashboard Status: Awaiting, node 4nldz, Dashboard Status: Offline, node 3zfpk, Dashboard Status: Awaiting

The proposal not only aims to reduce the business rules penalties from 10 to 0 but also improves the decentralization with improvements of the Nakamoto coefficients area and country by 12% and 20% respectively.

However, one of the nodes used as replacement, node 4nldz is currently Offline with most nodes in it’s DC im2 having similar status.

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.

TLDR: Replace Seoul&HongKong nodes to improve decentralization. im1 is getting a 2nd try after previousely failed proposals due to offline issues. George Bassadone is replaced due to interconnection to Bianca but we have created another interconnection (see below).

Proposal 137003 Review | Lorimer :infinity: :dog_face: - CO.DELTA △

VOTE: NO

TLDR: Unclear what the proposal is even trying to achieve…

Based on the calculated potential impact, replacing 4 additional nodes to improve optimization

Just look at the map below to see the significant reduction in geographic decentralisation (red nodes are replaced with green nodes).

Additionally, 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:

The proposed subnet topology contains 2 nodes from the rpfvr+glrjs+spp3m cluster (more than 1 breaks the ‘independent party’ imperative that each subnet needs to adhere to). The nodes involved are:

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

  • 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.

Proposal #137003 — Zack | CodeGov

Vote: Rejected

Reason:
The proposal is meant to replaces 4 healthy online nodes in order to address the Node provider cluster 1 business rules issue but one of the proposed nodes from the IM2 DC is Offline 4nldz. There are still problems with that DC as other nodes are down or degraded as well.
