Replace nodes in subnet csyj4
Motivation:
- replacing node wbqzc-cvi3c-gnuak-ztcqs-j4ga3-6m64f-w2fmy-qjqve-lzvja-rfir7-kae to optimize network topology
- replacing node 3smci-63tqe-6q5xc-wpdmj-pnhan-own4t-6km2r-77mfh-c2h7d-xzunk-cqe to optimize network topology
Calculated potential impact on subnet decentralization if replacing:
- 1 additional node would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.0763 to 2.2146 (solution penalty: 10)
- 2 additional nodes would result in: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.2146 to 2.2683
Based on the calculated potential impact, replacing 2 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 csyj4-zmann-ys6ge-3kzi6-onexi-obayx-2fvak-zersm-euci4-6pslt-lae:
node_provider: 5.00 -> 5.00 (+0%)
data_center: 5.00 -> 5.00 (+0%)
data_center_owner: 3.00 -> 5.00 (+67%)
area: 5.00 -> 5.00 (+0%)
country: 3.00 -> 4.00 (+33%)
Mean Nakamoto comparison: 4.33 → 4.83 (+12%)
Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.0763 to 2.2683
Impact on business rules penalties: 10 → 0

Business rules check results before the membership change:
- data_center_owner Digital Realty controls 2 of nodes, which is higher than target of 1 for the subnet. Applying penalty of 10.
