Replace nodes in subnet tdb26
Motivation:
- replacing ltzjy, swzzz, 74qsa: We have found no evidence that justifies the offboarding of node providers. However, as a precautionary measure, and to allow more time for discussion around potential node provider collusion, we are submitting a selected set of node swap proposals for critical subnets. Please note that this may slightly reduce the Nakamoto coefficients.
NOTE: The information below is provided for your convenience. Please independently verify the decentralization changes rather than relying solely on this summary.
Code for calculating replacements is at dre/rs/decentralization/src/network.rs at 79066127f58c852eaf4adda11610e815a426878c · dfinity/dre · GitHub
Decentralization Nakamoto coefficient changes for subnet tdb26-jop6k-aogll-7ltgs-eruif-6kk7m-qpktf-gdiqx-mxtrf-vb5e6-eqe:
node_provider: 11.00 -> 12.00 (+9%)
data_center: 13.00 -> 13.00 (+0%)
data_center_owner: 12.00 -> 13.00 (+8%)
area: 10.00 -> 8.00 (-20%)
country: 6.00 -> 5.00 (-17%)
Mean Nakamoto comparison: 11.00 → 10.83 (-2%)
Overall replacement impact: (gets worse) the average log2 of Nakamoto Coefficients across all features decreases from 3.4098 to 3.3525
Impact on business rules penalties: 120 → 80
