# Replace nodes in subnet pzp6e

Motivation: Increasing the size of the Fiduciary subnet to get it aligned with the target topology
 - removing xsntz-cuxb5-c3xmg-vuzwb-2wsb6-jbfpj-jh6du-ynics-ziore-t7bpp-4ae as per user request
 - adding w7v5s-nethv-crfsc-zzq5e-gibjz-dmmyp-mrl6e-vkvid-g56eh-iilcm-eqe as per user request
 - adding jlifv-mddo3-zfwdc-x2wmu-xklbj-dai3i-3pvjy-j4hqm-sarqr-fhkq6-zae as per user request
 - adding u3ahx-ft3kq-pzlkr-imzus-aeqxm-cirqv-ymehh-xzctz-os4ud-3a74m-vae as per user request
 - adding mhfef-zbxsl-rocpc-ovqeh-jg3ct-7nvmi-gzpnm-xjmm4-uekgj-rquls-uqe as per user request

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 https://github.com/dfinity/dre/blob/79066127f58c852eaf4adda11610e815a426878c/rs/decentralization/src/network.rs#L912

Decentralization Nakamoto coefficient changes for subnet `pzp6e-ekpqk-3c5x7-2h6so-njoeq-mt45d-h3h6c-q3mxf-vpeq5-fk5o7-yae`:
```
  node_provider: 10.00 -> 11.00   (+10%)
    data_center: 10.00 -> 11.00   (+10%)
data_center_owner: 10.00 -> 11.00   (+10%)
            city: 10.00 -> 9.00   (-10%)
          country: 4.00 -> 4.00    (+0%)
        continent: 2.00 -> 2.00    (+0%)
```

**Mean Nakamoto comparison:** 7.67 -> 8.00  (+4%)

Overall replacement impact: (gets better) the average log2 of Nakamoto Coefficients across all features increases from 2.7146 to 2.7580
