   - the reason for splitting is that each level of the path can have a max value of 2<sup>32</sup>-1 
   - the reason for using the peer's (`Bob`) public key is to always arive at the same value even if prio state is lost

- When client `Alice` wants to build its `dm parent key` for `Bob` it has to:
-  - get the public key of `Bob` (in hex). Eg: `3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d`.
-  - split the public key hex string in 8 chunks:
-       - `3bf0c63f`, `cb934634`, `07af97a5`, `e5ee64fa`, `883d107e`, `f9e55847`, `2c4eb9aa`, `aefa459d`
-  - derive the `dm parent key`: `m/25709'/1237'/3bf0c63f'/cb934634'/.../aefa459d'`
