* `rln` is used with hardcoded memberships, to avoid the sepolia node + contract, [see](https://raw.githubusercontent.com/waku-org/nwaku/master/waku/waku_rln_relay/constants.nim).
* Focused on measuring message propagation delays. Each message that is sent, encodes the timestamp when it was created.
* Same setup can be reused with different parameters, configured either via flags (see `shadow.yaml`) or modifying the code (see [simulations](https://github.com/waku-org/nwaku/tree/simulations)).
* TODO delay + bandwidth TODO add payload messages.
* Requires significant resources to run (tested with 256 GB RAM)
* Uses `100ms` of latency and `10Mbit` connection per node.
