• achieved: waku rln is not an experimental feature anymore, and is part of nwaku code base. from now on experimental features are hidden behind a flag and not in different build

chore: do not advertise multiaddr with port 0 {bug}

• achieved: tested two different solutions: updating the port with an addressMapper, and not allowing the user to use port 0. Analyzed and discussed technical implications of both solutions. Initially followed decision to proceed with 2nd solution for now, with intention of implementing the first solution in the future.
  • Opened a draft PR and updated tests for the solution of not allowing the user to choose port 0.
• next: after further feedback received today, we have to complete the discussion of how to move forward and either review and proceed with current PR, or plan and implement solution that updates all the data structures consistently across the node

  • Validated and tested “happy paths” of the solution, raised draft PR and got feedback about the solution
