[Nfd-dev] Help needed with debugging duplicate Nonce

[Junxiao Shi]

Hi Ashlesh

This typically means either the design or the implementation is wrong. You
may find design problems through theoretical analysis; you may find
implementation problems through unit testing.
Also, don't combine two different features into the same commit. They need
to be in two separate commits, as they don't depend on each other.

Yours, Junxiao
