Most of cryptocurrency wallet does not require identity verification in order to send, receive, and securely store your cryptocurrencies.

Verifying your identity is only used to helps prevent fraud and ensures that no one, except you, can use your payment information.
If you just make conversation or interaction with others, in the blockchain environments (like forums or chat rooms), do we also need verification?

That's clear.

If you claim your self as someone in real life, yes - you have to verify and proof it. If you don't, then you don't have to. As simple as that.

Especially if someone feels important to identify everyone in a blockchain environment for any reason, it is an extraordinary setback of ideas.
