Due to the Chrysalis network update on Mainnet that happened April 28, 2020, many old questions/answers (particularly those around trinary encoding and Winternitz signatures, but also low-level questions about message format internals) became obsolete and only of historic interest.

How should we go treat them?

I noticed that Antonio Nardella started posting answers to those questions. I myself am tagging all those questions with the legacy-protocol tag when I stumble upon them.

But I believe we could need more coordination here. And maybe some tooling (if it exists) like a displayed banner to make it more obvious to newbies that those questions are not relevant to the IOTA network deployed today and only of historic interest.

EDIT As pointed out in the answer below, we could create a custom post notice for that. Any suggestions for the wording are appreciated :)

Hello and thanks for pointing that out!

I see that it looks like StackExchange has the option to add banners to questions enter image description here

Is it possible that such option is available in the moderation tools?

    That is a good idea. Moderators can toggle "post notices" for questions, but the notice itself would have to be created by StackExchange as a custom post notice for our site: meta.stackexchange.com/questions/191981/…
