Currently, there is no tag for "secp256k1".

Given how important Bitcoin has become, it might be time to have such a tag.

Doing so would make it easier for users to find and answer secp256k1-related questions.

  • $\begingroup$ I've changed the tags from feature request to discussion / voting, as anybody with enough rep can introduce such a tag, so no mod or team operation is required. $\endgroup$ – Maarten - reinstate Monica Jul 16 at 12:43

No, we should not introduce a secp256k1 tag. Just tagging something with and / or is enough.

Yes, we should introduce a secp256k1 tag. This specific curve has become important enough to merit its own tag.

b degnan: Besides that, people may not know that secp256 would be related to ECC and DSA.

  • $\begingroup$ A large number of users will know secp256k1, but they might not know it is associated with a Koblitz curve. "Secp256k1" is one of the curve options in GPG, and some users may know it from there and want to follow its questions and answers on this site. $\endgroup$ – Patriot Jul 17 at 11:35
  • $\begingroup$ Then what about secp192k1? It exists. Will there be a tag explosion for every "popular" named curve? $\endgroup$ – forest Jul 20 at 7:10
  • $\begingroup$ secp256k1 is much more noteworthy than secp192k1. I can name several major applications of secp256k1 off the top of my head; I can't name any for secp192k1. $\endgroup$ – Squeamish Ossifrage Aug 23 at 16:29

No, we should not introduce a secp256k1 tag. Just a single curve specification is too specific to merit a tag of its own. Instead we could introduce a tag, as the curve is associated with a Koblitz curve.

    $\begingroup$ What about having secp256k1 which is an alias to koblitz? $\endgroup$ – forest Jul 17 at 2:37
  • $\begingroup$ Interesting idea. Maybe I'm taking this too literally, but I don't like the idea because secp256k1 is obviously not an alias of it, it's a specialization of it... Do you want me to introduce another answer for it or shall we check if this one gets voted up and decide then? As I don't think they can win separately I'd suggest the latter. $\endgroup$ – Maarten - reinstate Monica Jul 17 at 11:37
