Hi @conr2d is varsig something you are planning to use? Unfortunately we've stopped working on this standard and currently don't have any plans to restart the work.

cc @bumblefudge maybe it's time to archive the repo?

@oed Thank you for letting me know about the project's discontinuation.

I have a project that uses various DSA and it's crucial to keep the data size small. I think using Multikey would work for cryptographic public keys, but for digital signatures, I haven't found a stabilized specification.

With this project's discontinuation, will the 0x34 varsig entry be removed from multicodec? If it remains, it seems like it would be still suitable for my use case.

@conr2d this project is not discontinued. @oed just meant that Ceramic is not using it.

@bumblefudge please see the above comment (RE do not archive)
