Would be really great to have it on the upcoming RISC-V secure hardware, that should be released soon.

Then we would have open hardware implementation of this on a open application core as well.

Thank you so much for open sourcing this!

Are you involved in any ways? Do you know if there are developer previews available?

Not really involved. Just fascinated.

I don't know of that actually happening officially but probably you can.

See: https://keystone-enclave.org/

MIT worked before on Sanctum that you might want to look at, its sort of the pre-version of what keystone will be. See: https://eprint.iacr.org/2015/564.pdf

I'm not from America, can you please explain what "early Fall" means?

Changing the website to an approximate month or a quarter would be fantastic for those of us not from that side of the world.

Early fall should be around end of September - through October

Yes. We're still defining the exact date, but it should be within the next two weeks.

We're working on some really exciting partnerships, we need a few more days to finalize details. So far we're super excited about how the campaign is coming up!

Many thanks!

Has it been cross compiled for Tomu.im ?

Tomu, being a ARM M0 core, might take some time to compute ECC signatures, but it is probably fine in practice.

Our code is designed to be small and portable, so I think it could easily be run on the Tomu. Just need some work to change the USB drivers stuff.

Not that I'm aware of. Might be trickier than U2F (that exists already) because FIDO2 is a bit more computationally expensive, and probably larger code base. But certainly an interesting project to add to the pipeline.
