Re: the OpenTimestamps grant request, the problem is right now while the protocol scales in theory, the backend does not. It would be quite easy for a bad actor to DoS attack OpenTimestamps out of existence because I simply can't throw servers at the problem: the backend code just doesn't scale. I need funding to put in a bunch of hours to fix this. So far, no luck in finding that; OpenSats is one of a few sources I've tried. Frankly, I suspect that there isn't actually much interest in time-stamping.
