      @patio11 question for you, what’s the way you publish SHAs for predictions (usually along the lines of: $CRYPTOASSET will be bankrupt by this date) as tweets? I have one I want to make about something else!

      Put the prediction in a text file on your local machine, from the terminal type "shasum -a 512 somefile.txt", tweet the output. Once you want to reveal prediction, reveal the exact text and point back at the tweet where you revealed the hash.

          Ah, clever. Honestly the least convoluted way to do this. You have any predictions you’ve come back to that you nailed?

          In that fashion, with hashes? Think I'm doing a pretty decent batting average on my tether stuff. https://twitter.com/patio11/status/1121572817353367552 … Part of the social purpose of tweeting a hash is to say "I've got *somebody* dead to rights." Loses some impact if you produce 100 predictions a day.

          Depending on whether you are doing this with counterparties who have done this before, you may need to give them command line which reproduces the hash (save to file, use above command) and the fact that you couldn't have hash on date you tweeted w/o having pre-written that text.

          Ofc, makes perfect sense. This is more for me putting an idea out there that is along a similar line of $ASSET will be worth zero and don’t think it’s fair to people working on it to say it... then again, it seems so appallingly obvious that I do want a record for it.

          Yes. But if you *need* your prediction to be secret, ensure you have enough (> 80 bits) of entropy (e.g. include some random characters). Otherwise, someone could bruteforce the prediction, i.e. try many X in “X will go to zero” (etc.) and check whether that gives the same hash.

          Great point, makes sense!
