      This is the SHA512 hash of a text file. It is impractical ("beyond the limits of modern science") to produce any text file which has exactly that hash unless you have exactly the text I have. It will be checkable, at some point in future, that a text corresponds to that hash.

          The social norm in some communities around this is to publish a hash in a visible place to claim "In a future where I publish the file, this is proof positive I had it as of publication of the hash."

          It’s an option to authoritatively say “look, I was right” in the future if the prediction pans out, while avoiding the social consequences of stating the prediction in the present.

          So you've made some kind of prediction, that you will share later, and we can confirm you made today?

          Or he has broken SHA512. 🤷🏼‍♂️

          What if the prediction is, “I have discovered a collision attack for SHA512”? ;)

          If you figured out a way to produce two sentences of opposing meaning with the same hash we need to know that 😬

          The hash preimage explains that pretty clear

          I take some comfort from the fact that twitter still exists in the future where this text file can be evidenced as verified (I think)

          Why not just publish this in base64 encoding, that way you would have said it but not said it :)
