Calling @polymutex.eth This cast reminded me of your story from a couple days back. I’m no fan of Musk and this screenshot seems believable based on verifiable past behaviour from Musk, so there is a threat of confirmation bias here. It could be a fake account or a fake image entirely. Short of me trawling through Twitter myself to confirm something which is pretty immaterial to my life. How could the original caster use EAS or ZK Proofs to provide verification that this image is genuine when casting? If it’s not possible today, what are the roadblocks?

All the pieces to make this work exist and work in theory, but no one has hooked them up all together to make this a reality in practice. You need: 1: A way to retrieve tweet data from X 2: A way to post them onchain in a way that everyone can tell they came from X 3: A way to prove that they match a screenshot ⤵️

Steps 1 and 2 are handled by @tlsnotary or zkTLS or @reclaimprotocol. Any of them allows you to make an HTTPS connection to a website (in this case X) and post the contents of what you retrieved through this connection onchain, in such a way that all can see that the content was verifiably retrieved from X. ⤵️

One challenge in this screenshot's case is that you don't need just one tweet, you need 2, and need to prove their relationship to each other (one is a reply of the other). This is difficult because X has forbidden logged-out users from retrieving more than 1 tweet at a time, and shut down the API for doing so. ⤵️

That said, you can still prove the existence of the tweets individually, and probably to prove that the second one is a reply (because the "reply to" data may still be on single-tweet pages). So let's assume we get past this problem. Having an onchain proof is good, but how do we surface this to actual humans? ⤵️

This is where it gets a bit hairy. The image is a set of pixels and it's pretty blurry. It's not obvious to a computer that these pixels are text, and that the text is two tweets, and that these two tweets correspond to onchain proof data that these tweets exist. Multiple ways we can go about that problem. ⤵️

The easiest way is that the original poster of the screenshot is a well-intended person and voluntarily posts the proof of the tweets' existence as part of their cast along with the screenshot. In this case it is easy for the Farcaster client to show this data and display it next to the cast. ⤵️

If the original poster did not post this proof and just posts the screenshot, this is where it gets harder. We need some way to link up the two together. The easiest way is for some good person to come along and create+post the proof that the original poster didn't. But that takes work. Can we automate this? ⤵️
