Thanks for the detailed response - this is exactly the kind of domain expertise I need to hear. You're right that formal institutional workflows (courts, news organizations, professional photography) already handle chain of custody adequately through raw file retention and existing practices. I'm realizing my value proposition isn't for those contexts where authentication has always been critical and processes exist. Where I see the gap is informal authentication at scale - the billions of images shared daily on social media, used in online discourse, spreading as potential misinformation. Your workflow (keeping raw files, institutional backing, forensic analysis when needed) works great for professional contexts. But: How does the average person verify an image they see online? - They don't have access to forensic analysis - They don't know who has the "earliest/rawest version" - Trusted institutions are too slow to counter propaganda at internet speed - Even if institutions could authenticate on demand, would they scale to billions of images? Blockchain provides automated, scalable verification: platforms could flag images as "no blockchain record found - likely generated/manipulated" without human intervention. Can't generate false positives (hash either matches or doesn't). This doesn't replace institutional workflows - it augments them for contexts where those workflows don't exist. On the post-AI point: I actually think this is backwards. If we reach a world where we can't even prove "this camera captured this scene," then we have no ground truth at all. Hardware attestation becomes MORE critical, not less. Your blockchain record also includes geotags, timestamp, camera ID - significantly harder to forge a complete fake than just the image itself. Without some method of proving hardware capture, the only option is to stop using images for truth-verification entirely. On ubiquity: Every standard starts somewhere. HTTPS, GPS in cameras, seatbelts - none were ubiquitous until they were. Even before universal adoption, blockchain authentication can prove a positive ("this image has verifiable provenance") even if it can't yet prove a negative ("this image was generated"). For law enforcement, that's still valuable. On watermarking: Watermarks can be trained around - that's what GANs do. If you watermark with something requiring a key to decode, you're already halfway to cryptographic signing, just without blockchain's forgery resistance. They're complementary approaches, not competing ones. On qualitative vs quantitative: As an engineer, quantitative beats qualitative for anything requiring accuracy at scale. Expert judgment works for individual high-stakes cases but doesn't scale to internet-speed misinformation. You've helped me clarify that my audience isn't professional photographers with institutional backing - it's everyone else who needs to distinguish real from fake at the speed of social media. That's probably a harder problem to solve, but arguably more important given how information spreads today. Does that reframing make sense, or am I still missing key limitations?

If there’s a technological solution that could, somehow, provide a ubiquitous means of walking back from image discovered on the internet through the whole chain of custody to either a specific camera or a specific prompt, then yes there’s definitely a market and a need for that in society, and both the market and the need are going to be substantially greater, even after this AI-summer collapses, but I’ll be damned if I know how you’d get to the technical solution without first achieving the legal momentum necessary to make it ubiquitous enough to actually be useful for that grand of a purpose. It’s the chicken/egg problem, or maybe more accurately the “stuffing-everything—back-into-Pandora’s-box” problem. Humanity has already created sufficient original imagery without a blockchain (or whatever) technical provenance model to allow for an essentially infinite remixing of just that existing body of images we didn’t know we’d have a need for provenance for into an enormous corpus of slop we also don’t have provenance for. Yes it would be good if there already existed a blockchain containing a Markov chain back to every original work of natural intellect, but how do you build that while the models are already regurgitating and chewing the weights they’ve already learned? I mean I do think you’ve (also) noticed one of the wicked hard problems, it’s just I’ve had similar conversations in the photography and cinematography and VFX worlds going back more than 20 years, long before generative AI was a thing, but now they are a thing I think we’re stuck in a world where we need to understand that image + attestation != truth, and never really did. But if you do figure it out, and somehow there exists a future in which we somehow never let Schrödinger’s stinking cat out of Schrödinger’s stinking bag, I’ll be the first to invest.

  You're right that reaching full usefulness requires ubiquity, but achieving it requires solving adoption challenges that may be insurmountable. Billions of unauthenticated images already exist, but establishing truth going forward—even if only in certain areas—still has immense value. Your point that an authenticated image can still be a forgery through staging is correct. However, that's been true for much longer than our current crisis and the results have been far more manageable. Hardware attestation doesn't solve truth, but it's a necessary starting point. The honest answer: This solves a real problem, but implementation barriers may be insurmountable. I actually first imagined this framework over a year and a half ago and tried shopping it around, hoping a utility patent would motivate implementation. No one was interested in solving a problem with such a big question mark around reaching the end game. I'm publishing as prior art because if legal/regulatory momentum does emerge, I don't want authentication monopolized. But you're right to be skeptical. The fact you've had these conversations for 20+ years highlights the enormity of the problem. That said, we also haven't had blockchain for that long, and it's remarkably well suited to this application (way more than currency, in my opinion). If I figure out how to stuff everything back in Pandora's box, I'll let you know where to send the check.
