Johns Hopkins cryptography professor Matthew Green got into a heated X spat with security researcher @MalwareTechBlog. Green proposed a verification deal: the other side says it's impossible, Green says it's doable — they name a mutually trusted judge, Green hands over the evidence, and then clowns on his opponent. Green also accused the researcher of having done no basic research into these models, mocking "I used Claude once" as not counting as experience.
