As of June 2023, the U.S. government was both alarmed about deepfakes and trying to outlaw blockchains.

Judge as of June 2023. The claim has two parts: (a) the US government was alarmed about deepfakes and (b) the US government was trying to outlaw blockchains. True: evidence shows official US government concern about deepfakes (e.g. statements from the White House, FTC, DHS or Congress, or bills introduced) and actual efforts by US government bodies to ban or prohibit blockchain technology or cryptocurrencies as such. Mostly true: (a) holds and US agencies took broad actions aimed at eliminating major parts of the crypto industry (e.g. the SEC treating most tokens as illegal securities, 'Operation Choke Point 2.0' banking pressure) that could fairly be called trying to outlaw them, though there was no formal ban. Mixed: (a) holds, but (b) is supported only by enforcement actions and regulation of specific firms, not an effort to outlaw the technology. Mostly false: (a) holds but (b) is clearly contradicted, with no ban effort and policy focused on regulating rather than prohibiting. False: neither part is supported.

8. E8 Blumenthal played his own deepfake to warn Congress about the dangers of AI CT Public · 17 May 2023

   ““Weaponized disinformation, housing discrimination, the harassment of women and impersonation fraud, voice cloning, deep fakes,” Blumenthal said.”

Part (a) is supported: in May 2023 Senator Blumenthal warned Congress about AI harms including deepfakes (E8). For part (b), the SEC Chair stated in June 2023 that the vast majority of crypto tokens meet the investment contract test and that most crypto intermediaries must comply with securities laws (E1, E2). This matches the criteria's 'mostly true' example of the SEC treating most tokens as securities. However, the same remarks frame this as registration and compliance rather than prohibition, and mention no-action relief (E5, E6, E7). No evidence shows a formal ban on blockchain technology.
