> Additionally I believe there are still restrictions on the export of strong crypto. That might be true, however exporting strong crypto is easily achieved by publishing the source code in a textbook, which is exactly what the Author of PGP did back in the days. At this point the goverment probably wouldn't dare file criminal charges for exporting strong crypto, because said crypto would probably be published under the 1st amendment. https://en.wikipedia.org/wiki/Export_of_cryptography_from_the_United_States https://en.wikipedia.org/wiki/Export_of_cryptography_from_th... https://en.wikipedia.org/wiki/Pretty_Good_Privacy#Criminal_investigation https://en.wikipedia.org/wiki/Pretty_Good_Privacy#Criminal_i... But it's a red herring, because in present day modern crypto in the sense of a munition is so far ahead of what block chain technology actually uses that it's a moot point. We are developing quantum resistant cryptography that moves away from traditional ideas. Like for example, RSA modular arithmetic that can be done concurrently by a quantum computer. https://en.wikipedia.org/wiki/Modular_arithmetic https://en.wikipedia.org/wiki/Modular_arithmetic https://www.youtube.com/watch?v=12Q3Mrh03Gk https://www.youtube.com/watch?v=12Q3Mrh03Gk > You would think that freedom of expression would cover that but it does not. It does, at least in terms of source code. Same issue with 3D printed firearms, the source code is free expression. However, taking the source code and printing/machining a ghost gun is an entirely different topic. Same goes for blockchain, but it's nuanced. If somebody perceive cryptocoin as a kind of financial "Securities", then the exchange of crypto could be regulated as commerce. But what if the exchange is not financial? What if a blockchain doesn't have any "platform" to regulate, such as services that trade crypto for ccurrency? What if I use a blockchain to publish a book, for instance the source code of the blockchain itself could be in the blockchain. We start to see paradoxes and circular reasoning. Blockchain schemes have both commercial speech, and regular speech.
