The thought came to my mind, when everything about Bitcoin and Ethereum is legit open-source, and posted on GitHub; there's every line of code available in the open for any government to make a Bitcoin/ Ethereum clone of their own. So, whey aren't they doing that, if not seriously, then at least proof-of-concept?
Even if blockchains come with patents, there's the phrase called 'compulsory licensing' that has long been used by third world countries to manufacture patented drugs at dirt-cheap prices. Likewise, blockchains too could be 'compulsorily licensed' even if patented.
open source code from Bitcoin and Ethereum has received public attention and recognition, it would be embarrassing if the government plagiarized the Bitcoin/Ethereum open source code and I think they don't have a strong goal to use it
Whey then doesn't any country, say China or India, declare such a blockchain to be an essential 'public good' and clone Bitcoin or Ethereum, whatever is utilitarian for their purposes? At least they'll save on the Ether prices for their DApps!
I doubt they have any intention to save it because Ether price is very cheap for them, it's not a problem for the government if they want to make Dapps
