if you are writing a white paper or any paper for that matter, then forum format of quoting and citing is not for you.
you don't copy-paste a whole text in a paper and then simply reference it, it will look unprofessional.
what you need to do is somehow paraphrase it and then cite it, without having to use the quotation mark.
if you look at "Bitcoin: A Peer-to-Peer Electronic Cash System" paper >
https://bitcoin.org/bitcoin.pdf notice how he used this reference >
http://www.weidai.com/bmoney.txt on the second page , but you can't find the exact text on the reference, however the idea or the theory is there.
so what you basically need to do is ,use numbering like [1] after a paragraph / sentence which you used , and then at the bottom of the paper add those references.
you could still copy-paste exact text, put it in a double quotation format but you will still have to include the references with the same format as explained above.
you can also get some more information here >
