Well, this thing that he mentioned, Ledger, is a peer-reviewed journal for the cryptocurreny space that was recently announced.
That thing is for academics. People who sit writing scholarly articles for scholarly journals all day so they can score a few points from others who are busy doing exactly the same.
Evan is not an academic, he's an entrepreneur. If he puts anything down on paper at all it'll be for practical purposes to achieve a practical result. Having spent some time in academic institutions I wouldnt hold much store over the value of getting a peer review from there thats anything other than a tyre kicking exercise thats rendered obsolete within weeks by new developments.
Dash is not a research activity. It's an entrepreneurial software project with well specified objectives defined by the age old properties of money, not academics. You can code it anyway you like as long as it meets those requirements and does so reasonably securely. Don't worry - it will get critical appraisal alright (with the emphasis on 'critical'). It'll probably even get academic 'critical appraisal', but it's not the subject of 'scholarly journals', it's the subject of the commercial realm.
