TY - JOUR T1 - Blockchain: <em>Data Malls, Coin Economies, and Keyless Payments</em> JF - The Journal of Alternative Investments SP - 8 LP - 16 DO - 10.3905/jai.2018.21.1.008 VL - 21 IS - 1 AU - Zura Kakushadze AU - Ronald P.

They also discuss voting and other areas and give a sizable list of academic and nonacademic references.TOPICS: Currency, quantitative methods ER -
