RT Journal Article SR Electronic T1 Blockchain: Data Malls, Coin Economies, and Keyless Payments JF The Journal of Alternative Investments FD Institutional Investor Journals SP 8 OP 16 DO 10.3905/jai.2018.21.1.008 VO 21 IS 1 A1 Zura Kakushadze A1 Ronald P. Russo, Jr. YR 2018 UL https://pm-research.com/content/21/1/8.abstract AB The authors discuss several uses of blockchain and, more generally, distributed ledger technologies outside of cryptocurrencies. They take a pragmatic view, focusing on three main areas: the role of coin economies for “data malls” (specialized data marketplaces), data provenance (a historical record of data and its origins), and “keyless payments,” which are payments that can be made without having to know other users’ cryptographic keys. They also discuss voting and other areas and give a sizable list of academic and nonacademic references.TOPICS: Currency, quantitative methods
