Abstract

The aim of this study is to review the literature growth and author productivity of Blockchain technology research from 2008 to March 2017. 801 articles were retrieved from Scopus database and analyzed with bibliometrics approach using different perspective views. The author productivity was derived using the Lotka`s law and K-S test was performed to verify the reliability. The result indicates that the number of literatures on Blockchain is still increasing. Three stages of Blockchain research change were discovered. In 2008 to 2013, the topics were related to the Bitcoin and cryptocurrencies; in 2014 to 2015, the number of Bitcoin literatures grew rapidly; after 2016, a lot of researchers are paying attention to the techniques of Blockchain and smart contract. Moreover, the distribution of author productivity meets the study of Lotka. This study presents state-of-the-art and abstract the trend of Blockchain research regarding several perspectives of bibliometrics analysis.
