Systematic review of the literature, research on blockchain technology as support to the trust model proposed applied to smart places

Abstract

The smart places are vulnerable with corrupted or compromised data, with the false integration of new devices, and devices with firmware versions inconsistent. These risks worsen with the increasing volume and diversity of data, devices, infrastructures and users connected to the Web. The systematic review of the literature were selected 190 documents, which reveals the growing interest on the theme of blockchain technology with the publication of 14 documents in 2014 to about 100 already in 2017. The articles focused on the areas bitcoin (about 40%), IoT (about 30%), financial (about 15%), cryptocurrencies, electronic government (about 12%), smart contracts, smart cities, business (with about 10% each) and health (about 5%). This perspective confirms the generic model study data supported in blockchain technology for smart places, especially when applied to smart cities and the specific field of the mobility ecosystem, with the use of the new concepts of the application of blockchain in IoT, smart contracts and e-governance.
