Análisis de factibilidad en la implementación de Blockchain sobre un prototipo de infraestructura IoT-MQTT

Abstract

The Internet of Things (IoT) has shown exponential growth in recent years. However, due to the limited resources and centralized architecture, there are difficult-to-solve problems such as centralized server overload, single point of failure, and possibility of malicious use of information. Blockchain presents unique features such as consensus mechanism, peer communication, trusted implementation without a reliable third party and smart contract-based transactions. These features seem to be suited to build a distributed and autonomous IoT system in order to overcome IoT issues. High processor performance, high bandwidth, and delays are not suitable scenarios for IoT, but are common in Blockchain applications. This research presents the feasibility of deploying Blockchain by considering IoT devices as Peer nodes on a Hyperledger Fabric network. Bandwidth measurements and performance tests were performed in transactional scenarios. Additionally, a high-level model for implementation of Hyperledger Fabric platform on IoT devices is proposed.
