Integração da tecnologia blockchain em rede de sensores IoT

Abstract

The Internet of Things (IoT) and Blockchain are two revolutionary areas that are transforming the way society interacts with the digital world. When combined, these technologies can create powerful solutions for various problems. IoT refers to the interconnection of physical devices that can collect and exchange data over the internet, which has the potential to revolutionize a wide range of sectors, including agriculture, healthcare, manufacturing, and smart cities, through devices such as sensors, cameras, meters, vehicles, and more. Blockchain technology is known for its ability to provide an immutable and secure record of transactions, consisting of a chain of interconnected blocks, where each block contains a record of transactions that is protected by cryptography. Once recorded in a block, the information cannot be retroactively altered, thus ensuring the integrity of the information. One of the main challenges of IoT is ensuring the security and privacy of information, with millions of interconnected devices on the internet collecting and transmitting information, making vulnerability and unauthorized data manipulation a critical concern. In this scenario, the characteristic of Blockchain is applied to IoT. This work brings a new perspective on how IoT can be enhanced through Blockchain technology, addressing a simple and effective solution using the Bitcoin protocol. The system will use blockchain technology in a small sensor network for Internet of Things (IoT) applications, automation, and smart environments, combining the basic features of an Arduino Uno microcontroller with an Android smartphone integrated with a custom Bitcoin wallet application. By integrating these components, the system capitalizes on the inherent benefits of blockchain, allowing for secure and transparent data management within the sensor network. This innovative approach opens new possibilities for enhanced data integrity, decentralized control, and seamless integration of the sensor network with the blockchain.
