Mobilidade urbana descentralizada: proposição e estudo de caso de um modelo baseado em tecnologias distribuídas

Abstract

This dissertation proposes a decentralized model for urban mobility, grounded in blockchain technology as a digital infrastructure aimed at promoting transparency, security, and interoperability among different modes of transportation. Based on the current state of the art, the proposal seeks to be materialized through a decentralized application (dApp) integrated with a digital wallet, enabling users to register, validate, and share mobility data securely and audibly via interaction with smart contracts deployed on test networks. The study begins by analyzing recurring structural challenges in Brazilian urban centers, such as service fragmentation, centralized data management, and the lack of reliable user-side verification mechanisms. In response, a Minimum Viable Product (MVP) is presented, consisting of a dApp and a smart contract deployed on the Ethereum Testnet, aiming to demonstrate the technical feasibility of a decentralized architecture. The methodology proposed by Bruno Munari for project structuring guides the development process through accurate problem identification, hypothesis formulation, and the construction of a functional prototype. This results in a user-centered proposal with technical potential, aligned with the principles of innovation, functionality, and practical applicability in the context of urban mobility. The model proposes to integrate the concepts of Smart Cities, Mobility as a Service (MaaS), sustainability, and Artificial Intelligence of Things (AIoT), offering a modular, scalable, and user-oriented alternative for the digital transformation of urban mobility. Finally, the proposal aims to highlight potential benefits for urban mobility management, such as reducing service fragmentation, strengthening trust in transactions, and encouraging sustainable practices. Additionally, it intends to contribute to both academic and practical fields by presenting guidelines, tools, and preliminary evidence that support the use of emerging technologies — such as blockchain, MaaS, and AIoT — in building smarter, more integrated, and citizen-centered cities.
