Smartlock: controle de acesso através de smart contracts e smart property

Abstract

Blockchain is the technology that allows the transaction of money between parties in a peer-to-peer manner without the need of a trusted intermediary such as banks. This technology is known for its attractive characteristics: (i) the data integrity, and (ii) security. To take advantage of such characteristics, some blockchain networks are not focused on their cryptocurrency. One of those networks is the Ethereum network, which is a platform for smart contracts. Smart contracts are applications that represent an agreement between parties in a decentralized manner. These algorithms are deployed on the system and can be globally accessed. They are executed without the possibility of censorship, fraud, or external third party intervention. One of their possible applications is the smart property concept that is transacting property on the blockchain. This can be applied on the property rental context and the raising use of services such as AirBnB due to its financial attractiveness to its users, there is a need to develop a system capable of solving the security issues while providing comfort. This work will presents the development of a project that studies the viability of applying the concept of smart property. A reservation platform was developed where the user makes one reservation and, when approved, a smart contract is deployed to the Ethereum platform. To access the property, the user uses the application developed for Android which transfer the credentials using a data through sound protocol. The lock verifies these credentials accessing the smart contract and activates the lock’s circuit allowing access to the property. To examine the viability of this project, tests were performed with supposed users of this system who also answered a survey. After the analysis of this survey, the project proved to be viable, more attractive than the traditional standard, functional, and provided comfort.
