“…Authors deeply reviewed 64 papers identifying some gaps but, there is no mention about testing. Leka et al [35] develop an SLR but the authors follow the SMS method mentioned earlier, they do not follow the SLR process. Moreover, no explanation about the execution is described and results cannot be reproducible.…”

Blockchain technology promises to spark a real revolution. One of most important concepts associated with this technology is smart contracts, which enable the automatic execution of agreements and augur a world without intermediaries. The conditions and rules of "contracts" are established in a computer codes and trust is enforced by consensus among the participants. One relevant feature associated with smart contract is the immutability property, which establishes the non-alteration of blockchain network data after the clauses of the contract are been approved by all parties or entities involved. For this reason, smart contract development requires more effort and care than the development of other common programs. They require systematic mechanisms to collect requirements and functional specifications. In addition, it is necessary to verify and validate the agreed functionality and the implemented code before they are deployed in the blockchain platform. This paper presents a systematic literature review of primary studies in the field of Software Development Life Cycle, focusing on model-based software design and testing in the blockchain domain of smart contracts. This research aims to identify gaps and/or opportunities for further research. After carried out this review, it was observed that no clear methodology exists for evaluating and validating the quality either of this software or the overall development process. This means that software developers may implement smart contract code in which bugs and serious security vulnerabilities appear when the software is delivered to their customers.

“…Blockchainé uma solução de DLT (Distributed Ledger Technology) que define uma rede de transações distribuídas em que os nós transferem blocos de informação, contendo identidade e conteúdo, de forma P2P (Peer-to-Peer) [52], [53]. Devido a ser uma rede descentralizada, que provê privacidade, rastreabilidade e controle de acesso, vem sendo usada em váriasáreas, especialmente criptomoedas e contratos inteligentes (smart contracts).…”

A ampla adoção do conceito de Internet das Coisas (IoT) passa por aumentar a confiabilidade e a disponibilidade das suas aplicações perante falhas. A heterogeneidade dos componentes IoT, aliado a dispositivos limitados computacionalmente e integrados a Internet, impõe desafios adicionais para alcançar a tolerância a falhas. Nesse contexto, é essencial investigar como a tolerância a falhas pode ser eficientemente desenvolvida em IoT. Este trabalho apresenta uma revisão sistemática da literatura sobre as principais técnicas e soluções de tolerância a falhas desenvolvidas nesse contexto. Dos 2.004 trabalhos encontrados nos últimos 5 anos, 44 respondem diretamente a questão de pesquisa formulada e são categorizados de acordo com a estratégia de tolerância a falhas utilizada. A análise dos resultados apresenta soluções aplicadas ao dispositivo, conectividade, nuvem e borda, arquiteturas tolerantes a falhas e blockchain.

“…The key advantages of blockchain identified in [22] include decentralization, persistency, non-repudiation, anonymity, and auditability. Some of the most common vulnerabilities are end point vulnerabilities, public and private key security, blockchain integration platforms, untested at full scale, lack of standards and regulation, and untested code and vulnerabilities on smart contracts.…”

Distributed and collaborative computer-aided design (CAD) environments include building information modeling (BIM) and geographical information systems (GISs) in civil engineering and architecture, or product data management/ product life cycle management (PDM/PLM) in mechanical engineering. It is essential to keep the data integrity in these computer applications as it contributes to building users' confidence in CAD/BIM/PDM data. Blockchain technology, the core foundation of cryptocurrencies, is increasingly being used for other purposes and could solve the data integrity issue in collaborative CAD environments. However, it has some disadvantages such as the transparency of data and the slowness of storing data in the blockchain due to distributed consensus. Increasing demand by the Industry 4.0, IoT, Smart Cities, and other initiatives could foster the best what blockchain has to offer: data integrity, reliability, and traceability. This chapter explains how blockchain works, how can it be utilized in distributed CAD environments, what are the major challenges for implementation, and how CAD vendors could use it to increase CAD data integrity.
