“…c) The contract layer is designed to contract the service process, including both consensus and incentive and punishment mechanisms. The consensus mechanism is consistent with the consensus mechanism of the underlying blockchain, and all kinds of nodes are ranked according to the active level and task completion degree [27]. According to the accuracy and fairness of the results of the consensus mechanism, this framework can achieve good audit performance.…”

Recently, cybersecurity becomes more and more important due to the rapid development of Internet. However, existing methods are in reality highly sensitive to attacks and are far more vulnerable than expected, as they are lack of trustable measures. In this paper, to address the aforementioned problems, we propose a blockchain-based cybersecurity framework, termed as Sapiens Chain, which can protect the privacy of the anonymous users and ensure that the transactions are immutable by providing decentralized and trustable services. Integrating semantic analysis, symbolic execution, and routing learning methods into intelligent auditing, this framework can achieve good accuracy for detecting hidden vulnerabilities. In addition, a revenue incentive mechanism, which aims to donate participants, is built. The practical results demonstrate the effectiveness of the proposed framework.

“…Para resolver o problema de falta de confiança entra os nodos de uma blockchain, foram desenvolvidos algoritmos de consenso para que apenas um bloco seja inserido por vez na cadeia. Segundo [Watanabe et al 2015] um algoritmo de consensoé um conjunto de regras que permite que os usuários cheguem a um acordo mútuo. Atualmente o algoritmo mais utilizado em blockchainsé chamado de Proof-of-Work (POW).…”

Nos últimos anos houveram diversas propostas visando a centralização e manipulação de dados de saúde, como prontuário eletrônico do cidadão. Por se tratarem de dados altamente sigiloso, problemas de como garantir a confidencialidade dos dados sempre foram um entrave. O surgimento de tecnologias como blockchains e smart contracts vem trazendo novas abordagens possı́veis na manipulação desses dados. Este trabalho apresenta uma proposta de utilização de blockchain em conjunto com smart contracts para centralização e compartilhamento de dados de saúde. Experimentos preliminares demonstraram a viabilidade do armazenamento e recuperação dos dados de forma segura, através da utilização de dois pares de chaves assimétricas.

This paper has reviewed the blockchain domain that suits with the current Industrial Revolution (Industry 4.0) uses cryptographic method blockchain. The implementation of this new cryptographic method in Industry 4.0 is currently being used widely as it eases the process of financial transaction and other process that have been as issue related with cyber security. The collection of review papers shows that the blockchain technology has high potential to grow wider not just in financial technology services and manufacturing industry but also in public sector, health care and even media industry. The papers elaborate how the blockchain able to be applied in different fields of technology in order make a secure and more protected services without entrusted the third party to avoid vulnerability to be attacked and misused. Nevertheless, the applications of the blockchain in various field helps in making the industry revolution.
