“…e construction of a national smart grid industry not only involves social issues such as people's livelihood and national defense but also shows the strength of the new energy strategy, which promotes the application of blockchain technology to social and environmental problems. Blockchain technology can reduce economic costs to a large extent, which will make it easier to control financial costs [30], reduce power generation production costs, and improve power infrastructure utilization efficiency [21].…”

Based on the diffusion of blockchain technology in the smart grid, this paper studies the framework and application of the blockchain technology in the smart grid, so as to combine the blockchain with the smart grid and establish a sustainable supply chain. However, the establishment of a sustainable supply chain is based on a layered theoretical framework. Not only should the framework take into account needless attributes and the relationship among various criteria and aspects but the application should also involve a balance of multiple stakeholders. For the above reasons, this paper uses a combination of Fuzzy-DEMATEL and ISM. The results show that (1) the hierarchical path of sustainable supply chain management of the smart grid under the blockchain starts from the social level, pays attention to system construction, grasps the technical standards, and defines the development goals of the power grid. (2) The development of green energy has become a new market growth point. (3) The control of the operation level becomes the focus of the smart grid. (4) The optimization and development of the economic structure are restricted by social factors. By integrating and optimizing the blockchain and supply chain, this paper puts forward a theoretical framework, establishes a sustainable GIP application system with multistakeholder participation at the supply chain level, and indicates the significance of the blockchain in the smart grid.

“…Audit logs are themselves a key target for an attacker who needs to erase any trace of their malicious activities; otherwise, they may get caught and then possibly prosecuted. The need for securing audit logging was raised already in different contexts, including hardware [3]; systems [4,5]; file systems [6]; databases [7]; secure logging protocols [8]; distributed systems [2,[10][11][12][13][14]; blockchain [1,[16][17][18][19][20]; and blockchain hardware [28], as well as many others. In this section, we describe some pieces of research in securing audit logging, with particular attention on distributed systems and cloud computing; we describe blockchain-based mechanisms later in the following subsection.…”

“…Chowdhury et al presented an analysis, reporting that blockchain can be applied to more critical scenarios [15]. Due to the transparency offered by blockchain technology, there is an increasing number of new mechanisms that use this technology for audit logging [1,[16][17][18][19][20]. We have found that these solutions, however, do not show enough detail about how the transactions are formed through smart contracts.…”

RootLogChain: Registering Log-Events in a Blockchain for Audit Issues from the Creation of the Root

Logging system activities are required to provide credibility and confidence in the systems used by an organization. Logs in computer systems must be secured from the root user so that they are true and fair. This paper introduces RootLogChain, a blockchain-based audit mechanism that is built upon a security protocol to create both a root user in a blockchain network and the first log; from there, all root events are stored as logs within a standard blockchain mechanism. RootLogChain provides security constructs so as to be deployed in a distributed context over a hostile environment, such as the internet. We have developed a prototype based on a microservice architecture, validating it by executing different stress proofs in two scenarios: one with compliant agents and the other without. In such scenarios, several compliant and non-compliant agents try to become a root and register the events within the blockchain. Non-compliant agents simulate eavesdropper entities that do not follow the rules of the protocol. Our experiments show that the mechanism guarantees the creation of one and only one root user, integrity, and authenticity of the transactions; it also stores all events generated by the root within a blockchain. In addition, for audit issues, the traceability of the transaction logs can be consulted by the root.

“…In contrast to our work, however, they focused on the case where other 'miners' (peer-to-peer nodes) are themselves the malicious attackers whereas we focus on securing the logs from an attacker outside the blockchain. Another closely related recent work [28] considered using a blockchain to store log files though there the authors used different frameworks and made alternative choices from those we make here [29].…”

A reliable log system is a prerequisite for many applications. Financial systems need to have transactions logged in a precise manner, medical systems rely on having trusted medical records and security logs record system access requests in order to trace malicious attempts. Keeping multiple copies helps to achieve availability and reliability against such hackers. Unfortunately, maintaining redundant copies in a distributed manner in a byzantine setting has always been a challenging task, however it has recently become simpler given advances in blockchain technologies. In this work, we present a tamper-resistant log system through the use of a blockchain. We leverage the immutable write action and distributed storage provided by the blockchain as a basis to develop a secure log system, but we also add a privacy preserving layer that is essential for many applications. We detail the security and privacy aspects of our solution, as well as how they relate to performance needs in relevant settings. Finally, we implement our system over Hyperledger Fabric and demonstrate the system’s value for several use cases. In addition, we provide a scalability analysis for applying our solution in a large-scale system.
