Blockchain-Based Solution for the Traceability of Spare Parts in Manufacturing

Abstract

Spare parts are essential assets to maintain productivity and operations. A spare part is used for the repair or replacement of failed units. Tracing and tracking of spare parts ownership can help to ensure reliable outcomes in terms of manufacturing operations and service delivery. However, today's spare part inventory systems fall short of providing reliable tracing and tracking of spare parts ownership which poses serious threats to their authenticity. Also, current approaches and systems leveraged for spare part inventory management are vulnerable to the single point of failures. In this paper, we propose a blockchain-based smart contract to trace and track the spare parts ownership details from the original equipment manufacturer to the supplier and end-users. We exploit blockchain features to build a secure and trusted spare part inventory system that is tamper-proof, traceable, trackable, accessible immutable, resilient, and reliable. The proposed system integrates decentralized storage of interplanetary file systems (IPFS) to store and share spare parts data. We present algorithms along with their full implementation details. We perform testing and validation of the smart contract. Furthermore, we provide security and cost analysis, and show how the proposed system ensures reliable tracing and tracking of spare parts ownership. We make the smart contract source code publicly available on Github.

Blockchain and smart contract for IoT enabled smart agriculture

“…File loss rate in currently available cloud storage architectures can be up to 100%, where it is nearly 0% in the blockchain ( Li, Wu & Chen, 2018 ). Decentralized storage (blockchain) of Interplanetary file system to store and share industrial spare parts data has been implemented by Hasan et al (2020) . Blockchain is one of the most secure ways of dealing with electronic transactions.…”

“…The automation includes the real-time tracing of products in a supply chain and overall control over all the steps involved. Hasan et al (2020) integrates smart contracts in their industrial spare parts traceability research work to implement the necessary function, modifiers, and events inside their proposed system, which mainly controls the logical flows that automate the process by using the smart contract.…”

A Blockchain Based Solution for Medication Anti-Counterfeiting and Traceability

“…The application of blockchain in traceability begins with the traceability of supply chain products (see, for example, [18] [19] [20]). These studies have effectively verified that blockchain technology can address the main shortcomings of traditional traceability architecture and solutions.…”

“…In addition, the storage and traceability of medicine information, as well as the authorization of user rights are mostly realized by writing smart contract code. However, there are some security vulnerabilities in a smart contract, such as external call error, malicious database, timestamp dependence, etc [18]. These unknown vulnerabilities will let hackers attack and compromise transactions.…”
