Abstract

Explosion-proof apparatus is a must in hazardous areas especially in an industrial setting where certification is required to meet certain safety levels. Conventional certification mechanisms tend to be slow, non-transparent and vulnerable to forgery of documents and delays, particularly in the context of cross border transactions. This article presents the architecture of a blockchain-based certification platform, which could contribute to transparency, traceability, and efficiency in the certification lifecycle of explosion-proof equipment. It includes Ethereum smart contracts, IPFS (InterPlanetary File System) to store the comprehensive test reports on a decentralized platform, and a role-based web application interface for different kinds of users such as manufacturers, testing labs, certification bodies, and field auditors. Smart contracts are responsible for generating, revoking and handling certificate access control, all certification metadata and file hashes are suitably safeguarded on the blockchain, allowing records to remain tamper-proof and verifiable. A working prototype was implemented in Goerli Ethereum testnet and developed as React application. js frontend, Web3. js, IPFS and MetaMask for identity control. Performance testing indicated an average certificate issuance time of 4.8 seconds, verification time of less than 2 seconds, and transaction fee of 0.0004 ETH per operation. As opposed to traditional flows, which take 2–4 weeks to certify, the proposed platform achieves certification in less than a day with full traceability and instant global verification. This paper shows that blockchain technology can help to modernize certification system of industrial safety equipment, providing a secure and scalable solution for traditional certification, and has large potential for future industrial safety application.
