ARCHITECTURE FOR A BLOCKCHAIN-BASED CERTIFICATION PLATFORM FOR EXPLOSION-PROOF DEVICES

Abstract

Explosion-proof apparatus is a must in hazardous areas especially in anindustrial 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 Architecture for a Blockchain-based Certification Platform for Explosion-Proof Devices https://iaeme.com/Home/journal/IJCET499
