High-performance blockchain system for fast certification of manufacturing data

Abstract

Integration of blockchain systems into industrial applications show promise in increasing security, trust, and transparency along the value-chain during product and process tracking. However, current solutions suffer performance deficiencies, or often disregard legacy devices still in operation. We propose a blockchain system built upon an IoT architecture that is secure, modular, easily scalable, and deployable for fast certification of manufacturing data, compatible with current industrial landscapes. First, the proposed architecture is presented along with elements required to manage network functions. Second, easing integration with existing manufacturing solutions, custom APIs are created and subsequently explained. This grants the platform plug-and-play capabilities, requiring minimal hardware and software configuration for deployment. Lastly, a prototype is designed to validate the solution, concluding the viability of the proposed architecture as a fast and secure certification method of manufacturing data.

Scalability Solutions in Blockchain-Supported Manufacturing: A Survey

“…The currency can serve as a voucher (namely an Ethereum Request for Comment (ERC) token without smart contracts), and its value can be mapped to FIAT at a fixed price. PoA consensus mechanism was also selected in the case of the proposed architecture for fast certification of manufacturing data, compatible with current industrial landscapes [76]. A general-purpose PoA consensus mechanism is employed due to the permissioned nature of the certification system.…”

“…The open question thus remains with all the proposed concepts of how increased scalability of the system affects decentralization and security [67]. Does this scalable solution change decentralization and security in such a way that such an approach would no longer guarantee trust in the system [76]? In the literature at the moment, no work has yet addressed how the Scalability trilemma of blockchain technology is reflected in the behavior of the users.…”
