5.1 CONCLUDING REMARKS
In this study, the current state of blockchain-based supply chain management systems is examined, and an improved framework is proposed. The proposed framework enhances trust by ensuring product data anchored to the blockchain is trustworthy and is verifiable leveraging on digital product certificate embedded with a digital signature of an authorized certification body and smart contract for ensuring correctness and authenticity. Complete product history traceability is also captured not only for participants in the blockchain network but also the end consumer. It can therefore be concluded that blockchain indeed has the potential to revolutionize and disrupt the logistics and supply chain operations in the industry. However, a deeper understanding of the technology is required by managers, organizations, and all key leaders in the industry.
A common misconception discovered based on the research is the direct use of blockchain as a trusted agent in supply chain due to the inherent consensus mechanism implemented for securing and validating transactions, especially in the financial sector. Blockchain application in the financial sector enjoys trust as an inherent property largely because financial assets are digital. However, this inherent transactional trust does not directly transfer into supply chain management sector because the technology operates alongside a moving physical asset. Therefore, a critical analysis of the processes and operations in the supply chain management sector is required to tailor blockchain applications to make a good fit for the supply chain industry.
In conclusion, the adoption of blockchain in the supply chain industry will positively impact the supply chain industry and bring many benefits and efficiency in the operation of supply chain management transactions granted product data anchored into the blockchain are authentic and verifiable by all parties involved.
