A supply chain (SC) involves many stakeholders, directly or indirectly, for satisfying consumers’ requirements. SC management is restricted by a lack of information sharing among stakeholders as parties of SC do not have direct communication and/or are not willing to share private and competitively sensitive information. In the SC, the bullwhip effect (BWE) is an undesirable phenomenon that aggravates the SC performance and increases the overall cost of SC. The main culprit of BWE is the lack of SC coordination among the parties, which results from wrong and lack of information sharing. Blockchain technology (BT) has the main characteristic of distributed shared ledger that makes all parties in the SC network able to access data. This paper aims to develop a BT model and implement it into the SC.

A blockchain is developed consisting four SC stakeholders and an integrated development environment has been used for coding in Python.

The analysis of the impact of the adoption of BT in SC shows the reduction in BWE.

In SC, BT can be considered as an effective tool to share the demand data among all SC partners. Sharing of such data will improve SC planning and reduce the BWE.

Adoption of blockchain technology (BT) leads to shrinking supply chains, produces a better quality product, saves product development time and increases the customized offering to the customer. Since it is a new and growing area of research, researchers and practitioners are not entirely aware of challenges in the adoption of BT in supply chain (SC). Therefore, the objective of this research is to provide an overview of BT in SC and modeling of challenges in the adoption of BT in SC.

Interpretive structural modeling (ISM) is used to model the challenges of adoption of BT in SC. Challenges are identified by the literature review and verified by expert's opinions.

This study presents some key challenges, i.e. to develop trust within SC management system, obey the governance rules and regulations of institution while implementation of BT in SC, provide transparency of data, obtain tamperproof data to avoid fraud, improve coordination and information sharing among the SC partners, choose a profit-earning product SC for adoption of BT, adopt societal changes and train the participants to strengthen behavioral intention towards adoption of BT in SC. Additionally, interrelationships among the challenges have been identified. This work discusses potential implications based on challenges and provides a platform for the adoption of BT in SC.

The interrelations of the challenges will provide valuable understandings for developing BT solutions in SC to the practitioners.

Blockchain technology (BT) is setting world-shattering standard in all type of transactions in business. BT has the prospective to drastically transform supply chain (SC). The main challenge is to enhance trust among the SC stakeholders. This paper aims to identify and prioritize the factors and its challenges that influence the adoptability of BT in SC. The prioritization of these factors will be helpful to the practitioners to decide the strategy of implementing the BT in SC.

The factors influencing adoption of BT are identified from the review of literature and expert opinion is used to rank the factors influencing the adoptability of BT in SC using grey relational analysis (GRA).

We identified and prioritized key factors: inter-organizational trust and relational governance as organizational challenge, data transparency and data immutability as technological challenge, interoperability and product type as operational challenge and social influence and behavioral intention as social challenge that influences adoptability of BT in SC.

The priority of these factors will guide future researchers and industry practitioners to plan rational and financial strategy for implementing BT in SC.

In the era of digitization, blockchain technology (BCT) has gained huge attraction in a variety of business processes including operations and supply chains (SC) of different industrial sectors. This paper aims that the adoption of BCT in SC enables the industries to integrate the stakeholders and its distinct features enhance the performance of SC.

An attempt is made to develop a BCT platform a pilot case of bearing-SC and identify the challenges and their solutions in the integration of BCT with SC. Moreover, the impact of BCT on measures of SC performance is also studied.

The results show enhanced transparency in the transactions, better security of the data, diminished latency period for transfer of information, improved traceability of the bearing, reduced time for payment transfer process and decreased nonvalue-added activities. Ultimately, overall trust of the customer can be improved by the integration of BCT in bearing-SC.

In the same way, BCT can be applied to SC of other components to assure the product quality to the end-users.
