Blockchain Technology for Supply Chains operating in emerging markets: an empirical examination of technology-organization-environment (TOE) framework

Organizations adopt blockchain technologies to provide solutions that deliver transparency, traceability, trust, and security to their stakeholders. In a novel contribution to the literature, this study adopts the technology-organization-environment (TOE) framework to examine the technological, organizational, and environmental dimensions for adopting blockchain technology in supply chains. This represents a departure from prior studies which have adopted the technology acceptance model (TAM), technology readiness index (TRI), theory of planned behavior (TPB), united theory of acceptance and use of technology (UTAUT) models. Data was collected through a survey of 525 supply chain management professionals in India. The research model was tested using structural equation modeling. The results show that all the eleven TOE constructs, including relative advantage, trust, compatibility, security, firm’s IT resources, higher authority support, firm size, monetary resources, rivalry pressure, business partner pressure, and regulatory pressure, had a significant influence on the decision of blockchain technology adoption in Indian supply chains. The findings of this study reveal that the role of blockchain technology adoption in supply chains may significantly improve firm performance improving transparency, trust and security for stakeholders within the supply chain. Further, this research framework contributes to the theoretical advancement of the existing body of knowledge in blockchain technology adoption studies.

istrative costs (Kamble et al., 2019). Blockchain technology (BT) is a powerful tool to transform supply chain operations (Banerjee, 2018;Kshetri, 2018). The adoption of blockchain technology in supply chain operations may affect relative advantage, complexity, upper management support, cost, market dynamics, competitive pressure, and regulatory approval . The primary objective of any supply chain is to focus on cost, quality, speed, flexibility, and risk reduction (Kshetri, 2018). Several organizations are showing interest in adopting blockchain technology in their supply chain operations as it encourages collaboration and reduces trust issues in supply chain operations (Aslam et al., 2021;Lim et al., 2021;Longo et al., 2019).
SCM includes the flow from raw materials manufacturing to the distribution of goods to the consumers. The transactions in the flow need to be recorded and shared with all the players involved in the SC's process to enable transparency in the system. Blockchain technology (BT) can help manage these transactions, enabling collaboration within the players, effective inventory management, and better utilization of available resources (Francisco & Swanson, 2018;Saberi et al., 2019;Tian, 2017;Gökalp et al., 2020a). Hence, adopting blockchain technology can help firms reduce overall logistics and operation costs (Francisco & Swanson, 2018). BT can also help disperse risk for firms. At present, SCM systems tend to be centralized. A centralized SCM system has several drawbacks (Monfared, 2016). For example, centralized systems may be more susceptible to being hacked, or damaged leaving firms vulnerable to having data stolen Hijazi et al., 2019;Mao et al., 2018;Dong et al., 2017). Blockchain technology reduces this risk.
According to PricewaterhouseCoopers (PwC) 'Time for Trust' report released in October 2020 suggests that BT provides solutions by furnishing information on provenance, traceability and tracking ($41 billion) in India in 2030. The draft paper on "Blockchain: The India strategy" released in January 2020 by NITI Aayog, India's think tank on public policy making, stated that Blockchain technology (BT) reduces operational costs by delivering less government and more governance (NITI Aayog draft paper, January 2020). BT has therefore been identified as a disruptive technology.
Prior studies have discussed the challenges and benefits of BT within SCM (Queiroz & Fosso Wamba, 2019a); however, few studies exist which examine user acceptance of BT based SCM (Francisco & Swanson, 2018;Imeri & Khadraoui 2018;Sharma et al., 2020). (Gökalp et al., 2020a) utilized the technology-organization-environment perspective with a sample of 30 experts living in the UK and Turkey. (Kamble et al., 2019) also developed a model to understand the user perceptions of BT in supply chains based on three adoption theories TAM, TRI and TPB. However, research examining blockchain technology in supply chain management integration is still in an emerging phase (Babich & Hilary, 2020;Clohessy et al., 2019;Mathivathanan et al., 2021;Queiroz & Fosso Wamba, 2019a). Therefore, there is an opportunity to conduct further research that employs the TOE model and assesses the relative role of the TOE factors (Kouhizadeh et al., 2021). This study addresses the following research questions: RQ1: What is the influence of technological, organizational, and environmental (TOE) factors on Blockchain technology adoption (BTA) within the supply chain management context? RQ2: Which TOE factors are more strongly associated with blockchain technology adoption (BTA)?
This study employed structural equation modelling-SEM (Arbuckle and Wothke, 1999). SEM combines confirmatory factor analysis and path analysis (Anderson and Gerbing, 1998). CFA was used to assess the measurement of the latent psychological constructs (Garver and Mentzer, 1999). The structural (causal) relationships between the latent constructs were then examined (Anderson and Gerbing, 1998). The findings of this study will help industry decision-makers to understand various TOE factors that are influencing the adoption process. The results will also support the development of an effective implementation plan.
The remainder of this paper progresses as follows: the literature review is presented next, followed by the theoretical framework and hypothesis development. The following section is research methodology followed by data analysis, followed by discussion and the last section is the conclusion.

Blockchain Technology Adoption (BTA) in Supply Chain Management (SCM)
Blockchain technology (BT) was introduced in a white paper on Bitcoin in the cryptocurrency market as a disrupting technology to process and verify data transactions based on a distributed peer to peer network (Nakamoto, 2008). BT can create value for businesses as the 'internet of value' replaces the 'internet of information' (Schlecht et al., 2021). BT has been identified as enhancing supply chain performance as it delivers real-time information sharing, transparency, reliability, cyber security, traceability, and visibility (Sunny et al., 2020;Aslam et al., 2021). BT helps integrate various SC functions such as recording, tracking, data sharing, and scalability (Helo & Hao, 2019;Perboli et al., 2018;Schmidt & Wagner, 2019). In addition, blockchain technology adoption (BTA) provides authentic information to all its stakeholders in the network resulting in immutability, security and subsequently increased client satisfaction (Risius & Spohrer, 2017;Wang et al., 2019). This is important since SCM firms expect reliable data (Korpela et al., 2017). BT, therefore, can enhance visibility and business process management in supply chains (Dutta et al., 2020;Dinh et al., 2018). Table 1 summarises the literature on adopting blockchain technology in supply chains.

Theoretical framework
Several theoretical frameworks have been utilized to examine the adoption of new technologies, including the technology acceptance model (TAM) (Davis, 1989;Davis et al., 1989), the theory of planned behavior (TPB) (Ajzen, 1991), the unified theory of acceptance, the use of technology model (UTAUT) (Venkatesh et al., 2003) and the theory of reasoned action (TRA) (Ajzen & Fishbein, 1975). However, rational choice models are often criticized for being practical, technologically deterministic and techno-centric in their predictions resulting in the technology, as opposed to the users and firms determining adoption. This study adopts the technology, organisation and environment model (TOE) proposed by DePietro et al., (1990) as a way to explore firm choice in embracing innovations. The TOE framework has been identified as the model which delivers a more holistic assessment of the factors determining adoption. It has also been identified as an effective model to examine the value creation and innovation acceptance (Gangwar et al., 2015;Senyo et al., 2016). The TOE framework is also argued to provide higher quality insights based on firms' outer and inner dynamics (Tornatzky et al., 1990). It has been widely applied to existing innovations such Author The objective of the study Findings (Aslam et al., 2021)

Factors impacting BT adoption in oil industry
This study helps in guiding the decision-makers and managers for evaluating the current SC process and also helps to understand the benefits of BT adoption for improving efficiency.  Factors impacting BT adoption in Malaysian SMEs This study surveyed 194 Malaysian SMEs and TOE framework was utilized for identifying the factors for research model. The findings stated that the identified factors will have an impact on BTA in SMEs. (Kamble et al., 2019) To provide a comprehensive understanding of the various decision-making factors that influence the behavioural intention of adopting BT in supply chains.
This study conducted in India with a sample size of 181 supply chain professionals representing 102 companies. The model is developed based on TAM, TRI and TPB. This study found that BT adoption in supply chains may improve the supply chain effectiveess.  To examine the antecedents of blockchain adoption, and its influence on supply chain transparency and blockchain transparency and supply chain performance.
Using data from USA and Indian companies, this study found that the knowledge sharing and trading partner pressure play an important role in blockchain adoption, and supply chain performance is significantly influenced by supply chain transparency and blockchain transparency. (Gokalp et al., 2019a) Factors impacting BT adoption TOE framework was utilized to propose the research model. AHP method was used for ranking the identified factors and sub-factors. The number of respondents were 30. The findings stated that environment perspective are more important than organizational and technological perspectives. (Kshetri, 2018) Role of BT in fulfilling critical objectives of SCM SCM objectives like flexibility, risk reduction, sustainability, quality, dependability, and speed were considered. DOI theory had been utilized in the study which stated that the firms who are trading with many layers of suppliers will be benefitted using the BTA.  (Hsu & Yeh, 2017), cloud computing (CC) (Gangwar et al., 2015), and RFID (Wang et al., 2010). Therefore, there is an opportunity to expand the application of the TOE framework to BTA within SCM. Table 2 outlines the TOE dimensions employed in this study (Fig. 1).

Hypotheses development
The current study develops a model which identifies the various components of technology, organizational, and environmental perspectives for BTA within SCM. Thus, the model enables an exploration of technology development, organizational conditions, configuration, and the industry environment when assessing the adoption and use of BTM in SCM.

Technological Perspective
The technological dimension of the TOE model refers to the pool of internal and external technologies to the firm and their perceived usefulness, compatibility, complexity, and usage. The TP dimension provides an opportunity to examine the extraneous and in-house technologies that influence BT's adoption in SCM of a firm. It considers the selection and decision making concerning the adoption of software, networks, hardware and how they are adjusted in a compelling way to accomplish the accepted procedures of BTA (Aslam et al., 2021). To date, there has been limited research on the technological attribute for adopting BT in SCM. As such, we identify the TP dimension in BT as including Relative advantage (RA), Trust (T), Compatibility (COM) and Scalability (SC). 2.3.1.1 Relative advantage (RA) RA refers to the enhancement of performance and productivity of SCM by BTA. As per (Tipmontian et al., 2020, BT improves SCM efficiency, product process, and quality. This technology offers better transparency with the process of SCM (Francisco & Swanson, 2018;Gokalp et al., 2019;Helo & Hao, 2019;Risius & Spohrer, 2017;Saberi et al., 2019;. RA can be defined as a determinant impacting a firms' adoption of BT in SCM. Therefore, We propose that: H1: Relative advantage has a significant positive effect on blockchain technology adoption (BTA) in SCM.

Fig. 1 Proposed research TOE framework for blockchain technology adoption
2.3.1.2 Trust (T) Trust is defined as the cost-benefit trade-off concerning the risks related to technological adoption (Nam et al., 2020). Prior research suggests that components like security and privacy do not affect BT as they are its main features Alsetoohy et al., 2019a;Francisco & Swanson, 2018b;Isma'ili et al., 2016;Makena, 2013;Nuskiya, 2017;Shee et al., 2018). However, trust has been a significant contributor to TA (Kamble et al., 2019). Hence, it is considered an essential latent variable in the current study. We, therefore, posit that: H2: Trust has a significant positive effect on blockchain technology adoption (BTA) in SCM.
2.3.1.3 Compatibility (COM) Compatibility relates to the ability for the new technology to integrate with the adopter's previous practices, existing qualities and present needs (Rogers, 1995). Compatibility is higher for new technologies where they are compatible with existing IT resources. As COM has been considered a significant determinant within SCM systems (Dutta et al., 2020;Koh et al., 2020;Sheel & Nath, 2019;Tan et al., 2018;Verhoeven et al., 2018;. We, therefore, identify it as a latent variable impacting firms' adoption of BT in SCM as we propose that: H3: Compatibility has a significant positive effect on blockchain technology adoption (BTA) in SCM.
2.3.1.4 Security (SC) Security in the blockchain is a comprehensive plan for managing the risk in the blockchain networks to avoid the dangers of online attacks or fraud by ensuring trust in transactions. It works on the principles of cryptography, decentralization, and consensus. In supply chains, product information security can be improved using blockchain technology (Behnke & Janssen, 2020). BT extension and the cost involved in its extension is considered a complex and complicated task (Wang et al., 2016). Additional computational power for validating, processing and storing data is required. Increased BT size can slow transaction efficiency (Makhdoom et al., 2019). Hence, SC has been considered an indicator in the current study for BTA in SCM. We propose that: H4: Security has a significant positive effect on blockchain technology adoption (BTA) in SCM.

Organizational perspective (OP)
The organisational perspective of the TOE framework refers to the resources and internal characteristics of the firm (Gide & Sandu, 2015), including intangible and tangible resources. Prior studies (Alsetoohy et al., 2019b;Damanpour, 2016;Gutierrez et al., 2015;Moch & Morse, 1977;Senyo et al., 2016b) have identified various components which are inclusive of OP. For this study, these are identified as the firms' IT resources (FITR), higher authority support (HAS), firm size (FS), and monetary resources (MR).

Firm's IT resources (FITR) FITR refers to how the firms' technical infrastruc-
ture displays readiness to adopt the new technology within the existing system. In BT, a duplicate copy of the transaction is stored in the IT storage system to efficiently support a database query and enable traceability of a product or service (Francisco & Swanson, 2018). Human resources play an essential role in BTA readiness given the requirement for advanced IT skills and technologically sound infrastructure (Grublješič & Jaklič, 2015). We, therefore, consider FITR as an important latent variable in the current study. Hence, the proposed hypothesis is: H5: The firm's IT resources positively affect blockchain technology adoption (BTA) in SCM.
2.3.2.2 Higher authority support (HAS) Higher authority support (HAS) has a significant role in accepting and implementing new technologies in a firm. HAS individuals, if aware of the benefits of BTA in SCM, can support the transition to the latest technology by creating a positive climate within the firm (Alsetoohy et al., 2019;Dutta et al., 2020;Isma'ili et al., 2016;Makena, 2013;Nam et al., 2020). Given that BTA requires allocating human and financial resources, integrating BT with existing IT infrastructures, and BPR in client and supplier relationship management , HAS is essential to adoption success. We posit that: H6: Higher authority support significantly affects blockchain technology adoption (BTA) in SCM.

Firm size (FS)
As the firm's size increases, the capability of risk handling and paybacks also develops. Prior studies Low et al., 2011;Makena & Kenyatta 2013;Oliveira & Martins, n.d.;Tornatzky & Klein 1982) have identified FS as an essential factor for the adoption of innovations. Hence, larger firms are more interested in adopting new and advanced technologies than smaller firms (Senyo et al., 2016). (Pan & Jang, 2008;Zhu et al., 2011) have stated that larger firms have better readiness in adopting innovations as they are better able to adjust to risk than smaller firms. Hence, FS is considered a latent variable in the current study. We propose that: H7: Firm size has a significant positive effect on blockchain technology adoption (BTA) in SCM.

Monetary resources (MR) When a higher monetary amount is allocated in a firm
to initiate and maintain changes technologically, it helps build a competitive advantage in the market for a longer time (Clohessy et al., 2019;Kumar & Krishnamoorthy, 2020;Maroufkhani et al., 2020). MR are critical to successful adoption, especially in BT (Al-Hujran et al., 2018;Amini & Bakri, 2015;Mrhaouarh et al., 2018). Hence, MR has been considered a latent variable in the current study. Therefore, the proposed hypothesis is: H8: Monetary resources positively affect SCM's blockchain technology adoption (BTA).

Environmental perspective (EP)
EP refers to impacts arising from external sources of the firm. Various indicators have been identified in the study which relates to the EP factor, including rivalry pressure (RP), business partners pressure (BPP) and regulatory support (RS). 2.3.3.1 Rivalry pressure (RP) RP refers to the competition the firms face from other competitive firms within the same industry (Gokalp et al., 2019;Tashkandi & Al-Jabri, 2015). RP is an essential factor impacting new technology adoption as per prior studies (Francisco & Swanson, 2018;Saberi et al., 2019;Dutta et al., 2020;Kamble et al., 2019). BT offers more transparency and efficiency in SCM. Hence, RP has been considered a latent variable in the current study. We propose that: H9: Rivalry Pressure positively affects SCM blockchain technology adoption (BTA). 2.3.3.2 Business partners' pressure (BPP) BPP refers to the pressure faced by firms from its business partners (Alharbi et al., 2016) and has a critical impact on advanced technology adoption (Alsetoohy et al., 2019a;Shee et al., 2018). Business partner collaboration is essential for maintaining trade relations, primarily where a dominant partner exists in the SC. BPP has been a critical factor in BTA in SCM in prior studies (Braunscheidel & Suresh, 2009;Francisco & Swanson, 2018;Saberi et al., 2019). Hence, we posit that: H10: Business Partners' Pressure positively affects the blockchain technology adoption (BTA) in SCM. 2.3.3.3 Regulatory Support (RS) RS refers to the regulations and policies set by Government for monitoring and regulating industries for new technology usage. This is a fundamental factor impacting innovation diffusion. As BT is an emerging technology, regulations such as authority for digitalized records and access rights have not yet been established (Korpela et al., 2017.;Sharma et al., 2020). As a result, RS has been defined as a determinant impacting firms' BTA in SCM. We propose that: H11: Regulatory Support has a significant effect on blockchain technology adoption (BTA) in SCM.

Data and sample
An online survey was used to collect the data (Lefever et al., 2007). The respondent's indystry details were found on the company websites. This study selected only the supply chain professionals or the employees working in the supply chain department. The criteria for determining the respondents were based on educational qualification and experience in the field of supply chain and IT. The email id was obtained from the company websites or after contacting the HR department. An email regarding the consent for the study was emailed to the 1075 targeted respondents. A total of 525 supply chain professionals agreed to participate in the survey. Before sending the questionnaire to all the respondents, a pilot survey was carried out by sending 55 questionnaires to the supply chain professionals. The questionnaire was then sent to 525 supply chain professionals working in different industries such as healthcare, manufacturing, retail, textile, and food. Three hundred and fifteen responses from the supply chain professionals were received, indicating an acceptable response rate of 60% (Moss & Hendry, 2002). After the data cleaning process a total of two hundred eightyseven responses were available for use in the final analysis. The companies selected for this study were listed on the national stock exchange and were limited to India. To preserve the anonymity of the participants, we have used a random sampling method.

Research instrument development
Scales were adapted from prior studies (Churchill et al., 1974;Nunnally, 1978). A 7-point Likert scale on an interval range from 'strongly disagree' to 'strongly agree' was developed for this study for measuring the items, as shown in Table 3. Six experienced academicians who were subject experts verified the questionnaire.

Common Method Bias (CMB)
CMB was assessed via Harman's single factor test. Exploratory factor analysis was performed, and the results show that the first factor explained a maximum covariance of (15.209%), which is below the recommended value of 50% (Podsakoff et al., 2003).

Data Analysis
A four-step method was adopted to test the hypothesis and model. Firstly, reliability and validity were measured, followed by exploratory factor analysis (EFA) using SPSS 20.0. The measurement model was developed, and convergent validity, composite reliability, and discriminant validity were examined before the structural model was tested using AMOS 22.0.

Reliability and validity (Cronbach's alpha)
Assessment of reliability helps examine the degree of internal consistency between variable measurement items and its freedom of error at any point in time (Kline, 2015). Cronbach's alpha is used to measure the reliability of the data (Hair et al., 2014). The values should be greater than 0.70, i.e., the recommended level (Nunnally, 1994). Table 4 shows Cronbach's alpha values for all the items.

Exploratory factor analysis
The Kaiser-Meyer-Olkin (KMO) was calculated at 0.802, greater than the 0.60 minimum level (Hair et al., 2012). All the factor loading values were greater than 0.5, the acceptance level (Hair et al., 2010). Table 5 shows the factor loading for the rotated component matrix.

Measurement model
The values of composite reliability and AVE are presented in Table 6. From (Hooper, 2008) FITR2: The human resources of the organization must be knowledgeable enough in order to adopt the change. FITR3: There is a need to have good internet connectivity for the better utilization of IT resources. FITR4: It will help in improving the efficiency of the system. Higher Authority Support HAS1: It is fundamental for embracing blockchain technology in our firm.
(Yap et al., 2017) HAS2: The choice to receive administrations in our association relies upon more significant position authority. HAS3: It is important for top administration to be engaged with dynamics according to blockchain technology. HAS4: It is fundamental for the higher authority to be associated with inspecting a specialist's blockchain technological suggestions. HAS5: Higher official's role is critical in adopting this latest technology. HAS6: As a decision maker I will prefer blockchain technology in my firm. the AVE values are above the recommended value of 0.50 and satisfy the convergent validity (Fornell & Larcker, 1981).
Construct pairs were assessed and found to achieve discriminant validity (Fornell & Larcker, 1981) stringent tests. The results are presented in Table 7. The table shows that the square root of AVE shown bold is higher than the correlation between the constructs, indicating that all the constructs in Table 7 satisfied the discriminant validity and can be used to test the structural model.
Confirmatory factor analysis was performed. As indicated in Table 8, the model fit the data well. The χ2/df ratio value was 1.889, which is lower than the threshold value of 3 as suggested by (Byrne, 2010). The goodness of fit statistics indicated a good model fit.  (To & Ngai, 2006) RP2: It provide better services in the firm efficiency. RP3: It provides better understanding of market competitiveness. RP4: It helps in maintaining the authority in data sharing process. Business Partners Pressure BPP1: I would utilize blockchain technology to improve coordination among the business partners. (Lin & Lin, 2008;Makena, 2013) BPP2: Our firm's business partners are recommending this blockchain technology adoption. BPP3: Blockchain technology adoption will increase the trust of the business partners for us. BPP4: Business partners of our firms are against this blockchain technology adoption. BPP5: Our business partners support the decision taken by the firm. BPP6: Our business partners do not support the decision taken by the firm. Regulatory Support RS1: I would utilize blockchain technology on the off chance that they consented to our guidelines. (Alain & Ooi, 2008) I would utilize blockchain technology in the event that they agreed with our mechanical guidelines. The laws and guidelines that exist these days are not adequate to ensure data put away in the virtual storage. It is vital that virtual resources' guidelines conform to law in India.

Structural model
The blockchain technology adoption (BTA) model is shown in Fig. 2. The structural model has 11 unobserved latent factors and forty-seven observed variables. These 47 indicators act as the indicators of their respective underlying latent constructs. SEM was conducted using AMOS 22.0.
The researchers tested the hypotheses by conducting structural equation modelling (SEM) using AMOS 22.0, as shown in Fig. 2. It can be observed from Table 9 that all the constructs are found to be significant and support the hypotheses. The goodness of fit indices as reported in Table 10 was χ2 = 2658.439 with df = 1314, RMSEA = 0.054, IFI = 0.903, CFI = 0.911, TLI = 0.904, and GFI = 0.953, which were within the threshold values suggested by (Hu et al., 2009). For all the constructs in our model, the fit indices are acceptable. The  results of the hypotheses are shown in Table 9. The acceptable model with standardised coefficients for the paths is shown in Fig. 2. We can infer from Table 9 that all the eleven study variables tested relationships in the final SEM model were statistically significant.
The findings further report that the independent constructs explained 42% of the variance in blockchain technology adoption.

Discussion
The current study empirically examined the adoption of blockchain technology in the supply chain management of various firms. Prior studies were reviewed and proposed a model based on the TOE frameworkwas presented. Eleven hypotheses were submitted for testing the model, and all were significant. The technological perspective comprises four factors: relative advantage, trust, compatibility, and security. The first hypothesis examined the impact of relative advantage on blockchain technology adoption in supply chain management. The importance of relative advantage on blockchain technology adoption in supply chain management was supported (β = 0.181, p = .000). Relative advantage is a critical component in prior IT-related studies (Alharbi et al., 2016;Alkhater et al., 2018;Amini & Bakri, 2015;Gangwar et al., 2014;Ghode et al., 2020;Gokalp et al., 2019), the adoption of cloud computing for healthcare organisations (Alharbi et al., 2016) and supply chain management among Malaysian SMEs .
The second hypothesis examined the impact of trust on blockchain technology adoption in supply chain management. Trust had a positive relationship with blockchain technology (β = 0.245, p = .000). Trust is a significant contributor in prior studies Alazab et al., 2021;Alkhater et al., 2018;Francisco & Swanson, 2018;.
The third hypothesis examined the impact of compatibility on blockchain technology adoption in supply chain management. Compatibility was found to have a moderate effect on blockchain technology adoption in supply chain management (β = 0.211, p = .000). Compatibility is a critical component in prior studies Alharbi et al., 2016;Alkhater et al., 2018;Amini & Bakri, 2015;Kumar & Krishnamoorthy, 2020;Makena, 2013) and particularly the adoption of cloud computing. However, it is non-significant in the manufacturing sector (Oliveira et al., 2014).  The fourth hypothesis examined the impact of security on blockchain technology adoption in supply chain management. The relationship between security and blockchain technology adoption in supply chain management was supported (β = 0.263, p = .000). This is in line with previous studies, which have found that security is a critical component in prior studies (Alkhater et al., 2018;Mrhaouarh et al., 2018;. The organizational perspective consists of four factors: firm's IT resources, higher authority support, firm size, and monetary resources. The fifth hypothesis examined the impact of a firm's IT resources on blockchain technology adoption in supply chain management. A firm's IT resources are an essential determinant of adoption (Gokalp et al., 2019).
In the current study, the firm's IT resources were positively related to blockchain technology adoption (β = 0.277, p = .000).
The sixth hypothesis examined the impact of higher authority support on blockchain technology adoption in supply chain management, and the relationship was supported (β = 0.412, p = .000) in the current study. Upper management support has been essential blockchain adoption in Malaysian SMEs' operations and supply chain management .
The seventh hypothesis examined the impact of firm size on blockchain technology adoption in supply chain management. Firm size was supported as a moderate driver of adoption intis the study (β = 0.394, p = .000), supporting prior research which has found that size is a critical factor in the adoption of technology Clohessy et al., 2019;Gide & Sandu, 2015;Lin, 2014;Makena, 2013;Nuskiya, 2017;Skafi et al., 2020).
The eighth hypothesis examined the impact of monetary resources on blockchain technology adoption in supply chain management. Economic resources have been a critical component (Nam et al., 2020). Also, in the final structural model, the current study supported the financial resources and blockchain technology adoption in supply chain management (β = 0.321, p = .000). The environmental perspective consisted of three factors: rivalry pressure, business partners' pressure, and regulatory support; all the three factors displayed positive relationships with adoption. Rivalry pressure has been a critical component in prior studies (Amini & Bakri, 2015;Gangwar et al., 2014;Kumar & Krishnamoorthy, 2020;Lin, 2014;Maroufkhani et al., 2020;Mrhaouarh et al., 2018). Competitive pressure has been found to influence blockchain adoption in operations and supply chain management among   Malaysian SMEs (Wong et al., 2020a). The ninth hypothesis, which examined the impact of rivalry pressure on blockchain technology adoption in supply chain management, was supported (β = 0.371, p = .000) in the current study.
The tenth hypothesis examined the impact of business partners' pressure on blockchain technology adoption in supply chain management. Business partners' pressure has been a critical component in prior studies Alharbi et al., 2016;Cruz-Jesus et al., 2019;Gokalp et al., 2019;Haryanto et al., 2020;Kouhizadeh et al., 2021;Lin 2014;Senyo et al., 2016;Sharma et al., 2020;Wong et al., 2020a). Trading partners pressure has been linked to blockchain adoption in both the USA and India . This study supports prior research findings as BPP had a moderate impact upon adoption (β = 0.293, p = .000).
The final hypothesis examined the impact of regulatory support on blockchain technology adoption in supply chain management. In line with prior research, regulatory support was also identified as an essential driver of adoption (β = 0.343, p = .000) Amini & Bakri, 2015;Gide & Sandu, 2015;Gokalp et al., 2019;Maroufkhani et al., 2020;Oliveira et al., 2014;Senyo et al., 2016). This represents a departure from the findings of (Wong et al., 2020a), who found that regulatory support was not significant in blockchain adoption in operations and supply chain management among Malaysian SMEs.

Managerial implications
This study will assist management in understanding, managing, and coordinating blockchain technology adoption in supply chains. The sample was drawn from a diverse range of industries, including healthcare, manufacturing, retail, textile, and food. This study found that higher authority support is critical for adopting emerging technologies such as blockchain technology in the supply chains. Top management should be aware of the benefits of implementing the latest technologies to support organisational transformation by eliminating resistance to change from the existing systems and assisting operations to function efficiently and effectively. Therefore, it is recommended that top management support and encourage staff to adopt the new technologies that allow flexibility and innovation. This can be achieved by creating a positive and supportive organisational culture, including fostering trust in the latest technology, which will support adoption.
Firm size, the second significant factor in this study, implies that as the company's size increases, the ability to handle risks also increases. According to (MendlingJan et al., 2018), firm size is essential for adopting blockchain technologies. Hence, it is advised that larger organizations should consider the adoption of innovative technologies to gain a competitive advantage in the market. Rivalry pressure has been found to significantly impact the technology adoption process in the prior literature (Francisco & Swanson, 2018c;Gokalp et al., 2019).
In addition, this study also found that the firm's IT resources have a direct influence on blockchain technology adoption. The extent to which firms are ready to adopt new innovative technologies within the existing infrastructure is necessary to support firm success. BT needs to be seamlessly integrated with existing resources. If the organisation and its staff perceive BT as compatible, they will be more likely to approach adoption. A positive organisational perspective on BT may also be created to develop a comprehensive plan for managing risk. This will assist the organisation in avoiding the dangers of online attacks or fraud by ensuring trust in transactions as it works on the principles of cryptography, decentralization, and consensus. Business partners should also have an integrated approach to adopting new technologies to increase operational efficiency within the supply chains among all the stakeholders. Relative advantage, was found to play an essential role in enhancing productivity and performance with the adoption of BT. Organisations will therefore benefit from the adoption of BT through improved operational efficiency in the overall supply chain.

Conclusions
This study provides fruitful insights and empirical evidence for various firms to remove barriers and challenges for adopting blockchain technologyPrior research on BT has been criticized, including a small sample-sized limited industry analysis (Gökalp et al., 2020). This study provides robust insights into the adoption of BT by utilising a large sample size of respondents' across multiple industry sectors. The responses for the current study are collected from various Indian industries like healthcare, manufacturing, retail, textile, and food increasing the generalisability of the identified factors within both diverse and developing countries. In addition, this research has established the validity of the relationships between constructs by employing a structural modeling approach. This empirical approach supports management decision making concerning the adoption of blockchain within organizations whilst also providing evidence-based approaches to enhance the efficiency of the firm.

Limitations and future research
There are certain limitations for the study, leading to future research in this area. In this study, we have compared responses given by various industries. Future studies may focus on a single sector to ascertain context specificity. Also, further research should examine the model within developing countries to understand the implications of this research.
