Project Title: A Study On Blockchain Technology And Its Applications In Selected Areas Of Service Sector

A Final year project on “A Study On Blockchain Technology And Its Applications In Selected Areas Of Service Sector” was submitted by Athira Venugopal (from PSG Institute of Management and Technology Coimbatore, Tamil Nadu, Anna University )to extrudesign.com.

1. ABSTRACT

While blockchain technology is commonly considered potentially disruptive in various regards, there is a lack of understanding where and how blockchain technology is effectively applicable and where it has mentionable practical effects. This issue has given rise to critical voices that judge the technology as over-hyped. Against this backdrop, this study adopts an established research framework to structure the insights of the current body of research on blockchain technology, outline the present research scope as well as disregarded topics, and sketch out multidisciplinary research approaches. The framework differentiates three groups of activities (design and features, measurement and value, management and organization) at four levels of analysis (healthcare sector, manufacturing industry, and finance sector).

Keywords: Blockchain, Digitisation, service sector, healthcare, finance, Manufacturing, Supply chain.

2. INTRODUCTION TO BLOCKCHAIN TECHNOLOGY

2.1 Background

A blockchain is a computerized, open record that records online exchanges. Blockchain is the center of innovation for cryptographic forms of money like bitcoin. A blockchain guarantees the honesty of a digital currency by encoding, approving, and for all time recording exchanges. A blockchain is like a bank’s record, yet open and available to everybody who uses the digital currency is underpins. The convention for blockchains permits numerous gatherings that don’t have the foggiest idea or trust each other to keep up an agreement with regards to the condition of and changes made to a common database. Consider it like Wikipedia which is composed and kept up by a few creators and editors. Bitcoin has utilized blockchain innovation to empower installment exchanges between outsiders without the requirement for an outsider budgetary middle person (i.e., a bank). Members in blockchain can make “permissioned blockchains”— that is, those that are secretly kept up by a little gathering, here, the banks (Zuberi, 2017).

It can be defined as a computerized, open record that records online exchanges. Blockchain is the center of innovation for cryptographic forms of money like bitcoin. A blockchain guarantees the honesty of a digital currency by encoding, approving, and for all time recording exchanges. A blockchain is like a bank’s record, yet open and available to everybody who uses the digital currency is underpins.

Blockchain innovation right now gets a great deal of open consideration as supporters contend that it comprises the establishment for genuinely sans trust financial exchanges dependent on its one-of-a-kind mechanical qualities (Glaser 2017). Blockchain innovation is among the most slanting advances (Gartner 2016) and contended to disturb different middle-person administrations (Tapscott and Tapscott 2016). It procured acclaim as the innovation hidden Bitcoin (Beck and Muller-Bloch 2017) yet is at present extended to different territories of utilization (Wou¨rner et al. 2016). Simultaneously, be that as it may, researchers are drawing matches between blockchain innovations and, for instance, bubble memory in regards to their progressive effect on business, recollecting that bubble memory additionally never satisfied the hopes related with it (Avital et al. 2016). Glaser (2017) rehashes the regularly communicated worry that blockchain innovation is an imaginative innovation looking for use cases. Notwithstanding the extraordinary desires, there is as of now a lack of information concerning where and how blockchain innovation is successfully appropriate and where it can give mentionable cultural impacts. We contend that examination can help conquer this scarcity by extensively understanding the impacts of one-of-a-kind blockchain properties (e.g., decentralization, transaction speed, security, adaptability, and control) and by exploring individually fitting cultural fields of utilization. Up until this point, in any case, application-situated commitments to blockchain inquire about to give off an impression of being rare, detached, and concentrated on a predetermined number of subjects (e.g., installment frameworks). To address these issues, we draw on a setup inquire about a system that has recently helped structure and make an important research stream in the related zone of online life and business change (Aral et al. 2013). We adjust this structure to the particularities of blockchain innovation. By drawing on a productively settled structure and moving the relating research questions, we mean to efficiently sort out findings and create explore themes that look past the present thought about subjects.

Along these lines, two research questions are addressed: What is the flow condition of information concerning blockchain, and in what capacity can it deliberately be progressed? To accomplish the exploration objective, I have efficiently gathered distributed insightful blockchain papers to survey the viability of the related research structure and important mechanical establishments (Tschorsch and Scheuermann 2016). Rather than existing blockchain structures (Yli-Huumo et al. 2016), this methodology empowers the structure flow findings just as move inquire about inquiries past the focal point of surviving work. Pushing ahead from the ebb and flow condition of research, this feature connects to different trains and proposes beginning stages for observational research by pointing at some accessible information sources that can help close the enormous inconsistency between academic information and desires. The blockchain is a moderate innovation used to confirm and store exchange records for online digital forms of money like Bitcoin. The framework is repetitive and disseminated, making it hard for exchanges to be revoked, copied, or faked. In past online monetary forms, the blockchain has potential uses in medicinal services, instruction, and numerous different fields. This section will quickly portray what the blockchain is and how it is being utilized, potential future uses that might be of interest to participants of the service sector.

2.2 Evolution

The thought behind blockchain innovation was portrayed as ahead of schedule as in 1991 when examining researchers Stuart Haber and W. Scott Stornetta presented a computationally down-to-earth answer for time-stepping advanced reports so they couldn’t be predated or altered.

The framework utilized a cryptographically tied down chain of squares to store the time-stepped archives and in 1992 Merkle trees were consolidated to the structure, making it progressively proficient by permitting a few records to be gathered into one square. In any case, this innovation went unused and the patent slipped by in 2004, four years before the commencement of Bitcoin.

Satoshi Nakamoto is licensed as the cerebrum behind blockchain innovation. Next to no is referred to about Nakamoto as individuals accept he could be an individual or a gathering of individuals that chipped away at Bitcoin, the principal utilization of the computerized record innovation.

Nakamoto conceptualized the first blockchain in 2008 from where the innovation has advanced and discovered its way into numerous applications past digital forms of money. Satoshi Nakamotodischarged the first whitepaper about the innovation in 2009. In the whitepaper, he gave subtleties of how the innovation was well prepared to improve advanced trust given the decentralization angle that implied no one could ever be in charge of anything.

Blockchain is the spine of Technology of Digital Crypto Currency Bit-Coin. The blockchain is an appropriate database of records of all things considered or computerized occasions that has been executed and shared among taking an interested party. Every exchange is confirmed by most of the members of the framework. It contains every record of every exchange. Bit-Coin is the most well-known digital money case of the blockchain. Blockchain Technology previously became exposed when an individual or group of people name ‘Satoshi Nakamoto’ distributed a white paper on “BitCoin: A shared electronic money framework” in 2008. Blockchain Technology Records Transaction in Digital Ledger which is disseminated over the Network in this way making it morally sound. Anything of significant worth like Land Assets, Cars, and so on can be recorded on Blockchain as a Transaction.

2.3 Blockchain and Its Features

Organizations in various ventures are investigating and testing better approaches to:

• Execute exchanges speedier for an improved client assistance,
• Ensure cost effectiveness in its activities
• Assure straightforwardness to clients and controllers.

With immense volumes of information getting produced each day attributable to the digitization of records, it gets significant for each association to adequately deal with the security dangers and accomplish huge cost efficiencies.

This is the place Blockchain, with its guarantees of decentralized possession, permanence and cryptographic security of information are grabbing the eye of the C-suite administrators. Different use cases are additionally getting investigated across ventures as everybody has begun understanding the problematic capability of this innovation.

The changelessness of a Blockchain causes it about outlandish for changes to be made once settled, which expands trust in information respectability and diminishes open doors for extortion. The unchanging nature and irreversibility highlight of a Blockchain originates from the hidden information structure which is known as a Merkle tree or Hash tree.

2.4 Types of Blockchain Systems

There are a few different ways to assemble a blockchain arrangement. They can be open, private, permissioned, or worked by a consortium.

Open blockchain systems :

An open blockchain is one that anybody can join and take part in, for example, Bitcoin. Downsides may incorporate significant computational force required, almost no protection for exchanges, and frail security. These are significant contemplations for big business use instances of blockchain.

Private blockchain systems :

A private blockchain arrange as an open blockchain arrange, is a decentralized shared system, with the noteworthy distinction that one association administers the system. That association controls who is permitted to take part in the system, execute an agreement convention and keep up the mutual record. Contingent upon the utilization case, this can altogether support trust and certainty between members. A private blockchain can be run behind a corporate firewall and even be facilitated on-premises.

Permissioned blockchain systems :

Organizations that set up a private blockchain, will commonly set up a permissioned blockchain arrangement. Note that open blockchain systems can likewise be permissioned. This spots limitations on who is permitted to take an interest in the system, and just in specific exchanges. Members need to get a greeting or authorization to join.

Consortium blockchains :

Various associations can share the obligations of keeping up a blockchain. These pre-chosen associations figure out who may submit exchanges or access the information. A consortium blockchain is perfect for business when all members should be permissioned and have a mutual duty regarding the blockchain.

2.5 How Blockchain Technology Functions?

One of the popular utilization of Blockchain is Bitcoin. Bitcoin is cryptographic money and is utilized to trade advanced resources on the web. Bitcoin utilizes cryptographic verification rather than outsider trust for two gatherings to execute exchanges over the web. Every exchange secures through a computerized signature.

A blockchain is, in the least difficult of terms, a period stepped arrangement of changeless records of information that is overseen by a group of PCs not possessed by any single element. Every one of these squares of information is verified and bound to one another utilizing cryptographic standards.

The blockchain organize has no focal position — it is the very meaning of a democratized framework. Since it is a mutual and unchanging record, the data in it is open for anybody and everybody to see. Subsequently, anything that is based on the blockchain is by its very nature straightforward and everybody included is responsible for their activities.

Dispersed Database, There is no Central Server or System which keeps the information of Blockchain. The information is conveyed more than Millions of Computers around the globe which are associated with the Blockchain. This framework permits the Notarization of Data as it is available on each Node and is freely unquestionable.

A hub is a PC associated with the Blockchain Network. Hub gets associated with Blockchain utilizing the customer. The customer helps in approving and

proliferating exchange onto the Blockchain. At the point when PC associates with the Blockchain, a duplicate of the Blockchain information gets downloaded into the framework and the hub comes in a state of harmony with the most recent square of information on Blockchain. The Node associated with the Blockchain which helps in the execution of a Transaction as a result of a motivator is called Miners.

Most blockchains—and Bitcoin is the greatest—are what you call consent-less frameworks. We can do exchanges and fulfill each other’s monetary needs without knowing who the other party is and free from focal specialists. These blockchains all have computerized money or some likeness thereof connected with them, which is the reason everyone discusses Bitcoin in a similar breath as the blockchain because the Bitcoin blockchain is the greatest.

In any case, the blockchain, a hidden innovation, is the greatest advancement in software engineering—the possibility of a dispersed database where trust is built up through mass coordinated effort and smart code as opposed to through an incredible establishment that does the validation and the settlement.

2.6 Drawbacks of Current Blockchain Framework

• Money must be utilized in low sum exchange locally.
• Tremendous holding up time in the preparing of exchanges.
• Need to outsider for check and execution of Transaction make the procedure complex.
• In the event that the Central Server like Banks is undermined, entire System is influenced including the members.
• Association doing approval charge high procedure in this manner making the procedure costly.

2.7 Advantages of Blockchain Technology

• Efficient: No focal Authority check required for settlements making the procedure quicker and less expensive.
• Cost-sparing: A Blockchain organize decreases costs in a few different ways. No requirement for outsider confirmation. Members can share resources legitimately. Middle people are diminished. Exchange endeavors are limited as each member has a duplicate of shared record.
• More tightly security: No one can temper with Blockchain Data as it shared among a large number of Participant. The framework is sheltered against cybercrimes and Fraud.

2.8 Blockchain Technology: Indian scenario

Even though Blockchain Technology in India is still in its early stage, it can acquire an immense distinction in how the nation runs once it gets consolidated. India is a rising force, and exploiting the chances of this new Internet can acquire the nation the Radar of improvement. The nation has an excessive number of issues to be dealt with—all in the areas vital for an economy to flourish, for example, administration, money-related administrations, farming, social insurance, land, and moreover. Blockchain can illuminate them as well as include a Midas’touch!

Perhaps the most grounded advantage of Blockchain Technology in India is its potential for information assurance. With the huge development in information, particularly in Government workplaces, comes the dangers of Cyber assaults and, thus, defilement. Other than this, an adjustment in votes to pick up the larger part; illicit migration; undeclared salary, and property are a portion of the dangers that have spread their underlying foundations complicatedly in the framework. Appropriation of a superior and methodical methodology, as Blockchain Technology, can be the response to all these.

The nation is gaining significant quick ground as far as blockchain instruction. As per a market examination by Dappros (a London-based blockchain counseling firm), India remains in the second situation in the check of Blockchain Developers (with almost 19,627 engineers), second to the US with 44,979 Blockchain Developers, on the planet. This may have given you an unpleasant thought of where blockchain training in India stands today.

2.9 Research Gap Identification

Blockchain is an innovation is a forthcoming innovation. It may be the case that it won’t turn out as significant as now proselytized. It is fascinating to visit this theme, later on, to perceive how the movement has been made and approve the necessities.

Blockchain plans of action and applications could be one intriguing wellspring of data that could be utilized to test the recommendations set forward. The application structure can be planned by including more territories of uses would give some measurement to discoveries of this work.

Blockchain as an innovation is an up-and-coming innovation. It may be the case that it won’t turn out as significant as now proselytized. It is intriguing to visit this theme, later on, to perceive how the movement has been made and approve the necessities. Blockchain plans of action and applications could be one fascinating wellspring of data that could be utilized to test the proposals set forward. The application system can be structured by including more zones of uses would give some measurement to discoveries of this work. Blockchain innovation offers such a model. Blockchains break with a large number of the defective suspicions of conventional system security. Together, these properties permit framework fashioners to re-examine the basic designs of digital frameworks and systems.

It ought to be noticed that for the structure idea delineated right now, are a few holes are recognized as follows:

There is scope in the territories for structuring Framework for Blockchain dependent on explicit Use Cases. Be that as it may, there is no current research in the zone of Blockchain structures dependent on the source, needs of an association characterized by the Trust Requirements of Information Sharing. Blockchain innovation is a foundational exchange advancement in data preparation. Blockchain empowers trust-dependent exchanges between parties that were already incapable to confide in one another by methods for a permanent exchange sign in review trail and check of request and legitimacy of exchanges, in addition to other things. (Rajala, 2016)

2.10 Objectives

• To study the functions and types of block chain
• To study possible applications of blockchain technology in service sector.
• To identify the process, scope and significance of Blockchain technology.
• To find possible future special technological changes in finance, manufacturing and healthcaresectors.

3. REVIEW OF LITERATURE:

3.1 Theoretical Framework

Definitions of Blockchain Technology

As its name proposes, a blockchain is comprised of a progression of “obstructs.” Blockchain programming records every exchange in a square without the guide of an outsider like a bank or installment processor. The blockchain calculation naturally encodes and validates the exchange, which is quickly noticeable to all clients, limiting the chance of extortion. The conditions of the exchange do exclude any close to home or distinguishing data.

Blockchain innovation was designed to administer bitcoin, the first and most well-known cryptographic money. Some more up-to-date stages, like ethereum, utilize a blockchain to give an advanced biological system to dispersed processing, viably utilizing digital money to oil the works. In ethereum, squares run what’s known as a keen agreement to guarantee that specific conditions are met before assistance is rendered.

Each blockchain client has a similar duplicate of the whole blockchain as every other person. This makes it difficult to control: a programmer would need to tackle registering power more prominent than that of each client to modify the blockchain in support of her. On account of this ironclad security, significant standard organizations like Citigroup and the London Stock Exchange have grasped blockchain innovation, in the desire for utilizing it, for instance, to ensure licensed innovation or store venture records. Blockchains may even be utilized by specialists and performers to verify their work and get reasonable remuneration from fans. It may not be well before craftsmen forego permitting their work to a distributor, who takes a cut when they can enlist it straightforwardly to a blockchain. Banks have been delayed to receive the blockchain. Meanwhile, Bankrate can assist you with picking the correct bank to store your cash.

A blockchain comprises of computerized record of exchanges. The name originates from its structure, wherein singular records, called squares, are connected in a single rundown, called a chain. Blockchains are utilized for recording exchanges made with cryptographic forms of money, for example, Bitcoin, and have numerous different applications.

Every exchange added to a blockchain is approved by different PCs on the Internet. These frameworks, which are arranged to screen explicit sorts of blockchain exchanges, structure a shared system. They cooperate to guarantee every exchange is substantial before it is added to the blockchain. This decentralized system of PCs guarantees a solitary framework can’t add invalid squares to the chain.

At the point when another square is added to a blockchain, it is connected to the past square utilizing a cryptographic hash created from the substance of the past square. This guarantees the chain is rarely broken and that each square is for all time recorded. It is additionally purposefully hard to adjust past exchanges in blockchain since all the resulting squares must be modified first.

Shin, 2019. The societal implications of blockchain technology are immense. Blockchain has provided financial services to a great number of customers without access to banking via online, debit cards, and ATMs. It has additionally allowed micropayments and microloans to people in disadvantaged socio-economic circumstances, unraveling a completely new form of advantage for the world economy.

Park, 2018. Another example of a social implication is within a section of social enterprise where lack of trust is a specific issue. Blockchain technology produces a meaningful means of finding a way around the challenges of corruption. The decentralized characteristics of the blockchain and smart- contracts mean that an agreement built on its platform does not need a separate party. As smart contracts are computer code, contractual conditions could be translated into logical functions which trigger subsequently when set conditions are met.

Marsal-Llacuna, 2018. It is feasible to add clauses in smart agreements which specify that obligations are met if certain results are accomplished. Smart agreements may even be used to govern the circulation of currency. Blockchain continues to gain momentum in a myriad of use cases across a wide variety of industries. Firms are increasing their investments in blockchain to transform how they deliver products and services, gain new insights to obtain a competitive edge, and improve their financial and operational performance.

Macrinici et al., 2018. The fact that blockchain ledger records are secure, sequential, and immutable improves the security of customer information as well as business and transaction records.

Kshetri, 2017. Ironically, such a trust-based mechanism is blockchain’s most vulnerable point. Information and services of blockchains are vulnerable to manipulation by hackers or foreign powers, and personal data are not necessarily private.

Pink et al., 2018. As blockchain develops in different sectors of various domains, security-related issues become prime factors in determining the success of the blockchain economy. Blockchain will continue to change the future of digital transactions in the new data economy and transform the nature of the digital trust).

Filippi and Hassan, 2016. Digital trust in blockchain can be defined as enabling user heuristics made between security and privacy that reflect their level of confidence. Digital trust is a kind of user heuristics in the blockchain. Blockchain users are likely to cope with the perceived risk, security, and privacy, and overload by using heuristics that minimize their cognitive effort and time, through the use of cognitive heuristics.

Shin and Park, 2019. Digital trust as cognitive heuristics constitute information processing methods to make decisions more quickly and with less effort than more complex methods, and thus they reduce cognitive load during a security assessment.

3.2 Hypothetical Framework

This study is a combined result of blockchain technological applications in three sectors mainly: finance, manufacturing, and health care. The data is collected from existing studies specializing in each sector, through systematic mapping.

In the financial industry, blockchain innovation remains at an enunciation point. Regularly mistaken for bitcoin, blockchains are the underpinnings of Bitcoin. In particular, the blockchain is a database or a record that keeps up a constantly developing rundown of information records or exchanges. Blockchain’s problematic nature is gotten from its capacity to change practically any procedure, from fundamental documentation to settling complex agreements. Built-up monetary foundations are becoming keen on the blockchain’s potential for bank-to-bank moves, and many accept that the best open doors around blockchain originate from the computerization of wasteful back-office format budgetary establishments (Zuberi, 2017). Blockchain innovation remains at an enunciation point. Regularly mistaken for Bitcoin, blockchains are the underpinnings of Bitcoin. In particular, the blockchain is a database or a record that keeps up a constantly developing rundown of information records or exchanges. Blockchain’s problematic nature is gotten from its capacity to change practically any procedure, from fundamental documentation to settling complex agreements. Built-up monetary foundations are becoming keen on the blockchain’s potential for bank-to-bank moves, and many accept that the best open doors around blockchain originate from the computerization of wasteful back-office forms at budgetary establishments (Albekov Adam Umarovich, 2017). While matters including advanced resources may appear to be outside the course of everyday business, cryptographic money is a subject worth comprehension at an essential level. Admittedly, the eventual fate of cryptographic forms of money is obscure. Their supporting innovation is transformative and advancing; it seems ready to make its engraving upon the universe of business. Extra administrative and authoritative commands relating to blockchain and digital forms of money are not out of the ordinary. Those guidelines will, without a doubt, affect IM practice. Businessworks on a not so much substantial but rather more computerized premise as time passes. This pattern is exemplified by the approach of driverless vehicles, the universality of the cloud, the prevalence of online administrations, and the extension of the Internet of Things to working environments, homes, and (even) bodies, using advanced medication ( Nancy Dupre Barnes,2018). Tolerating new advancements is in this manner urgent to the achievement of any industry in the fourth modern unrest. Advancements, for example, Social Media, Mobile, Analytics (and Big Data), Cloud, alongside the Internet of Things (SMACT/SMACIT), have become unavoidable computerized disruptors that have essentially changed the plans of action and offers of firms across ventures. The monetary administrations part has been upset by advancements, for example, M-Pesa, SnapScan, and EcoCash, which have made it progressively comprehensive (Kinyanjui Mungai et al, 2017). It has been proved that virtual currencies are a new kind of electronic money stored in computer memory, the monetary value of the virtual currency is managed using a technical device. Virtual currency is a new means of payment and does not require access to deposit accounts (Elena Anatolyevna et al, 2018).

A common misconception in the marketplace is that blockchain technology is finance, financial reporting, or otherwise accounting-oriented tool or platform, but this only represents a partial view of the functionality embedded in this technology. Rather, blockchain can be more accurately thought of as a database structure, akin to Excel or Access, with several additional attributes that differentiate it from existing technology options (Adams and Sumutka, 2018). Business visionaries can likewise raise capital from retail financial specialists who don’t qualify as certified speculators by method for crowdfunding.

Historically, with striking similitude to ICOs offering “utility tokens,” crowdfunding was advanced by web stages, for example, Kickstarter as a way to sidestep the protection laws with returns conveyed to speculators in resources or different prizes, free T-shirts. Utilizing the qualification among customers and financial specialists dependent on buyer inspiration permits the backer to sidestep protections laws, as shoppers are simply ensured per their legally binding rights, while speculators appreciate broad insurance of protections laws and the SEC. Crowdfunding was supported as an exception to the protection laws dependent on the potential insurance offered by the “‘shrewdness’ of the group,” as crowdfunding stages take into consideration open conversation among guarantors and speculators, a deliberative procedure of correspondence which is viewed as a substitute to administrative checking (Shlomit Azgad, 2018).

Besides its vast opportunities in the finance sector, blockchain technology has contributed largely to the manufacturing and health care industries. The managerial decision-making process is directly dependent on the efficiency of information flow in the company (Golinska, et. al., 2015). An Analysis of the information flow efficiency in the intermodal supply chain – research results Adam Kolinski, Ewa Jaskolska effectively-prepared information flow is aimed at supporting the decision-making process, which will directly affect the quickness and accuracy of the decisions being made, both in economic and ecological terms (Sliwczynski & Kolinski, 2016). The globalization of the trade

and services market has made it necessary to focus on the key processes performed by individual enterprises in the supply chain. For this reason, logistics operators have started to play an important role in the service market. Operators, using their resources, experience, and skills, guarantee to their business partners the highest level of realization of logistic processes. One of the key elements for improving logistics processes efficiency through the use of Fourth Party Logistics is the information flow integration (Agata Horzela et al, 2018). The decision-making process depends on up-to-date and accurate data. This makes the efficient information flow in both the enterprise and the supply chain a key aspect of decision-making. The selection of IT tools supporting management and decision-making has a direct impact on the efficiency of information flow in the enterprise and supply chain. (Adam Kolinski et al, 2018). These benefits are driven by the ability for the right people to have access to the right information at the right time, with the technology delivering that information. (Nina Evans et al, 2018). From a cognitive perspective, one would have expected that large firms would have had difficulties in considering and evaluating new and in certain cases still unrelated products, services, or technologies (Tripsas and Gavetti, 2000; Gilbert, 2006). Instead, we find that the studied companies had little problem in overcoming path dependencies associated with prior experiences and knowledge. In the current state, supply chains are dependent on systems such as enterprise resource planning (ERP) that stores all the information at one central place for most of the time. This ERP or allied systems have their shortcomings. Moreover, the lack of trust among the supply chain members complicates things even further. Single point failure is another shortcoming of this centralized system making it susceptible to attack, corruption, and hacking (Dong et al., 2017). However, It is interesting to note that in the decentralized ledger system, users can be anonymous (public network) or visible (private network, say a supply chain network). The public and private networks have one key difference and that is access to the ledger. In a public network, each user has a copy of the ledger and participates in the conforming transactions independently whereas, in the case of a private network, participants require permission to keep the copy of the ledger and participate in the confirming transactions. (Gurudutt Nayak et al, 2019). In BT, an agent

makes a new transaction that is to be included in the blockchain. The new transaction is broadcast to all the members for verification. When the majority of the members or nodes approve the new transaction, it is added as a new block. This approval is based on some pre-specified rules (Smart contract) and cannot be changed without the consent of all people in the network. The smart contract, one of the key features of BT, empowers the agents to conduct an authenticated transaction without the involvement of any third party. A smart contract is naturally a software program that supplies rules and policies for negotiating terms and actions among agents. It automatically authenticates whether the contractual terms are met and accomplishes various transactions (Delmolino, Arnett, Kosba, Miller, & Shi, 2016). Moreover, BT guarantees transparency without causing any behavioral changes among the participant agents, thereby leading to greater trust in the overall network. This is the key driving factor for improving supply chain performance. How BT will change SCM is uncertain and needs further research (Saberi, Kouhizadeh, et al., 2018) attention. BT will be very effective for designing, organizing, and planning the general management and operations of supply chains. According to Baker and Steiner (2015), four new entities namely, registrars, standards organizations, certifiers, and actors will play major roles in SSCM using BT.

The supply chain is defined as “a set of three or more entities (organizations or individuals) directly involved in the upstream and downstream progression of items, administrations, funds, or potentially data from a source to a customer” (Mentzer et al., 2001, p.4).On a conceptual level, supply chain management (SCM) is nothing yet dealing with these streams to make an incentive for the collaborating firms and a definitive client. (Mentzer et al., 2001, p. 18) in their fundamental paper characterize SCM as “the foundational, key coordination of the traditional business functions and the tactics across these business functions within a particular company and across businesses within the supply chain, to improve the long-term performance of the individual companies and the supply chain as a whole”.SCM is one of the core value-adding activities of the business, which has stood out among industry professionals and researchers. SCM writing is improved with inquiring about strings, for example, production network incorporation (Flynn, Huo, and Zhao,2010;

Gunasekaran and Ngai, 2004), inventory network coordination light-footed store network, supply chain execution design of supply chain. The increasing trend on sustainability has shifted attention to SSCM.

SSCM can be characterized as “the administration of material, data and capital streams just as a collaboration among organizations along with the store network while coordinating objectives from every one of the three measurements of sustainable development, i.e., economic, environmental and social, which are derived from customer and partner necessities. In manageable stock chains, natural and social criteria should be satisfied by the individuals to stay inside the inventory network, while it is normal that seriousness would be maintained through meeting customer needs and related economic criteria” (Seuring &Müller, 2008, p.1700). SSCM is a critical junction on which merges the triple-bottom-line namely, environmental, social, and financial execution (Golicic and Smith, 2013). Scholarly discussion on SSCM is restricted and in this way, the subject requires further research consideration. Scientists have investigated SSCM  unmistakably in an assembling setting contrasted with the administration’s field (Hassini, Surti, and Searcy, 2012). Nourishment-based and vehicle-based SSCM are generally investigated in detail. SSCMwriting has been widely considered utilizing an interdisciplinary and blend strategy approach, for instance, contextual analyses, applied/hypothetical displaying, review-based, and meet-based ( Dubeyet al., 2017, Svensson,2007) studies. The impact of SSCM on supply chain performance shows mixed results. One strand of literature argues that SSCM leads to economic gains as it increases energy efficiency, enhances goodwill and brand value, results in cost-cutting, etc. (Ageron, Gunasekaran, & Spalanzani, 2012). However, another strand of literature opines that SSCM is difficult to structure and execute and it makes critical weight on the inventory network individuals to modify their behavior,leadingtonotsopositiveimpactsontheoverallsupplychaininSME (Pagell&Shevchenko, 2014; Zhu, Sarkis, and Lai,2007). The multifaceted nature of SCM is a step by step expanding and factors, for example, globalization, digital assaults, artful conduct of accomplices are making SSCM execution in SMEs even more difficult.

In healthcare, blockchain is a distributed digital ledger in which records are kept by many instead of one. This shared ledger is decentralized, meaning it does not rely on a central point of control. In general blockchain applications, this makes it possible to manage transactions accurately without the need for third parties, such as banks or regulatory agencies. Blockchain technology can be used for authentication and verification of data for a wide range of applications ranging from patient-centric access control of health data to image sharing to enhanced cyber security (V. Patel, 2019). Verified data can be securely shared at the patient’s discretion, including a ledger of important clinical information, such as contrast allergy information and presence or lack of metal in the body. If this information was secured on a patient’s blockchain health record, knowledge transfer would be more seamless across institutions.

Here the author has highlighted the importance of healthcare and wellbeing for all age groups by quoting the third goal of DGSs. They further emphasized that inclusive healthcare is possible by effective, efficient, and holistic monitoring covering all aspects of the healthcare domain. The exponential rise of wearable healthcare devices is changing the ways, the vitals of the patients are being monitored. The emergence of non-invasive technologies has further added to the development. The authors studied the effect and usability of wearable healthcare devices in terms of “intrusiveness”, “Comfort”, “perceived usefulness” and perceived “ease of use”. They used the “Partial Least Square Structured Equation Modeling (PLS-SEM)” methodology to find the relation between concept and hypothesis. They concluded that intrusiveness and comfort do not play a major role in the adoption of wearable devices however the potential usefulness and ease-of-use are the prime factors of adopting wearable healthcare devices on such a large scale (Papa Armando, et al, 2018). Here the provided a survey on the role of IoT in achieving smart healthcare. They discussed the core technologies, issues, and challenges of IoT in achieving smart healthcare. They concluded that standardization of data constitutes the primary challenge in the IoT ecosystem. Finally, some future directions of applications of IoT in the healthcare domain were highlighted (Baker SB et al, 2018).

5. FINDINGS AND DISCUSSION

5.1 Importance of Blockchain Technology

Security purposes

The computerized world is loaded up with programmers hoping to rupture data or take information from sources. With blockchain innovation, the data put away has strong security making it inconceivable for one to hack.

Transparency

Since everything is shown on the system, there are fewer possibilities that there would be any sort of error that can be made.

It is modest

A large portion of the conventional money-related models that are accessible in the market are costly, nonetheless, with blockchain it is modest.

Less exchange time

An individual can send, get cash and money-related records within two or three minutes, this lessens the weight of hanging tight for quite a long time together.

Financial productivity is expanded

Decentralized blockchain permits one to make exchanges from individual to individual without the inclusion of the outsider. This assistance sets aside a ton of cash while making exchanges, in contrast to conventional banks.

Protect organizations from misrepresentation

The blockchain is open-source records which is the reason it is anything but difficult to recognize if misrepresentation has occurred since each exchange is recorded on them.

5.2 Scope of Blockchain Technology

• Blockchain in Digital Advertising: Presently, advanced publicizing faces a ton of difficulties like space misrepresentation, bot traffic, absence of straightforwardness and long installment models, because of the issue like motivating forces are not associated. Due to this the advertisers and distributers feel they are dropping the arrangement. Blockchain has given an answer for convey straightforwardness to the store network as it brings trust in a trustless situation. Blockchain permits right organizations to succeed, by diminishing the quantity of terrible players in the inventory network. Distributers can likewise accumulate a tremendous level of theall- out notice dollars showing up the environment. The Blockchain innovation is still in its start; be that as it may, this innovation should remain here, and all ad organizations are seeing that how blockchain will assist with improving their business.
• Blockchain in Cyber Security: Though the blockchain is an open record, the information is confirmed and encoded utilizing creative cryptography innovation. Right now, data or information is less inclined to be assaulted or modified without approval.
• Blockchain will expel the prerequisite of the outsider: With the assistance of Blockchain innovation, fundamentally, it is conceivable to affect a shifted scope of procedures and methods. It disposes of the need of confided in outsider in the exchanges. Well most noticeable associations on the planet exist today to work as a confided in outsider, for example, SWIFT, and the Depository Trust Cleaning Company.Corporate chances prosper for organizations that can fabricate applied Blockchain advancements focusing on specific exchanges, similar to the home loan industry. The current home loans required a convoluted trap of title look, title protection, and uncountable minor exchange expenses which are required to keep the framework running. These frameworks happen in light of the fact that customarily, the exchange of land has been a procedure which requires a lot of confidence in the old records. The Blockchain innovation was going to address every one of these worries, and a specific property’s record comprises of an evident and approved exchanges history, bringing down the need of organizations to give chanceadjustment and trust administrations.
• Governments will give their computerized monetary standards: It is affirmed that the paper cash at its last stage, however it is additionally discovered that the approved money is confronting a serious challenge by digital currencies. In 2017, it is seen that the cost of Bitcoinhas flown which was never observed by any single assistance or cash all around the globe. The money is as yet one of the most refreshing properties accessible in the market, and the country paid heed, because of the cost of Bitcoin is denied by the essential thought of interest and supply. The requirement for Bitcoin will again move eventually, with a fixed breaking point of twenty-one million units of Bitcoin. Along these lines, a couple of governments will get an opportunity to make their computerized monetary standards to abstain from dropping face to an autonomous and unregulated property and take an interest in an open market.
• Blockchain past the universe of processing: In 2017, the world had seen the interminable assortment of choices in the utilization of blockchain innovation. As of now, the vast majority ofthe nations are building up their blockchain methodologies to hold what’s to come. Likewise, it is exceptionally conceivable that the remainder of the propelled European nations will take actionaccordingly by tolerating the blockchain innovation to make a consistent money related condition that helps countries on ruins like Greece and Spain. There are explicit issues related with the security of funds, and Blockchain will be utilized to address these sorts of issues. Blockchain will likewise be utilized to create libraries which are utilized for medicinal purposes, to oversee protection strategies, and to interfere with the model of pointless informationstockpiling.
• Overseeing World exchange with the assistance of Blockchain Technology: Blockchain is significant to business especially how it makes simple for anyone to follow the inventory network of everything gave utilizing the innovation. It will be obsolete to follow the numbers, and no organization needs to lose a shipment in view of human failure. All things considered, itis anything but difficult to enroll a load shipments in the Blockchain, this empowers the gatherings associated with the activity to follow the conveyance methodology from guide A toward B. With the assistance of Blockchain innovation, it is simple for the custom specialists to find the taboo items like phony medications, changed nourishment items, bogus garments multiplication, counterfeit automobile parts, electronic contraption and other robbery operators which are attempting to give the low-quality products inside any nation without discussing the interior laws.
• Inventory network Management: With the assistance of blockchain innovation, it is conceivable to report the exchange in an everlasting disseminated record, and regulate the exchanges all the more sturdily and straightforwardly. This additionally assists with limiting human blunders and time delays. It is additionally utilized screen costs, work, and discharges ateach purpose of the inventory network. Be that as it may, this has extreme impact forcomprehension and observing the real natural effects of items.
• Not just this the decentralized record can likewise be used to check the authenticity or reasonableexchange status of items by tailing them structure their source.
• The Blockchain in Forecasting: The blockchain innovation is set to modify the total philosophyfor look into, counseling, investigation and anticipating. The worldwide conveyed forecast markets are made with the assistance of online stages.
• Utilization of Blockchain in the Internet of Things and Networking: Different organizations like Samsung and IBM are using the blockchain innovation for another idea called ADEPT, this will assist with making a circulated system of IoT gadgets. The blockchain innovation will expel the prerequisite for a focal area to deal with the correspondence between them; this will work as an open record for countless gadgets. The gadgets may speak with one another to overhaul the product, handle the blunders and watch vitality practice.
• Blockchain in distributed storage: The information on a brought together server is presented to hacking, loss of information, or human blunder. With the assistance of blockchain innovation, it is conceivable to make the distributed storage progressively ensured and hearty against hacking.

5.3 Sector wise implications of the research.

5.3.1 Finance Sector

Blockchains are based on a progression of advancements in sorting out and sharing information. The objective for money-related foundations is to manufacture a blockchain with one rendition of reality, utilized by all members, consistently, to at last modernize the back-office. Blockchain technology offers banks richer data; banks with rich data can use it to turn the data into information for corporate clients (Zuberi, 2017). The use of a computer, phone, and access to the internet is expected to improve financial inclusion (Nika Pranata et al, 2019). Information on the accuracy of the monetary contracting (metadata) is generally given by review frameworks, and controlling permits auspicious distinguishing and amending the financial procedures dysfunctions. Anyway, the metadata assortment and handling advances permit making alterations and rely upon middle people (data technologists, faculty of the control and supervision division, and so forth.), which makes the chance of mistaken metadata appearance(Albekov Adam Umarovich, et al,2017). Currently on account of bitcoins, for example, digital currencies can’t scale to the degree of trading Visas for web-based buying. The speed with which electronic buys are finished using Mastercard is unrivaled – and quickness is a fundamental segment of the internet shopping experience. However, expecting the innovations hidden digital currencies proceed to develop and pick up acknowledgment, further refinements could enhance such issues of scale. Many organizations acknowledge and use cryptographic forms of money, including Microsoft and Dell. Until further notice, organizations that acknowledge digital forms of money as installments, people who guess on cryptographic money speculations, and the experts who serve customers taking part in digital money-related exchanges require administrative lucidity and expense exhortation. Numerous money-related affiliations and overseeing bodies, including the U.S. Government Trade Commission, U.S.in 2015 (Nancy Dupre Barnes, 2018). Digitalization promises to transform tax administration more rapidly than it will the tax rules themselves. The point of the paper is to direct exploration of the effect of the blockchain innovation stage on the monetary area through digital money, and its effect on different ventures. The subject of research isn’t just this innovation yet in addition its business abuse. To comprehend the stage, the beginning stage of this exploration is an examination of how the innovation capacities, after that the focal points for business and monetary exchange are distinguished, lastly, the paper manages an effect of the innovation on business, most importantly on budgetary tasks. The essential theory is that blockchain has accomplished an incredible effect on the budgetary area, additionally, it can profoundly change just the monetary segment yet in addition to how we purchase and sell, our association with the specialists as a method for checking the possession from the initiation and the natural nourishment creation. Utilizing the accessible information and amalgamation of information from the fields of innovation, financial aspects, account, and legislative issues, 4 situations were set up for the eventual fate of hidden innovation. The situation approach is joined with pattern examination to demonstrate the beginning speculation with high dependability. The exploration results show that the innovation being researched as of now profoundly affects the budgetary division, that it is in the underlying period of changing numerous enterprises, with the probability that they will transform them all together in the following five to ten years. Organizations progressively find the intensity of this innovation to abuse the advantages of the Fourth Technological Revolution (Dusko Knezevic, 2018). The pattern towards centralization, computerized isolate, absence of straightforwardness in the dynamic procedure, and untouchable intensity of center designers – every one of these variables raises doubt about the populist idea of current circulated systems, making some blockchain supporters’ desires overestimated and unreasonable (Ankur Arora, 2018). The pattern towards centralization, computerized separation, absence of straightforwardness in the dynamic procedure, and untouchable intensity of center designers – every one of these components raises doubt about the libertarian idea of current conveyed systems, making some blockchain supporters’ desires overestimated and ridiculous (Ankur Arora, 2018). Organizations can use blockchains in an assortment of approaches to increase a bit of leeway over their rivals.

They can streamline their center business, decrease exchange expenses, and make licensed innovation proprietorship and installments progressively straightforward and computerized (Felin and Lakhani 2018). Bitcoin or another virtual currency supported by blockchain technology can help businesses to solve funding-related problems. For instance, cryptocurrencies support companies that wish to implement non-cash payments and accounting settlements. The automation of electronic transaction management accounting improves the level of control of monetary business execution, both internally and externally (Zadorozhnyi et al. 2018). In addition, blockchain technology represents an emerging source of venture capital crowdfunding (O’Dair and Owen 2019). Regarding the characteristic of money, cryptocurrency is acceptable. But in terms of the legal perspectives, cryptocurrency does not meet the criteria as currency. From the economic perspective, cryptocurrency does not fully meet the characteristic currency due to high price volatility, and from the Sharia perspective, cryptocurrency can be considered property but not as a monetary value (Mirza Hedismarlina Yuneline, 2018).

5.3.2 Manufacturing Sector

Blockchain innovation has changed pretty much every area of the corporate world. Be it banking, protection, general administration, or advertising, it is proclaimed as the key image of the fourth mechanical upset and one of the greatest disruptors for some enterprises (Calderon et al., 2016). Advanced administration of blockchain can change hierarchical culture as well as increment trust between different partners. The primary target of the investigation was to show how blockchain innovation could be concocted concerning corporate administration (Yermack, 2017). Blockchain is ostensibly the most recent in a long queue of innovations that can be utilized to help e-SCM, and it is critical to set up whether it can satisfy everyone’s expectations and be more compelling than a portion of its forerunners. (Büyüközkan and Göçer, 2018) gave a survey of computerized store network innovation however excluded blockchain from their work consequently showing the absence of scholarly consideration on this significant phenomenon, even in the latest writing. Of the above e-SCM arrangements, blockchain innovation shares ostensibly the most for all intents and purposes with RFID and ERP. RFID has pulled in a ton of examination in the OSCM writing as, like blockchain, it gives a start to finish production network arrangement (Attaran, 2007; Thiesseetal.,2011; Papadopou losetal.,2017) and track and follow abilities. Further, both have been pushed as methods for improving the straightforwardness of supply chains and of tending to issues, for example, item falsifying (for example Staake et al., 2009; Cheung and Choi, 2011). Be that as it may, the effect of RFID on supply chains has, in certain occurrences, been somewhat disappointing, and usage has been difficult. In the interim, the capacity of ERP to give a system arrangement is confined as execution is ordinarily constrained to the limits of the firm. In this way, it is essential to consider how blockchain usage can gain from firms’ past encounters with other e-SCM advances, particularly RFID and ERP. The uncertainty involved in decision-making and partnering between supply chain members can be reduced by building trust because the trusting partner has confidence that the other party can be relied upon (Morgan and Hunt, 1994). Trust also facilitates a greater mutuality in goal setting and tackling issues (Sahay, 2003), such as in the context of sustainability, and trust in supply chain members, as a cooperative governance mechanism, can be utilized to create value (Cuevas et al., 2015). The link between trust and the use of blockchain technology however is not clear and therefore in need of further scrutiny by researchers. One way of thinking is that blockchain expels the requirement for trust from the system because the information can’t be produced. Blockchain has uncertainty been portrayed as a trustless framework (Swan, 2015; Glaser, 2017) because there is no dependence on the reliability of a partner to guarantee the (savy) contract is being met, as innovation is utilized to guarantee this is going on. Blockchain ostensibly empowers the conveyance of trust over the system since it doesn’t require significant levels of confidence in singleauthoritiesasaverified, immutable record of transactions is accessible and represented by the framework itself (Zhu et al., 2019). Previously, it has been accepted that an association’s data gives them a vital upper hand, and firms want to share it unreservedly (Agrawal and Pak, 2001), while blockchain requires information get to or the relationship will not be viable.

One of the most significant parts of blockchain applications is their interface with the physical world, which requires the correct devices and innovation, for example, IoT(Christidis and Devetsikiotis 2016; Catallini 2017). IoT is a term that is utilized to portray interconnected detecting gadgets that can share data on a typical stage, empowering imaginative applications (Gubbi et al. 2013). A portion of the fundamental empowering innovations behind IoT is RFID labels, Wireless Sensor Networks, and information investigation and representation stages (for more data on IoT components see Gubbi et al. 2013). Despite the wide applications of IoT devices in supply chains (Fan et al. 2015; Rong et al. 2015; Ben- Daya, Hassini, and Bahrain 2017), the significant expenses of keeping up brought together IoT frameworks in supply chains (Christidis and Devetsikiotis 2016) and the security concerns encompassing IoT gadgets, for example, RFID-empowered items (Yao et al. 2016) that could without much of a stretch rupture the basic assembling data of supply chains or the individual data of clients, there is an ideal case for the utilization of trustless and P2P blockchain systems. Blockchains help with the availability and limit issues of IoT frameworks by encouraging new gadgets that distinguish and confirm one another so the system can stretch out to billions of gadgets with no mediator servers becoming a bottleneck in the process (Dickson2016). In addition, blockchains are considered to record IoT devices’configurations by putting away their cryptographic hashes (Kumar 2017). A case of the utilization of blockchains for IoT frameworks is conveying messages between gadgets on a blockchain where each message is dealt with also to an exchange (Banafa 2017). Keen agreements are utilized right now to check and permit activities by the gadgets, and any strange message won’t enact the elements of the savvy contract, in this manner expanding the security of the IoT stage. One generally applied part of matching IoT gadgets on blockchain systems is the identification and end of fake medication utilizing a blend of RFID, examination, and blockchains (Mackey and Nayyar 2017).

5.3.3 Healthcare Sector

Blockchain technology in combination with the other modern technologies has the power to transform the existing smart healthcare systems from a centralized and vulnerable system to a distributed, decentralized, and secure system that can help in improving the quality of medical and other related services. The rationale behind considering blockchain as a means to improve the healthcare system is multifold. Firstly, it helps to provide transparent data to all stakeholders while maintaining the privacy of the patients. Secondly, it becomes impossible for the malicious attackers to tamper the valuable medical records and also prevent them from any kind of data theft and eavesdropping. It also puts a check on the expensive manual inefficiencies. Blockchain-based healthcare systems can further provide inexpensive and secure services to insurance companies, drug supply chains, pharmaceutical companies, and medical researchers (Gautami Tripathi et al, 2019). The concept of this system is to ensure that an encrypted procedure has been performed, before connecting to the blockchain infrastructure, to the data of patients caught by sensors connected to the e-Health platform, with the aim that this confidential patient health data may be protected from data theft such as man-in-the-middle attack(Syahril Efendi,2018). Some of the greatest advantages that the application of this technology in healthcare could bring are access to a large pool of anonymized healthcare data that could be used for personalized drug development, rationalization of healthcare and health insurance costs, as well as improvement of public health policies. In addition, private health information could be in patients’ hands, empowering them to be in control of what information institutions receive and keep, under what circumstances, and for how long. Together with data availability about healthcare providers, this type of patient involvement could bring forth a new era in healthcare. (Igor Radanović, 2018). A blockchain solution can lighten this burden on the doctor by creating a higher level of organization, accessibility, and amenability to timesaving digital tools while also further engaging the patient in their care. Currently, information is siloed: transferring records over municipal boundaries can require written requests, and problems with duplication of data, fraud, and inaccessible data are rampant (Mo Tayeb, personal communication, August 25, 2017). The medical chain has introduced a digitized solution that leads doctors through a structured discharge process that reduces errors and omissions and speeds up review by senior staff. The storage and sharing of health information present an enormous challenge, including some important risks to privacy, and fantastic opportunities, including the potential to develop a practical understanding of the health of unique individuals instead of generic humanity. Blockchain technology companies are diving into this space and promising a new era of research and discovery propelled by analysis of aggregated longitudinal health information from individuals in the context of that from the population at large, and by a new ability for researchers to access data they need to gain new insights (Mark A. Engelhardt, 2017). The blockchain carries

cryptographically signed instructions. A cryptographic hash of the records removes any possibility of tampering, thus ensuring data integrity. Thus, data remain secure and immutable.

6. CONCLUSIONS:

Blockchain is the peer-to-peer (P2P) decentralized transaction and publicly available digital ledger. Since 2008 bitcoin and Blockchain are the two most important technologies in an information system. Blockchain can be used in numerous applications to perform a transaction in a trustful environment without a third party. In this survey work, initially explain research method has been discussed followed by the architecture and working principle of the Blockchain. Next twelve applications area where Blockchain technology looks promising to solve the existing centralized system in a decentralized way also several security issues are addressed. Some of the most demanding application areas like the Internet of Things (IoT), Healthcare, etc. have been identified…From the study, it was found that some work is being done in term of privacy and security issues but lots of improvement need to be done. Blockchain technology has numerous advantages like decentralized, publicly available transactions, openness, secure. However, there is still some research need to be done like network, scalability, and mining process of the Blockchain system.

6.1 Finance sector:

The new infrastructure of financial services based on the blockchain will build the processes in a new way and raise doubts about traditional approaches, which are the basis of nowadays’ business models. In those areas where the blockchain application would give maximum effect, deep cooperation between market participants, developers and regulators will be required. Even though the blockchain.

BlockChain and Financial Controlling in the System of Technological Provision of Large Corporations’ Economic Security 10 technology has a great potential to bring simplicity and efficiency in the financial area due to creating the new infrastructure of financial services, it should be considered only as one of many technologies based on which infrastructure of the financial services of the new generation will be formed. This is explained by the necessity of ensuring the security of the transaction. Awareness of blockchain technologies has increased greatly, however still there are significant barriers for its wide application like uncertainty in the legal area, recently emerging collective efforts on the standardization in the blockchain area, and others.

The main attributes of the blockchain are considered from the perspective of the existing theories to develop theoretical frameworks that present relevant topics and questions for logistics/SCM researchers. These frameworks are subsequently refined into research questions that can be used to create middle-range theories for further empirical testing.

6.2 Healthcare sector:

This paper also recommends medical records managing and securing blockchain systems. The system utilizes a modified cryptographic technology for producing the necessary user security key. The recommended design deploys the discrete wavelet transform in the cryptographic generator part where it produces a new key format from MD5 strings. This alteration raises the general system security and increases its immunity to various kinds of attacks. The additional decryption phase can raise the processing time to some extent. Such increment is fine where the moving data’s privacy matters.

6.3 Manufacturing sector.

This paper, therefore, lays the foundation for further systematic and theory-based research which should not only help to establish a solid research agenda but also bridge the gap between academia and the industry by pointing out those questions that researchers can tackle to better understand the blockchain and its potential implications on service sectors.
