Myths, Realities and Future

implemented to enhance transparency and faith in supply chains, their restrictions

and potential influence. Chen et al. (2019) designed an employee big data manage­

ment system based on Blockchain that solves the Blockchain information repetition

issue, analyzed the shortcomings of deploying the proposed system with Blockchain,

such as the viability of combining, and validated their ideas. Tian et al. (2019) pro­

posed a novel method of establishing a distributed key to secure the confidentiality

of healthcare information, and the simulation showed that the proposed module per­

formed effectively. Liu et al. (2017) proposed a Blockchain-based protocols frame­

work for IoT data, (Data Owner Apps) DOA to CSS-N (Cloud Storage Service),

(Data Consumer Apps) DCAs to CSS-Y, and DOA to CSS-Y, and DCAs to CSS-N

for maintaining data integrity, and found that the proposed structure could aid the

integrity validation of data blocks. Wei et al. (2020) proposed a Blockchain data-

based cloud data integrity protection mechanism by deploying a distributed virtual

machine agent framework in the cloud with the help of mobile agent technology.

Forecasting is one important area that has been extensively used by researchers in

various fields, one being forecasting of customer requirements in quality function, as

illustrated by Purohit and Sharma (2017).

10.4  MYTHS AND REALITIES OR FACTS

10.4.1  Myth 1: Blockchain Is a Magical Database in the Cloud

or Blockchain Does Not Store Any Type of Document

One popular myth is that Blockchain is some magical database in the cloud. It is a

sequential list of transaction records, which can be termed a flat file, i.e., a list that

appends entries that are never deleted, and which is duplicated in each terminal in

a P2P network. It provides the distributed ledger, i.e. the “proof-of-existence” that

certifies or indicates the presence of a definite record but not the record itself. Most

people believe that it is possible to store documents on a Blockchain, but the reality is

totally different. In reality, it only contains the information that a specific document,

such as a spreadsheet, a pdf, etc., exists. These types of documents are stored in data

lakes and can be accessed only by the owner of the document. This myth is identical

to the fact of cloud storage, which is similarly something that exists but cannot be

described. The cloud does not have any physical drive for storing information, and

the same goes for Blockchain; there is no physical storage device for Blockchain

transactions (thenextweb, 2018).

10.4.2  Reality

Blockchain does not store any document. It stores the records of transactions done;

whether failed or successful transactions, they are never deleted. In other words, it

stores the work done by the owner from start to end. In reality, as one of the myths

implies that it is cloud based, a Blockchain can be downloaded and run on Internet-

enabled computers for operational functions.
