To encourage industry discussion of cutting-edge blockchain applications, this chapter was written. This chapter provides an introduction to blockchain technology as well as details on how to secure transactions using technology and how the secure element works. It examines common implementation worries and provides use cases for current commercial or trial projects. The following paragraphs go over the concept of a blockchain, how bitcoin transactions operate, and how to finish a transaction. The network of Marco Polo will be highlighted. In this chapter, the authors show how to use blockchain and cloud technology with Marco Polo to remove corporate pain problems. The chapter goes on to give a full overview of blockchain, including its function, traits, and applications.
TopIntroduction
Providing Blockchain Technology as a Service Distributed ledger technology (Bitcoin) platforms are offered by third-party suppliers so that companies may create their own blockchain-based applications. It's possible to conduct many kinds of transactions and checks using blockchain-based applications. Thus, programmers that handle financial transactions, hold identities, and coordinate supply chains are among of the most common blockchain uses. Even Nevertheless, there are several scenarios in which a blockchain-based programmer may be valuable (Haleem et al., 2021).
Most companies choose to work with blockchain as a service providers rather than build their own blockchain infrastructure so they can run enterprise-level apps. Subscription-based cloud platforms allow customers to build applications without investing capital into servers, complex infrastructure, or dedicated IT staff. Firms offering blockchain as a service are responsible for managing the underlying hardware (Haleem et al., 2021).
According to Haleem et al., (2021) that there are numerous parallels between blockchain platforms and blockchain-based solutions provided as a service. Several businesses now provide their own proprietary platforms, often in addition to a hosted “as a service” option, to better serve their customers. Contrarily, maintaining a traditional platform is substantially more work than maintaining a cloud-hosted software service (Haleem et al., 2021).
To be included in the Blockchain as a Service Providers group, an application must satisfy the following requirements:
- •
Built on top of a blockchain or other distributed ledger system.
- •
Provide access to a hosted, shared database that supports transactions.
- •
They should provide a development setting and/or premade tools to make it easier for others to create blockchain-based applications.
- •
Provide ways for users to make the app their own and add new features.
There has been discussion over the use of private block chains in commercial settings. Computerworld referred to the selling of such privatized block networks without a good security architecture as “snake oil” (Gökalp et al., 2018).

Bitcoin blockchain structure
Figure 1 contains a number of blocks that illustrate the construction of the Bitcoin blockchain. These blocks are indicated in the figure.
The innovation of blockchain is rather recent. A blockchain is “a continually increasing rundown of documents, called squares which are joined and anchored via encryption.” They will differentiate a delegate evaluation of flow topics in blockchain and investigate as well as analyses the potential repercussions of our ideas. Even though blockchain is probably not well known, it is rapidly emerging as a medium, and it is a topic that is being discussed in the media with a great deal of intensity right now (Gökalp et al., 2018).
