Blockchain technology has been gaining popularity in recent years and has inspired both innovation and skepticism. Written for business decision makers and students, this text provides an overview of the history, current applications, and future potential of distributed ledgers and cryptocurrency. Strengths, weaknesses, growing opportunities, and potential threats are all discussed. This book keeps a business context in mind when introducing technical frameworks, helping strategists understand both risks and rewards of various blockchain implementation approaches as well as factors that influence whether or not this is a practical solution for current problems. Chapter 1 discusses the emergence of blockchain along with some of its potential successes and challenges. Blockchain and its potential contributions have created skepticism, mostly due to its link to Bitcoin. Just like any new technology, blockchain-technically a subset of Distributed Ledger Technology (DLT)-has its own jargon to explain its features; several of these terms are described. The chapter goes on to compare the emergence of blockchain to that of the internet. Just as the internet disrupted the current world and delivered unexpected change so too can blockchain. But the reputation of cryptocurrency has been one of criminality; however, it is a natural evolution of the money system, which relies on mutual trust. While commonly misunderstood, blockchain is a database holding strings of encrypted information. It cannot be tampered with because each block has a fixed position in the chain: Changing the data in one block means changing the data in all those that follow it. Utilizing blockchain can streamline processes, cut out costs, improve lives, and reduce risk.

Chapter 2 begins by discussing challenges of digital currency: knowing that a transaction has been completed correctly and being accepted as a symbol of value without recourse to traditional physical reserves. David Chaum's original ideas and principles of cryptography are described. An overview of the Cypherpunk movement is given. Satoshi Nakamoto's blockchain proof of concept finally put into place a working decentralized mechanism for the prevention of double spending via Bitcoin; features of Bitcoin are discussed. The chapter then explores Ethereum, the first blockchain infrastructure purpose-built for distributed computing. "Smart contracts" are rules for a transaction laid out in ledger's code and are essential to Ethereum. Cryptokitties is used as an example of smart contracts managing digital asset transactions. Past infighting within the Bitcoin and Ethereum communities is described. The expanding of blockchain technology into enterprise has a few unique challenges, especially privacy and verification. Permissioned blockchain solves those problems, replicating all the benefits of blockchain as a transparent, immutable record but eliminating the anonymity of users and open viewing of transactions and smart contracts.

This chapter describes the rise in the number of cryptocurrencies, how some of them have been innovative, but how most are not good business projects and are often scams. This gave Bitcoin and blockchain a bad reputation. However, this chapter argues that cryptocurrency was thrown into an already broken system. When it comes to token fundraising, new ideas are constantly being proposed, some of which people should be wary of. The importance of and differences between utility and security with tokens are discussed. Legislative issues surrounding blockchain and cryptocurrency are also described for several countries, including the United States, the United Kingdom, France, and some smaller states. Various types and classes of cryptocurrencies and their different features are described, including Monero, stablecoin, and XRP. Cryptocurrency is gaining popularity in many countries, especially where it has utility for users. It could in a sense "bank the unbanked." Cryptocurrency started with the intention of being money for the people, decentralized and unfettered by agency or authority, but users have made it into de facto banks. Ultimately, if cryptocurrency is truly going to be embraced, there must be a real advantage over the status quo.

Chapter 4 explores the potential future and value of blockchain. Blockchain is a great tool to solve many problems in the most appropriate way; however, a major threat to distributed ledger technology is using blockchain as the default, manipulating the solution to fit, and forgetting the original problem in the process. This chapter looks at when blockchain is truly needed as well as its real-world applications and addresses the misunderstanding that blockchain is a repository of absolute truth. The relationship between supply chain and distributed ledger technology is discussed. Case studies and examples are given. When it comes to the traditional centralized banking system, blockchain-based systems can deliver greater transparency, confidence in records, and long-term savings. Blockchain technology can also help overlay confidential data repositories with a layer of encryption and enable access for only those parties with the right key. This could also be helpful in areas such as medical records. Infrastructure management can also benefit from blockchain and distributed ledgers; management of energy distribution and addressing the full lifecycle of large capital projects are specifically explored.

This chapter turns to the gaming world. Gaming has inspired the development of concepts that could not have been otherwise realized without blockchain. This chapter specifically looks at the idea of ownership in games, nonfungible tokens (NFT), and the phenomenon of paying to play. Three characteristics of gamers in the blockchain space are given by Gabby Dizon: collectors, investors, and players. The emerging game economy must have a balance between these types of users. Community management is a new discipline important in holding the attention and loyalty of consumers; community is also a vital aspect of blockchain and cryptocurrency adoption. NFT principles can be applied to sectors outside of gaming, including supply chain generally. Scalability of blockchain, speed, and sharding are also discussed. One of the approaches to scaling has been the development of side chains as another layer on established protocols. Examples of side chains and practical considerations for scaling blockchain projects are given.

This chapter is all about data. It discusses the process of owning our data, the implementation of blockchain within government, and legal considerations for organizations adopting distributed ledger technology. Personal information is often stored digitally and publicly now, but these lists started being hidden from public view as privacy awareness grew. The idea of privacy versus surveillance is discussed as is the importance of digital identity. Blockchain can be used for identity verification and recording, verifying, and keeping safe other aspects of personal data. Blockchain can also be used in many areas of government. Digital assets, land registries, real estate, and trust in elections are all explored in relation to blockchain. Challenges of blockchain development are also addressed, including automation of processes, branding and intellectual property, and data protection.

Chapter 7 deals with potential opportunities for blockchain as well as threats. A major issue is the sustainability of the technology. The amount of energy required for blockchains is phenomenal, but the option of renewable energy is not always welcomed. Efficiency of processors, recycling, and reusing are other sustainability issues that blockchain and cryptocurrencies face. This chapter also discusses the question of whether or not blockchain is actually needed in many instances. Immutability of information and archiving pose threats to blockchain integrity. While cryptocurrency is founded on decentralization, the difficulty of keeping it decentralized is rising as blockchains grow and go back for decades. The question of quantum computing and its potential impact on cryptography are also discussed. Blockchain can be applied to accounting, auditing, and commercial letters of credit. Blockchain has the potential to change society, but that must include education and support to harness opportunities.
