Introduction

### Course Review: Introduction to Blockchain Technologies #### Overview The course "Introduction to Blockchain Technologies" on Coursera is an exemplary starting point for anyone looking to understand the transformative power of blockchain. As we transition into what some are calling the “second era of the Internet,” this course provides invaluable insights into the technological innovations that could redefine the way we conduct business and engage in economic activities. Throughout this course, learners are introduced to the critical limitations of the conventional Internet, particularly its inadequacy in handling value transactions. This sets the stage for a comprehensive exploration of blockchain technology, which promises to facilitate peer-to-peer transactions without the need for trusted intermediaries. By the end of the course, participants will not only grasp the mechanisms behind blockchain but also appreciate its potential as a revolutionary economic driver. #### Syllabus Breakdown 1. **The Second Era of the Internet** - The course begins with an essential insight into the evolution of the Internet and the emergence of blockchain as a solution to previous limitations. This module emphasizes blockchain as a "trust protocol," showing how it fosters trust through collaboration and advanced cryptographic techniques rather than traditional intermediaries. 2. **Blockchain Design Principles** - This segment outlines seven design principles that underline the blockchain revolution. Each principle is tied to real-world problems, detailing how blockchain innovations can resolve these issues and reshape various facets of the digital economy. It equips learners with a conceptual toolkit to think critically about blockchain’s applications in business and governance. 3. **Public and Private Ledgers** - A crucial aspect of blockchain is understanding its two types: public and private ledgers. This module delves into the implications of transparency in blockchain transactions and the various considerations surrounding privacy. It teaches necessary techniques to protect sensitive information, ensuring that participants are well-versed in the nuances of both types of ledgers. 4. **The Blockchain Ecosystem** - The course highlights the diverse array of stakeholders involved in the blockchain landscape, from developers to regulators. This portion of the curriculum provides context on how various perspectives shape the evolution of blockchain technology and its applications within the economy. 5. **Blockchain Implementation Challenges** - Finally, addressing the realities of adopting new technologies, this module discusses the ten major challenges faced during blockchain implementation. With a focus on potential solutions, it encourages learners to think critically about the hurdles that the blockchain industry must navigate. #### Recommendations **Who Should Take This Course?** Whether you’re a business professional looking to innovate your company’s approach, a student interested in future technologies, or simply someone curious about the potential of blockchain, this course is an excellent fit.

The Second Era of the Internet

The Internet connects billions of people around the world, and is great for communicating and collaborating online. However, because it was built for moving and storing information, and not value, it has done little to change the way we do business. Now, for the first time in human history, two or more parties anywhere in the world can transact and do business peer to peer using the blockchain. In this module we introduce blockchain as “the trust protocol,” and explain how it represents the second era of the Internet. We describe how blockchain technology establishes trust—not through powerful intermediaries, but rather through collaboration, cryptography and clever code.

We believe that the next era of the digital economy can be shaped around a set of blockchain design principles, which can be used for creating software, services, reinventing business models, markets, organizations, and even governments. This module frames the blockchain revolution around seven design principles. For each principle we describe a current problem to be solved, identify “blockchain breakthroughs” to these problems, and discuss the implications of these breakthroughs on the digital economy. We hope that these design principles will assist learners in contemplating their roles and their futures in the blockchain revolution.

The advent of blockchain technology forces us to reconsider the upside and downside of public revelation of transactions and contracts. The implementation, application, and possible regulation of distributed ledgers involve choices that will critically affect information disclosure and economic interactions. Whether the ledger is public and permissionless, such as the Bitcoin or Ethereum blockchains, or private and permissioned, such as the Ripple or Hyperledger implementations, in principle transactions on a blockchain have a high native level of transparency. In this module, you will learn how privacy can can be protected in both public and private ledgers using both procedural and technological methods.

Although blockchain technology emerged from the open source community, it quickly attracted many stakeholders, each with different backgrounds, interests, and motives. In this module, you will explore the roles and perspectives of nine categories of stakeholders within the blockchain ecosystem, including industry pioneers, venture capitalists, developers, governments, regulators, leaders, and end users.

Like every revolutionary technology, the blockchain has its upside and its downside. In this module we discuss ten implementation challenges which must be overcome as we transition to the second era of the Internet. For each challenge, you will also learn about potential solutions and what we can do to ensure the fulfillment of the blockchain’s promise.
