This Is the Primer You Need to Understand Bitcoin
Can you hear that? A certain high frequency hum which, until recently, was perceptible only to dogs, bats, and cryptography cognoscenti? Due in large part to the way they address the twinned threats of system failure and malicious users which plague our increasingly bloated, outmoded, centralized systems of exchange, blockchains already appear to be altering institutions that have structured human life and interaction for centuries.
More radical in their re imagining of system reliability and trustworthiness than cloud computing, social networks, or the Internet of Things, blockchain-based technologies like Bitcoin are certainly a massive phenomenon. But what is a blockchain? How does it work? And can it actually deliver on what it ostensibly promises? This lesson may be deployed in rhetoric and writing-intensive courses, as it regards blockchain through the lens of ethos and decentralized network exchange i.
It may also be used for a course more narrowly focused on political action or public discourse, as it provides insight into the promises, potentialities, and public effects of one of the most transformative technologies of our time.
Students will learn the general contours of blockchains, broadly construed, from a nontechnical perspective. This lesson plan presents a rhetorical reading of shared ledgers and asks students to analyze constructions of ethos in older models of distributed agency as well as newer blockchain-based technologies. This means they will come away with a rudimentary understanding of:. Classroom equipped with projector and computers. Some prior coverage of appeals to ethos and concepts like digital identity, ownership, and exchange would be helpful.
No technical skills necessary beyond web browsing and collaborating on digital media. Hoping to be as flexible as virtual networks of exchange and consensus-building, themselves, this lesson plan is adaptable to a variety of classroom settings, instructor goals, and student needs.
Further, if you ask students to bring their own devices to class it will better accommodates those with accessibility software installed on their personal computers. Since this lesson involves reading and viewing web content, there should be a number of workarounds available for those requiring disability accommodations like 1.
In terms of content adaptability, you might choose to focus closely on the potential for blockchain technologies to increase political , social , or economic interaction including its purported access-granting and democratizing effects or conduct classroom discussion toward the promises and pitfalls of decentralized networks, P2P, and blockchain with regard to accessibility and the digital divide, specifically. Students will be introduced to concepts of distributed agency, decentralized networks, virtual exchange, and the latest innovation of blockchains.
They will be asked to think critically about the rhetorical appeals to ethos made in each technological instance and ultimately approach the new wave of technology with a sophisticated, skeptical eye.
The hype around blockchain is considerable, but how grand should expectations really be? What ethics are involved in the gold-rush mentality surrounding, for example, Bitcoin? Blockchain may offer greater reliability, transparency, and security to users i. For example, why is it that some of the institutions that this technology is designed to dismantle or make obsolete are the very ones stocking up on blockchain patents or collaborating with blockchain startups?
Consider the chronological development of decentralized networks and how social, political, and economic pressures molded these technologies and their legacies. Potentially adapt the topic to suit your particular classroom culture. Read whatever articles the instructor chooses to assign before class hyperlinked and listed in Skills Workshop. Watch videos, making note of how blockchain technologies conceive of and extend concepts of reliability and trustworthiness.
Participate in class research and discussions about ethos, reliability, and trustworthiness on blockchains. Additionally, you may select videos from those hyperlinked in the Skills Workshop section for students to watch prior to class. If necessary, provide a brief recapitulation of ethos as a rhetorical appeal, reiterate the investment rhetoric and composition have in constructing and transmitting concepts of good character, reliability, and trustworthiness 10 minutes.
Divide students into groups of and assign each group a specific revolutionary network to research and discuss 30 minutes. Have each group present their research to the class, as a whole 20 minutes. For the remaining time or as a post-class, online assignment ask students to discuss how ethos was conceived of and constructed within these early P2P networks and how shifts in technological reliability and social trustworthiness drove progress of distributed systems.
Have them pay special attention to the claims made about ownership, identification, authentication, and authorization, and how blockchain intervenes on each.
Additionally, you may select articles or videos from those hyperlinked below to assign. Review the generic-use patterns of blockchain that Drescher identifies : Proof of existence, proof of nonexistence, proof of time, proof of order, proof of identity, proof of authorship, and proof of ownership. Pretty fuzzy, eh? To make your discussion more concrete, divide students into groups they could be the same as the previous class period or different and assign each a specific application area of blockchain technologies to research 30 minutes.
These might be: 1 Financial instruments, records, and models e. Have each group present their research to the class, as a whole 20 minutes, total. For the remaining time or as a post-class, online assignment ask students to define in their own words what the main differences between earlier P2P models and blockchain models are. You might ask them to discuss how ideas of ethos shift between the P2P networks they researched during the last class period and the application areas they looked at during this class.
Further, how have changes in our expectations of technological reliability and social trustworthiness driven the narrative of progress within distributed systems?
Finally, you could assign a more long-form essay on the rhetoric of blockchains: what are some of the problems these technologies are meant to solve? How do they aim to solve them i. What claims do they make about financial, educational, governmental, or judicial processes and what are the potential risks associated with such social and political transformation? Since this lesson is explores a digital topic and requires some computer use both in and out of the classroom, but does not demand any special skills or programming knowledge, what I offer below is a collection of additional sources to inform your teaching and generate student discussion.
This list is by no means exhaustive…though it might initially look exhausting. Instructors should familiarize themselves with the media presented here, which are meant to convey the general contours of this topic as well as highlight a few interesting little detours worth exploring. If certain texts or videos speak more to the goals of a particular course, the lesson plan can be augmented or steered in that direction. Introduction to Blockchain Parts Unonimity.

What is a peer to peer system? How the blockchain will radically transform the economy Ted Talk. The following are Portfolio-Style and Traditional Assessment suggestions. In both, students are assessed on the extent to which they generate a portfolio or contribute to a discussion that rhetorically analyzes distributed networks, blockchain technologies, and how we construct ethos on anonymous, global platforms of exchange.
These class periods and their attendant assignments can be developed into a student portfolio project in at least two ways. Second, groups or individual students might focus on one overarching metaphor used to describe the evolution of P2P and blockchain technologies and discuss the broader rhetorical claims of distributed networks and ethos in a brief paper.
Instructors should moderate GoogleDocs or LMS contributions and offer ample feedback as to about how students can improve the project prior to its due date, either in-person or on the sites.
The in-class and online discussion can be incorporated into an overall participation grade. Additional points might be awarded for further research and writing assignments on the topic.

Lesson Plan: Assessing Reliability and Trustworthiness with/in Blockchains
Yesterday, the identity of the inventor of Bitcoin was reportedly revealed as Craig Steven Wright , a secretive Australian man. Today, a lot of people find themselves with the question: What is Bitcoin? It's a good question. Bitcoin is a confusing topic, a "Cryptocurrency" that is mined through computers helping run encryption math problems, with coins rewarded per solution discovered.
What is Blockchain? Explained The Easy Way
Video viewing is predominantly an online pastime. Streaming services like Netflix have changed the face of media forever. And sites like YouTube rely on centrally collected videos that they send to devices on demand. This isn't the only way it can work though, and DTube is an example of a decentralized video network. Today we'll look at what DTube is and how it works, but first, let's look at how online video sites usually work.
The Escalating Threat of Cryptojacking in 2021
This is a list of readings and watchings on blockchain related topics. The word "blockchain" or "block chain" started off as a more or less narrowly defined technical term. It "blockchain" later became a buzzword that represented anything related to BitCoin, alt-coins ex: LiteCoin, Ethereum, etc , cryptocurrencies, etc. And now that the word "blockchain" is on the verge of becoming a household name , it seems like it is starting to include what some others used to call "P2P" , and are now calling "distributed computing". In some usages of the label "blockchain" , neither blocks or hash lists seemed to be necessary for that thing to be called a "blockchain".
How Bitcoin Works – Computerphile
An ongoing cryptocurrency bear market is not dampening interest for Fidelity's new institutional cryptocurrency products. Fidelity Digital Assets, a new company created by the investing giant last year, has quietly rolled out its cryptocurrency custody and trade execution operations. In the past few months it has been up and running with institutional investors like hedge funds and family offices, according to its top executive.
In this article, we are going to discuss what is cryptojacking, what is crypto mining, the rise of cryptojacking, cryptojacking examples, and how can it be prevented. Cryptojacking definition is a form of crime committed in the cyber world involving unauthorized access to catch hold of cryptocurrencies. Like any other cybercrime, cryptojacking is solely committed for profit. However, unlike other cybercrimes, cryptojacking is designed in a way that is completely hidden from the victim. Cryptojacking is a cybercrime committed to mine cryptocurrencies.
Christine Kim. Over the past decade, the machines that maintain the Bitcoin network have undergone rapid technological development. Mining equipment is a fundamental feature of the success of the bitcoin network because these machines determine whether or not it is profitable for miners to do what they do — that is, process the calculations needed to embed blocks of transactions on the blockchain. While somewhat overlooked, the history of bitcoin mining equipment is also a key explanation for why the activity of mining has evolved over the years into a multi-billion dollar industry. The mining industry continues to evolve today, though there are signs to suggest its development is slowing down. Below we take a look at the complete history of bitcoin mining technology, and where innovations could be heading next. On Jan.
