Bitcoin and Cryptocurrency Technologies
The digital currency Bitcoin and its underlying technology, the blockchain, have taken the world by storm. Supporters claim that they will fundamentally reshape payments, economics, and even politics around the world. Skeptics say that they are a haven for fraud and will suffer an inevitable and spectacular collapse. This talk will provide an accessible introduction to Bitcoin and the blockchain.
We will trace their development to the history of activist movements advocating privacy and civil liberties through cryptographic technology. Through this we will appreciate the true potential of crypto-currencies, as well as their limits. We will see past the hype and use Bitcoin as a case study of how technology rearranges power.
Arvind leads a research group at Princeton studying the security, anonymity, and stability of Bitcoin and other blockchain technologies. He also leads the Web Transparency and Accountability project at Princeton studying how companies collect and use personal information.
He received the Privacy Enhancing Technologies Award for this work. He is the lead author of a textbook on Bitcoin and cryptocurrencies. He teaches a Massive Open Online Course on the same topic, which had 35, students in its first iteration. He is the recipient of the first U. President Larry Millstein called the th meeting of the Society to order at p. He announced the order of business and welcomed new members. The minutes of the previous meeting were read and approved.
Narayanan began by explaining the origins of cryptocurrencies. This proved indecipherable for several centuries, up through the Civil War, but was eventually rendered obsolete by the late s. In the s, computing techniques were applied to cryptography and the first modern encryption began to appear.
Quantum computing may one day disrupt this status quo, if it becomes feasible, but quantum-resistant encryption can be operated on standard computers, and early versions have in fact already been made available in modern web browsers. For the foreseeable future, the arms race has been fundamentally tilted in favor of the code makers.
The strength of encryption provoked a response from the U. This effort, which became known as the First Crypto War, ultimately failed by the early s in large part because the underlying equations were so simple to implement and share. Narayanan explained that the developers of modern cryptography perceived an explicit political dimension to their work, designing systems that would combat the increasing reach of computerized government surveillance.
Bitcoin is one concrete artifact of this vision of private, decentralized, ungoverned systems. Bitcoin is a peer-to-peer system. Bitcoin transactions are signed with the private key of the user, and then broadcast to the entire Bitcoin network. The goal of the protocol is to record every transaction in a global, immutable, public ledger known as the blockchain. Each block added to the chain includes a cryptographic digest of the previous block to ensure that no block can be changed once it is entered.
Those computers that agree with the ultimate consensus are rewarded in Bitcoin proportional to the computing power they contributed to resolving the discrepancy. Computers demonstrate their processing power to the network by completing computationally hard problems as proof-of-work.
Currently, there are about a trillion trillion operations performed for each block, and a new block is added every ten minutes. The anonymity of Bitcoin naturally lends itself to illegal activity, such as the online marketplace Silk Road, but Bitcoins are also useful for addressing a host of morally legitimate problems such as reducing transaction costs and sending international payments.
Narayanan concluded by explaining that the underlying technology of modern cryptography is sound and powerful, enough so to provide a trusted basis on which to improve and augment our existing legal, social, and political institutions.
After the conclusion of the talk, President Millstein invited questions from the audience. One questioner asked whether a government could destroy Bitcoin by applying sufficient computing power to seize control of the blockchain.
While theoretically possible, Dr. Narayanan explained, this would likely be impractical and prohibitively expensive, out of proportion to the threat Bitcoin might pose to such a government. Narayanan explained that the task involves hashing random numbers to the existing blockchain to see if they produce an output hash that satisfies the properties specified in the Bitcoin protocol. After the question and answer period, President Millstein thanked the speaker, made the usual housekeeping announcements, and invited guests to join the Society.

He huddled with Joseph Lubin, a former roommate and one of the co-founders of the hit cryptocurrency platform Ethereum. Princeton, like Wall Street, where Novogratz has made at least three fortunes and lost at least two, is full of stories about him.
Bitcoin, Blockchain, and Cryptoassets
Sick of hearing about blockchain? Get used to it. Crypto-mania is not going away. Here's the latest evidence: Across America's top universities , enrollment is skyrocketing in blockchain and cryptocurrency courses. These courses hardly existed a few years ago. Now universities with classes on the subject are having to either turn students away or find ways to expand enrollment. When New York University's Stern School of Business first offered a course on blockchain and financial services in , only 35 students signed up. Last spring, enrollment jumped by more than percent to students.

Blockchains Are a Diamond’s Best Friend
Princeton is giving people the opportunity to learn about Bitcoin for free. The Princeton Bitcoin textbook is a comprehensive write up on the digital currency created by Satoshi Nakamoto and contains over pages. Narayanan says:. Researchers and advanced students will find the book useful as well. Enter Bitcoin.
Bitcoin profiles near Princeton
By Gertrude Chavez-Dreyfuss. Digital Currency Group confirmed its investment in basecoin. Bain Capital, Pantera, and Andreessen Horowitz were not immediately available to comment. The investors had bought a unit of Intangible Labs, which entitled them to basecoin - a token with a rules-based monetary policy built into its blockchain system - in the future, Al-Naji said in an interview with Reuters on Friday. He did not disclose an investment figure. Blockchain, a digital ledger of transactions, underpins crypto-currency bitcoin and can be used to track, record, and transfer assets across all industries. Intangible Labs is one of many blockchain start-ups creating and distributing tokens to investors to raise funds for their projects. Start-ups typically hold a token pre-sale to institutional investors before opening the token offering to the public.

Gavin Andresen born Gavin Bell  is a software developer best known for his involvement with bitcoin. He is based in Amherst, Massachusetts. Originally a developer of 3D graphics and virtual reality software, Andresen became involved in developing products for the bitcoin market in , and was declared by Satoshi Nakamoto as the lead developer of the reference implementation for bitcoin client software after Nakamoto announced their departure. Andresen graduated from Princeton University in In , he co-authored the VRML 2.
