NFTs Non-fungible tokens

An NFT is a digital asset that represents real-world objects like art, music, in-game items and videos. They are bought and sold online, frequently with cryptocurrency, and they are generally encoded with the same underlying software as many cryptos. are “fungible,” meaning they can be traded or exchanged for one another. They’re also equal in value—one dollar is always worth another dollar; one Bitcoin is always equal to another Bitcoin. Crypto’s fungibility makes it a trusted means of conducting transactions on the #blockchain. NFT has a digital signature that makes it impossible for NFTs to be exchanged for or equal to one another (hence, non-fungible). An NFT is created, or “minted” from digital objects that represent both tangible and intangible items, including:

  • Art
  • GIFs
  • Videos and sports highlights
  • Collectibles
  • Virtual avatars and video game skins
  • Designer sneakers
  • Music

Twitter co-founder Jack Dorsey sold his first ever tweet as an NFT for more than $2.9 million. NFTs can have only one owner at a time. Blockchain technology and NFTs afford artists and content creators a unique opportunity to monetize their wares. celebrities like Snoop Dogg and Lindsay Lohan are jumping on the NFT bandwagon, releasing unique memories, artwork and moments as securitized NFTs.

This essay proposes the need to infuse open innovation (OI) and open source (OS) principles and technologies into schools as a means of tackling many of the most pervasive challenges in education, and by extension, society at large. It is argued that the principles of OI and OS, which are rooted in innovation management and software development, respectively, may be applied to the way we conceive of and approach organizational governance structures related to schooling, particularly in regard to harnessing innovation, updating management processes, and codifying new systems of trust. Whereas OI offers a novel approach to knowledge flow and the open exchange of ideas, communities rooted in OS principles breed tangible and generative effects through peer network democratization. These emergent, digitally defined networks have been proven to maximize innovation potential, expand collaboration, and enable the propagation of highly durable systems of trust and transparency, all catalytic and essential if we are to realize a future learning economy which favors equity, distributed systems, and common goods over profit, centralized decision-making, and proprietorship. It is within this framing that we articulate the core tenets of both OI and OS translationally as a means of stimulating thinking about how core principles of “openness” and the distributed technologies they enable may help to build common ground in an ever-evolving education and information ecosystem.

Blockchain is often presented as a technological development; however, clearly it is not only that: the ‘Blockchain buzz’ exists in the context of current social and political developments. In this essay, we analyse blockchain technology and its social and political context from a perspective of Marxist economic theory. Since arguably the last great inflection point in society and technology was analysed by Marx in terms of labour and capital and since we seem to be experiencing a shift in the balance between these forces today, it makes sense to revisit the Marxist ideas and apply them to the current situation, to see how well they still apply and if necessary to update them for current events.

One of the rallying cries of the blockchain community is that of immutability: the irreversibility of the past, the absolute truth which, once stored, remains there forever. The technology was designed with this foundational pillar in mind to ensure that changes to history are inordinately expensive and practically impossible to execute – and increasingly so, the further in the past the event which one intends to manipulate lies. This platonic view of absolute truth is in stark contrast with a world of manipulated truth, and it is not surprising that it is being revisited as a means of combating fake news. We argue that claims to the absolute nature of the blockchain are at best exaggerated, at worst misrepresented or even ‘fake news’. We discuss implicit centralised points of trust in blockchains, whether at a technological, social or governance level, and identify how these can be a threat to the ‘immutable truth’ stored within the blockchain itself. A global pandemic has unleashed an unprecedented wave of contradictory positions on anything from vaccines and face masks to ‘the new normal’. It is only natural that the pursuit of blockchain as a placebo for society’s ‘truth’ problems continues.

AR blockchain doritos

“Using #augmentedreality (#AR) and #blockchain technologies, the game featured ‘Vatoms’, virtual objects that players can interact with.
Due to pandemic restrictions, the game, originally developed as an outdoor activity in other markets, was adapted to allow people to hunt for the packs in and around their own homes. Packs contained either Playstation symbol chips or an instant-win prize, which would then be stored in a digital wallet.”

Imagine, if it was not Doritos, but bones to build a skeletal system (Biology, nursing, medicine, etc.), philosophers (Philosophy, political science, social sciences) and the rewards or badges in the leaderboard. #gaming and #gamification

UC Berkeley Will Auction NFTs for 2 Nobel Prize Patents

https://www.insidehighered.com/quicktakes/2021/05/28/uc-berkeley-will-auction-nfts-2-nobel-prize-patents

Nonfungible tokens — called NFTs for short — are units of data stored on the blockchain that are unique and not interchangeable. As NPR recently explained, a $10 bill, which is fungible, could be exchanged for two $5 bills. An NFT is one of a kind, more like a barcode.

The public research university, according to a press release, is auctioning the NFTs for the patent disclosures of two Nobel Prize-winning inventions: CRISPR-Cas9 gene editing, for which UC Berkeley’s Jennifer Doudna shared the 2020 Nobel Prize in Chemistry; and cancer immunotherapy, for which James Allison shared the 2018 Nobel Prize in Physiology or Medicine.

The university will continue to own the related patents.

VR in business school

Temple’s business school sees virtual reality as future of online learning

https://www.inquirer.com/business/remote-learning-vr-mba-20210423.html

a finance professor at Temple University and academic director of its online MBA, has tested that belief since March 2020, when he launched the class Fintech, Blockchain and Digital Disruption in a virtual reality, or VR, program.

It took 18 months to research the technology and build the course at a cost upward of $100,000. The finished product was completed with the help of Glimpse Group, a New York-based virtual reality and augmented reality company.

“When I teach classes on Zoom, there’s a disconnect,” Ozkan said. “When we asked students last year to compare their VR experience to Zoom, almost all of them said [VR] is better or much better. Which is why we decided to offer it again this year.”

When the 18 students enrolled in the seven-week accelerated course this semester put on their VR headsets, they entered one of two lecture halls modeled after actual rooms on the Temple campus. Students customize their avatars before the semester.

Learn Blockchains by Building One

The fastest way to learn how Blockchains work is to build one

Daniel van Flymen  Sept 24, 2017

https://hackernoon.com/learn-blockchains-by-building-one-117428612f46

Remember that a blockchain is an immutable, sequential chain of records called Blocks. They can contain transactions, files or any data you like, really. But the important thing is that they’re chained together using hashes.

If you aren’t sure what a hash is, here’s an explanation.

reading and writing some basic Python, as well as have some understanding of how HTTP requests work, since we’ll be talking to our Blockchain over HTTP.

Blockchain next election

Blockchain Disciples Have a New Goal: Running Our Next Election

Amid vote-hacking fears, election officials are jumping on the crypto bandwagon — but cybersecurity experts are sounding an alarm

At democracy’s heart lies a set of paradoxes: a delicate interplay of identity and anonymity, secrecy and transparency. To be sure you are eligible to vote and that you do so only once, the authorities need to know who you are. But when it comes time for you to mark a ballot, the government must guarantee your privacy and anonymity. After the fact, it also needs to provide some means for a third party to audit the election, while also preventing you from obtaining definitive proof of your choice, which could lead to vote selling or coercion.
Building a system that accomplishes all this at once — and does so securely — is challenging enough in the physical world. It’s even harder online, as the recent revelation that Russian intelligence operatives compromised voting systems in multiple states makes clear.
In the decade since the elusive Satoshi Nakamoto published an infamous white paper outlining the idea behind bitcoin, a “peer-to-peer electronic cash system” based on a mathematical “consensus mechanism,” more than 1,500 new cryptocurrencies have come into being.
definition: Nathan Heller in the New Yorker, in which he compares the blockchain to a scarf knit with a single ball of yarn. “It’s impossible to remove part of the fabric, or to substitute a swatch, without leaving some trace,” Heller wrote. Typically, blockchains are created by a set of stakeholders working to achieve consensus at every step, so it might be even more apt to picture a knitting collective creating that single scarf together, moving forward only when a majority agrees that a given knot is acceptable.
Unlike bitcoin, a public blockchain powered by thousands of miners around the world, most voting systems, including Votem’s, employ what’s known as a “permissioned ledger,” in which a handful of approved groups (political parties, election observers, government entities) would be allowed to validate the transactions.
there’s the issue of targeted denial-of-service (DoS) attacks, in which a hacker directs so much traffic at a server that it’s overwhelmed and ceases to function.
Although a distributed ledger itself would likely withstand such an attack, the rest of the system — from voters’ personal devices to the many servers a vote would pass through on its way to the blockchain — would remain vulnerable.
there’s the so-called penetration attack, like the University of Michigan incursion, in which an adversary gains control of a server and deliberately alters the outcome of an election.
While it’s true that information recorded on a blockchain cannot be changed, a determined hacker might well find another way to disrupt the process. Bitcoin itself has never been hacked, for instance, but numerous bitcoin “wallets” have been, resulting in billions of dollars in losses. In early June 2018, a South Korean cryptocurrency exchange was penetrated, causing the value of bitcoin to tumble and resulting in a loss of $42 billion in market value. So although recording the vote tally on a blockchain introduces a new obstacle to penetration attacks, it still leaves holes elsewhere in the system — like putting a new lock on your front door but leaving your basement windows open.
A blockchain is only as valuable as the data stored on it. And whereas traditional paper ballots preserve an indelible record of the actual intent of each voter, digital votes “don’t produce an original hard-copy record of any kind,”
In the end, democracy always depends on a certain leap of faith, and faith can never be reduced to a mathematical formula. The Economist Intelligence Unit regularly ranks the world’s most democratic counties. In 2017, the United States came in 21st place, after Uruguay and Malta. Meanwhile, it’s now widely believed that John F. Kennedy owed his 1960 win to election tampering in Chicago. The Supreme Court decision granting the presidency to George W. Bush rather than calling a do-over — despite Al Gore’s popular-vote win — still seems iffy. Significant doubts remain about the 2016 presidential race.
While little doubt remains that Russia favored Trump in the 2016 election, the Kremlin’s primary target appears to have been our trust in the system itself. So if the blockchain’s trendy allure can bolster trust in American democracy, maybe that’s a net positive for our national security. If someone manages to hack the system, hopefully they’ll do so quietly. Apologies to George Orwell, but sometimes ignorance really is strength.
