Metaverse for Education - How will the metaverse change education?

Metaverse for Education - How will the metaverse change education? | 21st Century Learning and Teaching | Scoop.it

The critical concern for any metaverse beginner would pertain to the ways in which metaverse can change education. How will the metaverse change education? The big question brings many doubts to mind alongside emphasizing particularly the specific parts of the metaverse, which might play a role here.

A broader classification of the metaverse would bring you face to face with four important concepts such as augmented reality, lifelogging, virtual reality, and mirror worlds. All of these concepts provide a detailed impression of using metaverse technology to drive use cases in the education sector. Let us learn about these four aspects of the metaverse with a brief overview of each of them.

The Blockchain Economy: A beginner’s guide to institutional cryptoeconomics | #Blockchain

The Blockchain Economy: A beginner’s guide to institutional cryptoeconomics


Chris Berg, Sinclair Davidson and Jason Potts are from the RMIT Blockchain Innovation Hub, the world’s first social science research centre into the economics, politics, sociology, and law of blockchain technology.

The blockchain is a digital, decentralised, distributed ledger.

Most explanations for the importance of the blockchain start with Bitcoin and the history of money. But money is just the first use case of the blockchain. And it is unlikely to be the most important.

It might seem strange that a ledger — a dull and practical document associated mainly with accounting — would be described as a revolutionary technology. But the blockchain matters because ledgers matter.

‘Mind-Boggling’ Math Could Make Blockchain Work for Wall Street | #ICT 

‘Mind-Boggling’ Math Could Make Blockchain Work for Wall Street | #ICT  | 21st Century Learning and Teaching | Scoop.it
A major breakthrough in cryptography may have solved one of the biggest obstacles to using blockchain technology on Wall Street: keeping transaction data private.

Known as a “zero-knowledge proof,” the new code will be included in an Oct. 17 upgrade to the ethereum blockchain, adding a level of encryption that lets trades remain private. Previously, users were able to remain anonymous but transactions were verified by allowing everyone on the network to see them.

“Zero-knowledge proofs are one of the biggest inventions in the last two decades in cryptography,” said Emin Gun Sirer, an associate professor of computer science at Cornell University. It “will allow a slew of applications we can’t even imagine right now.”

Blockchain – the road to mass adoption - BeyondBorders

Blockchain – the road to mass adoption - BeyondBorders | 21st Century Learning and Teaching | Scoop.it
It’s long been argued that blockchain  – the underlying DNA of cryptocurrency Bitcoin – could transform the way financial services companies do business, but how close is it to being used day-to-day?

When it comes to some aspects of the financial services industry, adoption is still a little way off.

There’s no doubt that blockchain’s real-time characteristic and ability to act as a public ledger of all transactions could revolutionise many parts of financial services, reducing risks and bringing cost savings among other benefits.

How blockchain will grow beyond bitcoin

How blockchain will grow beyond bitcoin | 21st Century Learning and Teaching | Scoop.it

 

Since its advent in 2009, bitcoin’s decentralized, broker-less and secure mechanism to send money across the world has steadily risen in popularity and adoption. Of equal — if not greater — importance is the blockchain, the technology that supports the cryptocurrency, the distributed ledger which enables trustless, peer-to-peer exchange of data.

Every day, new companies and organizations, including big names such as Microsoft and Tesla, take strides toward or show interest in using cryptocurrency and blockchain to support their business.

But the fame of blockchain has also given rise to two new challenges, namely that of interoperability and flexibility.

There are now more than a score of blockchain-based currencies, each optimized for different purposes, with different exchange rates, verification and consensus mechanisms, performance, distribution function, block size limit and degree of anonymity. And none of these currencies are compatible with others, making it hard for users to transfer money between them.

5 Real Life Blockchain Implementations Outside of Cryptocurrency

5 Real Life Blockchain Implementations Outside of Cryptocurrency | 21st Century Learning and Teaching | Scoop.it

What do Pied Piper and blockchain tools have in common? Both are always “coming soon.”

By now most of us are familiar with blockchain, the technology underpinning cryptocurrencies like Bitcoin and Ethereum. Outside of cryptocurrency, blockchain has many purported use cases in scenarios that require an immutable ledger.

Rhetoric has elevated blockchain to godly status, labeling it as a bleeding edge technology poised to disrupt all facets of life, from voting, to smart guns, health data, stock trading, international shipping, and beyond.

We’ve seen a ton of other innovative blockchain ideas too, yet many are unproven or simply hypothetical. So, the question is, what projects are successfully implementing blockchain in practice?

In this article we’ll strive to separate fact from fiction by showcasing 5 living projects that are actually using blockchain, with real world results. We’ll gauge the viability of such projects, and see how proven use may affect the global climate and attitude toward blockchain adoption.

Blockchain technology moves into car sharing, mobility services

Blockchain technology moves into car sharing, mobility services | 21st Century Learning and Teaching | Scoop.it
DETROIT (Reuters) - The technology underpinning the cryptocurrency bitcoin is migrating to the auto industry and vehicle sharing.

Accounting and consulting firm EY, part of Ernst & Young Global Ltd, said on Wednesday it was launching a blockchain based system that will enable companies or groups of individuals to more easily share ownership of vehicles and access to cars and trucks. EY could deploy the system, called Tesseract, in a test with an unnamed partner within the next quarter, EY partner John Simlett told Reuters in an interview.

The concept of sharing the use of vehicles is not new to the auto industry, but the use of blockchain technology to record vehicle ownership, log the use of vehicles, and apportion insurance costs and other transactions is in its infancy.

Spaltung: Aus Bitcoin wird Bitcoin und Bitcoin Cash | #CryptoCurrency #ICT

Spaltung: Aus Bitcoin wird Bitcoin und Bitcoin Cash | #CryptoCurrency #ICT | 21st Century Learning and Teaching | Scoop.it
Der heutige 1. August ist ein historischer Tag für die Geschichte der Kryptowährung Bitcoin. Sie spaltet sich in zwei Lager.

 

Die Kryptowährung Bitcoin hat sich am heutigen 1. August in zwei Teile gespalten: Bitcoin und Bitcoin Cash. Die Spaltung wurde offiziell von mehreren Stellen bestätigt.Grund dafür ist eine Aktualisierung des Bitcoin-Protokolls. Bitcoin (BTC), welches seit 2009 existiert, nutzt weiterhin das alte Bitcoin-Protokoll (Blockchain).

 

Das neue Bitcoin Cash (BCC) nutzt dagegen die aktualisierte Variante des Blockchain-Protokolls (Bitcoin ABC). Der sogenannte Hard Fork der Blockchain wird durchgeführt, weil eine Gruppe von Minern, Entwicklern, Investoren und Bitcoin-Nutzern der Aktualisierung des offenen Protokolls zugestimmt hat und diese nun durchsetzen wollen. Das ist möglich, weil es sich eben um ein offenes System handelt, welches keiner Regulierung unterliegt.

 

Der Stärkere und Erfolgreichere gewinnt, lautet hier die Devise.

Wie erfolgreich dieses Vorhaben verlaufen wird, wird die Zeit zeigen. Derzeit ist noch offen, wie viel Rechenleistung Bitcoin ABC erhält. Letztendlich also, wie viel neue Bitcoin Cash über die neuen Clients geschürft werden. Bisher wurde noch kein erster Block für Bitcoin Cash errechnet.

So funktioniert die Blockchain | #ICT  | 21st Century Learning and Teaching | Scoop.it
Was ist eine Blockchain?

Eine der seltenen Definitionen der Blockchain, die mit relativ wenigen Fremdworten auskommt, lautet: „Blockchains sind spezielle Datenbanken, die Transaktionsdaten ohne eine zentrale Kontrollinstanz, ohne die Notwendigkeit gegenseitigen Vertrauens und mit vollkommener Transparenz verwalten können.“

Klingt noch ziemlich abstrakt. Anschaulicher und stark vereinfacht wird die Blockchain vom Techexperten Jamie Skella beschrieben. Sein Blockchain-Artikel ist vor ein paar Wochen bei LinkedIn erschienen und hat sich in Windeseile im Internet verbreitet. Skella sagt, man könne sich eine Blockchain wie ein Kassenbuch vorstellen: Sobald zwischen einem Absender und einem Empfänger eine Datentransaktion stattfindet, wird in das Kassenbuch eine neue Position eingetragen.

Eine der seltenen Definitionen der Blockchain, die mit relativ wenigen Fremdworten auskommt, lautet: „Blockchains sind spezielle Datenbanken, die Transaktionsdaten ohne eine zentrale Kontrollinstanz, ohne die Notwendigkeit gegenseitigen Vertrauens und mit vollkommener Transparenz verwalten können.“

Klingt noch ziemlich abstrakt. Anschaulicher und stark vereinfacht wird die Blockchain vom Techexperten Jamie Skella beschrieben. Sein Blockchain-Artikel ist vor ein paar Wochen bei LinkedIn erschienen und hat sich in Windeseile im Internet verbreitet. Skella sagt, man könne sich eine Blockchain wie ein Kassenbuch vorstellen: Sobald zwischen einem Absender und einem Empfänger eine Datentransaktion stattfindet, wird in das Kassenbuch eine neue Position eingetragen.
