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.

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.

Die Blockchain wird meist in Verbindung mit Bitcoins gebracht. Ganz falsch ist der Zusammenhang auch gar nicht. Zwar ist die Anwendung der Blockchain-Methode generell auch in anderen Bereichen möglich, in einer offenen Blockchain erfolgt die Validierung jedoch grundsätzlich durch das sogenannte „Mining“. Und das wiederum ist nur mit Bitcoins möglich, da sich der nicht unerhebliche Validierungsaufwand für potenzielle Miner schlicht nur durch die anteilige Entlohnung durch Bitcoins lohnt. Gratis würde wohl kaum jemand seinen Rechner und die entsprechende Rechenleistung zur Verfügung stellen.
Lediglich in geschlossenen Systemen, etwa zwischen Banken gibt es auch andere Validierungsmethoden. Gerade Banken betreiben aktive Forschungen auf dem Gebiet der Blockchain.
Besonders nützlich für die Geldinstitute ist ein geschlossenes System etwa bei der Übertragung von Wertpapieren zwischen den verschiedenen Häusern. Das die Blockchain auf längere Sicht also die Banken abschaffen wird, stimmt deshalb nicht.
Das mag vielleicht auch daran liegen, dass für die Blockchain-Technologie ein relativ fundiertes Wissen benötigt wird. Die Methode kann also, zumindest zum aktuellen Zeitpunkt, mit Nichten von jedermann verwendet werden. Auch Experten gibt es auf diesem Gebiet noch sehr wenige.

The Blockchain Futures Lab at Institute for the Future is a research initiative and a community for identifying the opportunities and limits of blockchain technologies as well as their social, economic, and political impacts on individuals, organizations, and communities over the coming decades. The program brings together the leading developers of blockchain tools and applications with organizations that seek to understand the implications of this highly disruptive technology—and perhaps also to create parts of the new ecosystem of infrastructures and markets that it will drive.

Unless you’ve been hiding under a rock, I’m sure you’ve heard of Bitcoin and blockchain. After all, they are one of the most trending topics these days — the ultimate buzzwords of the year. Even people who’ve never mined cryptocurrency or understand how it works, are talking about it.

Kim Jong Un und Donald Trump spielen derzeit buchstäblich mit dem Feuer. Der Schlagabtausch der beiden Atomnationen schreckt auch die Finanzmärkte auf und sorgt dafür, dass krisenfeste Währungen einen wahren Boom erleben. Allen voran das Kryptogeld Bitcoin, dessen Kurs innerhalb eines Jahres um 600 Prozent zunimmt. Auch andernorts wird fleißig in das virtuelle Zahlmittel investiert.

Bitcoin Cash, a tweaked version of the digital currency created by one side in an industry rift, started trading Tuesday. If it wants to be bitcoin’s equal, it is about 10% of the way there.
Most digital currency exchanges and services at this point aren’t supporting Bitcoin Cash. One exchange that is, China-based ViaBTC, has been allowing trading in the coin even before it goes live. On that basis, Bitcoin Cash was most recently trading at about 11% of a bitcoin’s value, roughly in line with traders’ projections in the days leading up to the launch.
With the original bitcoin trading at around $2,750, Bitcoin Cash was worth around $300. Another virtual currency tracker, Coinmarket.com, showed Bitcoin Cash falling to about $242 from a high of about $400 in volatile trading.

La dynamique vient principalement de Chine, mais a des conséquences mondiales : pour la première fois la valeur du Bitcoin a dépassé cette semaine celle de l'once d'or. Les chinois fuient le yuan pour le Bitcoin, ce qui fait exploser son cours. L'or irrite la soif de l'or, et ne l'étanche pas" disait-on au premier siècle avant notre ère à Rome. Mais ça, c'était avant le Bitcoin, monnaie numérique apparue en 2009. Hier jeudi, la valeur de sa crypto monnaie a pour la première fois dépassée celle de l'once d'or. Une unité du Bitcoin valait alors 1 268 dollars tandis qu’une once d’or était estimée à 1 233 dollars. Bref, la soif de Bitcoin devient plus importante que la soif de l'or.

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.

According to a recent study by Accenture, investments in fintech hit $5.3 billion in the first quarter of this year (having grown 75 percent in 2015, exceeding $22 billion). These are staggering figures for a still nascent industry, which can have a monumental impact on all sectors, from lending and investments to savings and payments.
Hitherto, most of the investments have occurred in the U.S. and Europe, with a marked exception this year when China’s Ant Financial completed a staggering $4.5 billion raise at a $60 billion valuation, making it one of the highest-valued private companies in the world.
This recent raise may draw to emerging markets attention from the world beyond London, New York and Silicon Valley, which importantly house more than 90 percent of the world’s under-30 population. Countries other than the U.S. and U.K. have collectively spawned a range of visibly successful companies in search (Yandex, Baidu), e-commerce (Alibaba, Rocket Internet’s portfolio) and media (Naspers) by mostly applying tried and tested Western strategies to the local know-how.

The global finance markets are slipping on Friday after the UK public voted to leave the EU, but there is one currency that is reveling in the uncertainty of the Brexit result: bitcoin.
The cryptocurrency is notoriously difficult to predict. Its price against the U.S. Dollar rose as high as $1,000 in 2013 and, while it has stabilized somewhat since that landmark valuation, it hit a two-and-a-half year high of nearly $775 on June 17 before cratering nearly 25 percent over the next week.
That drop was thought by some be related to the British referendum on continued EU membership, but once the result was clear — with multiple media calling it a win for the Leave campaign — bitcoin grew legs and jumped past $650 just one day after it was at $550, according to data from Coindesk.

If the blockchain frenzy and the hype surrounding it is anything to go by, blockchain is set to revolutionise everything from the way in which we make payments to the way in which we drink beer. I may have made that last bit up – but you get the idea that in and amongst the buzz there are some pretty wild predictions being made! So in this post, i thought it would be useful to take a step back from the hype and understand “what is blockchain?” If you keep coming back to this fundamental question, i think it can help you navigate and understand what use cases are feasible and which ones are not. Through these 6 awesome infographics we get a good understanding of what blockchain is: Learn more / En savoir plus / Mehr erfahren: http://www.scoop.it/t/luxembourg-europe/?tag=Blockchain http://www.scoop.it/t/luxembourg-europe/?tag=Bitcoin http://www.scoop.it/t/21st-century-learning-and-teaching/?tag=blockchain

When you hear the word blockchain does it make your head spin? Wall Street analysts and fintech experts claim it could make traditional banking obsolete; Airbnb just acquired a team of blockchain experts; and the country of Estonia will use it to secure a million patient health records.
But what exactly is blockchain, and what are its implications for higher education?
Originally created as the underlying database for bitcoin (the peer-to-peer digital asset and payment system), blockchain’s technology is now being seen as valuable and purposeful beyond the financial sector. The advantages blockchain provides to store information on a secure, permanent, historical ledger that can be both public and private will change how edtech applications approach student data.
