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.

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.

Discussions of blockchain often begin with bitcoin, the cryptocurrency that gained notoriety as much for its novelty as for the volatility of its valuation. In a fog of media reports driven by bitcoin’s associations with dubious use cases,1 the far-reaching potential of blockchain—the technology underpinning bitcoin—remained largely obscured. Yet, that is changing. Organizations throughout the public and private sectors have begun exploring ways that blockchain might profoundly transform some of their most basic operations, from the way they execute contracts and carry out transactions to the ways they engage customers and more.

From 2008 to date, no other technology has been the subject of such fervent debate. Irrespective of your opinion, the rise in popularity of cryptocurrencies cannot be ignored. Today, there are a number of billion dollar businesses that accept Bitcoin as a form of payment. These include Dell, Reddit, Expedia, PayPal, and most recently, Microsoft.… Learn more / En savoir plus / Mehr erfahren: http://www.scoop.it/t/21st-century-learning-and-teaching/?tag=blockchain

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.

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.

No central authority
Blockchain has been hailed by admirers as holding the revolutionary promise that the internet did two decades ago. Business figures from Microsoft’s Bill Gates to Richard Branson, the founder of the Virgin Group, have extolled its potential; on a trade mission to Asia in August, David Cameron, the UK prime minister, included a blockchain expert among his entourage.

BTC’s cutting edge patent pending election system process uses the blockchain for an extra level of security not found in any other voting solution. Because blockchain-based records are time-stamped and signed, post-election fraud is rendered virtually impossible. The voting process begins with tried and true paper ballots. This removes any voter confusion about how to properly vote and ensures that from the onset there is an indisputable audit trail, as physical paper ballots remain the ultimate document of record.
