Stupid About — Blockchain

A Smart Guide to the Emerging Technology Wilderness: 1.01

The rules of blockchain:

Rule #1 — You probably don’t need blockchain

Rule #2 — You probably won’t be able to live without blockchain

Rule #3 — By the time you need blockchain, you won’t know you’re using blockchain

I once had to brief the leaders of a large enterprise on “this blockchain thing.” Their customers were asking about it, and they needed answers. I spent hours with them. They managed to figure out how to spell it, but they weren’t getting it. I don’t think they ever really did. How “stupid,” right?

But here’s the thing. Those leaders are wickedly smart about getting 200,000 people to work together without running amok. They are smarter about that subject than I may ever be. (Not ruling it out.) Weiterlesen

Blockchain 2.0

Cryptocurrencies are only the beginning

Launching the Credit Suisse Blockchain Revolution Series: In this in-depth report, we analyse the market implications of blockchain technology in light of the bitcoin boom since our initial cross-sector and cross-border publication, Blockchain: The Trust Disrupter, roughly a year ago. While we make no comment on the valuation of particular cryptocurrencies, we believe the rise of bitcoin and Initial Coin Offerings highlights how transformative the underpinning blockchain technology will be across sectors, with financial services and capital markets at the front of the queue.

Various blockchain projects we discussed in our previous report are arriving at preliminary conclusions, transitioning from Proof of Concept to Pilot and even Production phases of development. To contextualise these over the medium to long term, we once again deliver a collaborative analysis of the following:

Cryptocurrencies and ICOs: Crucially, we see these providing momentum for further blockchain development, even if bitcoin and Initial Coin Offerings continue to encounter challenges to widespread adoption.

Blockchain’s utility: We examine the key advances and diversification of the applications that sit atop blockchain platforms – as well as the theoretical risks to blockchain itself. We also show project timelines to illustrate current and future positioning on the blockchain landscape.

Market implications: Contributions from 23 analysts across three geographies provide us with a cross-sector blockchain window through which we examine the Payments, Security, Banks, Exchanges, Business Services, Leisure, and Real Estate sectors.

Featured stocks include Sophos (Outperform; CS European SMID Focus List), Square (Neutral), LSE (Outperform; CS European Focus List), ASX (Underperform), Equiniti (Underperform), Experian (Outperform; CS European Focus List) and Playtech (Outperform).

The United Arab Emirates is ramping up blockchain development in a bid to become, by 2020, a leading center for innovation and the first government in the world to execute all of its transactions on a blockchain.

The move seeks to cut an estimated 100 million paper transactions annually and reduce the 25 million hours of work required in handling paper documents in Dubai alone.

Sheikh Hamdan Bin Mohammed Bin Rashid Al Maktoum, Dubai Crown Prince, launched the Dubai Blockchain strategy in October, which aims at achieving a high degree of efficiency in government departments.

Another area of the strategy seeks to create thousands of new jobs by leveraging blockchain technology to allow Emiratis, expatriates and investors to set up companies more easily.

„The strategy will result in substantial economic saving that can be reinvested in value-added sectors and will contribute to saving millions of hours wasted in entering data and ensuring their veracity,“ said Mohammad Abdullah Al Gergawi, Vice Chairman of the Board of Trustees and Managing Director of Dubai Future Foundation.

„It will also create new economic fields and businesses as the volume of blockchain market is expected to hit US$300 million over the course of the next five years.”

The strategy is a joint project between the government’s Dubai Future Foundation and Dubai Smart City Office.

Earlier this year, the Dubai Future Foundation launched the Global Blockchain Council, a public-private initiative that demonstrated the UAE’s commitment to the technology.

Under the Global Blockchain Council umbrella, prominent financial institutions, technology firms and startups are collaborating on a number of pilot projects that promise to increase efficiency in processes, cut costs and create new business opportunities. Among these projects, a system called BitOasis aims at creating a blockchain platform „to secure [the] flexidesk contracts and registration process.“ Another project, called the Kraken Bitcoin Exchange, seeks to build a financial infrastructure for Islamic finance operations. Both pilot projects are being overseen by Dubai Multi Commodities Center Authority.

Dubai Future Accelerators Selects Two Blockchain Companies for Pilot Programs

In September, Dubai Future Foundation kicked off the inaugural Dubai Future Accelerators, a 12-week program that seeks to connect international technology startups with government entities to create prototypes and pilots for the city of Dubai.

More specifically, Dubai Future Accelerators paired 30 companies with seven of Dubai’s public services: Health, Energy, Knowledge, Municipality, Police, Transport and the investment portfolio, Dubai Holding.

The program, which ended earlier this week, selected 19 out of the 30 companies to move forward to the pilot and prototyping phase. These will receive a total of Dh120 million (US$32.6 million) in investment.

Of the participating companies, 14 have already relocated their headquarters to Dubai, highlighting the city’s growing attractiveness.

“The UAE has become the foremost global platform for turning the future into reality,” said His Excellency, Mohammed Al Gergawi, Minister of Cabinet Affairs and The Future, and Vice Chairman of the Dubai Future Accelerators. “It is the ideal destination to materialize innovative ideas into tangible projects that have a significant impact on the economy and society — projects that can create better lives for us and for future generations.”

Among the companies that made it to the next phase, Loyyal, a loyalty and rewards platform, signed a deal with Dubai Holding for a pilot deployment aimed at creating the „internet of loyalty points, promotions and rewards“ by using blockchain technology. Specifically, it will seek to provide an innovative and cost effective solution to enhance and connect different loyalty programs.

The pilot will focus on the Jumeirah Group and TECOM Group, Dubai Holding’s sister company, bringing together their respective loyalty schemes to enable network-effect opportunities.

„We established the Global Blockchain Council here in Dubai less than a year ago, and are already seeing impressive advancements in the uptake of this technology,“ commented Saif Al-Aleeli, CEO of the Dubai Future Foundation and Founding Member of the Global Blockchain Council. „We are pleased by Loyyal’s progress with Dubai Points, their partnerships with the private sector, and look forward to working even closer with them as they bring the blockchain future to reality.“

As part of the deal, Loyyal will be deploying its proprietary and patent-pending blockchain and smart contract infrastructure solution to re-map the way Dubai Holding’s businesses interact with consumers and each other.

Alongside Loyyal, other blockchain startups that were selected for program integration included BlockApps, an Ethereum compliant platform for the development, deployment and management of enterprise blockchain applications, and ConsenSys. The largest Ethereum blockchain software company in the world, ConsenSys, will develop a real estate database using blockchain technology for the pilot program.

The 19 pilot projects are expected to create 135 job opportunities in Dubai over the next three months, which is projected to increase exponentially when the projects achieve tangible results, and the companies expand their activities.

The second round of the Dubai Future Accelerator program will kick off in the beginning of Q1 2017 and will see five additional government and private entities joining in: the Department of Economic Development, Dubai Smart Office, the General Directorate of Residency and Foreigners Affairs, Etisalat and du, both telecom operators in the UAE.

Some financial gurus are convinced that blockchain (the underlying tech behind bitcoin) is the future of business, and they might already have some proof. The Commonwealth Bank of Australia and Wells Fargo have conducted the first international, inter-bank trade deal to use blockchain for the transaction. It was a relatively modest experiment that shipped $35,000 in cotton from Texas to China, but it demonstrated the advantages of taking humans out of the equation. The deal included smart contracts that automatically sent payments and transferred ownership as the cargo reached certain locations. The companies involved didn’t have to waste time sending documents, processing money or worrying about potential fraud.

Don’t expect blockchain to be a mainstay of trade in the near future. Wells Fargo tells the Sydney Morning Herald that there are „significant regulatory, legal and other concerns“ that have to be resolved before it’s used on a regular basis. However, the advantages make it hard to ignore. Existing shipping processes can take days, especially for cross-continent trips where time zones are a major factor. Blockchain reduces the transaction time to minutes — cargo could arrive much sooner, which means less time waiting for the products you want to buy.

Das Europäische Parlament hat am Donnerstag mit 542 Ja-Stimmen, 51 Gegenstimmen und 11 Enthaltungen den Bericht zu virtuellen Währungen und Blockchain, der zugrundliegenden Technologie, angenommen.

Zunächst: keine großen Überraschungen, hervorzuheben ist m.E. dieser Punkt 4:

…dass eine verfrühte Regulierung in dieser sich noch im Wandel befindlichen Situation möglicherweise nicht angebracht ist, da sie der Öffentlichkeit in Bezug auf die Vorteile oder die Sicherheit virtueller Währungen ein falsches Bild vermitteln könnte

Schön, dass hier zunächst die Dynamik innerhalb der Blockchain-Welt unbeeinflusst bleiben soll und die Vorzüge der Crypto-Currencies per se zunächst klar erkannt werden. Eine spätere Regulierung vor allem unter Geldwäsche und Terrorismusfinanzierungs-Gesichtspunkten macht allerdings absolut Sinn.

Es ist ähnlich wie mit dem Internet vor 20 Jahren: Das ganze Potential virtueller Währungen und der zugrundeliegenden Technologie lässt sich heute höchstens erahnen. In diesem frühen Stadium setzen wir auf intensive Beobachtung und Überwachung der Entwicklungen statt zu frühe Detailregulierung. So können sich Innovationen entwickeln, während der Staat die Risiken im Blick behält

unterstreicht der SPD-Europaabgeordnete Jakob von WEIZSÄCKER, Berichterstatter im Parlament.
