Blockchain beyond Bitcoin

Published

on

Distributed ledger technology like blockchain was only associated to the financial services until recently. However, companies in other industries are starting to understand its power, write MARY ANN FRANCIS and GILLES GRAVIER of Wipro.

Distributed ledger technology has, so far, been largely discussed only in the context of the financial services industry, specifically in the area of payments. Blockchain technology was popularised by its application in the wildly-popular new crypto-currency Bitcoin, for example.

But blockchain has many wondrous applications in a variety of other industries as well; where visionary firms are starting to understand its power to transform their operations.

Essentially, blockchain allows for the creation of timestamped digital assets, and digital records, which are impossible to tamper with, delete, or edit, commonly referred to as immutable.

So, for a vastly different scenario than moving currencies – imagine a diamond producer leveraging holographic identity technology, where a record of all transactions could be connected to this holograph, and entered into a blockchain. Consumers could see the public record of all prior transactions, and get assurance that the diamond was sourced ethically.

Following the same principles, a blockchain could be used by fine art distributors to confirm the validity of its pieces, or by lawyers to validate the accuracy of photo and video evidence, or by governments when issuing title deeds to homeowners.

The possibilities are endless. There are already companies, start-ups, offering products that cover these specific use cases.

Transparency and efficiency

As a distributed ledger, blockchain technology presents companies with an opportunity to fundamentally re-architect many of its internal processes, and the ways in which they interact with partners, suppliers, distributors, and others in the varied ecosystem.

Whether the use-case is smart-contracts, cryptocurrencies, proof-of-assets, or anything else that blockchains enable, companies are able to interact in a more collaborative, but highly-secure, trusted, manner.

But many CEOs remain reticent to seriously look at adopting blockchain technologies into the company’s business strategies. And it’s true that this area of technology seems to be moving at a rapid pace – zooming into mainstream conversations on the back of Bitcoin and other virtual currencies. To some, blockchain looks volatile, uncertain, risky.

However, blockchain technology can be applied to businesses in South Africa, to improvise record management and transactional efficiency in a wide range of different processes and value chains.

So just how quickly could blockchains take off in SA, considering the very many possibilities for the technology? At this year’s Gartner Symposium/ITxpo Africa, held in late-September in Cape Town, conference delegates showed overwhelming interest in its use.

From keynotes to sideline discussions, the enthusiasm for blockchain technology was palpable, making analysts more bullish on the prospects for blockchain in the short-term. Very possibly, the technology could grip the imaginations of business in a similar way to the Cloud revolution, for instance.

Getting started

The best starting point is to research blockchain deeply and widely, understanding potential use-cases for your industry; and then looking at which internal processes and external transactions could potentially be improved. Which areas would benefit from greater transparency, greater collaboration?

Every company is different. Some rely more heavily on digital assets and services than others, others have embraced connected sensors and devices (the “Internet of Things”) more warmly than others, and some naturally have a more innovative leaning.

But in our experience there are exciting blockchain-related opportunities in even the most traditional organisations.

Following this discovery phase, it is critical to partner with an objective blockchain specialist that can help to craft the strategy. Firms that try to ‘rate their own work’ in this field often miss opportunities, or create blockchain plans that fail to respond to the most urgent business priorities. As we find ourselves in the top of the hype-cycle for blockchain, we still find ourselves in search of the app that brings maximum ROI.

It is recommended that businesses look for three key competencies in a blockchain partner:

•             Thought-leading advisory and consulting services with the ability to design, implement and support blockchain initiatives, along with rich domain expertise in use cases across various industry verticals

•             A deep pool of partners, start-ups and innovators with whom solutions can be created and tailored to the organisation’s unique needs

•             The execution capability to actually run blockchain PoCs and evolve them into fully-fledged solutions – integrating the technology into existing operations.

With blockchain, the traditional principles governing ‘systems of record’ are fundamentally reversed, and many business leaders are still somewhat confused about how this highly-sophisticated shared ledger technology actually works.

But while it’s essential to read deeply and understand blockchain principles, for one’s end-client, we can refer to the analogy of the internet to explain why we don’t have to wait for clients wrap their heads around the technology.

Most of us do not understand the technicalities of the TCP/IP protocol, but that doesn’t hinder us from surfing the web and exchanging emails. In the same way, clients will come to trust blockchain, in the same way they trust the Internet.

Those organisations starting now on a blockchain journey will have a first-mover advantage over slower-moving peers, getting a jump start on the competition and repositioning themselves for a future where blockchains govern all sorts of interactions and transactions in the future. Scale use of blockchain is still a 3-5-year journey – starting now will lessen the urgency some are experiencing now.

Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Published

on

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

How Africa can embrace AI

Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.

To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.

These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.

Staying ahead of the trends to stay employed

AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.

According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.

It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.

Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.

It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.

Combining STEM with the arts

Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Revisiting laws and regulation

For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.

Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.

Preparing for the future

With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.

To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.

It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
