How Blockchain can save water, and more

Published

on

The designers of a unique water saving solution that uses blockchain technology to incentivise users to use less water were the winners of a special prize at the continent’s largest blockchain hackathon held in Cape Town last week.

The Unlock The Block hackathon was hosted by Linum Labs and the African Institute of Financial Markets And Risk Management (AIFMRM) and culminated in Cape Town’s first ever Blockchain Symposium.  Almost 80 participants from around the world attended.

The special prize was awarded to project SudoTesla, designed to transfer water tokens via the Ethereum network to a smart meter. The tokens are allocated by the designated utility and users are compensated for water that they save.

The special prize awarded the team, led by Michael Sanne of South Africa, included a month at Absa’s Rise facilities at the Woodstock Exchange in order to further develop their project. Sanne said he hoped it would be possible to bring such a project to fruition one day, even if it was challenging. “Water is a scarce resource, and this solution aims to help manage that resource”, he said.

The overall first prize was split between two teams: the first being BlockPoll, who built a blockchain voting system facilitating better governance in companies, as well as transparency and security in elections. Judge Co-Pierre Georg, Associate Professor at AIFMRM, described their solution as “incredibly slick”.

BlockPoll’s team, consisting of WhenMoon?’s Brandon Kenley Verkerk, Christopher Maree, Iordan Tchaparov and Kavilan Nair, say the design’s main advantages are that it’s decentralised, immutable, and easily auditable. Moreover, they add, it’s easy to use, secure, and open source.

The other winning team was Proof of Steak by Yuna, which Georg described as “a really awesome tech solution to a true African issue”.  The team, consisting of Kungela Mzuku, Kyle Roos and Una Singo, allows farmers to use their cattle as collateral on a block-chain, enabling peer-to-peer lending. The team described this as a “uniquely African” and “contextual approach” which would “allow anyone in the world to invest in your cow”. Farmers register their cattle on the blockchain, which functions as an immutable ledger, and investors provide funding to the farmer.

A further special prize for innovation was awarded to team EWAN from Berlin, who built a curation market application.

Prior to the event, Linum Labs’ Devon Krantz said beyond the immediate value of cryptocurrencies, blockchain technology held great potential for “changing systems that already exist”.

“The event has shown us two things, firstly that the applications of blockchain technology in improving people’s lives in Africa are immense and second, it is much easier to build those applications than many people think – we just need to work together,” added Paul Kohlhaas, Founder of Linum Labs.

“This is a historic moment in time,” Georg said at the event. “Our economy will soon embark on a fourth industrial revolution.” Economic leadership would lie in the provision of scarce skills, he said. “There is therefore a need to think outside the box. Something clicked in our minds. This led to the hackathon.” Collaborations and partnerships of this kind, he added, would continue to address the need for scarce skills.

The Unlock the Block blockchain Hackathon was a 10-day long event during which participants learned some of these scarce skills, including how to develop blockchain applications. The first five days were dedicated to a digital “boot camp”, during which participants were exposed to overarching fintech trends and the blockchain tools needed to develop decentralised applications and protocols. Topics covered included Bitcoin, Ethereum and other cryptocurrencies, and sessions were led by industry experts.

At the end of the hackathon, participants were given three days to develop their own blockchain application. The Symposium occurred on the final day.

The Hackathon was sponsored by both South African and international businesses, including Absa, Microsoft, Old Mutual, Status, Foundery, Consensys, Citi, Pick ‘n Pay, UCT and Rise.

How we use phones to avoid human contact

A recent study by Kaspersky Lab has found that 75% of people pick up their connected device to avoid conversing with another human being.

Connected devices are becoming essential to keeping people in contact with each other, but for many they are also a much-needed comfort blanket in a variety of social situations when they do not want to interact with others. A recent survey from Kaspersky Lab has confirmed this trend in behaviour after three-quarters of people (75%) admitted they use a device to pretend to be busy when they don’t want to talk to someone else, showing the importance of keeping connected devices protected under all circumstances. 

Imagine you’ve arrived at a bar and you’re waiting for your date. The bar is busy, and people are chatting all around you. What do you do now? Strike up a conversation with someone you don’t know? Grab your phone from your pocket or handbag until your date arrives to keep yourself busy? Why talk to humans or even make eye-contact with someone else when you can stare at your connected device instead?

The truth is, our use of devices is making it much easier to avoid small talk or even be polite to those around us, and new Kaspersky Lab research has found that 72% of people use one when they do not know what to do in a social situation. They are also the ‘go-to’ distraction for people even when they aren’t trying to look busy or avoid someone’s eye. 46% of people admit to using a device just to kill time every day and 44% use it as a daily distraction.

In addition to just being a distraction, devices are also a lifeline to those who would rather not talk directly to another person in day-to-day situations, to complete essential tasks. In fact, nearly a third (31%) of people would prefer to carry out tasks such as ordering a taxi or finding directions to where they need to go via a website and an app, because they find it an easier experience than speaking with another person.

Whether they are helping us avoid direct contact or filling a void in our daily lives, our constant reliance on devices has become a cause for panic when they become unusable. A third (34%) of people worry that they will not be able to entertain themselves if they cannot access a connected device. 12% are even concerned that they won’t be able to pretend to be busy if their device is out of action.

Dmitry Aleshin, VP for Product Marketing, Kaspersky Lab said, “The reliance on connected devices is impacting us in more ways than we could have ever expected. There is no doubt that being connected gives us the freedom to make modern life easier, but devices are also vital to help people get through different and difficult social situations. No matter what your ‘connection crutch’ is, it is essential to make sure your device is online and available when you need it most.”

To ensure your device lifeline is always there and in top health – no matter what the reason or situation – Kaspersky Security Cloud keeps your connection safe and secure:

·         I want to use my device while waiting for a friend – is it secure to access the bar’s Wi-Fi?

With Kaspersky Security Cloud, devices are protected against network threats, even if the user needs to use insecure public Wi-Fi hotspots. This is done through transferring data via an encrypted channel to ensure personal data safety, so users’ devices are protected on any connection.

·         Oh no! I’m bored but my phone’s battery is getting low – what am I going to do?

Users can track their battery level thanks to a countdown of how many minutes are left until their device shuts down in the Kaspersky Security Cloud interface. There is also a wide-range of portable power supplies available to keep device batteries charged while on-the-go.

·         I’ve lost my phone! How will I keep myself entertained now?

Should the unthinkable happen and you lose or have your phone stolen, Kaspersky Security Cloud can track and protect your device from data breaches, for complete peace of mind. Remote lock and locate features ensure your device remains secure until you are reunited.

Five key biometric facts

Due to their uniqueness, fingerprints are being used more and more to quickly identify and ensure the security of customers. CLAUDE LANGLEY, Regional Sales Manager, for Africa at HID Global Biometrics, outlines five facts about the technology.

Published

How many times in a day are you expected to identify yourself? From when you arrive at work you are required to sign in, visiting your bank, receiving healthcare services… The list is endless. When a system knows who you are, you are able to do any number common, everyday activities. Your identity is unique and precious. It is also easily stolen and the target of many hackers across the globe. Technology is constantly evolving alongside the criminal element, always looking for ways to protect data and identity. One such solution happens to be biometrics and it is rapidly gaining traction in our increasingly complex modern world.

Reliable, secure and fundamentally YOU, unique biometric traits such as fingerprints are being used by banks, enterprises and consumers to verify identity. Biometric solutions offer significant identity protection because they use unique biological details to ensure an account is only accessed by the account holder, a door only opened by the owner. Here are five things that are little known about this technology…

  • The uncut identity. Your fingerprint is unique to you. Nobody can use a copy of it to impersonate you. Good technology is capable of scanning down into the layers of the fingertip to differentiate unique elements of a person’s fingerprint, this data is then encrypted and used as a key to unlocking whichever physical or virtual door that the biometric system protects.
  • The living proof. No, there is nothing to the stories of fingerprints being used without their owner’s knowledge or permission. Biometric solutions can use specific variables to determine if the finger used to access the system is that of a present, living person.  A copy or a fake cannot be used to access a cutting-edge biometric solution.
  • Easy and convenient. Queues and documents and paperwork may well be a thing of the past should biometrics take a firmer grip of government and banking systems. The process of registering is easy, and access to identity documents and records is yours alone.
  • Security blanket. A thousand passwords and a hundred post-it notes stuck on walls and drawers.  An excel file with a list of sites and applications and their corresponding passwords, all a thing of the past.  Nobody needs to remember their password with biometrics, they only need to show up.
  • Anywhere is cool. Schools, airports, networks, offices, homes, toilets, banks, libraries, governments, border controls, immigration services, call centres, hospitals and even clubs and pubs – knowing “who” matters and biometrics can quickly and conveniently confirm your identity where needed.
