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.

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

Buy 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

Pizoelectrics: Healthcare’s new gymnasts of gadgetry

Published

on

Healthcare electronics is rapidly deploying for wellness, electroceuticals, and intrusive medical procedures, among other, powered by new technologies. Much of it is trending to diagnostics and treatment on the move, and removing the need for the patient to perform procedures on time. 

Instruments become wearables, including electronic skin patches and implants. The IDTechEx Research report, “Piezoelectric Harvesting and Sensing for Healthcare 2019-2029”, notes that sensors should preferably be self-powered, non-poisonous even on disposal, and many need to be biocompatible and even biodegradable. 

We need to detect biology, vibration, force, acceleration, stress and linear movement and do imaging. Devices must reject bacteria and be useful in wearables and Internet of Things nodes. Preferably we must move to one device performing multiple tasks. 

So is there a gymnast material category that has that awesome versatility? 

Piezoelectrics has a good claim. It measures all those parameters. That even includes biosensors where the piezo senses the swelling of a biomolecule recognizing a target analyte. The most important form of self-powered (one material, two functions) piezo sensing is ultrasound imaging, a market growing at 5.1% yearly. 

The IDTechEx Research report looks at what comes next, based on global travel and interviewing by its PhD level analysts in 2018 with continuous updates.
