I’m always on the lookout for something that helps make blockchain and cryptocurrency more understandable. (For the uninitiated or anyone like me who needed to refresh their memories, I have links to good essays on the topic further down in this posting.)
A kit made from everyday objects is bringing the blockchain into the physical world.
The ‘BlocKit’, which includes items such as plastic tubs, clay discs, padlocks, envelopes, sticky notes and battery-powered candles, is aimed to help people understand how digital blockchains work and can also be used by innovators designing new systems and services around blockchain.
A team of computer scientists from Lancaster University, the University of Edinburgh in the UK, and the Universiti Teknologi MARA, in Malaysia, created the prototype BlocKit because blockchain — the decentralised digital infrastructure that is used to organise the cryptocurrency Bitcoin and holds promise to revolutionise many other sectors from finance, supply-chain and healthcare — is so difficult for people to comprehend.
“Despite growing interest in its potential, the blockchain is so novel, disruptive and complex, it is hard for most people to understand how these systems work,” said Professor Corina Sas of Lancaster University’s School of Computing and Communications. “We have created a prototype kit consisting of physical objects that fulfil the roles of different parts of the blockchain. The kit really helps people visualise the different component parts of blockchain, and how they all interact.
“Having tangible physical objects, such as a transparent plastic box for a Bitcoin wallet, clay discs for Bitcoins, padlocks for passwords and candles representing miners’ computational power, makes thinking around processes and systems much easier to comprehend.”
The BlocKit consisted of physical items that represented 11 key aspects of blockchain infrastructure and it was used to explore key characteristics of blockchain, such as trust – an important challenge for Bitcoin users. The kit was evaluated as part of a study involving 15 experienced Bitcoin users.
“We received very positive feedback from the people who used the kit in our study and, interestingly, we found that the BlocKit can also be used by designers looking to develop new services based around blockchain – such as managing patients’ health records for example.”
I will be providing a link to and a citation for the paper but first, I’m excerpting a few bits,
We report on a workshop with 15 bitcoin experts, [emphasis mine] 12 males, 3 females, (mean age 29, range 21-39). All participants had at least 2 years of engaging in bitcoin transactions: 9 had between 2 and 3 years, 4 had between 4 and 5 years, 2had more than 6 years. All participants have at least graduate education, i.e., 6 BSc, 7 MScs, and 2 Ph.D. Participants were recruited through the mailing lists of two universities,and through a local Bitcoins meetup group. [p. 3]
A striking finding was the overwhelmingly positive experience supported by BlocKit. Findings show that 10 participants deeply enjoyed physically touching [emphasis mine] its objects and enacting their movement in space while talking about blockchain processes: “there is going to be other transactions from other people essentially, so let’s put a few bitcoins in that box. I love this stuff, this is amazing” [P12]. Participants suggested that BlocKit could be a valuable tool for learning about blockchain: “I think this all makes sense and would be fine to explain to the novices. It is cool, this is really an interesting kit”[P7]. Other participants suggested leveraging gamification principles for learning about blockchain: “It’s almost like you could turn this into some kind of cool game like a monopoly”[P5] [p. 5]
A significant finding is the value of the kit in supporting experts to materialize and reflect on their understanding of blockchain infrastructure and its inner working. We argue that through its materiality, the kit allows bringing the mental models into question, which in turn helps experts confirm their understandings, develop more nuanced understandings, or even revise some previously held, less accurate assumptions. [emphasis mine]
Even experts are still learning about bitcoin and blockchain according to this research sample. it’s also interesting to note that the workshop participants enjoyed the physicality. I don’t see too many mentions of it in my wanderings but I can’t help wondering if all this digitization is going to leave people starved for touch.
Getting back to blockchain, here’s the link and citation I promised,
Introductory essays for blockchain and cryptocurrency
Here are two of my favourites. First, there’s this February 6, 2018 essay (part ii of a series) by Tim Schneider on artnet.com explaining it all by using the art world and art market as examples,
… the fraught relationship between art and value lies at the molten core of several pieces made using blockchain technology. Part one of this series addressed how, in theory, the blockchain strengthens the markets for new media by introducing the concept of digital scarcity. This innovation means that works as simple as an “original” JPG or GIF could be made as rare as Francis Bacon paintings. (This fact leads to a host of business implications that will be covered in Part III.
However, a handful of forward-looking artists is using the blockchain to do more than reset the market’s perception of supply and demand. The technology, their work proves, is more than new software—it’s also a new medium.
The description of how artists using blockchain as a medium provides some of the best descriptions of cryptocurrency and blockchain that I’ve been able to find.
The other essay, a January 5, 2018 article for Slate.com by Joshua Oliver, provides some detail I haven’t seen anywhere else (Note: A link has been removed),
Already, blockchain has been hailed as likely to revolutionize … well … everything. Banks, health care, voting, supply chains, fantasy football, Airbnb, coffee: Nothing is beyond the hypothetical reach of blockchain as a revolutionary force. These predictions are easy to sell because blockchain is still little-understood. If you don’t quite know what blockchain is, it’s easier to imagine that it is whatever you want it to be. But before we can begin to search for the real potential amid the mass of blockchain conjecture and hype, we need to clear up what exactly we mean when we say blockchain.
One cause of confusion is the phrase the blockchain, which makes it sound like blockchain is one specific thing. In reality, the word blockchain is commonly used to describe two broad types of computer systems. [emphases mine] Both use similar underlying protocols, but they have other important differences. Bitcoin represents one approach to using blockchain, one wedded to principles of radical decentralization. The second approach—pioneered by more business-minded players—puts blockchain to use without adopting bitcoin’s revolutionary, decentralized governance. Both of these designs are short-handed as blockchains, so it’s easy to miss the crucial differences. Without grasping these differences, it’s hard to understand where we are today in the development of this promising technology, which blockchain ventures are worth your attention, and what might happen next.
I’m not a big fan of DNA (deoxyribonucleic acid) companies that promise to tell you about your ancestors and, depending on the kit, predisposition to certain health issues as per their reports about your genetic code. (I regularly pray no one in my family has decided to pay one of these companies to analyze their spit.)
During Christmas season 2018, the DNA companies (23andMe and Ancestry) advertised special prices so you could gift someone in your family with a kit. All this corporate largesse may not be wholly in service of the Christmas spirit. After all, there’s money to be made once they’ve gotten your sample.
Monetizing your DNA in 2016
I don’t know when 23andMe started selling DNA information or if any similar company predated their efforts but this June 21, 2016 article by Antonio Regalado for MIT (Massachusetts Institute of Technology) Review offers the earliest information I found,
“Welcome to You.” So says the genetic test kit that 23andMe will send to your home. Pay $199, spit in a tube, and several weeks later you’ll get a peek into your DNA. Have you got the gene for blond hair? Which of 36 disease risks could you pass to a child?
Run by entrepreneur Anne Wojcicki, the ex-wife of Google founder Sergey Brin, and until last year housed alongside the Googleplex, the company created a test that has been attacked by regulators and embraced by a curious public. It remains, nine years after its introduction, the only one of its kind sold directly to consumers. 23andMe has managed to amass a collection of DNA information about 1.2 million people, which last year began to prove its value when the company revealed it had sold access to the data to more than 13 drug companies. One, Genentech, anted up $10 million for a look at the genes of people with Parkinson’s disease.
That means 23andMe is monetizing DNA rather the way Facebook makes money from our “likes.” What’s more, it gets its customers to pay for the privilege. That idea so appeals to investors that they have valued the still-unprofitable company at over $1 billion. “Money follows data,” says Barbara Evans, a legal scholar at the University of Houston, who studies personal genetics. “It takes a lot of labor and capital to get that information in a form that is useful.”
When 23andMe made a $300 million deal with GlaxoSmithKline [GSK] in July–so the pharmaceutical giant could access a vast store of genetic data as it works on new drugs–the consumers who actually provided that data didn’t get a cut of the proceeds. A new health platform is taking a different approach: If you choose to share your own DNA data or other health records, you’ll get company shares that will later pay you dividends if that data is sold.
Before getting to the start-up that would allow you rather than a company to profit or at least somewhat monetize your DNA, I’m including a general overview of the July 2018 GSK/23andMe deal in Jamie Ducharme’s July 26, 2018 article for TIME (Note: Links have been removed),
Consumer genetic testing company 23andMe announced on Wednesday [July 25, 2018] that GlaxoSmithKline purchased a $300 million stake in the company, allowing the pharmaceutical giant to use 23andMe’s trove of genetic data to develop new drugs — and raising new privacy concerns for consumers
The “collaboration” is a way to make “novel treatments and cures a reality,” 23andMe CEO Anne Wojcicki said in a company blog post. But, though it isn’t 23andMe’s first foray into drug discovery, the deal doesn’t seem quite so simple to some medical experts — or some of the roughly 5 million 23andMe customers who have sent off tubes of their spit in exchange for ancestry and health insights
Perhaps the most obvious issue is privacy, says Peter Pitts, president of the Center for Medicine in the Public Interest, a non-partisan non-profit that aims to promote patient-centered health care.
“If people are concerned about their social security numbers being stolen, they should be concerned about their genetic information being misused,” Pitts says. “This information is never 100% safe. The risk is magnified when one organization shares it with a second organization. When information moves from one place to another, there’s always a chance for it to be intercepted by unintended third parties.
That risk is real, agrees Dr. Arthur Caplan, head of the division of medical ethics at the New York University School of Medicine. Caplan says that any genetic privacy concerns also extend to your blood relatives, who likely did not consent to having their DNA tested — echoing some of the questions that arose after law enforcement officials used a genealogy website to find and arrest the suspected Golden State Killer in April .
“A lot of people paid money to 23andMe to get their ancestry determined — fun, recreational stuff,” Caplan says. “Even though they may have signed a thing saying, ‘I’m okay if you use this information for medical research,’ I’m not sure they understood what that really meant. I’m not sure they understood that it meant, ‘Yes, we’ll go to Glaxo, and that’s where we’re really going to make a lot of money off of you.’”
A 23andMe spokesperson told TIME that data privacy is a “top priority” for the company, emphasizing that customer data isn’t used in research without consent, and that GlaxoSmithKline will only receive “summary statistics from analyses 23andMe conducts so that no single individual can be identified.”
Yes the data is supposed to be stripped of identifying information but given how many times similar claims about geolocation data have been disproved, I am skeptical. DJ Pangburn’s September 26, 2017 article (Even This Data Guru Is Creeped Out By What Anonymous Location Data Reveals About Us) for Fast Company illustrate the fragility of ‘anonymized data’,
… as a number of studies have shown, even when it’s “anonymous,” stripped of so-called personally identifiable information, geographic data can help create a detailed portrait of a person and, with enough ancillary data, identify them by name
Curious to see this kind of data mining in action, I emailed Gilad Lotan, now vice president of BuzzFeed’s data science team. He agreed to look at a month’s worth of two different users’ anonymized location data, and to come up with individual profiles that were as accurate as possible
The results, produced in just a few days’ time, range from the expected to the surprisingly revealing, and demonstrate just how “anonymous” data can identify individuals.
Last fall Lotan taught a class at New York University on surveillance that kicked off with an assignment like the one I’d given him: link anonymous location data with other data sets–from LinkedIn, Facebook, home registration and mortgage records, and other online data. “It’s not hard to figure out who this [unnamed] person is,” says Lotan. In class, students found that tracking location data around holidays proved to be the easiest way to determine who, exactly, the data belonged to. “Basically,” he says, “visits to private homes that are owned and publicly registered.”
In 2013, researchers at MIT and the Université Catholique de Louvain in Belgium published a paper reporting on 15 months of study of human mobility data for over 1.5 million individuals. What they found is that only four spatio-temporal points are required to “uniquely identify 95% of the individuals.” The researchers concluded that there was very little privacy even in raw location data. Four years later, their calls for policies rectifying concerns about location tracking have fallen largely on deaf ears.
Getting back to DNA, there was also some concern at Fox News,
Other than warnings, I haven’t seen much about any possible legislation regarding DNA and privacy in either Canada or the US.
Now, let’s get to how you can monetize your self.
Me making money off me
I’ve found two possibilities for an individual who wants to consider monetizing their own DNA.
Adele Peters’ December 13, 2018 article describes a start-up company and the model they’re proposing to allow you profit from your own DNA (Note: Links have been removed),
“You can’t say data is valuable and then take that data away from everybody,” says Dawn Barry, president and cofounder of LunaPBC, the public benefit corporation that manages the community-owned platform, called LunaDNA, which recently got SEC approval to recognize health data as currency. “What we’re finding is that [our early adopters are] very excited about the transparency of this model–that when we all come together and create value, that value flows down to the individuals who shared their data.
The platform shares some anonymized data with nonprofits, such as foundations that study rare diseases. In that case, money wouldn’t initially change hands, but “there could be intellectual property that at some point in time is monetized, and the community would share in that,” says Bob Kain, CEO and cofounder of LunaPBC. “When we have enough data in the near future, then we’ll work with pharmaceutical companies, for instance, to drive discovery for those companies. And they will pay market rates.
The company doesn’t offer DNA analysis itself, but chose to focus on data management. If you’ve sent a tube of spit to 23andMe, AncestryDNA, MyHeritage, or FamilyTree DNA, you can contribute that data to LunaDNA and get shares. (If you’d rather not let the original testing company keep your data, you can also separately take the steps to delete it.
“We looked at a number of different models to enable people to have ownership, including cryptocurrency, which is a proxy for ownership, too,” says Kain. “Cryptocurrency is hard to understand for most people, and right now, the regulatory landscape is blurry. So we thought, to move forward, we’d go with something much more traditional and easy to understand, and that is stock shares, basically.
For sharing targeted genes, you get 10 shares. For sharing your whole genome, you get 300 shares. At the moment, that’s not worth very much–the valuation takes into account the risk that the data might not be monetized, and the fact that the startup isn’t the exclusive owner of your data. The SEC filing says that the estimated fair market value of a whole genome is only $21. Some other health information is worth far less; 20 days of data from a fitness tracker garners two shares, valued at 14¢. But as more people contribute data, the research value of the whole database (and dividends) will increase. If the shareholders ever decided to sell the company itself, they would also make money that way. …
At least one effort to introduce blockchain/cryptocurrency technology to the process for monetizing your DNA garnered a lot of attention in February 2018.
A February 8, 2018 article by Eric Rosenbaum for CNBC (a US cable tv channel) explores an effort by George Church (Note: Links have been removed),
It’s probably wise to be skeptical of anyone who says they have a new idea for a blockchain-based company, or worse still, a company changing its business model to focus on the crypto world. That ice tea company that shifted its model to the blockchain, or Kodak saying its road back to riches was managing photo rights using a blockchain system. Raise eyebrow, or move directly onto outright shake of head
However, when a world renown Harvard geneticist announces he’s launching a blockchain-based start-up, it merits some attention. And it’s not the crypto-angle itself that might make you do a double-take, but the assets that will be managed, and exchanged, using digital currency: your DNA
Harvard University genetics guru George Church — one of the scientists at the forefront of the CRISPR genetic engineering revolution — announced on Wednesday a start-up, Nebula Genomics, that will use the blockchain to not only allow individuals to share their personal genome for research purposes, but retain ownership and monetize their DNA through trading of a custom digital currency.
The genomics revolution has been exponentially advanced by drastic reductions in cost. As Nebula noted in a white paper explaining its business model, the first human genome was sequenced in 2001 at a cost of $3 billion. Today, human genome sequencing costs less than $1,000, and in a few years the price will drop below $100
In fact, some big Silicon Valley start-ups, led by 23andMe, have capitalized on this rapid advance and already offer personal DNA testing kits for around $100 (sometimes with discounts even less)
Nebula took direct aim at 23andMe in its white paper, and one reason why it can offer genetic testing for less
“Today, 23andMe (23andme.com) and Ancestry (ancestry.com) are the two leading personal genomics companies. Both use DNA microarray-based genotyping for their genetic tests. It is an outdated and significantly less powerful alternative to DNA sequencing. Instead of sequencing continuous stretches of DNA, genotyping identifies single letters spaced at approximately regular intervals across the genome. …
Outdated genetic tests? Interesting, eh? Zoë Corbyn provides more information about Church’s plans in her February 18, 2018 article for the Guardian,
“Under the current system, personal genomics companies effectively own your personal genomics data, and you don’t see any benefit at all,” says Grishin [Dennis Grishin, Nebula co-founder]. “We want to eliminate the middleman.
Although the aim isn’t to provide a get-rich-quick scheme, the company believes there is potential for substantial returns. Though speculative, its modelling suggests that someone in the US could earn up to 50 times the cost of sequencing their genome – about $50,000 at current rates – taking into account both what could be made from a lifetime of renting out their genetic data, and reductions in medical bills if the results throw up a potentially preventable disease
The startup also thinks it can solve the problem of the dearth of genetic data researchers have to draw on, due to individuals – put off by cost or privacy concerns – not getting sequenced.
Payouts when you grant access to your genome would come in the form of Nebula tokens, the company’s cryptocurrency, and companies would need to buy tokens from the startup to pay people whose data they wanted to access. Though the value of a token is yet to be set and the number of tokens defined, it might, for example, take one Nebula token to get your genome sequenced. An individual new to the system could begin to earn fractions of a token by taking part in surveys about their heath posted by prospective data buyers. When someone had earned enough, they could get sequenced and begin renting out their data and amassing tokens. Alternatively, if an individual wasn’t yet sequenced they may find data buyers willing to pay for or subsidise their genome sequencing in exchange for access to it. “Potentially you wouldn’t have to pay out of pocket for the sequencing of your genome,” says Grishin.
In all cases, stress Grishin and Obbad [Kamal Obbad, Nebula co-founder], the sequence would belong to the individual, so they could rent it out over and over, including to multiple companies simultaneously. And the data buyer would never take ownership or possession of it – rather, it would be stored by the individual (for example in their computer or on their Dropbox account) with Nebula then providing a secure computation platform on which the data buyer could compute on the data. “You stay in control of your data and you can share it securely with who you want to,” explains Obbad. Nebula makes money not by taking any transaction fee but by being a participant providing computing and storage services. The cryptocurrency would be able to be cashed out for real money via existing cryptocurrency exchanges.
Hopefully, Luna and Nebula, as well as, any competitors in this race to allow individuals to monetize their own DNA will have excellent security.
For the curious, you can find Luna here and Nebula here.Note: I am not endorsing either company or any others mentioned here. This posting is strictly informational.
Libraries, archives, records management, oral history, etc. there are many institutions and names for how we manage collective and personal memory. You might call it a peculiarly human obsession stretching back into antiquity. For example, there’s the Library of Alexandria (Wikipedia entry) founded in the third, or possibly 2nd, century BCE (before the common era) and reputed to store all the knowledge in the world. It was destroyed although accounts differ as to when and how but its loss remains a potent reminder of memory’s fragility.
These days, the technology community is terribly concerned with storing ever more bits of data on materials that are reaching their limits for storage.I have news of a possible solution, an interview of sorts with the researchers working on this new technology, and some very recent research into policies for cryptocurrency mining and development. That bit about cryptocurrency makes more sense when you read what the response to one of the interview questions.
It seems University of Alberta researchers may have found a way to increase memory exponentially, from a July 23, 2018 news item on ScienceDaily,
The most dense solid-state memory ever created could soon exceed the capabilities of current computer storage devices by 1,000 times, thanks to a new technique scientists at the University of Alberta have perfected.
“Essentially, you can take all 45 million songs on iTunes and store them on the surface of one quarter,” said Roshan Achal, PhD student in Department of Physics and lead author on the new research. “Five years ago, this wasn’t even something we thought possible.”
Previous discoveries were stable only at cryogenic conditions, meaning this new finding puts society light years closer to meeting the need for more storage for the current and continued deluge of data. One of the most exciting features of this memory is that it’s road-ready for real-world temperatures, as it can withstand normal use and transportation beyond the lab.
“What is often overlooked in the nanofabrication business is actual transportation to an end user, that simply was not possible until now given temperature restrictions,” continued Achal. “Our memory is stable well above room temperature and precise down to the atom.”
Achal explained that immediate applications will be data archival. Next steps will be increasing readout and writing speeds, meaning even more flexible applications.
“With this last piece of the puzzle now in-hand, atom-scale fabrication will become a commercial reality in the very near future,” said Wolkow. Wolkow’s Spin-off [sic] company, Quantum Silicon Inc., is hard at work on commercializing atom-scale fabrication for use in all areas of the technology sector.
To demonstrate the new discovery, Achal, Wolkow, and their fellow scientists not only fabricated the world’s smallest maple leaf, they also encoded the entire alphabet at a density of 138 terabytes, roughly equivalent to writing 350,000 letters across a grain of rice. For a playful twist, Achal also encoded music as an atom-sized song, the first 24 notes of which will make any video-game player of the 80s and 90s nostalgic for yesteryear but excited for the future of technology and society.
As noted in the news release, there is an atom-sized song, which is available in this video,
For interested parties, you can find Quantum Silicon (QSI) here. My Edmonton geography is all but nonexistent, still, it seems to me the company address on Saskatchewan Drive is a University of Alberta address. It’s also the address for the National Research Council of Canada. Perhaps this is a university/government spin-off company?
I sent some questions to the researchers at the University of Alberta who very kindly provided me with the following answers. Roshan Achal passed on one of the questions to his colleague Taleana Huff for her response. Both Achal and Huff are associated with QSI.
Unfortunately I could not find any pictures of all three researchers (Achal, Huff, and Wolkow) together.
Roshan Achal (left) used nanotechnology perfected by his PhD supervisor, Robert Wolkow (right) to create atomic-scale computer memory that could exceed the capacity of today’s solid-state storage drives by 1,000 times. (Photo: Faculty of Science)
(1) SHRINKING THE MANUFACTURING PROCESS TO THE ATOMIC SCALE HAS
ATTRACTED A LOT OF ATTENTION OVER THE YEARS STARTING WITH SCIENCE
FICTION OR RICHARD FEYNMAN OR K. ERIC DREXLER, ETC. IN ANY EVENT, THE
ORIGINS ARE CONTESTED SO I WON’T PUT YOU ON THE SPOT BY ASKING WHO
STARTED IT ALL INSTEAD ASKING HOW DID YOU GET STARTED?
I got started in this field about 6 years ago, when I undertook a MSc
with Dr. Wolkow here at the University of Alberta. Before that point, I
had only ever heard of a scanning tunneling microscope from what was
taught in my classes. I was aware of the famous IBM logo made up from
just a handful of atoms using this machine, but I didn’t know what
else could be done. Here, Dr. Wolkow introduced me to his line of
research, and I saw the immense potential for growth in this area and
decided to pursue it further. I had the chance to interact with and
learn from nanofabrication experts and gain the skills necessary to
begin playing around with my own techniques and ideas during my PhD.
(2) AS I UNDERSTAND IT, THESE ARE THE PIECES YOU’VE BEEN
WORKING ON: (1) THE TUNGSTEN MICROSCOPE TIP, WHICH MAKE[s] (2) THE SMALLEST
QUANTUM DOTS (SINGLE ATOMS OF SILICON), (3) THE AUTOMATION OF THE
QUANTUM DOT PRODUCTION PROCESS, AND (4) THE “MOST DENSE SOLID-STATE
MEMORY EVER CREATED.” WHAT’S MISSING FROM THE LIST AND IS THAT WHAT
YOU’RE WORKING ON NOW?
One of the things missing from the list, that we are currently working
on, is the ability to easily communicate (electrically) from the
macroscale (our world) to the nanoscale, without the use of a scanning
tunneling microscope. With this, we would be able to then construct
devices using the other pieces we’ve developed up to this point, and
then integrate them with more conventional electronics. This would bring
us yet another step closer to the realization of atomic-scale
(3) PERHAPS YOU COULD CLARIFY SOMETHING FOR ME. USUALLY WHEN SOLID STATE
MEMORY IS MENTIONED, THERE’S GREAT CONCERN ABOUT MOORE’S LAW. IS
THIS WORK GOING TO CREATE A NEW LAW? AND, WHAT IF ANYTHING DOES
;YOUR MEMORY DEVICE HAVE TO DO WITH QUANTUM COMPUTING?
That is an interesting question. With the density we’ve achieved,
there are not too many surfaces where atomic sites are more closely
spaced to allow for another factor of two improvement. In that sense, it
would be difficult to improve memory densities further using these
techniques alone. In order to continue Moore’s law, new techniques, or
storage methods would have to be developed to move beyond atomic-scale
The memory design itself does not have anything to do with quantum
computing, however, the lithographic techniques developed through our
work, may enable the development of certain quantum-dot-based quantum
(4) THIS MAY BE A LITTLE OUT OF LEFT FIELD (OR FURTHER OUT THAN THE
OTHERS), COULD;YOUR MEMORY DEVICE HAVE AN IMPACT ON THE
DEVELOPMENT OF CRYPTOCURRENCY AND BLOCKCHAIN? IF SO, WHAT MIGHT THAT
I am not very familiar with these topics, however, co-author Taleana
Huff has provided some thoughts:
Taleana Huff (downloaded from https://ca.linkedin.com/in/taleana-huff]
“The memory, as we’ve designed it, might not have too much of an
impact in and of itself. Cryptocurrencies fall into two categories.
Proof of Work and Proof of Stake. Proof of Work relies on raw
computational power to solve a difficult math problem. If you solve it,
you get rewarded with a small amount of that coin. The problem is that
it can take a lot of power and energy for your computer to crunch
through that problem. Faster access to memory alone could perhaps
streamline small parts of this slightly, but it would be very slight.
Proof of Stake is already quite power efficient and wouldn’t really
have a drastic advantage from better faster computers.
Now, atomic-scale circuitry built using these new lithographic
techniques that we’ve developed, which could perform computations at
significantly lower energy costs, would be huge for Proof of Work coins.
One of the things holding bitcoin back, for example, is that mining it
is now consuming power on the order of the annual energy consumption
required by small countries. A more efficient way to mine while still
taking the same amount of time to solve the problem would make bitcoin
much more attractive as a currency.”
Thank you to Roshan Achal and Taleana Huff for helping me to further explore the implications of their work with Dr. Wolkow.
As usual, after receiving the replies I have more questions but these people have other things to do so I’ll content myself with noting that there is something extraordinary in the fact that we can imagine a near future where atomic scale manufacturing is possible and where as Achal says, ” … storage methods would have to be developed to move beyond atomic-scale [emphasis mine] storage”. In decades past it was the stuff of science fiction or of theorists who didn’t have the tools to turn the idea into a reality. With Wolkow’s, Achal’s, Hauff’s, and their colleagues’ work, atomic scale manufacturing is attainable in the foreseeable future.
Hopefully we’ll be wiser than we have been in the past in how we deploy these new manufacturing techniques. Of course, before we need the wisdom, scientists, as Achal notes, need to find a new way to communicate between the macroscale and the nanoscale.
A study [behind a paywall] published in Energy Research & Social Science warns that failure to lower the energy use by Bitcoin and similar Blockchain designs may prevent nations from reaching their climate change mitigation obligations under the Paris Agreement.
The study, authored by Jon Truby, PhD, Assistant Professor, Director of the Centre for Law & Development, College of Law, Qatar University, Doha, Qatar, evaluates the financial and legal options available to lawmakers to moderate blockchain-related energy consumption and foster a sustainable and innovative technology sector. Based on this rigorous review and analysis of the technologies, ownership models, and jurisdictional case law and practices, the article recommends an approach that imposes new taxes, charges, or restrictions to reduce demand by users, miners, and miner manufacturers who employ polluting technologies, and offers incentives that encourage developers to create less energy-intensive/carbon-neutral Blockchain.
“Digital currency mining is the first major industry developed from Blockchain, because its transactions alone consume more electricity than entire nations,” said Dr. Truby. “It needs to be directed towards sustainability if it is to realize its potential advantages.
“Many developers have taken no account of the environmental impact of their designs, so we must encourage them to adopt consensus protocols that do not result in high emissions. Taking no action means we are subsidizing high energy-consuming technology and causing future Blockchain developers to follow the same harmful path. We need to de-socialize the environmental costs involved while continuing to encourage progress of this important technology to unlock its potential economic, environmental, and social benefits,” explained Dr. Truby.
As a digital ledger that is accessible to, and trusted by all participants, Blockchain technology decentralizes and transforms the exchange of assets through peer-to-peer verification and payments. Blockchain technology has been advocated as being capable of delivering environmental and social benefits under the UN’s Sustainable Development Goals. However, Bitcoin’s system has been built in a way that is reminiscent of physical mining of natural resources – costs and efforts rise as the system reaches the ultimate resource limit and the mining of new resources requires increasing hardware resources, which consume huge amounts of electricity.
Putting this into perspective, Dr. Truby said, “the processes involved in a single Bitcoin transaction could provide electricity to a British home for a month – with the environmental costs socialized for private benefit.
“Bitcoin is here to stay, and so, future models must be designed without reliance on energy consumption so disproportionate on their economic or social benefits.”
The study evaluates various Blockchain technologies by their carbon footprints and recommends how to tax or restrict Blockchain types at different phases of production and use to discourage polluting versions and encourage cleaner alternatives. It also analyzes the legal measures that can be introduced to encourage technology innovators to develop low-emissions Blockchain designs. The specific recommendations include imposing levies to prevent path-dependent inertia from constraining innovation:
Registration fees collected by brokers from digital coin buyers.
“Bitcoin Sin Tax” surcharge on digital currency ownership.
Green taxes and restrictions on machinery purchases/imports (e.g. Bitcoin mining machines).
Smart contract transaction charges.
According to Dr. Truby, these findings may lead to new taxes, charges or restrictions, but could also lead to financial rewards for innovators developing carbon-neutral Blockchain.
The press release doesn’t fully reflect Dr. Truby’s thoughtfulness or the incentives he has suggested. it’s not all surcharges, taxes, and fees constitute encouragement. Here’s a sample from the conclusion,
The possibilities of Blockchain are endless and incentivisation can help solve various climate change issues, such as through the development of digital currencies to fund climate finance programmes. This type of public-private finance initiative is envisioned in the Paris Agreement, and fiscal tools can incentivize innovators to design financially rewarding Blockchain technology that also achieves environmental goals. Bitcoin, for example, has various utilitarian intentions in its White Paper, which may or may not turn out to be as envisioned, but it would not have been such a success without investors seeking remarkable returns. Embracing such technology, and promoting a shift in behaviour with such fiscal tools, can turn the industry itself towards achieving innovative solutions for environmental goals.
I realize Wolkow, et. al, are not focused on cryptocurrency and blockchain technology per se but as Huff notes in her reply, “… new lithographic techniques that we’ve developed, which could perform computations at significantly lower energy costs, would be huge for Proof of Work coins.”
Whether or not there are implications for cryptocurrencies, energy needs, climate change, etc., it’s the kind of innovative work being done by scientists at the University of Alberta which may have implications in fields far beyond the researchers’ original intentions such as more efficient computation and data storage.
ETA Aug. 6, 2018: Dexter Johnson weighed in with an August 3, 2018 posting on his Nanoclast blog (on the IEEE [Institute of Electrical and Electronics Engineers] website),
Researchers at the University of Alberta in Canada have developed a new approach to rewritable data storage technology by using a scanning tunneling microscope (STM) to remove and replace hydrogen atoms from the surface of a silicon wafer. If this approach realizes its potential, it could lead to a data storage technology capable of storing 1,000 times more data than today’s hard drives, up to 138 terabytes per square inch.
As a bit of background, Gerd Binnig and Heinrich Rohrer developed the first STM in 1986 for which they later received the Nobel Prize in physics. In the over 30 years since an STM first imaged an atom by exploiting a phenomenon known as tunneling—which causes electrons to jump from the surface atoms of a material to the tip of an ultrasharp electrode suspended a few angstroms above—the technology has become the backbone of so-called nanotechnology.
In addition to imaging the world on the atomic scale for the last thirty years, STMs have been experimented with as a potential data storage device. Last year, we reported on how IBM (where Binnig and Rohrer first developed the STM) used an STM in combination with an iron atom to serve as an electron-spin resonance sensor to read the magnetic pole of holmium atoms. The north and south poles of the holmium atoms served as the 0 and 1 of digital logic.
The Canadian researchers have taken a somewhat different approach to making an STM into a data storage device by automating a known technique that uses the ultrasharp tip of the STM to apply a voltage pulse above an atom to remove individual hydrogen atoms from the surface of a silicon wafer. Once the atom has been removed, there is a vacancy on the surface. These vacancies can be patterned on the surface to create devices and memories.
If you have the time, I recommend reading Dexter’s posting as he provides clear explanations, additional insight into the work, and more historical detail.
