Let’s talk about internet connected gadgets. Not just your phone or PC—and not even a microwave oven or light bulb. Instead, think of everyday objects that are much smaller and much less expensive. Think of things that seemingly have no need to talk with you.

Now think of applications in which these tiny things need to communicate with each other and not just with you. Think of the cost of this “thing” compared to the added cost of continuous communications. Do so many things really need to talk in the first place?

First, there were Trackers…

Have you tried one of those tracking devices that help you find a lost bicycle or wallet? Tile is the most visible brand. They offer trackers shaped like dog tag, a fat button or a credit card. They recently began offering users the ability to replace the battery. In the past, you had to buy new trackers every year.

Trackers are useful, but connectivity is either…

• Very expensive: Each devices requires a mobile phone data plan
  —or—
• Intermittent and short range: Tile uses Bluetooth and relies on a community of owners to “pick up” on your lost or stolen object. This only occurs if another user stumbles into close range range and with their Tile app active on a mobile phone.

Tile was cool in its heyday, but that day is passing as we transition into the Internet of Things (IOT). It took me a few years to fully embrace the need for an internet of “things” or how it differs from the internet that we use every day. In an effort to more quickly bring about your own Ahahh! moment, consider just one example.

The Chandelier (an example with apologies to Sia)

Consider a huge chandelier across the domed ceiling of a grand opera house. It has 85,000 tiny LEDs that can throb and pulse during animated light shows. Each individual light is replaceable—only 10¢. But getting a scaffold and a maintenance crew to the 50 foot dome takes 6 hours and costs almost $500.

Every month, one or two of the tiny lights go dark (or get stuck on the wrong color). Fortunately, expensive maintenance can be delayed. A few bad LEDs cannot be seen from the auditorium below. They are only a problem when many lights go dark:

a) More than 2% of bulbs —OR—
b) More than 8 bulbs in any cubic region of 250 LEDs —OR—
c) More than 3 bulbs positioned at a critical juncture of special-effect animation
d) Any LED programmed to be green for more than 250 mS during the Disney Little-Mermaid animation

These minimum operating conditions may sound complex, but they were determined at the time of installation by a meticulous trial with a focus group and survey forms. Dozens of volunteers looked up at the chandelier and watched several programmed light shows.

Trying to count faulty lights and measure them against these criteria before each performance is nearly impossible. Should we chuck these standards and just leave the maintenance decision in the hands of whomever is managing the facility each night?

No. Standards are good. There is a better way.

Imagine if all the little LEDs could communicate with each other and generate a weighted vote as to whether maintenance is required. Now, imagine that the added circuitry to communicate between LEDs—and even to managers and maintenance staff—cost no more than the LED itself. Just pennies for the circuit. No communications infrastructure or subscription is needed at all.

This example may seem a bit extreme, but it is taken from real life, and a perfect example of the Internet of Things. This is just the beginning. As IOT takes off, a connected society will venture far beyond Bluetooth trackers into applications that we cannot yet imagine.

But how will the internet things be connected—especially if so many devices are tiny, inexpensive and portable? We cannot expect every dog collar and portable asset to have a mobile subscription plan and an IMEI/MEID.

And short range tracking (like the Bluetooth Tile) is not too helpful for keeping tabs on your dog when he gets off leash. Or perhaps you want to track an asset that is less precious—for example, a soccer ball. You don’t just want to find it, you want to study game dynamics as it is kicked across a field. What about your favorite earrings? They belonged to your great grandmother. Imagine that they could never be misplaced. With IOT, everything possible. Apps and benefits are heading toward us like a freight train.

IOT doesn’t require 5G speed, but to be truly transformative, it requires ubiquitous, low-power and free connectivity. Coverage must be thorough, at least at a community level.

Do We Really Need IOT?

You bet we do! Just envision possibilities.

With miniaturization and the rapidly dropping cost of electronics, there are some tiny or inexpensive things could benefit greatly by constant connectivity. Today, my washing machine and air conditioner are WiFi enabled. Connectivity is even built into light bulbs.

But early connected smart home gadgets are designed primarily to talk within a home. When traveling, you might want an alert if water is leaking into the cellar. But let’s face it: When at the office or on vacation, most people don’t care to dim the kitchen lights or know when a load of laundry is ready for transfer to the dryer.

This is starting to change. Gadget makers all over the world are preparing for an era of remarkable information and utility that will emerge when devices communicate not just with their owners, but with each other. When tiny things can talk, a world with free, ubiquitous and redundant connectivity, will bring unexpected and remarkable benefits.

How to Get from Here to There?

All this requires simple, free and ubiquitous wide area networking. Most analysts expect that the brave new world will take wings until a popular, widely deployed internet access method emerges—one that does not require a service provider.

Does free internet access, with community wide coverage and a sustainable business model exist?

Enter the people’s network: The Helium hotspot. With a splashy adoption campaign, it is positioned to be the first successful mass-deployment of a very long range, low power signalling standard. If successful, Helium could jump start a category of access and coverage that is just what is needed for the next big thing.

The Helium hotspot, is a crossover between a residential router, and community internet access. Most importantly, it disintermediates the process. No ISP? Don’t worry! It is not required to get into the game and to enjoy significant benefits.

I think of Helium as Rooftop Communications on steroids (an early community mesh network that was way ahead its time). If 5 or more individuals in a typical city set up their own hotspot, every user enjoys shared community access to the Internet—even if only one of participant has internet service. In fact, a bridge to the legacy internet is not even an issue to access resources and data within the community. Every town service, store, event, school and library is online without anyone having a paid subscription to any service provider.

Helium is just beginning to roll out across the world. Early adopters acquire a Helium hotspot and they effectively “own” their city. At first, it works at moderately low speeds and over very long distances. Only a few are needed to kick start a city. When 20 or 30 residents join the party, network speed, coverage, consistency and overall utility become compelling. Not 5G or 4G—but capable of servicing critical needs on the go or as a back up method of Internet access. When this clever IOT network gets traction, it will eventually service most internet needs other than video.

Helium is the first Consumer product to use the low-power LoRa radio standard (Helium calls it “LongFi”). User owned Hotspots form a super mesh-network that the company hopes will cover entire continents. Unlike your router or smartphone hotspot, with Helium, there is no ISP or cell tower. Your neighbors are your peers and your entry ramp to the internet for services that are still on a legacy, subscriber network.

Enter The Blockchain: Seriously—Adoption It is token powered!

As if this weren’t exciting enough, Helium adoption is powered by a blockchain—like Bitcoin. No kidding!

Don’t let this deter you from testing Helium and taking control of your own city. Regardless of your opinion on Bitcoin and crypto, the blockchain is a clever lever to incentivize and reward adoption.

Helium hotspot ads are everywhere, but the first LongFi router is not cheap. Buyers are investing in the long game. Early adopters won’t find immediate value in hosting other users, but you will be amply rewarded as the technology is adopted. Hence, a blockchain token reward mechanism. The Helium reward token a functional cryptocurrency token. Some call it an Independent Coin Offering (ICO). Whaaat?! Hold on! Aren’t ICOs rip-offs?…

I have broad contempt for ICOs (they are all scams!). This fervent opinion forced me to carefully evaluate my enthusiasm for Helium. It almost led me to abandon research and look for an alternate long-range, decentralized communications ecosystem.

But the blockchain does not necessarily make for a bad actor. A functional token with no underlying pyramid scheme is not an ICO. It is a clever mechanism to encourage viral adoption of a chicken-and-egg technology; one that offers enormous public benefit.

Technology Application & Business Model

LoRa can achieve competitive web access speeds at 1~3 Km. Helium hotspots will more likely have mesh-hand-off spacing of 15~20 Km at first. This results in a signal of 5 kbps or less. Depending on how effective are the hotspot and hand-off incentives, Helium may ultimately compete with sky-based WiFi, satellite schemes or community WiFi as a free moderate-speed, internet service.Helium is intended for IOT devices, but can also be used as a last mile layer for user Internet access. During the early build out of infrastructure in any region, it is clearly optimized for low speed IOT communications.

Conclusion:

Helium doesn’t completely satisfy requirements that we set forth in the very first paragraph above. I assume that it uses a proprietary standard to poll and packetize data. (I am not sure of this. Perhaps someone working with the project reach out with a clarification). And at $495 for a long range, low power Helium hotspot/router, it may be a bit early for all but the most bold entrepreneur to experiment with Helium. If you don’t live in a large and densely populated urban area, you are unlikely to find many peers with whom to share spectrum, data and gateways.

But if you open your mind to the possibilities: tools, gadgets and services that can benefit from private networks or municipal infrastructure that was previously the exclusive domain of town governments, railroads and first responders… If you can imagine these things—or a profitable role in accommodating these things—then a personal Helium Hotspot may be in your future.

I plan to jump in with both feet. I will be shaping my career around Helium. It’s a bit early, but that’s the whole point. For me, it is a gamble worth taking.

If the subject is important to me—or if there is any chance that it might influence my view of the world, I check it at Snopes. The reputable web site confirms or debunks many urban legends and all sorts of viral web hype.

You never know what you might learn at Snopes. You can easily be lured into a rabbit hole, digging into the site beyond whatever prompted your visit in the first place.

Fact-checking can be fun! For example:

• Debunked: There are no alligators living in New York sewers. If a resident flushes a baby alligator in a toilet, it cannot survive the temperature or the toxic soup that flows through the sewers of a big city. Florida: perhaps; New York: impossible!
  
• Debunked: Ronald Reagan did not write a diary entry in which he describes his vice president’s son (the future president George W. Bush) as a shiftless ne’er-do-well, roaming about the White House.*
  
• Confirmed: This one is true! In 1976, during the filming of TV series, Six Million Dollar Man in Long Beach California, an arm fell off a scary, fun-house prop. A film crew found that it was the cadaver of outlaw Elmer McCurdy, who died in 1911.

I’m still occasionally guilty of passing along a story I long believed was gospel. In a few cases, it didn’t occur to me that something accepted as fact might be an urban legend—or that my acceptance of a tall tale is colored by my opinions about economics, society and business. Hopefully, this is a rare and diminishing lapse. I have learned to fact check narratives—especially if I feel compelled to pass one along.

Conspiracies Theories: Often false!

In general, I am unlikely to suspect a conspiracy behind events of the day—with the exception of national politics, where conspiracy is a natural and pervasive tactic. The problem is my optimistic view of human nature. While businesses have a profit motive and a responsibility to stakeholders, I feel that most are driven by ethics and that executing a plan within the bounds of ethics is simply good for business.

Let me tell you about one viral, big-business story that I had believed for decades and another that I did not believe until I was presented with too many facts to refute.

1. No Conspiracy Here

There was no secret meeting or conspiracy by titans of the car, rubber, oil or steel industries to kill off public transportation and alter city layouts to drive auto sales. Streetcars were already mired in politics and graft; family, income was increasing, and the car was already becoming popular.

That tall tale says that Harvey Firestone, Henry Ford and John D. Rockefeller conspired to eliminate street cars and redesign the urban landscape, so that Americans would need individual family cars, rather than use public transportation—Or that this is the reason that we must drive to a big mall today rather than live in towns centered around a community center, church, city hall and general store.

The theory claims that the three automobile bosses had a secret meeting in San Francisco with a goal of increasing sales of cars, rubber, steel and oil. (In some versions of the story, Rockefeller (oil) is replaced Andrew Carnegie (steel). Ironically, I only learned that the entire story was an urban legend as I started to write this introduction to the true story below.

2. Shocking Conspiracy — This one is true

More than any other lie, here is a food industry conspiracy crafted and delivered by big business. It manipulated one of our most trusted universities, a major medical journal and the public psyche. The result: Thousands of Americans died and millions were misled into obesity and heart disease. More than any other fiendish plot, this one event has killed people and damaged human health more than any other conspiracy in modern history.

In 1967, the sugar industry shaped 50 years of research into the role of nutrition and heart disease, including many of today’s dietary recommendations, by paying Harvard researches to lie about the role of food in obesity and heart disease. They schemed and succeeded at shifting blame from sugar to fats.

Believing lies: I grew up becoming fully indoctrinated!…

For much of the next five decades, the wheat and grain industry promulgated the lie to enormous advantage. I grew up thinking that bread, pasta, rice and potato are terrific sources of healthy fiber and minerals (much like vegetables)—and that they ensure clean pipes. I thought that oil and fats are bad, because they deposit plaque in arteries. It never occurred to me that oils can maintain healthy weight, that your brain needs fat, that carbs lead a body to manufacture the fat that causes cardiovascular disease.

I believed that skim milk is less fattening than whole milk and that margarine is healthier than butter (dairy), tallow (beef fat) or lard (pig fat). Perhaps most damning: I believed that Canola oil (synthetically extracted from rape seed) was a healthy oil, because it is unsaturated. Today, I have learned it is toxic.

How does a 20th century academic
with advanced degrees get so misled?

Answer: I succumbed to a startlingly successful conspiracy; a long game in which it is now difficult to punish sugar industry perpetrators. Ultimately, they will be held to account by journalists, and a new generation of doctors, researchers and academics.

The New York Times article linked below appeared in 2016. More recently, the story is finally going viral. Citation by other reputable outlets is growing quickly.

Some conspiracy theories are true. Instead of passing along an urban legend, forward the shocking truth about sugar and carbs to a friend or colleague. Share this Lifeboat article. Think of the good achieved if you turn around the diet of just one acquaintance.

* Fiction: Ronald Reagan did not write this; (I believed it for 30 years):

“A moment I’ve been dreading. George brought his ne’re-do-well son around this morning and asked me to find the kid a job. Not the political one who lives in Florida. The one who hangs around here all the time looking shiftless. This so-called kid is already almost 40 and has never had a real job. Maybe I’ll call Kinsley over at The New Republic and see if they’ll hire him as a contributing editor or something. That looks like easy work.”

Earlier today, Genevieve O’Hagan updated Lifeboat readers on this week’s momentous event in Astronomy. At least, I find it fascinating—and so, I wish to add perspective…

30 years ago, astronomer Jack Hills demonstrated the math behind what has become known as the “Hills Mechanism”. Until this week, the event that he described had never been observed.* But his peer astronomers agreed that the physics and math should make it possible…

Hills explained that under these conditions, a star might be accelerated to incredible speeds — and might be even flung out of its galaxy:

• Suppose that a binary star passes close to a black hole, like the one at the center of our galaxy
• The pair of self-orbiting stars is caught up in the gravity well of a black hole, but not sucked in

If conditions are right, one star ends up orbiting the back hole while the other is jettisoned at incredible speed, yet holding onto its mass and shape. All that energy comes from the gravity of the black hole and the former momentum of the captured star. [20 sec animation] [continue below]

This week, astronomers found clear evidence of this amazing event and traced it back to our galactic center: Five million years ago — as our ancestors learned to walk upright — a star that passed close to the massive black hole at The Milky Way center was flung away at a staggering 6 million Kmh. It is traveling so fast, that it is no longer bound to our galaxy or galactic cluster. It is headed out of the galaxy.

• Rifle Bullet: Can exceed Mach 3 (2,300 mph)
• Apollo Rocket: Reached 25,000 mph; Earth escape velocity.
• Juno Probe: 165,000 mph, a record prior to 2019. (It used Jupiter’s gravity to accelerate)
• Parker Probe: 213,000 mph (Nov 2019), but will soon reach 430,000 in a tight arc around the Sun

* Prior to this week, astronomers have observed a few stars traveling inexplicably at incredible speeds. But this is the first time, that they have traced the trajectory back to a black hole and the conditions described by Jack Hills.

Reader, Tamia Boyden asks this question:

In the 90s, how could we access the internet without WiFi?

This post began as an answer to that question at Quora. In the process of answering, I compiled this history of public, residential Internet access. Whether you lived through this fascinating social and technical upheaval or simply want to explore the roots of a booming social phenomenon, I hope you will find the timeline and evolution as interesting as I do.

I have included my answer to Tamia’s question, below. But first, let’s get a quick snapshot of the highlights. This short bullet-list focuses on technical milestones, but the history below, explains the context, social phenomenon and implications.

Short Version:

1965 Hypertext link defined
1970s TCP/IP packet protocol
1983 TCP adopted by Arpanet
1989~91 Http protocol
1991 Public access begins
1995 Netscape Mozilla (1st browser)

— Scroll below Q&A for context and commentary* —

Question: In the 90s, how could we access the internet without WiFi?

Answer: We didn’t need WiFI in the 1990s and we don’t need it now. In both era’s, you can simply attach your PC to the internet with a network cable. If your PC does not have an Ethernet port, you can add a miniature USB-Ethernet adapter. They are inexpensive.

Likewise, before internet service was available to almost every home and business, you could access the internet via telephone modem, or by visiting a library, internet cafe or office that had a leased line for fast access.*

In each case, adoption goes hand in hand with infrastructure build-out, cost reduction and (in the case of WiFi), the desire to move about the home or community more freely.

*A brief history of Public Internet Access

1965: The concept of “hypertext” and clickable “links”. But demonstrations were limited to a single computer or a local network. The first mouse was patented in 1967. But for the next 15 years, few people used a mouse or pointing device.

1970s: The Internet and its predecessor, the Arpanet, was a constellation of networked terminal access tools that connected universities and research labs. Finding material and accessing it required command line jargon that limited its use. You could access the web and most standards were in place—but there was no universal browser that incorporated hypertext links.

1983: Apple introduces the Lisa (predecessor to the Macintosh). It included a mouse, which most people had never used before. Not to be outdone, Microsoft offered an aftermarket Mouse for $195 which came bundled with Word and Notepad.

1991: The public gained access in 1991 after Tim Berners-Lee, posted a summary of the project and the http standard that he pioneered.

1995: Netscape introduces Mozilla (later renamed Netscape browser). It kicked off a gradual migration of data from FTP and Usenet servers to web pages (http protocol) and an explosion in services and subscribers.

Final Impediments to Adoption: Complexity & Connection infrastructure

In-home use still required special equipment (a telephone modem) and applications had to be installed from a CD or multiple floppy discs. These apps modified the operating system by adding a TCP stack and a Windows Socket API. Prior to these things being bundled into new PCs, the process was a daunting. And so, for the next 10 years, many people accessed the internet from Internet cafes, schools or libraries.

1999: The WiFi standard was introduced in 1997. But it had technical limitations that limited its appeal. In 1997, 802.11b, the first widely used and supported WiFi standard, brought the freedom of movement into homes. This occurred at around the same time that many people were moving from a desktop or tower computer to a laptop.

WiFi-b and later g and n helped to propel convenient Internet access from anywhere within a home. Over the next decade, consumers came to expect an available WiFi signal in offices, schools, restaurants, hotels and airports.

2003: Rise of Social Media

Myspace wasn’t the first social media platform. Friendster beat it out by almost a year. But Myspace was the first to go viral and nationwide among many demographics. Along with Facebook—which eclipsed Myspace in subscriber growth—social media platforms turned many infrequent users into constantly-connected consumers.

• Friendster March 2002
• MySpace August 2003
• Facebook February 2004
• Twitter March 2006

2007: Apple and AT&T introduced the iPhone in the summer. Prior to 2007, flip phones offered web access via a crude browser built into Palm or Symbion, the OS used by Palm Pilot, Nokia, Motorola and others. But the iPhone kicked off the Smart Phone, a new category of must-have consumer gadgets, which lead to ubiquitous, mobile internet access.

1995 ~ 2020

Gradually, the Internet become a mass market phenomenon. But slow connection speeds and the need to suspend telephone calls limited its use. Between 1978 and 1996, telephone modems gradually improved technology from 300 bps to 56,000 Baud (access at ~25 kbps).

After 1996, consumers gradually switched away from using their telephone lines to a dedicated internet service. Homes connect to an ISP (Internet Service Provider) via either existing phone wire (ISDN), TV cables, Fiberoptic or Wireless-to-home.

Today (2019), it is not uncommon to have residential internet access via a Gigabit fiberoptic connection.

Scientists believe they may have caught a glimpse of a parallel universe bumping up against ours.

They’ve seen hints in signals from the most distant points of the universe that suggest the fabric of our universe has been disrupted by another incredibly different universe. Their analysis may be the proof for the multiverse theory.

According to researchers: “Dr Ranga-Ram Chary examined the noise and residual signals in the cosmic microwave background left over from the Big Bang (pictured) and found a number of scattered bright spots which he believes may be signals of another universe bumping into our own billions of years ago.”

At least that’s the tentative conclusion researchers have come to. According to some cosmological theories, collisions of alternative universes should be possible. Theories conclude that our universe is like a bubble among many.

Once a universe begins in a big bang type setting, it never stops expanding. That goes for all the universes. So it makes sense they’d periodically bump into one another.

They’re all likely in a row, say researchers, vibrating, bouncing around, and rubbing up on each other.

Dr. Chary believes that the signal he’s received indicate that this other universe is extremely different from our own. He says it could have a ratio of subatomic particles called photos and baryons that are about 10 fold greater than in our universe.

Dr. Chary explains, “The fine tuning of parameters in the early universe required to reproduce our present day universe suggests that our universe may simply be a region within an eternally inflating super-region. Many other regions beyond our observable universe would exist with each such region governed by a different set of physical parameters than the ones we have measured for our universe.” More research will need to be done, but this could be the beginning of some very interesting discoveries.

But most of us never believed that we would face an existential crisis, except perhaps a potential for a 3rd World War. Yet, here we are: Burning the forests, killing off unspeakable numbers of species (200 each day), cooking the planet, melting the ice caps, shooting a hole in the ozone, and losing more land to the sea each year.

Regading the urgent message of Greta Thunberg, below, I am at a loss for words. Seriously, there is not much I can add to the 1st video below.

Information about climate change is all around us. Everyone knows about it; Most people understand that it is real and it that poses an existential threat, quite possibly in our lifetimes. In our children’s lives, it will certainly lead to war, famine, cancer, and massive loss of land, structures and money. It is already raising sea level and killing off entire species at thousands of times the natural rate.

Yet, few people, organizations or governments treat the issue with the urgency of an existential crisis. Sure! A treaty was signed and this week, Jeff Bezos committed to reducing the carbon footprint of the world’s biggest retailer. But have we moved in the right direction since the Paris Accords were signed 4 years ago? On the contrary, we have accelerated the pace of self-destruction.

I want speak out—and, of course, this Blog post is my way of doing it. But I am at a loss for words, because everything I want to say is so deftly articulated by 15 year old Greta Thunberg. I cannot possibly add to or improve upon her message.

Greta is not your typical hero. She is a child, has Asperger’s, and is a high school Sophomore, yet she is a truant. She regularly skips class, because she feels that doing her own thing is more important than education. She is absolutely right…

This week Greta educated the UN, US Congress and former President Obama (because the current president cannot grasp her message). She also led a protest campaign that attracted millions of Millennials in more than 100 cities across Asia, Europe, Australia, and the Americas.

Greta Thunberg is racing to save the world—and all of humanity while she is at it.

Rather than link to her talk before Congress or the UN, or this overly-slick PSA, I choose three videos. The last one is only 49 seconds). Don’t have the time to pause for a video?—not even at bed time? Please reconsider. This one is really, really important. Even more important than not texting and driving. If ever you felt that there was something to communicate to your circle and pass onto your family, this is it. Your children are counting on you.

In the first two videos, Greta makes interesting point. If ever you imagined hearing an alarm bell, your ears should be clanging with these statements…

1st video, below

Greta was puzzled by an apparent incongruity when she was 8 years old: How is it that a widely reported existential threat has not resulted in a Stop-The-Presses, all out campaign to eliminate the threat? How is it that a majority of people claim to support the cause, applaud at speeches, support the Paris Accords—and yet the burning of fossil fuels has increased and the destruction of jungles & rain forests is accelerating? The carbon budget of the Paris Accords has already been ⅔ consumed! Even worse, scientists now believe that the budget was too relaxed. Even back then (3 years ago) things were worse than we had believed.

 2nd video, below

Although Greta states it without emotion (a symptom of Asberger’s), she was surprised to find that America has climate change ‘believers’ and ‘non-believers’. Without a hint of sarcasm, she explains that in Sweden, everyone understands the facts.

Please view these videos. Is there anything in your day that is more important? I doubt it. Saving the planet is no longer a slogan. It’s our only chance at survival—and that chance is getting slimmer with each day.

Philip Raymond co-chairs CRYPSA, hosts the Bitcoin Event and is keynote speaker at Cryptocurrency Conferences. He is a top writer at Quora.

It’s not the purpose of this post to explain encryption, AES or SHA-256, but here is a brief description of SHA-256. Normally, I place reference links in-line or at the end of a post. But let’s get this out of the way up front:  

• Sept 11: Original disclosure
• Sept 11: Community skepticism
• Sept 12: Claim retracted: [announcement] [press]

One day after Treadwell Stanton DuPont claimed that a secret project cracked SHA-256 more than one year ago, they back-tracked. Rescinding the original claim, they announced that an equipment flaw caused them to incorrectly conclude that they had algorithmically cracked SHA-256.

“All sectors can still sleep quietly tonight,” said CEO Mike Wallace. “Preliminary results in this cryptanalytic research led us to believe we were successful, but this flaw finally proved otherwise.”

Yeah, sure! Why not sell me that bridge in Brooklyn while you backtrack?

The new claim makes no sense at all—a retraction of an earlier claim about a discovery by a crack team of research scientists (pun intended). The clues offered in the original claim, which was issued just one day earlier, cast suspicion on the retraction. Something fishy is going on here. Who pressured DuPont into making the retraction—and for what purpose? Something smells rotten in Denmark!

Let’s deconstruct this mess by reviewing the basic facts:

• Wall Street, financial services firm claims they have solved a de facto contest in math & logic
• They cracked the code a year ago, yet— incredibly—kept it secret until this week
• A day later (with no outside review or challenge),* they admit the year-old crack was flawed

Waitacottenpickensec, Mr. DuPont!! The flaw (an ‘equipment issue’) was discovered a year after the equipment was configured and used—but just one day after you finally decided to disclose their past discovery? Poppycock!

I am not given to conspiracy theories (a faked moon landing, suppressing perpetual motion technology, autism & vaccinations, etc)—But I recognize government pressure when I see it! Someone with guns and persuasion convinced DuPont to rescind the claim and offer a silly experimental error.

Consider the fallout, if SHA-256 were to suddenly lose public confidence…

• A broken SHA-256 would wreak havoc on an entrenched market. SHA-256 is a foundational element in the encryption used by consumers & business

• But for government, disclosing a crack to a ubiquitous standard that they previously discovered (or designed) would destroy a covert surveillance mechanism—because the market would move quickly to replace the compromised methodology.

I understand why DuPont would boast of an impressive technical feat. Cracking AES, SSL or SHA-256 has become an international contest with bragging rights. But, I cannot imagine a reason to wait one year before disclosing the achievement. This, alone, does not create a conundrum. Perhaps DuPont was truly concerned that it would undermine trust in everyday communications, financial transactions and identity/access verification…

But retracting the claim immediately after disclosing it makes no sense at all. There is only one rational explanation. The original claim undermines the interests of some entity that has the power or influence to demand a retraction. It’s difficult to look at this any other way.

What about the everyday business of TS DuPont?

If the purpose of the original announcement was to generate press for DuPont’s financial services, then they have succeeded. An old axiom says that any press is good press. In this case, I don’t think so! Despite the potential for increased name recognition (Who knew that any DuPont was into brokerage & financial services?) I am not likely to think positively of TS DuPont for my investment needs.

* The cryptographic community could not challenge DuPont’s original claim, because it was not accompanied by any explanation of tools, experimental technique or mathematical methodology. Recognizing that SHA-256 is baked into the global infrastructure banking, of commerce and communications, their opaque announcement was designed to protect the economy. Thank you, Mr. DuPont, for being so noble!

Yesterday (Sep 5, 2019), the Breakthrough Prize Foundation awarded $21.6 million US dollars to the scientists behind a stunning achievement. They imaged a black hole. Although the image was announced and released 5 months ago, the story is still unfolding.

Yesterday (Sep 5, 2019), the Breakthrough Prize Foundation awarded $21.6 million US dollars to the scientists behind a stunning achievement. They imaged a black hole. Although the image was announced and released 5 months ago, the story is still unfolding.

The Breakthrough Prize is funded by Russian-Israeli billionaire Yuri Milner. It is the highest-paying science prize for researchers in life science, math, and physics.

There are many black holes in our galaxy and some small ones in our own galactic “neighborhood” . Yet the EHT team* focused on M87, a black hole in the center of another Galaxy, 55 million light years from our solar system.

This is pretty far, but it is a massive black hole with a bright accretion disk (stuff around the event horizon), and it is orthogonal to our vantage point. How big is the M87 black hole? It is bigger than our entire solar system!

At this unfathomable distance, it is difficult to image anything smaller than an entire galaxy. But by combining data from instruments and math teams around the world, scientists released in April an actual photograph. To be precise, it is the shadow of a black hole, but it clearly shows the accretion disk, event horizon and a hole in the middle. In fact, it shows a perfect, glowing donut.

* The EHT = Event Horizon Telescope

To achieve the implausible, scientists combined data from 8 radio telescopes around the world, including two operated by the European Southern Observatory in Chile (producer of the first video, below). Although data was captured as radio waves, a team of 347 scientists pieced the information together into an actual image. What you see in the paragraph above is not an illustration based on data. It is a genuine photograph.

As you view the 1st video below, you may not feel that it is new. Even with the Big Bang in question, black holes are certain fact, and images have been circulating for years. But—until now—those were all artist’s renderings. There has never been an actual photo of a black hole. This is a first.

A web search turns up many videos about the achievement. Some are less than 2 minutes, and some are 2 hour documentaries. I like these two videos: [1] a 17 minute video documenting the effort to achieve this milestone and clearly explaining the result—and [2] an 11½ minute Ted Talk:

1. In the Shadow of the Black Hole

2. Inside the Black Hole That Made History

Each transaction into and out of a wallet is a bread crumb. Following the trail is trivial. Every day, an army of armchair sleuths help the FBI. That’s how Silk Road was brought down.

The problem is that some of that money eventually interacts with the real world (a dentist is paid, a package shipped or a candy is purchased at a gas station). Even if the real-world transaction is 4 hops before or after hitting the “anonymous” wallet, it creates a forensic focal point. Next comes a tax man, an ex-spouse or a goon.

The first article linked below addresses the state of tumblers (aka “mixers”). They anonymize an open network by obfuscating the trail of bread crumbs.

Mixers/tumblers aren’t the only way to add a layer of privacy to Bitcoin transactions. The Lightning Network spec includes an optional 17-hop onion routing (just like TOR’s 4 step onion routing). I have not yet seen the feature expressed in wallets or services, but if implemented, it will be even more private and trustworthy than a mixer, because there is no middle party to trust (by you) or squeeze (by investigators). It has the potential to makes any crypto Bitcoin even more anonymous than cash.

Certain cryptocurrencies (not Bitcoin) have anonymity baked in by design. Monero, ZCash and Dash are privacy tokens that use very different approaches to eliminate the bread crumbs. Monero appears to have one distinct advantage: Like the TOR network, it is trustless. But there are benefits to each approach.
