Woz’s Technological Optimism Suggests Promise for Bitcoin, Blockchain 9 5425

The earliest Macintosh PowerBook was chunky and dark gray. It featured a built in trackball, where the touchpad is on today’s Macbook, and little rotating peg legs to elevate the keyboard at an ergonomic tilt. The screen was black and white. You could open it on your desk at school, and tuck it into its special carrying case to sling it over your shoulder when Mom came to pick you up.

Going to school with Steve Wozniak’s kids in Los Gatos, California, meant having special access to cutting edge technology, like the Macintosh PowerBook in 1992. Along with five other students from our small school in the Santa Cruz mountains, I went to after school classes at Woz’s office to learn about Apple computers and emerging technology.

The first day, Woz taught us to dismantle and reassemble a desktop Macintosh, showing us all the pieces and what they did, with diagrams on the whiteboard. We learned the difference between random access memory (RAM) and the storage space on a hard disk, between a hard disk and a floppy disk. We learned how to navigate the innovative GUI that used windows (while PCs were still using DOS) to access the Apple utilities and adjust the settings for peak performance.

A great advocate for the intelligence and capacity of children, Woz challenged us with sophisticated knowledge and trusted us with expensive equipment, eager to see what creative uses we would put them to. He showed us the first version of Adobe Photoshop, a new technology that shook the public into doubting the integrity of photographs. Along with it, we had early model digital cameras called Canon XapShots, which used tiny floppy disks to store around 50 pictures at a time. The day he brought in America Online version 1.0, we were ecstatic that we could chat with each other from different rooms.

Woz was childlike himself, especially in his enthusiasm for developing technology. When laser pens were new, you could always find one clipped to the collar of his Hard Rock Cafe tshirt. He seemed to like them more for playing tricks on people than for any practical purpose.

Early Techs Championed by Woz Became Familiar Names

Most of the technologies Woz championed have evolved. Some went big. As dial up AOL gave way to internet browsers like Netscape, I remember sitting in our middle school’s Wozniak Library Media Center learning how to use a world wide web page called Yahoo!, the novelty of which I put to work looking up David Letterman’s recent Top 10 lists.

America Online set the original chatroom model, complete with primitive emojis. It grew so big that in 2000, the year we kids were graduating high school, it bought Time Warner for $165 billion and became AOL Time Warner, then the world’s biggest media conglomerate. Now, estranged from Time and Warner after a decade and a half of new mergers, AOL is part of the Verizon subsidiary Oath, which also owns Yahoo! and, believe it or not, Netscape, which is still around.

The success of Photoshop, of course, positioned Adobe to set industry standards, now untouchable as king of the Silicon Valley’s creativeware. Macintosh PowerBooks evolved into Macbooks. Digital photography sure became a thing. And there are exceptions, too. Those laser pens, well, occasionally you still see someone using one to disrupt their cat.

Woz on Bitcoin

Wozniak hasn’t taken his finger off the pulse of emerging tech. Still full of wonder for the promise and possibility of technological advances, he’s been outward about his enthusiasm for Bitcoin, calling it “pure digital gold,” and placing his faith ardently in its mathematical integrity.

“I believe so strongly in mathematics and purity and science as defining the world,” he told CNBC in June.

“Bitcoin is mathematically defined. There’s a certain quantity of Bitcoin,” he said, “and it’s pure. There’s no human running it. There’s no company running it, and it’s just going and going, and growing and growing, and surviving! That, to me, says something that is about—something that is natural. And nature is more important than all our human conventions.”

His journey with Bitcoin is well documented. He tried to buy some around $70, ended up not getting any until they hit $700. Then he lost a few to fraud, and when prices soared “way up in the sky,” he said he “got scared, and sold everything but one Bitcoin.”

Woz stresses that he isn’t an investor. Still a man who loves laughter, he puts a premium on happiness, not wealth, and only holds his single Bitcoin for the sake of experimentation. “Part of my happiness is not to have worries, so I sold it all — just got rid of it — except just enough to still experiment with,” he told CNBC last year.

He said he agrees with Twitter founder and Square CEO Jack Dorsey, that Bitcoin could be the first global currency. At New York’s Consensus, a blockchain conference last May, Dorsey said “the internet is going to have a native currency so let’s not wait for it to happen, let’s help it happen… I don’t know if it will be Bitcoin but I hope it will be.”

Woz responded: “I buy into what Jack Dorsey says, not that I necessarily believe it’s going to happen, but because I want it to be that way.”

By contrast, Woz has called federal fiat currency “kind of phony.”

…And on Blockchain

But Bitcoin isn’t blockchain. It’s just the first and most well known use of blockchain technology. Last month at New York’s NEX technology conference, Woz called blockchain a bubble, similar to the dotcom hype bubble of the early aughts. “It was a bubble, and I feel that way about blockchain,” he said on stage.

“Blockchain in all forms is so popular and being studied by so many people,” he previously said in June’s CNBC interview. “It may be long term. I do see it, as you said, as a bubble… There’s a huge amount of interest in it right now, but things aren’t going to change that rapidly. That’s what the internet bubble was about.”

When asked how long he expects it to take for blockchain to gain widespread traction, he referred to the lag between the dotcom bubble and today, when we’ve finally realized many of the dotcom era dreams: “I’m going to give it 10-15 years.”

Part of the reason for this is human adjustment to new technology. “People have to have their mindset change,” he said. “Culture and tradition, and status quo and the way things are doesn’t change that rapidly, instantly, when it’s that huge.”

His faith in blockchain appears to be mixed. But in a seeming contradiction, Woz has suggested Ethereum could be the next Apple. “Ethereum interests me because it can do things and because it’s a platform,” he said at a May tech conference in Vienna.

Woz’s view of Bitcoin as solid gold but blockchain as a bubble is the inverse of that held by Jack Ma, chairman of China’s Alibaba and its fintech affiliate Ant Financial. Last month Ma said that the “technology itself isn’t the bubble, but Bitcoin likely is.”

Bubble or No, the Future Still Seems to be Blockchain

Which way is it? Is Bitcoin the bubble while blockchain is solid, as Jack Ma says, or the other way around, as Woz indicates?

Woz’s hope for Bitcoin as the pure-form currency of the future could prove misplaced if demand for it suddenly falls off. Blockchain, meanwhile, has myriad potential uses in finance, logistics, travel, even the art world. Developers and entrepreneurs are testing the mettle of this new technology with fervor and abandon. If we’ve learned from the dotcom bubble not to bet all our chips on untested technology, we can watch it develop steadily, as the internet did around the turn of the century. And even if the hype around blockchain is a bubble, Woz is probably right about the technology’s ultimate staying power.

To say the least, he’s seen a lot of technologies come and go. Sometimes, like the novelty laser pens of the late 1990s, new tech is just a fun experiment. But Woz’s enthusiasm for Bitcoin and measured interest in blockchain platforms like Ethereum is an indicator. A mathematically pure ledger system that governs transactions with transparency and automation holds emergent promise for the childlike optimist in any of us, much the way the Macintosh PowerBook did in 1992.

Freelance Terrorist Carried Out Hundreds of Bomb Threats in Exchange For Bitcoin 45 7071

An American-Israeli teen is sentenced to a decade in prison after a Tel Aviv court convicted him for a series of fake bomb threats he carried out in exchange for Bitcoin.

The 19 year old began making threats professionally at the age of 16. He is convicted only for crimes committed while over the age of 18. These include making false threats and reports, extortion, money laundering, and conspiracy to commit a crime.

While the Israeli courts withheld the defendant’s identity because some of his alleged crimes occurred while he was a minor, the Guardian identified him as Michael Kadar at the time of his arrest. He was originally indicted for over 2,000 bomb threats, carried out between 2015 and 2017.

Kadar Targeted Children and Jewish Community Centers

The targets of Kadar’s threats included Jewish community centers, the Israeli Embassy in Washington DC, elementary schools, shopping centers, hospitals, law enforcement agencies, airports and airlines.

A threat to an El-Al flight resulted in the deployment of fighter jets for an escorted emergency landing; another threat to a Canadian airport left six people injured during emergency disembarkment; a Virgin flight dumped eight tons of fuel before landing because of a threat; and another threat went to a plane carrying the Boston Celtics.

Kadar also targeted Republican Delaware state senator Ernesto Lopez, who he threatened with blackmail and the murder of his daughter. After Lopez ignored the demands, Kadar ordered drugs to have sent to Lopez’s residence.

Dealing Terror From Mom and Dad’s Apartment

His reign of terror operated from his parent’s fifth floor apartment near the beach in a posh neighborhood in Ashkelon, about 30 miles south of Tel Aviv. But his threats landed in over a dozen countries, including Ireland, New Zealand, Germany, Denmark, Great Britain, Belgium, Australia, Norway, Argentina, Israel, the United States, and Canada.

“One can easily imagine the terror, the fear and the horror that gripped the airplane passengers who were forced to make an emergency landing, some of whom were injured while evacuating the plane,” read the verdict by judge Zvi Gurfinkel, “and the terrified panic caused when there was a need to evacuate pupils from schools because of fake bomb threats.”

The Judge also divulged Kadar’s fees for his services: $40 for a threatening phone call to a private residence, $80 for a bomb threat to a school, and $500 for an airplane scare. Kadar operated on the dark net and disguised his IP address, using a powerful self-installed antenna to tap into remote networks, and software to mask his voice. According to an indictment filed against him in Florida, he spent some of his calls going into graphic detail threatening the deaths of children in American Jewish centers.

A Small Fortune in Bitcoins

At the time of his arrest, Kadar had amassed around 184 Bitcoins for such services—about half a million dollars at the time, and closer to $680,000 today. He also dealt in bomb making manuals, drugs, and child pornography.

Kadar is the son of an American mother, and his father is an Israeli engineer, and has dual citizenship. The US Department of Justice has also indicted Kadar for 32 crimes, including hate crimes, cyberstalking, giving false information to the police, and making threatening phone calls to around 200 institutions. A separate indictment also accuses Kadar of threatening the children of a former CIA and Pentagon official with kidnapping and murder, and links him to over 245 threatening calls.

When Kadar was arrested, he tried to escape by grabbing a pistol from a police officer, but was wrestled to the ground. Thursday’s conviction follows a cooperative investigation by the FBI and Israeli authorities, who have not been able to recover Kadar’s Bitcoins.

Teen’s Mother Calls Conviction ‘Cruel’

Kadar’s mother spoke outside the courtroom after her son’s sentencing, saying “This is the most cruel, cruel thing in the world. I’m very sorry, but I am ashamed that the country acts this way.” She insisted that her son needed treatment, not prison.

In an earlier interview she told Israeli TV her sun was suffering from a brain tumor, which made school difficult for him. Because of this and his autism, Kadar was homeschooled.

Defense lawyer Shira Nir said these conditions made Kadar unfit to stand trial, as he could not distinguish right from wrong. A medical panel confirmed the defendant’s autistic condition, but concluded he was capable of understanding the consequences of his actions. Judge Gurfinkel said Kadar’s conditions were taken into account, lessening the sentence from 17 years in prison to 10.

Bitcoin Uses As Much Energy As Austria, Could Add 2°C to Earth’s Atmosphere 2,187 14286

Bitcoin mining, it turns out, damages the earth more than more traditional environmental assaults like actual mineral mining.

According to a paper published Monday in Nature Sustainability, the power-hungry Bitcoin mining process consumes more than triple the amount of energy needed to mine the equivalent amount of gold, more than quadruple what’s needed for copper, and more than double what it takes to mine platinum.

Other coins didn’t fare much better. By their measurements, Ethereum and Litecoin consume 7 megajoules of electricity to produce the equivalent of $1, the same energy expenditure as copper mining but more than that of platinum or gold. Monero eats up 14 megajoules to produce $1.

Naturally, these measurements refer to the notoriously variable dollar valuations of such tokens. “While the market prices of the coins are quite volatile,” write researchers Max J. Krause and Thabet Tolaymat, “the network hashrates for three of the four cryptocurrencies have trended consistently upward, suggesting that energy requirements will continue to increase.”

Bitcoin’s Growing Electricity Bill is Bigger Than Some Countries

We’ve long known that Bitcoin is unsustainable. In a 2015 article for Motherboard, Christopher Malmo pointed out that a single Bitcoin transaction used 5,033 times as much energy as a Visa swipe, and could power 1.5 American homes for a day.

The electricity used to crunch Bitcoin code—and its environmental cost—has been growing with its increasing popularity. Digiconomist’s Bitcoin Energy Consumption Index shows Bitcoin currently consuming 73.12 terawatt hours (or 263.232 billion megajoules) of electricity annually. To put that in context, it’s comparable to the amount of energy it takes to power Austria for a year.

That means there are 175ish countries on earth using less energy than Bitcoin (to say nothing of crypto on the whole), while 66 countries consume less energy per capita than one Bitcoin transaction (it takes 94 thousand kilowatt hours of electricity to mine a single Bitcoin).

Iceland, a major hub of Bitcoin mining farms, spends nearly as much energy on Bitcoin as it does powering its residential homes. In this case, the damage is mitigated because most of Iceland’s power comes from renewable energy.

Canada’s Bitcoin emissions are also on the lower end due to renewable energy sources. They’re using this to court mining companies from China, where mining emissions are about four times that of Canada’s. Montreal International attracts foreign investment by calling Quebec the land of “green bitcoin”. This has caught the eye of some Chinese mining companies looking to go overseas as the Chinese government has discouraged expansion and shut down some mining operations altogether.

Depending on Bitcoin’s growth, some have projected that it could use as much energy as the entire world by 2020.

Digital Currency Has a Real Carbon Footprint

Krause’s and Tolaymat’s research reminds us of the sobering reality that all this invisible wealth has real world costs.

For the 30 months they measured between January 2016 and June 2018, they estimate their four featured tokens collectively belched out at least 3 million tons of CO2 emissions, possibly as much as 15 million tons.

These findings follow another study, published last month, which determined Bitcoin alone could add two degrees Celcius to global warming within the next three decades. That’s enough to raise ocean acidity by 29 percent.

Solving Bitcoin’s Energy Consumption Crisis

So what is the solution? If the world were to switch to 100 percent renewable energy overnight, the problem would be moot. But we can’t hold our breath for that. There could be ways of incentivizing clean energy so greener mines reap more coins, or of implementing clean energy in other ways.

It’s also possible to adopt less computationally intensive mining algorithms so the mining computers don’t guzzle as much juice. This would disappoint a lot of old school Bitcoiners who have invested in hardware, but their feelings don’t really outweigh that 2 degrees celcius that everyone will have to live with (or die by).

Whatever the best solution turns out to be, something needs to change soon. Bitcoin is growing up, and it’s time for it to mature into something more sustainable.
