Las Vegas Approves The Boring Company's Underground Loop (cnet.com) 81

The Boring Company's tunnel project in Chicago is "in doubt" (according to the Chicago Tribune), while a project connecting Washington to Baltimore "is waylaid in the environmental-review process."

But it looks like Las Vegas will officially get a tunnel from Elon Musk, CNET reports, "perhaps within this year." The billionaire's Boring Company on Tuesday got the approval from the 14-member board of the Las Vegas Convention and Visitors Authority (LVCVA) to build and operate an underground loop that would carry people in autonomous electric vehicles at the city's convention center.

Musk has responded to the approval in a tweet, saying he'll make the tunnel "operational by end of year," even though the convention center's expansion won't be done until 2021, according to LVCVA's release... A LVCVA spokeswoman said in an email that the underground loop will be ready in 2021 if the contract with the Boring company is approved at LVCVA's board meeting on June 11.

The Las Vegas Sun has more details, pointing out that travellers would be carried in electric vehicles moving through two parallel tunnels, one running in each direction. And that fleet of electric vehicles "could include Tesla's Model X and Model 3 and a vehicle with capacity for about 16 people â" all manufactured by Musk. All the vehicles would be fully autonomous, meaning they won't have backup drivers, and would move at speeds of up to 50 mph."

The mayor of Las Vegas, also a member of the board, actually voted against the tunnel, calling the Boring Company "exploratory at this time" and warning that "we are considering handing over the reins of our most important industry."

Proposal For United Nations To Study Climate-Cooling Technologies Rejected (reuters.com) 241

An anonymous reader quotes a report from Reuters: A push to launch a high-level study of potentially risky technological fixes to curb climate change was abandoned on Thursday at a U.N. environmental conference in Nairobi, as countries including the United States raised objections. "Geoengineering" technologies, which are gaining prominence as international efforts to curb climate-changing emissions fall short, aim to pull carbon out of the atmosphere or block some of the sun's warmth to cool the Earth. They could help fend off some of the worst impacts of runaway climate change, including worsening storms and heatwaves, backers say. But opponents argue the emerging technologies pose huge potential risks to people and nature, and could undermine efforts to reduce greenhouse gas emissions, not least because many are backed by fossil-fuel interests. Observers at the U.N. Environment Assembly in Nairobi said the Swiss-backed proposal was rejected in part because it called for a "precautionary principle" approach to geoengineering the climate. That principle says great care must be taken in starting activities that have unclear risks for human health or the environment. The United States, Saudi Arabia and Brazil were among the strongest opponents of the proposal, with Japan also expressing reservations.

Mercury -- Not Venus -- is the Closest Planet To Earth on Average, New Research Finds (gizmodo.com) 177

That's the finding presented by a team of scientists who have published their results this week in an article in the magazine Physics Today. From a report: They explain that our methods of calculating which planet is "the closest" oversimplifies the matter. But that's not all. "Further, Mercury is the closest neighbor, on average, to each of the other seven planets in the solar system," they write. Wait -- what?

Our misconceptions about how close the planets are to one another comes from the way we usually estimate the distances to other planets. Normally, we calculate the average distance from the planet to the Sun. The Earth's average distance is 1 astronomical unit (AU), while Venus' is around 0.72 AU. If you subtract one from the other, you calculate the average distance from Earth to Venus as 0.28 AU, the smallest distance for any pair of planets. But a trio of researchers realized that this isn't an accurate way to calculate the distances to planets. After all, Earth spends just as much time on the opposite side of its orbit from Venus, placing it 1.72 AU away.

One must instead average the distance between every point along one planet's orbit and every point along the other planet's orbit. The researchers ran a simulation based on two assumptions: that the planets' orbits were approximately circular, and that their orbits weren't at an angle relative to one another.

The Opportunity Rover's Final Photo of Mars (cnn.com) 48

pgmrdlm shares a report from CNN: Last May, Opportunity took a look around Perseverance Valley on the inner slope of Endurance Crater's western rim. The valley is about the length of two football fields and it's full of descending shallow troughs. Ironically, Perseverance Valley became Opportunity's final resting place when a planet-encircling dust storm took over Mars in June, blocking the sun from reaching the rover's solar panels. Engineers lost contact on June 10 and persistently sent more than a thousand signals and commands to the rover over eight months until they realized the mission was over on February 13. But before those dark days, Opportunity acted like a tourist, snapping 354 photos between May 13 and June 10 that would create one last beautiful panorama of the place it will forever call home. "This final panorama (embedded in the report) embodies what made our Opportunity rover such a remarkable mission of exploration and discovery," said Opportunity project manager John Callas of NASA's Jet Propulsion Laboratory. "To the right of center you can see the rim of Endeavour Crater rising in the distance. Just to the left of that, rover tracks begin their descent from over the horizon and weave their way down to geologic features that our scientists wanted to examine up close. And to the far right and left are the bottom of Perseverance Valley and the floor of Endeavour crater, pristine and unexplored, waiting for visits from future explorers."

Death Metal Music Inspires Joy Not Violence, Study Finds (bbc.com) 170

An anonymous reader quotes a report from the BBC: I've had one desire since I was born; to see my body ripped and torn. The lyrics of death metal band Bloodbath's cannibalism-themed track, Eaten, do not leave much to the imagination. But neither this song -- nor the gruesome lyrics of others of the genre -- inspire violence. That is the conclusion of Macquarie University's music lab, which used the track in a psychological test. It revealed that death metal fans are not "desensitized" to violent imagery. The findings are published in the Royal Society journal Open Science. How do scientists test people's sensitivity to violence? With a classic psychological experiment that probes people's subconscious responses; and by recruiting death metal fans to take part. The test involved asking 32 fans and 48 non-fans listen to death metal or to pop whilst looking at some pretty unpleasant images.

Lead researcher Yanan Sun explained that the aim of the experiment was to measure how much participants' brains noticed violent scenes, and to compare how their sensitivity was affected by the musical accompaniment. To test the impact of different types of music, they also used a track they deemed to be the opposite of Eaten. "We used 'Happy' by Pharrell Williams as a [comparison]," said Dr Sun. Each participant was played Happy or Eaten through headphones, while they were shown a pair of images -- one to each eye. One image showed a violent scene, such as someone being attacked in a street. The other showed something innocuous -- a group of people walking down that same street, for example. "If fans of violent music were desensitized to violence, which is what a lot of parent groups, religious groups and censorship boards are worried about, then they wouldn't show this same bias. "But the fans showed the very same bias towards processing these violent images as those who were not fans of this music."

Radioactive Particles From Huge Solar Storm Found In Greenland (theguardian.com) 54

Traces of an enormous solar storm that battered the atmosphere and showered Earth in radioactive particles more than 2,500 years ago have been discovered under the Greenland ice sheet. The Guardian reports: Scientists studying ice nearly half a kilometer beneath the surface found a band of radioactive elements unleashed by a storm that struck the planet in 660BC. It was at least 10 times more powerful than any recorded by instruments set up to detect such events in the past 70 years, and as strong as the most intense known solar storm, which hit Earth in AD775. The discovery means that the worst-case scenarios used in risk planning for serious space weather events underestimate how powerful solar storms can be.

Raimund Muscheler, a professor of quaternary sciences at Lund University in Sweden, and his team analyzed two ice cores drilled from the Greenland ice sheet and found that both contained spikes in isotopes of beryllium and chlorine that date back to about 660BC. The material appears to be the radioactive remnants of a solar storm that battered the atmosphere. The scientists calculate that the storm sent at least 10 billion protons per square centimeter into the atmosphere. "A solar proton event of such magnitude occurring in modern times could result in severe disruption of satellite-based technologies, high frequency radio communication and space-based navigation systems," they write in Proceedings of the National Academy of Sciences.

Facebook Sues Over 'Data-Grabbing' Quizzes (bbc.com) 39

Facebook is suing Andrew Gorbachov and Gleb Sluchevsky, of Ukraine, who worked for a company called Web Sun Group that developed "data-grabbing" quizzes for its social media site. The malicious quiz apps were used to harvest thousands of users' profile data. "The firm says anyone who wanted to take the quizzes was asked to install browser extensions, which then lifted data ranging from names and profile pictures to private lists of friends," reports the BBC. "These were installed about 63,000 times between 2016 and October 2018, it says." From the report: The quizzes, with titles such as "What does your eye color say about you?" and "Do people love you for your intelligence or your beauty?", gained access to this information via the Facebook Login system -- which enables connections between third party apps and Facebook profiles. While the system is intended to verify that such connections are secure, in this case, Facebook says, users were falsely told the app would retrieve only a limited amount of public data from their profiles. "In total, defendants compromised approximately 63,000 browsers used by Facebook users and caused over $75,000 in damages to Facebook," the company said in court documents first published by online news site The Daily Beast. The documents accuse the two men of breaking US laws against computer hacking as well as breaching Facebook's own terms of use.

Salon: Republicans Are Launching Fake Local News Sites To Spread 'Propaganda' (salon.com) 539

"The Tennessee Star claims to be the 'most reliable' online local paper in the state," reports Salon. "In fact it's just a GOP front." An anonymous reader quotes their report:
An investigation by the fact-checking outlet Snopes found that several new local news websites are actually being launched by Republican consultants whose company is funded in part by the candidates the sites cover. Politico first reported last year that Tea Party-linked conservative activists Michael Patrick Leahy, Steve Gill and Christina Botteri were behind the "Tennessee Star," a website that purported to be a local news website but mostly posted content licensed from groups linked to big Republican donors. Snopes discovered that the trio has since launched similar sites in other battleground states ahead of the 2020 elections: the Ohio Star and the Minnesota Sun...

The group behind the sites does not appear content with just three outlets. According to Politico, Leahy has purchased domain names associated with Missouri, New England, the Dakotas, Michigan, North Carolina, Pennsylvania, Virginia and Wisconsin, most of which are electoral battleground states that will be vital in 2020.

Kathleen Bartzen Culver, who heads the Center of Journalism Ethics at the University of Wisconsin at Madison, told Snopes that political operatives are free to launch their own news platforms, but it's a problem if they are trying to deceive readers into believing the sites are nonpartisan local news. "I have no problem with advocacy organizations creating content that reinforces the positions they take on public policy issues on the left, right or center. The issue comes in when they're not transparent about that advocacy," Culver said... "The information sphere is so polluted right now that the average citizen has trouble telling what is real and what is not," Culver told Snopes. "I find that very troubling within a democracy."

Google's Sidewalk Labs Thinks a Reinvented Awning Will Fix Toronto's Winter (engadget.com) 61

One of the prototypes Alphabet's Sidewalk Labs is working on for its planned neighborhood on Toronto's waterfront is a hexagonal paving system. "The slabs are porous and heated, which may keep snow and ice at bay without salting," reports Engadget. "They're easy to replace, and include LED lights that can, for instance, help direct traffic flow during construction or mark street closures." From the report: Sidewalk will also demonstrate what it's calling a Building Raincoat, an awning it says will help protect sidewalks from wind, rain, sun and snow to make outdoor space usable throughout the year. It attaches to the sides of buildings and is fixed to ground anchors. It's made from a durable, lightweight and transparent plastic called ETFE (Ethylene Tetrafluoroethylene).

In addition, Sidewalk will have a number of art installations at the public event, which "use lighting, projection mapping, mud and other techniques to reflect on relationships between humans and animals in public space, and the broader connection of ecology and urbanism." Some of the works will be projected onto the awning. Along with the prototypes, Sidewalk will discuss some of its broader ideas about how to make its neighborhood livable and accessible, in part through affordable housing and its transit system.

Astronomer Finds Potential Furthest Object In Solar System 58

Prominent astronomer Dr Scott Sheppard, of the Carnegie Institution for Science in Washington D.C., has discovered a new object in the distant reaches of our solar system and given it the name FarFarOut. "At 140 times further away from the sun than our own planet is, the newly identified body -- if its discovery is confirmed -- will become the furthest known object in our solar system," reports The Guardian. Sheppard's discovery was made after his team was analyzing astronomical data to track down Planet Nine, a yet-to-be-discovered body thought to have 10 times the mass of Earth. From the report: Sheppard said he made the discovery of FarFarOut when a lecture he was due to give on his team's work was postponed and he went back to analyzing his data. He said FarFarOut was somewhat mysterious. "It is very faint; it is on the edge of our ability to detect it," Sheppard said. "We don't know anything about the orbit of this object, we just know it is far, far out." Sheppard said further observations were in the offing to shed more light on the find. The current record holder -- a dwarf planet at 120 times the Earth-sun distance -- was named merely FarOut when it was spotted by the same team in December last year.

Netflix Buys Rights To Stream Chinese Sci-Fi Blockbuster 'The Wandering Earth' (npr.org) 214

An anonymous reader writes from a report via NPR: Netflix announced this week that it has acquired the rights to stream Chinese sci-fi blockbuster "The Wandering Earth," which has already grossed more than $600 million globally and hit number two in the all-time Chinese box office rankings since it was released in theaters Feb. 5. Netflix will translate the movie into 28 languages and release it in more than 190 countries. The movie, based on a short story by Hugo award winner Liu Cixin (author of "Three Body Problem" and "Ball Lighting") is set in a distant future in which the earth is about to be devoured by the sun. Using propulsive engines, humans turn earth into a spaceship and try to launch it out of the solar system and the planet is saved by a Chinese hero (rather than American ones as typically seen in Hollywood sci-fi movies.)

For China's film industry, the release marks a major milestone. "Filmmakers in China see science fiction as a holy grail," Raymond Zhou, an independent critic, told The New York Times. "It's like the coming-of-age of the industry." Two sci-fi movies, "The Wandering Earth" and "Crazy Alien," which is also inspired by Liu's work, topped this Chinese New Year movie season. Inkoo Kang wrote at Slate that the film "understands what American blockbusters are still loath to admit: Responding to climate change will pose infrastructural challenges on a massive order and require drastic measures on a planetary scale. Perhaps it takes a country like China, which is accustomed to a manic rate of construction and grandness of organizational possibility, to seriously consider how dramatically humanity will have to reimagine our ways of life to survive such a catastrophic force."

Could 'Oumuamua Be A Fluffy Radiation-Driven Icy Fractal From Another Star System? (syfy.com) 90

"Oumuamua, the first object ever seen passing through our solar system from interstellar space, was thought to be emitting gas like a comet to explain its weird motion," reports Syfy Wire, "but a new idea is that the comet is just very, very porous."

Astronomer Phil Plait writes: It was hard to tell what it was; it was too small, faint, and far away to get good observations, and worse, it was only seen on its way out, so it was farther from us literally every day. Then another very weird thing happened: More observations allowed a better determination of its trajectory, and it was found that it wasn't slowing down fast enough. As it moves away, the Sun's gravity pulls on it, slowing it down...but it wasn't slowing down enough. Some force was acting on it, accelerating it very slightly... A new paper has come out that might have a solution, and it's really clever. Maybe 'Oumuamua's not flat. Maybe it's fluffy... [And thus moved by the force of sunlight giving it a tiny push]

When stars are very young, they have a huge disk of material swirling around them; it's from this material that planets form. Out far from the star, where temperatures in the disk are cold, teeny tiny grains of dust and water ice can stick together in funny shapes, creating fractals... Materials made in a fractal pattern can be very porous, and in fact out in that protoplanetary disk around a young star, physical models show that objects can grow fractally until they're as big as 'Oumuamua, and have those extremely low densities needed to account for its weird behavior. So 'Oumuamua doesn't have to be a spaceship. It just has to be a snowflake! A three-dimensionally constructed phenomenally porous low-density snowflake... [T]he new paper suggests it came from a nearby star, and one that's relatively young (less than 100 million years). It formed out in the disk, and got ejected somehow, likely from a planet forming nearby giving it a boost from its gravity.

"I certainly hope we find more beasties like this one," Plait writes. "They can tell us so much about how planets form in other star systems, which is pretty hard to figure out from dozens or hundreds of light years away.

"It's a lot easier when they obligingly send bits of their building materials to us."

Earth's Atmosphere Extends Much Farther Than Previously Thought (newatlas.com) 67

Contrary to general belief that Earth's atmosphere stops a bit over 62 miles from the surface, a new study based on observations made over two decades ago by the joint US-European Solar and Heliospheric Observatory (SOHO) satellite shows that it actually extends as far 391,000 miles (630,000 km) or 50 times the Earth's diameter. This makes the Moon a very high altitude aircraft. From a report: Launched on December 2, 1995 atop an Atlas IIAS launcher from Cape Canaveral Air Force Station in Florida, SOHO is parked in the first Lagrange point (L1) 930,000 miles (1.5 million km) from Earth where it has carried out studies of the Sun and the solar winds, and will continue to do so until at least 2020. From this vantage point, the observatory's Solar Wind Anisotropie (SWAN) instrument is able to measure the presence of hydrogen by looking at the Lyman-alpha line in the solar spectrum. And what works for the Sun, works for Earth. By turning SWAN on the Earth at the right times of the year, SOHO was able to detect hydrogen atoms from the atmosphere and measure how far out they extend into what space scientists call the geocorona. While the existence of the geocorona is well known -- the telescope set up by the Apollo 16 astronauts on the Moon even photographed it -- no one was sure how far out it reaches until now.

By looking at data collected by SOHO in the mid 1990s, scientists from Russia's Space Research Institute and elsewhere were able to work out the extent and density of the geocorona. What they found was that sunlight on the day side of the Earth compresses the hydrogen until it reaches a density of 70 atoms per cubic cm at an altitude of 37,000 miles (60,000 km), and on the night side it can expand out until it has a density of only 0.2 atoms per cubic cm at the distance of the Moon's orbit. According to the study leader Igor Baliukin, the geocorona is so tenuous that it poses no hazard to astronauts or spacecraft.

DC Cancels Comic Where Jesus Learns From Superhero After Outcry (theguardian.com) 348

AmiMoJo writes: A new comics series in which Jesus Christ is sent on "a most holy mission by God" to learn "what it takes to be the true messiah of mankind" from a superhero called Sun-Man, has been cancelled by DC Comics. The move follows a petition that called it "outrageous and blasphemous". The Second Coming series, from DC imprint Vertigo, was due to launch on 6 March. Written by Mark Russell and illustrated by Richard Pace, its story followed Jesus's return to Earth. "Shocked to discover what has become of his gospel," he teams up with a superhero, Sun-Man, who is more widely worshipped than him.

An Insect-bot Mimics Desert Ants by Looking at the Sky To Navigate (technologyreview.com) 17

From a report: A new robot can navigate without GPS, using the same light-sensing abilities as desert ants. Desert ants survive in searingly hot conditions in the Sahara. They sometimes have just a few minutes to forage for food before they risk burning to death. As a result, they are very efficient navigators, using bands of polarized light, invisible to humans, to get around. They also carefully count their steps. These two tactics help to keep them alive. AntBot: The bot, described this week in Science Robotics, is fitted with UV light sensors that can detect polarized light from the sun. This is known as a "celestial compass" and is designed to mimic the way desert ants see the sun's light. This helps it work out the direction it's going in. The robot also counts its steps, much like its desert muse. In tests, it successfully managed to complete an outdoor homing task, where it was required to go to several checkpoints and then return to a fixed location within a range of 14 meters.

How India's Single Time Zone Is Hurting Its People (bbc.com) 175

"The BBC reports on the detrimental effects of all of India being in one time zone since British Colonial rule," writes Slashdot reader dryriver. From the report: India stretches 3,000km (1,864 miles) from east to west, spanning roughly 30 degrees longitude. This corresponds with a two-hour difference in mean solar times -- the passage of time based on the position of the sun in the sky. The U.S. equivalent would be New York and Utah sharing one time zone. Except that in this case, it also affects more than a billion people -- hundreds of millions of whom live in poverty. The school day starts at more or less the same time everywhere in India but children go to bed later and have reduced sleep in areas where the sun sets later. An hour's delay in sunset time reduces children's sleep by 30 minutes. Using data from the India Time Survey and the national Demographic and Health Survey, [Cornell University Economist] Maulik Jagnani found that school-going children exposed to later sunsets get fewer years of education, and are less likely to complete primary and middle school. He found evidence that suggested that sunset-induced sleep deprivation is more pronounced among the poor, especially in periods when households face severe financial constraints. "This might be because sleep environments among poor households are associated with noise, heat, mosquitoes, overcrowding, and overall uncomfortable physical conditions. The poor may lack the financial resources to invest in sleep-inducing goods like window shades, separate rooms, indoor beds and adjust their sleep schedules," he told me.

Incredible New Animation Shows The Ferocious Power of a Solar Flare (astroengine.com) 42

NASA and the National Science Foundation helped fund something amazing. Slashdot reader astroengine writes: For the first time, scientists have created a computer model that can simulate the evolution of a solar flare, from thousands of miles below the photosphere to the eruption itself in the lower corona -- the sun's multimillion degree atmosphere. And the results are not only scientifically impressive, the visualization is gorgeous....

[W]ith increasingly-sophisticated solar observatories (such as NASA's Solar Dynamics Observatory), we are getting an ever more detailed look at what's going on inside the sun's deep atmosphere and, with improvements of theoretical models and increases in computer processing power, simulations of the corona are looking more and more like the real thing... Rather than forcing their simulation to generate flares, they re-enacted the conditions of the sun that were observed and just let their simulation run to create its own flares. "Our model was able to capture the entire process, from the buildup of energy to emergence at the surface to rising into the corona, energizing the corona, and then getting to the point when the energy is released in a solar flare," said NCAR scientist Matthias Rempel in a statement. "This was a stand-alone simulation that was inspired by observed data. "

They're calling it "a three-dimensional radiative magnetohydrodynamic simulation of a solar flare," and Discover magazine breaks down the colors in the image -- for example, green shows the hottest plasma, with temperatures over 10 million K (or nearly 18 million F).

"A single flare can release the equivalent of millions of hydrogen bombs all going off at the same time."

Party Is Over For Dirt-Cheap Solar Panels, Says China Executive (reuters.com) 170

The president of a top-10 maker of solar panels said the global solar power industry is about to lose a major competitive windfall as prices of Chinese-made solar panels begin to recover after a collapse last year. "The party is definitely over," said Eric Luo, president of China's GCL System Integration Technology Co. Reuters reports: Solar panel prices tumbled around 30 percent last year after China, the world's largest producer, cut subsidies to shrink its bloated solar industry, pushing smaller manufacturers to the brink of collapse. To raise cash and stay afloat, manufacturers cleared inventory and diverted sales offshore, sending prices into a downward spiral - offering up a windfall for solar power generators and investors in solar farms.

Luo, speaking to Reuters at the World Economic Forum in the Swiss ski resort of Davos this week, said GCL's vertically integrated business model cushioned it from the downturn in prices as its solar farms benefited from cheaper panels. The pain will mostly be felt by smaller Chinese producers, which lack international supply chains, triggering industry consolidation or forcing them to close, he added. Luo said solar panel prices were already stabilizing and he expected them to rebound by 10 to 15 percent as the Chinese industry consolidates over the next year or two.
Luo also said that China was getting to the point where the solar industry could operate without any form of subsidy. Northwest China, where the sun is more plentiful and land is less expensive, has already reached that point, he said.

Weird Orbits of Distant Objects Can Be Explained Without Invoking a 'Planet Nine' (space.com) 61

schwit1 shares a report from Space.com: The weirdly clustered orbits of some far-flung bodies in our solar system can be explained without invoking a big, undiscovered "Planet Nine," a new study suggests. The shepherding gravitational pull could come from many fellow trans-Neptunian objects (TNOs) rather than a single massive world, according to the research. "If you remove Planet Nine from the model, and instead allow for lots of small objects scattered across a wide area, collective attractions between those objects could just as easily account for the eccentric orbits we see in some TNOs," study lead author Antranik Sefilian, a doctoral student in the Department of Applied Mathematics and Theoretical Physics at Cambridge University in England, said in a statement.

The duo's modeling work suggests that the strength-in-numbers explanation does indeed work -- if the mass of the Kuiper Belt, the ring of bodies beyond Neptune, is a few to 10 times that of Earth. This is a pretty big "if," given that most estimates peg the Kuiper Belt's mass at less than 10 percent that of Earth (and one recent study put the figure at 0.02 Earth masses). But other solar systems are known to harbor massive disks of material in their outer reaches, Sefilian and Touma noted. And our failure to spot one around our own sun doesn't mean it doesn't exist, they stressed.
The new study has been accepted for publication in the Astronomical Journal.

Tron's CEO Wants To Use Blockchain Games and BitTorrent To Decentralize the Internet (venturebeat.com) 79

From a report: Last summer, Justin Sun, the 28-year-old CEO of Tron acquired BitTorrent, the 15-year-old file-sharing company that is one of the biggest decentralized networks in existence for $140 million. He wanted to take advantage of blockchain, the decentralized ledger that is both secure and transparent, and combine it with the decentralized file-sharing app, offering crypto rewards to those who share their computers for file sharing. And this week, Sun appeared on stage with former basketball star Kobe Bryant at the NiTron Summit, which drew more than 1,000 attendees. Tron has also created a $100 million fund to convince game developers to make games that use Tron's protocol and its TRX cryptocurrency. The promise is to create a crypto network that is both fast -- at 2,000 transactions per second -- and reliable.

I interviewed Sun backstage at the NiTron Summit, where he said he wanted his company to become the major blockchain platform that could one day be the decentralized alternative to the centralized internet networks of Google, Facebook, and Apple. But to make that happen, Sun has to get mainstream people like the 100 million BitTorrent users to trust cryptocurrency, even after a coin market slide that has wiped out billions in value, including taking Tron's TRX market value down from near $20 billion to $1.6 billion today.
