Max Keiser: Bitcoin’s First Function Is to Clean Up the Mess Left by Fiat – Cointelegraph

Posted: December 15, 2019 at 12:43 am

International journalist and media defender of Bitcoin Max Keiser gave a presentation at Labitconf in Montevideo, Uruguay, in which he explained the impact that cryptocurrencies generate in the global scenario and particularly in the Latin American region.

With a talk entitled "Why Bitcoin Matters in Emerging Markets," Keiser took the stage in his casual style, with a sports jacket and shorts, but mainly with a very critical tone towards trust money and the traditional economic and financial system.

Keiser stressed that Bitcoin's first function is to clean up the mess left in the world by fiat money. One of the points he highlighted during the presentation was: "The inherent violence of fiat money must be replaced by the peaceful nature of Bitcoin."

On the other hand, he noted that politicians in the United States are beginning to take into account what cryptocurrencies are all about, and quoted Representative Brad Sherman, who had acknowledged that Bitcoin's purpose is to take their power away.

For Keiser, "Bitcoin is the currency of a global revolution and the nightmare of trust money," as he put it during Labitconf, it's resistance money."

On the other hand, he said that when we talk about regulations and regulators, we have to bear in mind that these regulators are paid in fiat money.

Keiser also took the opportunity to talk about Argentina, saying that Argentina is a good place to adopt Bitcoin as the country has lived through recurrent times of economic and social crisis in recent decades.

Bitcoin Cash ABC, EOS and Ethereum Daily Tech Analysis 14/12/19 – Yahoo Finance

Posted: at 12:43 am

Bitcoin Cash ABC

Bitcoin Cash ABC rose by 1.88% on Friday. Reversing a 0.48% fall from Thursday, Bitcoin Cash ABC ended the day at $211.14.

A bearish start to the day saw Bitcoin Cash ABC fall to an early morning intraday low $205.68 before making a move.

Steering clear of the major support levels, Bitcoin Cash ABC rallied to a late afternoon intraday high $212.61.

The rally saw Bitcoin Cash ABC break through the first major resistance level at $208.12 and second major resistance level at $209.98.

At the time of writing, Bitcoin Cash ABC was up by 0.02% to $211.18. Within the first hour, Bitcoin Cash ABC rose from an early morning low $210.60 to a high $211.18.

Bitcoin Cash ABC left the major support and resistance levels untested early on.

A move back through to Fridays high $212.61 would support a run at the first major resistance level at $213.94.

Bitcoin Cash ABC would need the support of the broader market, however, to break back through to $212 levels.

Barring a broad-based crypto rally, resistance at $213 would likely pin Bitcoin Cash ABC back on the day.

In the event of a rally, the second major resistance level at $216.74 could come into play.

Failure to move back through Fridays high $212.61 could weigh on Bitcoin Cash ABC later in the day.

A fall through to sub-$210 levels would bring the first major support level at $207.01 into play before any recovery.

Barring a broad-based crypto sell-off, however, Bitcoin Cash ABC should steer clear of the second major support level at $202.88.

Major Support Level: $207.01

Major Resistance Level: $213.94

23.6% FIB Retracement Level: $269

38% FIB Retracement Level: $316

62% FIB Retracement Level: $393

EOS rallied by 1.4% on Friday. Following on from a 0.36% gain on Thursday, EOS ended the day at $2.6313.

A mixed start to the day saw EOS fall to a mid-morning intraday low $2.5803 before finding support.

Steering clear of the first major support level at $2.5364, EOS rallied to a late afternoon intraday high $2.6523.

EOS broke through the first major resistance level at $2.6392 before easing back to $2.61 levels.

Story continues

While finding late support, the first major resistance level pinned EOS back from a late breakout.

At the time of writing, EOS was up by 0.04% to $2.6323. A range-bound first hour saw EOS fall to an early morning low $2.6312 before rising to a high $2.6323.

EOS left the major support and resistance levels untested early on.

EOS would need to steer clear of sub-$2.63 levels to support a run at the first major resistance level at $2.6628.

Support from the broader market would be needed, however, for EOS to break out from Thursdays high $2.6523.

Barring a broad-based crypto rally, resistance at $2.65 levels would likely limit any upside on the day.

Failure to steer clear of sub-$2.63 levels could see EOS reverse Fridays gains.

A fall through to sub-$2.6220 levels would bring the first major support level at $2.5908 into play before any recovery.

Barring a crypto meltdown, however, EOS should steer well clear of sub-$2.58 support levels on the day.

Major Support Level: $2.5908

Major Resistance Level: $2.6628

23.6% FIB Retracement Level: $6.62

38% FIB Retracement Level: $9.76

62% FIB Retracement Level: $14.82

Ethereum ended the day flat on Friday. Following a 0.98% gain on Thursday, Ethereum ended the day at $144.70.

A bearish start to the day saw Ethereum fall to a late morning intraday low $142.76 before finding support.

Steering clear of the first major support level at $140.49, Ethereum rallied to a late afternoon intraday high $145.13.

Falling short of the major resistance levels, Ethereum fell back to $143 levels before late support kicked in.

At the time of writing, Ethereum was up by just 0.06% to $144.79. A relatively bullish start to the day saw Ethereum rise to a high $145.03 before falling to a low $144.58.

Ethereum left the major support and resistance levels untested early on.

Ethereum would need to move back through to $145 levels to support a run at the first major resistance level at $145.63.

Support from the broader market would be needed, however, for Ethereum to break out from Thursdays high $145.13.

In the event of a broad-based crypto rally, the second major resistance level at $146.57 could come into play.

Failure to move back through to $145 levels could see Ethereum hit reverse.

A fall back through to sub-$144.20 levels would bring the first major support level at $143.26 into play.

Barring an extended sell-off, however, Ethereum should steer well clear of the second major support level at $141.83.

Major Support Level: $143.26

Major Resistance Level: $145.63

23.6% FIB Retracement Level: $257

38.2% FIB Retracement Level: $367

62% FIB Retracement Level: $543

Bitcoin Weekly Forecast: Let the Santa rally begin – FXStreet

Posted: at 12:43 am

The cryptocurrency market has been painfully slow this week. With some notable exceptions like Tezos, Chainlink, and Matic, Bitcoin (BTC) and major altcoins were oscillating in tight ranges with a bearish bias. The recovery attempted at the beginning of the week failed on approach to local resistance levels, which was interpreted by some cryptocurrency experts as evidence of bulls' weakness.

The total capitalization of all digital assets in circulation has hardly changed in the recent seven days, while Bitcoin's market share decreased from 66.9% to 66.6% due to the strong growth of the simple of the above-mentioned altcoins.

The United States and Europe are anxious to get their share of the industry until it is too late. Thus, the New York state regulator proposes a new framework for coins and tokens listings. Under the proposed regulation, the companies that once received the regulatory approval for coins issuance will be able to introduce new coins without asking for additional permissions.

At this stage, the New York State Department of Financial Services (NYDFS) is gathering public comments about the plan based on a review of the existing virtual currency framework.

Europe is all about stablecoins. According to the new head of the European Central Bank, the Union needs to stay ahead of the curve. Speaking at her first ECB press-conference that followed the monetary policy decision, Lagarde suggested that the regulator should define the goals of the potential stablecoins project before moving forward.

"Are we trying to reduce costs? Are we trying to cut out the middleman? Are we trying have inclusive finance at no cost? There is a whole range of objectives that can be pursued."

She also noted that other global regulators, including the bank of Canada and Bank of England, are moving forward with their stablecoins projects, which means that there is a demand for such products that need to be addressed.

Russia and China are on the other side of the spectrum. A social media platform Weibo, also known as the Chinese Twitter, blocked the accounts of TRON's founder Justin Sun and Binance. This is just another evidence of the aggressive Chinese approach towards cryptocurrency-related business.

Meanwhile, in Russia, the Federal Service of Financial Monitoring (Rosfinmonitoring) said that it was dangerous to allow cryptocurrencies in a country prone to Ponzi schemes and financial frauds. The authorities pointed out that it might be relatively easy to regulate and control the new type of asset in small countries with a high level of law compliance; however, in Russia, it may lead to a storm of financial fraud.

The market is moving towards the Christmas season. This period is usually characterized by low trading activity and virtually non-existent liquidity, as many traders take days off.

Traditionally, it is a very boring time in terms of market movements; however, traders should stay on the alert as low liquidity may easily result in unpredictable, exaggerated moves in both directions and sudden bouts of volatility.

In December 2017 and December 2018, Bitcoin demonstrated a significant recovery ahead of Christmas. This year-end growth is known as Santa's rally, and it is typical to all financial markets. According to MarketWatch, no other month has posted a higher average return than December.

However, there is no guarantee that history will repeat. Sometimes Santa considers that traders misbehaved during the year and leave them without the long-awaited rally.

On the weekly chart, Bitcoin (BTC) is moving within the long-term downside trend with the trendline resistance currently at $9,100. This barrier is followed by SMA200 (Simple Moving Average) daily at $9,300, and 38.2% Fibo retracement at $9,000. Is this area is cleared, Bitcoin will be out of the woods. A sustainable move above this resistance zone will improve the long-term technical conditions significantly and open up the way towards 2019 high at $13,862.

Notably, three doji candles after a strong decline resemble the formation created at the beginning of October. If this time, the price will follow the same pattern, we may see a strong recovery in the area of the trendline resistance in the pre-Christmas week.

While the weekly RSI (Relative Strength Index) remains flat, the daily indicator is starting to reverse to the upside, which may signal that the recovery is underway.

On the downside, if BTC/USD moves below $7,000, the sell-off may be extended towards the support of $6,550 created by a combination of the lower line of the weekly Bollinger Band and the lowest level of the previous week. The next important barrier is seen on approach to psychological $6,000. Most likely, it will slow down the sell-off and trigger the recovery to $7,000.

The Forecast Poll of experts has improved slightly since the previous week. The expectations on all timeframes show a mixed picture as the weekly chart stayed bearish, monthly forecast turned from bearish to neutral and a quarterly timeframe is now bullish. The average price on shorter timeframes stays close to $7,000, while the quarterly target exceeded8,000, which means that analysts are more optimistic about Bitcoin's long-term fate.

Bitcoin SVs situation in the German-speaking countries – CoinGeek

Posted: at 12:43 am

The crypto sphere is international, however differences in media coverage of certain blockchain projects can be observed from country to country. In the German-speaking countries Germany, Austria and Switzerland, Bitcoin SV (BSV) seems to be underrepresented in the crypto news. One could even argue there is quite a negative connotation in almost all German reporting about Bitcoin SV so far. Why would that be the case though? Time to ask someone knowledgeable.

CoinGeeks Michael Wehrmann had the chance to win Christoph Bergmann for an interview. Christoph Bergmann is a known German Bitcoin blogger who runs bitcoinblog.de since 2013 and recently published his book Bitcoin Die verrckte Geschichte vom Aufstieg eines neuen Geldes (title translated: Bitcoin a crazy story of the rise of new money). Furthermore, he is involved in the creation of the wordpress plugin Mediopay, which uses Bitcoin SV as an easy to implement payment solution for online content.

Michael Wehrmann: Hello Christoph! Kindly give our audience your opinion on Bitcoin SV in general and tell us about your promising project Mediopay.

Christoph Bergmann: Its very simple. BTC was not allowed to grow onchain. Then BCH started to fall in love with centralized capacity planning too. So Bitcoin SV is the only Bitcoin version left which allows massive onchain scaling. This was the design outlined by Satoshi and I want to know how it plays out.

MedioPay builds on this. The idea is to use micropayments to monetize all kind of user interactions on media sites: reading, commenting, sharing, liking and so on. Its not just a paywall. Paywalls are simple and boring. If you have a bit of imagination, you can do so much more to allow journalism to make money in the Internet.

Michael Wehrmann: How would you describe the perception of Bitcoin SV in the crypto communities of Germany, Austria and Switzerland?

Christoph Bergmann: Oh, its bad. Some are interested, and if you show people what BSV can do, they open up a bit. But its a hard road, and there is always somebody reminding everyone how bad Craig Wright is and that BSV is a scam.

Michael Wehrmann: Did this perception change in the last months?

Christoph Bergmann: Not really. For most people crypto is like soccer: Once you support a team, you support it forever. Changing peoples opinion is often close to impossible.

Michael Wehrmann: You keep your audience informed about Bitcoin SV on your blog. How did your readers react to your articles concerning Bitcoin SV so far?

Christoph Bergmann: Usually not that bad. Many are open and somehow know that BSV is that thing they wanted Bitcoin to become, before it was reengineered. But many just dont care for most crypto is just an investment.

Michael Wehrmann: If you were to write more often about Bitcoin SV on your blog, how do you think your readers would respond?

Christoph Bergmann: My readers expect me to cover topics they are interested in and which are relevant for the broader crypto market. Many are customers of the platform Bitcoin.de, where Bitcoin SV has a tiny trading volume. So it would be not a good representation of the market if I wrote too often about BSV.

Michael Wehrmann: How would you describe the crypto media coverage of Bitcoin SV in the German-speaking areas?

Christoph Bergmann: Maybe as non existent. Mainstream journalists dont even know about Bitcoin SV maybe about Craig Wright, but rather in a negative way and if they try to learn, they become confused about all of this.

The largest German crypto magazine, BTC-Echo, made some fair reports, but didnt go deep, while they also had published some heavy anti BSV stories. Other blogs and podcasts are usually very anti BSV or ignore it.

Michael Wehrmann: Would you agree there is a lack of media coverage concerning Bitcoin SVs technical and economical developments in the crypto media outlets of German-speaking countries?

Christoph Bergmann: Yes, definitely. They miss a lot of thrilling things.

For example, PayMail is the most user-friendly way to use cryptocurrencies with a nice level of privacy. It is lightyears ahead of everything else. I dont know how I lived without. But you dont find any article about it outside my blog.

Also, MoneyButton is such a great tool for all kind of payments. People waste so much time not using it. Its like they decide to slow down their internet connection. But again, you dont find anything about it.

I could go on and on. We have all those scaling records, proving all those blockchain cant scale buttcoiners wrong. But again, nobody reports.

Or take TonicPOWs P2P advertising: this is a perfect example of how to decentralize a terribly centralized market. Or Unwriter and MonkeyLord literally breaking the great Firewall. Everybody in crypto wants this. And FloatSV and Okex accepting zero conf BSV deposits.

But, again and again and again: No one writes about it, no one tries it.

Michael Wehrmann: Why is that the case though?

Christoph Bergmann: Its complicated. On one side, journalists have to be selective, as attention is a limited resource, and so they focus on coins which receive more attention by readers. This is not just a problem for BSV, but also for Bitcoin Cash, Monero and Dash.

On the other side, most of us crypto journalists are part of the community. We are basically not journalists, but cheap marketers for coin holders. We are sucked in those narratives, and for most, they are highly anti BSV. So they dont WANT to write about it.

Michael Wehrmann: You attend regularly Bitcoin Stammtische (translated: Bitcoin meetups) in Germany. Describe the perception of Bitcoin SV in those meetups for us. Is there anything different you notice in comparison to how the German-speaking crypto media covers Bitcoin SV?

Christoph Bergmann: Unfortunately, no. This must be a disappointing interview for you. Ive only met one single BSV fan on a South German meetup. Even people who highly respect my knowledge and want me to give talks dont want to even try BSV. But I dont give up to change this.

Michael Wehrmann: There is a new German newsletter about Bitcoin SVs Metanet called Metanet Weekly. Tell us about that. Who is behind it and how do readers respond so far?

Christoph Bergmann: Its a project of B2029, which is a Berlin based association for Bitcoin SV. It was founded by Stefan, Ekhard and me, after we organized the first Hello Metanet workshop. With Metanet Weekly we write about all the weekly news about BSV in German. I have very little reader feedback, but our visits and email-subscriptions are on the rise.

Michael Wehrmann: The German crypto market place bitcoin.de listed Bitcoin SV as soon as possible, whereas the Austrian exchange Bitpanda did not and still does not offer Bitcoin SV to this very day. Bitpanda enables way smaller projects than Bitcoin SV to be bought and sold though and made BCH tradable pretty fast. What are your thoughts on that?

Christoph Bergmann: Exchanges and Bitcoin SV is a difficult topic. Many in BSV dont realize how big the problems are. When exchanges list or delist coins they think about profits.

The BSV community has the very noble approach to not care about trading and gambling, but focus on building. I like this, but it has the effect that trading volume on exchanges is very low. After the delisting from Kraken and Binance I expected volume on Bitcoin.de to grow. But the opposite happened. All the arbitrage tradings bots relied on Kraken and Binance API, so they broke for BSV. This made price finding unreliable.

At the same time BSV scales the nodes. This increases the costs for exchanges. Some think they will create some kind of SPV. In reality exchanges will not invest many developer hours in a coin which produces a very low volume. They will just delist.

Michael Wehrmann: In your book you present a whole chapter called civil war of Bitcoin. Tell us how you personally experienced the BTC-BCH-BSV forks and give us an idea of how the German-speaking crypto community thinks about these events.

Christoph Bergmann: Oh, I had to write this. It was a very personal story.

I never got over it that the community was so much ok with large parts of it became censored. What did Bitcoin stand against if not censorship?

Let me tell you the secret fundamental law of crypto: You always get what you dont want to get. BTC wanted censorship resistent money, and they got censorship. They wanted decentralization so much, but they got a lightning system which hardly works without middlemen for non expert users. And Bitcoin Cash wanted anarcho capitalism, but ended with centralized production quotas.

It was also disturbing for me to learn how trolling can influence and fabricate opinion. This made me really pessimistic about the future of our society. A couple of keyboard warriors with some VPN switches and a good spin doctor can mass influence people much better than all media together.

The blocksize war itself is a very complicated story. Its technically too complex for most people, and if you finally understand the technology, you realize that it has never been a question of technology at all, but of politics.

But it is complicated, and I am impressed how good BTC exercised the digital gold narrative and how they have spun up Lightning.

Michael Wehrmann: Would you say there is a German-speaking Bitcoin SV community growing at the moment? If so, where and how exactly?

Christoph Bergmann: Not much, unfortunately.

Michael Wehrmann: In March 2019 you published an article with the title Bitcoin SVs Metanet: ingenious or just insane? Is there an answer yet?

Christoph Bergmann: Mh, hard question. We still dont really know what to do with the Metanet. There are many discussions, some only want to store metadata onchain, others want to put everything onchain and cry for even lower fees.

I think real data ownership can become a big issue. If you have your data encrypted onchain, it is always available for you, like its on your own disc, but you can access it from everywhere, and nobody can steal or destroy it. If you look at what all those big scary servers do, and how they get more and more influence over the lifes of people, we really need this. In some way the Metanet is our only chance to prevent the upcoming data tyranny.

But will people realize it? Will they get out of their beloved nanny zone under the hood of a scary server? Taking care of your own data is terrifying for most.

There are many other aspects. Take all the ransomware attacks. There have been large scale attack waves, disabling the systems of cities, public services, hospitals and many large companies. Its hard to fight it with conventional methods, and its reaching a state of permanent cyber terrorism. Data on the Metanet would be immune to it, while not being as hard to access as data on a cold backup.

Or take archives. Im a historian and spent a lot of time in archives, looking through 17th century papers. Many archivars are concerned that we will have a digital dark age, because electronic data is much less durable than paper sheets. The Metanet could be a solution for this, by making data durable and selecting data economically. WeatherSV does an awesome job here, also Twetch.

So, there are many interesting ideas. When I wrote the article I suspected it was madness technically to put all the data onchain. In this regard I have become less pessimistic. But Im still sceptical if people will use it, and if they will realize that BSV is the solution and not some other data chain or non incentivized networks like IPFS.

Michael Wehrmann: Thanks for your insights!

The situation for Bitcoin SV in the German-speaking countries does not seem to be bright at this moment. However, results will speak for themselves in the long run and will sooner or later be noticed, as well as covered by all crypto media outlets. We thank Christoph Bergmann for the interview and highly appreciate his efforts to spread information about Bitcoin SVs developments in the German-speaking areas.

Billionaire Mark Cuban Says Bitcoin May Have One Valuable Use Case But Its Not As a Currency – The Daily Hodl

Posted: at 12:43 am

Billionaire Mark Cuban, a prolific investor and owner of the NBAs Dallas Mavericks, says Bitcoin will never function as a reliable currency or medium of exchange.

Says Cuban,

[Theres] no chance [Bitcoin becomes a widely-used currency]. Not because it cant work technically, although there are challenges. It could. But rather because its too difficult to use, too easy to hack, way too easy to lose, too hard to understand, too hard to assess a value.

While hackers have stolen millions in Bitcoin from centralized exchanges, Bitcoin itself, which is based on blockchain technology, has proven itself to be resilient and secure.

Cuban says there are also too many competing crypto assets, and he thinks its too much work for people to know why BTC over everything else.

Despite the critique, Cuban thinks BTC could be considered a valuable collectible similar to gold.

If you consider art or gold a viable stable financial asset, then yes. [Bitcoin] can be.

The Shark Tank star also says that Bitcoin was a bubble during the historic crypto market bull run of 2017.

He compares the flagship cryptocurrency to speculative items such as baseball collectibles and says he prefers bananas over Bitcoin because he can eat them which gives them more utility.

Bitcoin bull Anthony Pompliano, the co-founder of Morgan Creek Digital, thinks Cuban could use some more information about the worlds leading cryptocurrency, and extended an invitation to the entrepreneur via Twitter.

Hey @mcuban, I read your recent comments on Bitcoin and think you may be missing some key information. Ill fly to Dallas and we can record a podcast episode to discuss why Bitcoin is likely to be the next global reserve currency. You in??

On the quantum dance floor, the ‘twist’ is king – William & Mary News

Posted: at 12:42 am

In 1986, two relatively unknown physicists, working in a laboratory on a Swiss hilltop, made a discovery that started a revolution.

It was the Woodstock of condensed matter physics, said Enrico Rossi, associate professor of physics at William & Mary. People were so excited. It changed everything.

Physicists J. Georg Bednorz and K. Alex Mueller discovered superconductivity in ceramic material, specifically lanthanum-based cuprate perovskite, and created the first high-temperature superconductor.

The discovery earned them the 1987 Nobel Prize in Physics and held the promise that one day it could be feasible to transmit electricity and information over vast distances with virtually no loss of current or data.

They were basically playing with this ceramic material and found that it became a superconductor at temperatures well above absolute zero, well above the limit that theory predicted was possible, Rossi said.

The typical flow of electric current, the kind that powers the average household, is a charge carried by electrons that move through a circuit made from copper wiring. The electrons move from one atom to another as they travel through the wiring, which creates a current that provides power to the home.

With copper, and almost any other material, there is a certain level of resistance against the moving electrons, sort of like air resistance pushes back on a thrown tennis ball. The less resistance, the better the electrons can move and the current will flow more freely. Superconductivity is a phenomenon in which the resistance against an electric current flowing through a material is zero.

The problem with superconductivity is that it happens at very low temperatures, close to 0 Kelvin or -459.67 degrees Fahrenheit. The idea of room-temperature superconductivity is something like the El Dorado of materials science, Rossi explained.

Such a discovery would pave the way for ultrafast computers, far more efficient power transmission and high-speed trains that could travel hundreds of miles per hour with little power. For now, the City of Gold remains elusive. Bednorz and Mueller earned their Nobel for reaching superconductivity at 35 Kelvin, or -396.67 degrees Fahrenheit.

There was the hope that we could go all the way up to room temperature, Rossi said. That would be a true revolution, because you could have no dissipation in everyday connections. But were stuck in lower temperatures and, from an academic perspective, we still dont understand why these ceramic materials are superconducting.

Rossi says part of the difficulty may be that ceramic materials have a complicated chemical structure that makes it challenging to identify the key ingredients that lead electrons to superconduct. He and Xiang Hu, a postdoc research assistant in the universitys Department of Physics, are co-authors on a paper recently published in Physical Review Letters, the American Physical Societys flagship publication.

The duo collaborated with researchers from Microsoft Quantum and the Polish Academy of Sciences to examine what leads electrons to superconduct in twisted bilayer graphene. Their work was supported by an NSF-CAREER grant, the Office of Naval Research, the Army Research Office and the United States-Israel Binational Science Foundation.

Twisted bilayer graphene is a material made from taking a one-atom-thick layer of carbon atoms and folding it over on itself at a slight angle, 1.05 degrees. By folding it at that precise angle (what physicists call the magic angle), the atoms line up in such a way that the material becomes a superconductor.

The fundamental mechanism that leads to superconductivity might be the same as in the ceramic materials, but the chemical structure of twisted bilayer graphene is much simpler, Rossi explained. The revelation started a new field called "twistronics" and opened the door for researchers like Rossi and Hu to study the underlying physics of superconductivity.

Its really about the way the system is engineered, Rossi said. Take, for example, something like chalk. You can break a brick of chalk really easily, but that same material makes shells, which can last for centuries. It has to do with the nature of how the atoms are arranged. That same principle applies for creating superconductivity in graphene.

Rossi and the team of researchers found that the specific arrangement of atoms, and the way such arrangement affects the quantum state of each electron, can explain why electrons in graphene superconduct.

It helps to think of the phenomenon as a kind of quantum square-dance, with the folded matrix on which the atoms are arranged as the dance floor. The dancers are electrons, who, as the evening goes on, couple up with other electrons in groupings called Cooper pairs, a key element of superconductivity.

In twisted bilayer graphene, the electrons are forced to move slowly. If you slow them down, make the velocity very small, and you allow the electrons to spend more time in the same place, they start interacting and pairing up, Rossi said. Naively, you would also expect that to lead to pure superconductivity, because the electrons have enough time to form pairs and form a lot of them. However, if these Cooper pairs are all by themselves, doing their own thing, then the system is not going to superconduct and conventional results suggest that this would be the case in twisted bilayer graphene.

In simpler terms, to achieve superconductivity, the quantum square-dance must become a giant conga line with all the Cooper pairs joining together. If couples keep to themselves, the material doesnt superconduct. Rossi, Hu and their collaborators discovered how this happens in twisted bilayer graphene, despite the extremely small velocity of the electrons.

The way I like to explain it is that somehow they all need to link arms, Rossi said. Imagine there is a chain of people and theyre all going forward, but then they hit an obstacle. If the pairs arent linked together, then one pair will stop when they hit the obstacle and the other may keep going.

If only half the pairs are getting around the obstacle, Rossi explained, then the amount of current the system can carry is cut in half, causing electrical resistance. Half of the pairs are getting stuck. If all the electrons are able to link together, then they can pull each other past obstacles and the electrical resistance shrinks to zero.

The strength of this linkage is really important, Hu said. Using previous results, one would conclude that such strength would be vanishingly small in twisted bilayer graphene. The fact that it's possible for the linkage to be present in twisted bilayer graphene has not been examined before now.

Once the researchers realized that the conga line formation in twisted bilayer graphene was crucial for superconductivity, they set out to figure out why it happens. Instead of looking at the dancers, the team looked at how they dance.

They found it was actually the individual nature of each couple (the electron pairs individual attributes, analogous to spin) that had the greatest impact on linkage. It had a greater impact than their size or speed or how much time they spent on the quantum dance floor.

At first, the focus was on the velocity. When it goes to zero, you can form couples and thats great, but its not enough, Rossi said. You need to be able to make all those couples somehow link up. Thats what you need to get superconductivity. The assumption was that this linking was also due to the velocity, but that was neglecting the fact that there is another way. It has to do with the individual features of the quantum states. Its a contribution people hadnt considered before.

Over Regulating Intermediaries: Threat To Free Speech? – Inc42 Media

Posted: at 12:41 am

The internet has become a part of everyones lives as compared to the impact it had even a decade ago

Your Amazon reviews have the same impact as your Facebook status update

The amendments to the draft IT Intermediary Guidelines, 2018 initiated a new debate

Editors Note: This article was written before the Personal Data Protection Bill was approved by the Union Cabinet with undisclosed changes to the Draft version of the Bill which this author has based their opinions on. Therefore, some opinions expressed below may no longer be applicable under the revised Bill. You can check all the articles of this series here.

In August 2017 Justice Abhay Manohar Sapre very poignantly noted, while reading out the judgment on the Puttaswamy case that right to privacy of any individual is essentially a natural right, which inheres in every human being till he/she last. It is indeed inseparable and inalienable from human beings.

In other words, it is born with the human being and extinguishes with the human being. The right to privacy is a fundamental right that is distinctly connected with human dignity by securing their inner thoughts and expressions from any form of unwanted intrusion.

Today, the internet has become a part of everyones lives as compared to the impact it had even a decade ago. People from all backgrounds, genders and ages have an online presence. Whether it is for business purposes or personal, most conversations and communications amongst people happen online. From buying groceries to speaking to your mother at the other end of the world, everything can be achieved with a good internet connection, a usable device and an online communication platform.

Along with this increase in communication, comes a boost in public expression. The internet has made it possible for people to express their thoughts, opinions and arguments on everything in the world from avocados to the US elections to the world at large. These expressions spark debates, encourage conversations and lead to discussions amongst like-minded people, helping people feel a sense of community and camaraderie.

It is clear with the widespread use of the internet across all communities, societies and sectors that the pervasiveness of the internet is worldwide, making it a vertical form of business and not horizontal anymore. The internet and social media have become a staple part and act as the foundation of human expression in todays times.

Your Amazon reviews have the same impact as your Facebook status update i.e. they both help you communicate your personal opinions to those who you voluntarily want to convey them to. Therefore, freedom of expression is highly dependent on the freedom to express over social media. Therefore, making the internet a safe and free space is essential to uphold this fundamental right that is allowed for each human being.

The platforms mentioned above have been termed as intermediaries, which is a platform for user-generated content. They use the capabilities of the web to act as platforms where information is shared. Intermediaries are themselves not seen as publishers of content but rather serve as the place where user content is shared. The question that arises with the growth of intermediaries is the accountability that they have on the content that is shared on their platforms.

What responsibilities and protections come with hosting Indian user content and how liable are they for the content shared. The amendments to the draft IT Intermediary Guidelines, 2018 initiated a new debate on the curbing or censoring of this content equalling to the violation of the content creators freedom of speech and expression.

The proposed draft rules have gone beyond the scope of the provisions of the parent act and erodes the safe harbour protection available to intermediaries under section 79 of the IT Act. As noted in the landmark judgement of Shreya Singhal v. Union of India, the intermediary is called upon to exercise its own judgment under Rule 3 sub-rule (4) and then disable information, when intermediaries by their very definition are only persons who offer a neutral platform through which persons may interact with each other over the internet.

Thus, it then solely depends upon the intermediaries subjective sense, to take down content, which has a chilling effect on freedom of speech and expression. The requirement for intermediaries to subjectively determine the legality of an expression should be replaced with an objective test. The objective test should be such that it does not create an obligation for the intermediary to go into the adjudication of a legal claim or into the investigation of facts and circumstances.

The rules are procedurally flawed as they ignore elements of principles of natural justice and lacks safeguards. Under the rules, the third party provider of information whose expression is censored is not informed or made aware about the takedown, let alone given an opportunity to be heard before or after the takedown. There is no redressal mechanism for the aggrieved user or third party uploading or providing the content, to appeal the decision of the Government agency in the courts.

Reasoned state action must recognize that their liabilities must necessarily vary with the specific type of service that each provides. The Intermediary Guidelines fail to do so, and are consequently incompatible with Article 14. There needs to be a classification made with respect to the type of intermediaries. A singular watertight formula cannot be applied to all intermediaries. There needs to be a tactical separation between User Generated Content space and Curated Content providers. The guarantee of equal protection of laws requires equality of treatment of persons who are similarly situated, without discrimination inter se. It is a corollary that people differently situated cannot be treated alike.

Once the government recognises different types of intermediaries, a differential regulation needs to be established as well. Intermediaries can be classified into:

Distinct classes of intermediaries should be created and due diligence requirements be assigned as per the functions performed by each of intermediaries.

The guidelines mandate intermediaries to disable access to unlawful content without the requisite procedural safeguards under Rule 3(8). Moreover, the guidelines leave it on intermediaries to remove the content from their platforms proactively, which could amount to censorship. The issue with proactively trying to censor content is that its effects can spill over into censorship and impact the freedom of speech, internet is supposed to enhance and enable.

Additionally, these rules have not been understood context of Section 79 of the IT Act which is an enabling provision. It needs to be clarified that these guidelines do not create new offences but instead provide the intermediaries a safe harbour to avoid taking liability for most offences.

In order to combat this gap in the regulation and the blatant violation of human rights a balanced approach needs to be taken where when intermediary platforms are used for the transmission of allegedly obscene and objectionable contents, the intermediaries/service providers should not be absolved of responsibility. And at the same time when they take down content that does not fit into the category of offensive/obscene/threatening, they should be answerable to the creator of the content and via the due process of law provide evidence and reasoning for their actions.

It is clear that a definite obligation should be cast upon the intermediaries/service providers in view of the irreparable damages caused to the victims through reckless activities that are undertaken in the cyberspace by using the service providers platform and make them accountable for the actions they take based on their assumptions or interpretations. Casting such an obligation seems imperative, seeing as how the aggrieved party has no legal recourse or direct contact with the said platform managers.

Charter of Freedom of Speech and Academic Freedom to be adopted – News – The University of Sydney

Posted: at 12:41 am

The recommendations and revised Charter were developed in response to an independent review of freedom of speech in Australian higher education providers, commissioned by the federal government and conducted by former High Court Chief Justice the Hon Robert French AC.

A key recommendation of Mr Frenchs report was that all registered Australian higher education providers should voluntarily adopt a Model Code for the Protection of Freedom of Speech and Academic Freedom in Australian Higher Education Providers developed as part of the report.

Dr Spence welcomed the French review and established a University French Review Model Code Implementation Group to prepare recommendations on how to implement the Code most effectively to further strengthen the Universitys already robust framework promoting and protecting freedom of speech and academic freedom on its campuses and facilities.

The Implementation Groups report and recommendations were released to the University community in October. They have since been endorsed by the executive and key governance committees, including the Academic Board last month with just minor amendments, and by the Senate yesterday afternoon.

Dr Spence explained that one of the amendments made by the Academic Board was to include the word courage in the Charter.

This change recognises that as an institution and a community we greatly value courage, civility and respect and seek to promote a climate where people disagree well, Dr Spence said.

The term disagreeing well was also added to the 2008 Charter on recommendation of the Implementation Group.

Is YouTube Cracking Down on Free Speech With New ‘Harassment Policy’? – NewsBusters

Posted: at 12:41 am

The video sharing platform and sister organization to Google may be cracking down on free speech -- this time under the guise of protecting users from harassment. YouTubes Vice President and Global Head of Trust & Safety Matt Halprin released a blog on Wednesday, Dec. 11, titled An update to our harassment policy.

As of today, YouTubes blog announced a series of policy and product changes that update how we tackle harassment on YouTube from both creators and commenters. Free speech advocates may be rightly concerned with slippery terms such as malicious insults, veiled threats via simulated violence and, of course, hate speech.

Harassment hurts our community by making people less inclined to share their opinions and engage with each other. Haplrin wrote. We heard this time and again from creators, including those who met with us during the development of this policy update. Halprin said that his company met with a wide range of advisors from various political backgrounds, from organizations that study online bullying or advocate on behalf of journalists, to free speech proponents and policy organizations from all sides of the political spectrum. YouTube reiterated this message in a tweet, stating, we consulted with a wide array of creators, experts and organizations to update our harassment policy.

Halprin tried to assure those concerned with free speech that they have nothing to fear in stating, We remain committed to our openness as a platform and to ensuring that spirited debate and a vigorous exchange of ideas continue to thrive here. But Halprin asserted that YouTube will not tolerate harassment.

Weve always removed videos that explicitly threaten someone, reveal confidential personal information, or encourage people to harass someone else, Halprin claimed. But in the future, our policies will go a step further and not only prohibit explicit threats, but also veiled or implied threats.

Such threats were described as including content that simulates violence or language that suggests physical violence might actually occur. No individual should be subject to harassment that suggests violence, wrote Halprin.

When it comes to hate speech, YouTube proclaimed that it will no longer allow content that maliciously insults someone based on protected attributes such as their race, gender expression, or sexual orientation. This applies to everyone, from private individuals, to YouTube creators, to public officials.

YouTube wrote that sometimes harassment can also take the shape of a pattern of behavior across multiple videos, suggesting that such repeated behavior could run afoul their new harassment policy even if any individual video doesnt cross our policy line.

In response, YouTube will be tightening our policies for the YouTube Partner Program (YPP) to get even tougher on those who engage in harassing behavior and to ensure we reward only trusted creators. Channels that repeatedly brush up against our harassment policy will be suspended from YPP, eliminating their ability to make money on YouTube.

In addition, Halprin wrote, We may also remove content from channels if they repeatedly harass someone. If this behavior continues, well take more severe action including issuing strikes or terminating a channel altogether.

Halprin then pivoted to discuss commenters who leave notes in the comment section beneath videos.

We know that the comment section is an important place for fans to engage with creators and each other, Halprin suggested. At the same time, we heard feedback that comments are often where creators and viewers encounter harassment. This sort of toxic commentary, continued Halprin, not only impacts the person targeted by the harassment, but can also have a chilling effect on the entire conversation.

To those concerned with freedom of speech, YouTube attempted to reassure readers that not just any negative commentary would be censored. Weve continued to fine tune our systems to make sure we catch truly toxic comments, Halprin suggested, not just anything thats negative or critical, and feedback from creators has been positive.

The blog also touted YouTubes recent changes with regard to borderline content and authoritative sources, breaking from its open video platform montra. Halprin noted that the platform is reducing the spread of borderline content [and] raising up authoritative voices when people are looking for breaking news and information and rewarding trusted creators and artists that make YouTube a special place. He also noted that the platform is committed to continue revisiting our policies regularly to ensure that they are preserving the magic of YouTube, while also living up to the expectations of our community.
