Italy: Blockchain Technology Helps Develop Smart City Project

Blockchain technology is among the six major technologies in Italy that will improve the quality of life in the city. The technology is clean, secure and on-demand mobility. 2019 is just one month old and most people consider it as the turning point for the induction of tech and unfeigned nationals’ plans for the switching of urban centres to smart cities.

A comparison was made sometime back between those who dwell in the city. The challenge isn’t in the high use of technological solutions, but rather at the low level of involvement, joint operation, and the inclusion of Italian citizens in the integral strategic choices made for the digital transformation of the City Centre.

The implementation of the blockchain will enable firms to save around $50 billion annually at first, and over $500 billion annually after blockchain technology networks reach the mass market.

However, efficiency isn’t the key feature of this technology. It enables users to make the entire system less dependent on legion intermediaries and greatly ameliorate its transparency.

Human Fabric

The human framework of a city is largely characterized by cultural, economic, social and other specifics. Integrating crypto and blockchain technology into a development plan could represent an efficacious choice of each stakeholder, from the angle of massive cooperation among citizens and communities, focusing on having a marvelous future for all people.

Technological innovation such as Blockchain is an enormous resource for those who dwell in the city, since it enables them to work on a wide range of critical factors, beginning with quality of life and going on to several direct opportunities for citizens and firms.

Technological Epoch

The Internet of Things (IoT), big data, autonomous vehicles, security and distributed ledger technology (DLT) are some of the chief technologies of the digital transformation. In order to work well, a network that is much faster than the present one is necessary.

DLT, one of the most promising technologies to address issues of security and personal information. Billing, financial transactions, contracts of all sorts, service management, will be the primary field of application.

Meanwhile, Italy is planning to turn Ticino, Switzerland into a ‘Cryptovalley’ in order to boost community growth, as Coinidol reported. Particularly blockchain, online and smart contacts system collection protocol that is earmarking large space most especially in the epoch of financial transactions & exchanges of digital currencies.

Blockchain Browser Brave to Offer Free Access to Premium Cheddar Content

Blockchain-based internet browser Brave has partnered with news website Cheddar to offer free access to its premium content for a limited period.

The firms jointly announced Tuesday that Brave browser users will be able to automatically unlock premium content on Cheddar website for the next three months starting today.

“Cheddar viewers are obsessed with crypto; we even have a show dedicated to it – The Crypto Craze. The idea of unlocking our premium feeds for Brave users via crypto funding, with no sign-up, seemed like a natural way to engage a passionate community,” said Jon Steinberg, Cheddar’s founder and CEO.

Brave, founded in 2015 by Mozilla co-founder Brendan Eich, raised about $35 million under 30 seconds through a sale of its ethereum-based basic attention token (BAT) back in May 2017.

Since then, the privacy-focused browser, which claims to have 5.5 million monthly active users currently, has been looking to offer new services. Last April, it partnered with Dow Jones Media Group to experiment with a blockchain content delivery system.

Most recently, Brave said that it will begin using blockchain identity startup Civic’s verification services to ensure publishers are paid for their content with its token.

BAT was also recently added by crypto exchange Coinbase to its retail and professional trading platforms.

Scientists Create Liquid Fuel That Can Store The Sun’s Energy For Up to 18 Years

No matter how abundant or renewable, solar power has a thorn in its side. There is still no cheap and efficient long-term storage for the energy that it generates.

The solar industry has been snagged on this branch for a while, but in the past year alone, a series of four papers has ushered in an intriguing new solution.

Scientists in Sweden have developed a specialised fluid, called a solar thermal fuel, that can store energy from the sun for well over a decade.

“A solar thermal fuel is like a rechargeable battery, but instead of electricity, you put sunlight in and get heat out, triggered on demand,” Jeffrey Grossman, an engineer works with these materials at MIT explained to NBC News.

The fluid is actually a molecule in liquid form that scientists from Chalmers University of Technology, Sweden have been working on improving for over a year.

This molecule is composed of carbon, hydrogen and nitrogen, and when it is hit by sunlight, it does something unusual: the bonds between its atoms are rearranged and it turns into an energised new version of itself, called an isomer.

Like prey caught in a trap, energy from the sun is thus captured between the isomer’s strong chemical bonds, and it stays there even when the molecule cools down to room temperature.

When the energy is needed – say at nighttime, or during winter – the fluid is simply drawn through a catalyst that returns the molecule to its original form, releasing energy in the form of heat.

“The energy in this isomer can now be stored for up to 18 years,” says one of the team, nanomaterials scientist Kasper Moth-Poulsen from Chalmers University.

“And when we come to extract the energy and use it, we get a warmth increase which is greater than we dared hope for.”

A prototype of the energy system, placed on the roof of a university building, has put the new fluid to the test, and according to the researchers, the results have caught the attention of numerous investors.

The renewable, emissions-free energy device is made up of a concave reflector with a pipe in the centre, which tracks the Sun like a sort-of satellite dish.

The system works in a circular manner. Pumping through transparent tubes, the fluid is heated up by the sunlight, turning the molecule norbornadiene into its heat-trapping isomer, quadricyclane. The fluid is then stored at room temperature with minimal energy loss.

When the energy is needed, the fluid is filtered through a special catalyst that converts the molecules back to their original form, warming the liquid by 63 degrees Celsius (113 degrees Fahrenheit).

The hope is that this warmth can be used for domestic heating systems, powering a building’s water heater, dishwasher, clothes dryer and much more, before heading back to the roof once again.

The researchers have put the fluid through this cycle more than 125 times, picking up heat and dropping it off without significant damage to the molecule.

“We have made many crucial advances recently, and today we have an emissions-free energy system which works all year around,” says Moth-Poulsen.

After a series of rapid developments, the researchers claim their fluid can now hold 250 watt-hours of energy per kilogram, which is double the the energy capacity of Tesla’s Powerwall batteries, according to the NBC.

But there’s still plenty of room for improvement. With the right manipulations, the researchers think they can get even more heat out of this system, at least 110 degrees Celsius (230 degrees Fahrenheit) more.

“There is a lot left to do. We have just got the system to work. Now we need to ensure everything is optimally designed,” says Moth-Poulsen.

If all goes as planned, Moth-Poulsen thinks the technology could be available for commercial use within 10 years.

The most recent study in the series has been published in Energy & Environmental Science.

Bloq Labs Reveals Software Suite That Aims to Increase Hash Power by Double Digits

The blockchain organization Bloq Labs has introduced a beta version of a new software suite for cryptocurrency miners called Titan. Bloq co-founder Jeff Garzik announced the project at the recent Binance conference in Singapore and claims the protocol can maximize a mining machine’s hashrate by double digits with thoughtful configuration and dynamic adjustment.

Titan’s Mining Management Software Suite Claims to Increase Hash Power by Double Digits

Back in the spring of 2017, the company Bloq introduced a new part of the business called Bloq Labs that aims to support open source projects in the bitcoin and blockchain ecosystem. According to the company’s CEO, Jeff Garzik, Bloq Labs has created a waiting list for miners who want to participate in Titan’s beta testing. The Titan protocol is a software suite dedicated to overseeing cryptocurrency mining infrastructure. If configured correctly, Bloq Labs claims, Titan can increase a mining pool’s hash power “by double digits.” “Titan gets the most out of your machines,” explains the software’s website

Bloq Labs Reveals Software Suite That Aims to Increase Hash Power by Double DigitsTitan has started its waiting list for beta trials.

According to Titan CEO Ryan Condron, the project has been working in stealth mode for some time now and says the software will make “crypto mining easier, more profitable, and more scalable.” Titan has opened its beta waitlist to the public and at the time of publication, there are 71 registrants so far according to the website counter. The Titan program is free to install but the company will gain profit from advanced hashrate production.

Maximize a Mining Rig’s Shelf Life With Titan’s Efficiency

Titan can be tethered to an entire mining farm, improve watt extraction, and provide further optimizations like enhancing overclocking through a proficient system of machine learning. The team hopes large mining facilities will be attracted to Titan’s offerings. Additionally, Titan’s software will be able to mine multiple cryptocurrencies with different consensus algorithms. The protocol will maximize the devices’ shelf life and shave operation costs by keeping machines up to speed, the company’s website explains. Titan’s website also notes that less downtime in the mining industry equals more money.

Titan CTO Kyle Howlett says:

“[Titan] is a fully integrated and comprehensive software suite that not only utilizes existing tools but adds a whole new layer of automation and optimization onto any mining operation.”

“The fact is, managing mining hardware is a very manual process — Not only do you have to individually access and configure each device, but you must continually monitor and adjust your devices to make sure that they are online and mining the most profitable coin,” explained Condron during the beta launch announcement.

“Additionally, there’s the balancing act of managing operational costs and physical infrastructure concerns, such as electricity costs, wire management, and heat dissipation.”

The Titan project is also led by the creator of the cryptocurrency mining profitability website Coinwarz Kyle Howlett. The project’s CTO has been creating mining tools for better ROI since 2012 and he believes the new software takes things to the next level. If configured properly with a mining farm the Titan software brings plug-and-play capabilities to mining, emphasized Howlett. Further, the organization detailed that it has a slew of new optimization features to disclose in the coming months.

How compressed-air storage could give renewable energy a boost

Compressed-air energy storage isn’t carbon neutral, but it’s a lower-carbon option.

Decarbonizing the world’s electricity grids won’t be an easy task, but it is a necessary one if we’re going to mitigate some of the worst effects of climate change. Since wind and solar power are intermittent, part of decarbonizing the grid will involve storing renewable energy for use when the Sun isn’t shining and the wind isn’t blowing.

While day-to-day storage will cover the gaps when the wind slacks or the Sun sets, on grids with more than 80 percent renewable energy you’re also going to want inter-seasonal storage. This is because sun and wind are seasonal, and energy demand is also seasonal—people use a lot more energy in the winter than they do in the spring, because it’s darker and colder outside.

Researchers from the University of Edinburgh and the University of Strathclyde think that one potential step toward seasonal storage should involve identifying large underground saline aquifers where energy could be stored as compressed air. Saline aquifers are usually found underwater; the compressed air will displace some of the water, which can be discarded, as it’s not potable.

Massive reservoirs of compressed air could handle the inter-seasonal gaps that high-renewable grids might struggle with. The researchers suggest a system where excess renewable energy is used to compress air and pump it down into a saline aquifer over the course of several months. Then, when it’s needed in the winter, the air is brought back up and expanded, powering a turbine that drives electricity back onto the grid.

The cycle is comparable to how many regions store and use natural gas. That is, excess natural gas is pumped into underground storage caverns where it sits for a few months. In the winter, when gas is needed to heat homes, those stores are drawn down. The difference here is that the energy being stored isn’t chemical.

The researchers used existing geological mapping that was conducted around the United Kingdom to find potential storage areas for carbon dioxide (CO2), but their method for vetting geological repositories for compressed air storage could be applied to underwater geographies around the world.

They found that at least 77 to 96 terawatt-hours (TWh) of electricity could be stored in aquifers off the British coastline. (That is roughly 160 percent of the UK’s electricity consumption in January and February 2017, so combined with other forms of electricity, it would be more than enough for a typical winter.)

An imperfect solution

Despite the sound theoretical basis for developing massive underwater wells for storing compressed air, the researchers acknowledge that it’s an imperfect solution to our energy storage problems.

For one, it’s expensive. The researchers estimate that storing compressed air in saline aquifers would cost in the range of $0.42 to $4.71 per kilowatt-hour (kWh).

For comparison, Lazard’s 2018 Levelized Cost of Storage report (PDF) found that the high-end cost of lithium-ion batteries for wholesale energy storage was about $298/MWh, or about $0.30/kWh. Of course, most utility-grade lithium-ion batteries on the world’s grids today are geared toward short-duration frequency response rather than long-duration applications like compressed-air energy storage schemes. Somewhat higher-cost, long-term energy storage schemes might be viable if governments start mandating more and more renewable energy on the grid.

Another problem with this scheme is that carbon-neutral compressed-air energy storage isn’t (yet) commercially proven. When conventional compressed air systems need to expand the stored compressed air to put additional energy on the grid, they do it by warming the air up by burning fossil fuels. Very cutting-edge compressed-air systems can be carbon neutral by recycling the heat that’s removed from the air when it’s compressed, but these so-called “advanced adiabatic compressed air systems” exist only as pilot projects and small-scale trials, unlike conventional compressed air systems, which have been in use for decades.

Even if it involves heating the air with fossil fuels, compressed-air energy storage emits less carbon per kWh than running a natural gas plant (and currently many grids, especially in the US, use quick-starting natural gas plants to complement the intermittency of renewables, so exchanging that for compressed-air energy storage is an advance in the right direction). Conventional compressed-air energy storage releases approximately 228g of CO2 per kWh, which is “less than the 388 grams of CO2 per kWh reported for the combined cycle gas turbines used in gas power plants,” the paper notes.

For now, even conventional compressed air energy storage is rather rare; only two commercial compressed air facilities are currently operating: one on the grid in Germany and one in Alabama. In their paper, the researchers write that 8TWh of potential compressed air storage could be built out in the UK onshore, in salt caverns. Using these onshore caverns for compressed air would cost just a fraction of what it would cost to build compressed air storage in saline aquifers. For that reason, the researchers recommend that compressed air facilities “should be initially developed onshore to improve the technology and reduce operational costs.”

Mythical Games Join Forces with EOS to Create a Digital Goods Standard for Blockchain Developers

Mythical Games, a next-generation game technology studio, EOS Lynx, Scatter and several highly-reputed distributed ledger technology (DLT) projects are set to launch an industry-wide initiative aimed at formalizing the fast-growing digital assets marketplace via the Distributed/Digital Goods standard (dGoods standard).

The Need for a Robust Digital Goods Ecosystem

The group hopes to establish a benchmark for creating, managing, and distributing digital products between creators, studios, and consumers, according to a report from AP News on January 23, 2019.

In a bid to create a robust and formalized digital goods industry, Mythical Games, a U.S.-based video games technology platform, focused on bringing players, developers and content creators closer to the games they love. They have also reportedly allied with EOS Lynx, Scatter, and other blockchain platforms to launch the Digital Goods standard.

As stated in a press release by the team, the initiative is looking to put in place a “commercially-endorsed benchmark for creating, managing and distributing digital products such as games, coupons, music files and more.”

The team is poised to establish a robust digital goods standard for the development community by creating Metadata Templates for 3D and 2D digital assets and more. Part of the initiative involves specifying templates for metadata according to the digital good a developer is working with.

The team says standard templates will be created to correspond with each digital good so that wallets will display the relevant information, images, and 3D objects correctly.

Digital Objects Need Certificates of Authenticity

Just like in the real world where objects have certificates of authenticity, the team plans to make it possible for digital objects to have a certificate of authenticity by building immutable fields in dGoods which will describe the object’s characteristics that make up the certificate of authenticity “as well as graphical representation to show users as a proof of the object’s attributes including its brand, creator and other details.”

“Hundreds of millions of digital items will be created, bought, and sold in the years ahead. It’s critical that we establish a meaningful digital goods standard that can support a vast array of innovative development communities,” declared Rudy Koch, Head of Blockchain at Mythical Games.

dGoods to Go Live on EOSIO

The team has made it clear that with dGoods, developers will be able to choose whether tokens created will be fungible or non-fungible as the dGoods standard has the ability to define sub-tokens within one contract.

dGoods will be rolled out first on EOSIO blockchain, with other blockchains to follow in the near future. The EOS blockchain network has seen significant adoption in recent times despite the harsh words of critics against the platform.

Earlier in December 2018, BTCManager reported that Huobi had announced plans to launch its EOS-powered crypto exchange in Q1 of 2019.

Cambridge Scholars Invent Scheme to Track Stolen Bitcoin

A group of students from the UK’s prestigious Cambridge University has outlined a system whereby stolen Bitcoins might be able to be traced.

With the official number of stolen Bitcoins currently standing at over USD 1 billion in BTC, until now, such coins have remained largely untraceable. But three students, Mansoor Ahmed, Ilia Shumailor and Rose Anderson, have released their paper entitled “Tendrils of Crime“, outlining a plan for their recovery by victims of fraud.

The Cambridge paper outlines a system called Taintchain using a device called “first-in-first-out” (FIFO), a method which has been identified to have ancient origins in terms of accounting, and more recently within the legal system.

FIFO apparently calculates each Bitcoin’s satoshi, the principal units — a Bitcoin comprising 100 million satoshis — which are loaded with the required information to create transactions. FIFO, according to the Cambridge group, can track the movement of these transactions back to the Genesis wallet. “First in first out” simply means that if the first coins into the wallet were stolen, then so must be the first coins paid out from the same wallet.

It does appear to ignore that advanced features in some wallets such as “coin control” or input control mean that users can determine which inputs, expressed as coins, are used in a transaction.

The group has expressed confidence in the FIFO methodology as a way of tracking stolen Bitcoins suggesting, that despite a few basic issues still to be dealt with, the approach will work, given more innovation and further research.

Vechain (VET) Developing Something New, CEO Says Blockchain Alone Not Enough

While blockchain technology seems to be the salvager of some of the long time glitches in the technology industry, people have begun sighting some of the lapses of the new era modernism for corrections to be made in subsequent innovations.

Similarly, the CEO of the Vechain (VET) blockchain foundation, Sunny Lu, at an Ask Me Anything (AMA) forum organized by Token Gazer, related that blockchain technology alone is not sufficient in the space.

Sunny Lu said for blockchain to be effective as an enterprise solution, it needs to be linked with a number of technologies.

While at the AMA session organized by the digital currency media group in Shanghai, Lu noted that Vechain (VET), in collaboration with DNV GL and their Business Assurance Service, is innovating something new and outstanding in the blockchain space.

Vechain is a step ahead of others, it is developing a real-time 24/7 available global technical support service for enterprises, the CEO explained, adding that having multiple layers of BaaS support with small and medium enterprises ‘portal-based’ solutions would really go a long way in thriving businesses around the world.

Vechain (VET) Maintaining Balance Total Decentralization And Centralization

Another major topic which flooded the AMA session was governance. There, Sunny Lu nailed the importance on staying between total decentralization and centralization.

After proper observation of the blockchain technology, VeResearch Universities came up with such governance system as being most effective for the technology. He deliberated that it is a Western-style approach to governance. A governance which heightens stake for fraud to a level that makes its completely unreasonable rather than prohibition the possibility of fraud altogether.

He also highlighted the thin line between private chains and public chains with the assertion of Dan Boneh from Stanford University. He said Boneh likened private chains to LAN and matched open web with public chains.

In the CEO’s entire message, it was clear that Vechain (VET) is an avid supporter of enterprise applications, and the blockchain foundation seems to have a clear business acumen over other projects that are being affected by impediments.

Is There a Future for Cryptocurrencies in the Online Casinos?

Anyone who has not been living under a rock for the past couple of years has surely heard other people speaking about blockchains and cryptocurrencies. Not surprising, considering they have completely revolutionized the way we process payments over the internet.

The blockchain technology has made its way into a variety of sectors including the online gambling industry. Some of the leading providers of interactive gambling content have already embraced this new form of currency and enable payments via Bitcoin, Ethereum, and Litecoin. The past couple of years also saw the launch of various online casinos that rely exclusively on cryptocurrencies for their payments. 

How the Blockchain Technology Affects Online Casino Players?

This is no coincidence and here is why. First and foremost, cryptocurrencies have become the epitome of safety. Online gambling operators do take all the necessary precautions to ensure their customers’ information is kept out of harm’s way. Unfortunately, hackers have also upped their skill levels so there is no guarantee players’ sensitive data is completely out of their reach.

This is not the case with blockchains which rely on cryptography to safeguard the data. The technology needs no third parties to act as intermediaries and is decentralized. It is not associated with a particular jurisdiction or financial institution.

Thus, cryptocurrency-based online casinos enable gamblers to retain their full anonymity. This is not the case at traditional betting sites where customers are normally required to send some personal documents for the verification of their accounts.

This not only results in inconvenience for the customers but may also hurt the casinos’ business since most players are just itching to jump right into the betting action. The blockchain technology poses as a solution to this problem since it can greatly simplify the sign-up process or even altogether eliminate it. Some crypto-based casinos have completely done away with registration and allow their new customers to start wagering immediately after they send a Bitcoin to the specified address.

As mentioned on SuperCasinoSites, cryptocurrencies enable faster, easier deposits and withdrawals, eliminating the necessity of providing your personal information in the first place. The only things you need to make a cryptocurrency payment are your name and the details of your crypto wallet. The financial transaction takes place with the help of both public and private keys, which further consolidates security.

Since the blockchain technology is not controlled by any financial institution, payments conducted in this manner are either incredibly cheap or entirely void of additional costs. The same cannot be said about some of the widespread conventional methods of payment, which often involve hefty service fees. Additionally, cryptocurrencies allow for larger sums to be deposited or withdrawn from online casinos.

Since no country’s government controls the blockchains, cryptocurrencies pose as the perfect solution for casino fans from jurisdictions with more restrictive legal and regulatory frameworks on online gambling.

Cryptocurrencies Make Things Easier for Casino Operators Too

As you can see, there are various ways in which players benefit from this new technology but can we say the same about online gambling companies? In fact, we can sense the blockchain technology makes things easier for gambling operators in a variety of ways.

Most payment methods that use fiat currencies allow for chargebacks but this is not the case where cryptocurrencies are concerned. When one deposits with a digital currency, they have to be extra careful – once the transaction goes through, it is impossible to reverse it or demand a reimbursement. This makes the lives of online gambling operators a lot easier because it spares them the hassles that result from having to deal with player disputes.

Also, casinos that rely on cryptocurrency may end up attracting a solid player base because they utilize an open-source algorithm that is referred to as the “provably fair” algorithm. This technology is exclusive to cryptocurrency gambling and greatly increases the levels of transparency at the online casinos that implement it.

It enables online casino players to check and confirm the games they are wagering money on are 100% random and therefore, fair. This way, when a player spots a Bitcoin casino, for example, they can instantly tell it is legit and unbiased. It makes sense this increased level of transparency works to the advantage of up-and-coming cryptocurrency-based casinos because it helps them build their customer base much quicker.

The online casinos using fiat currencies still outnumber those that rely on the blockchain technology. However, judging by the huge number of benefits the latter offers, it is only a matter of time before more and more casino operators start veering off in this new direction. So to answer our initial question – yes, we believe there is definitely a future for cryptocurrencies in online gambling and this future is now.

Scientists turn carbon emissions into usable energy


A recent study, affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide (CO2), which is the main contributor of global warming.

Published This breakthrough has been led by Professor Guntae Kim in the School of Energy and Chemical Engineering at UNIST in collaboration with Professor Jaephil Cho in the Department of Energy Engineering and Professor Meilin Liu in the School of Materials Science and Engineering at Georgia Institute of Technology.

In this work, the research team presented Hybrid Na-CO2 system that can continuously produce electrical energy and hydrogen through efficient CO2 conversion with stable operation for over 1,000 hr from spontaneous CO2 dissolution in aqueous solution.

“Carbon capture, utilization, and sequestration (CCUS) technologies have recently received a great deal of attention for providing a pathway in dealing with global climate change,” says Professor Kim. “The key to that technology is the easy conversion of chemically stable CO2 molecules to other materials.” He adds, “Our new system has solved this problem with CO2 dissolution mechanism.”

Much of human CO2 emissions are absorbed by the ocean and turned into acidity. The researchers focused on this phenomenon and came up with the idea of melting CO2 into water to induce an electrochemical reaction. If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2.

Their Hybrid Na-CO2 System, just like a fuel cell, consists of a cathode (sodium metal), separator (NASICON), and anode (catalyst). Unlike other batteries, catalysts are contained in water and are connected by a lead wire to a cathode. When CO2 is injected into the water, the entire reaction gets started, eliminating CO2 and creating electricity and H2. At this time, the conversion efficiency of CO2 is high at 50%.

“This hybrid Na-CO2 cell, which adopts efficient CCUS technologies, not only utilizes CO2 as the resource for generating electrical energy but also produces the clean energy source, hydrogen,” says Jeongwon Kim in the Combined M.S/Ph.D. in Energy Engineering at UNIST, the co-first author for the research.

In particular, this system has shown stability to the point of operating for more than 1,000 hours without damage to electrodes. The system can be applied to remove CO2 by inducing voluntary chemical reactions.

“This research will lead to more derived research and will be able to produce H2 and electricity more effectively when electrolytes, separator, system design, and electrocatalysts are improved,” said Professor Kim
