blockchain startup launches app to encourage people stay at home amid covid19

Crypto- and blockchain-focused companies around the world have been making efforts to support people amid the coronavirus pandemic, with some of them donating funds to nonprofits and providing supplies to hospitals.

Israeli blockchain startup “Orbs” came up with an idea to encourage people to self-quarantine by using a newly launched app.

The app, which is dubbed “Stay at Home Challenge,” is designed to assure that the user does not leave the nearby radius once they enter their location in the app. The app tracks users’ self-quarantine time and notifies them when they abandon the designated home area, according to an announcement on April 21.

A gamified way to trace people’s movements

The app gamifies the self-quarantine concept, allowing users to share their progression with friends and family members, thus encouraging them to stay at home as well.

Although the app tracks people’s movements, “Orbs” claims that it doesn’t collect any personal data as users don’t add their name, email or any other personal information in the app. Currently, the app is available in Google Play, and soon will be available for iOS users. “Orbs” told Cointelegraph:

“We will continue to think of ways we can help out in Israel and globally to get us all through these challenging times. We discuss ideas on a regular basis in company meetings and chats.”

Tracking people is a new normal

Stay at Home Challenge is not the first app that tracks users’ activity under the umbrella of the coronavirus-related quarantine. A team of academics at the University of Cape Town in South Africa developed a blockchain-powered app geared to allow users to verify their own COVID-19 status. The application intends to improve contact tracing of infected patients.

In late March, Russian authorities rolled out their own tracking application for patients who test positive for COVID-19 in Moscow. The app reportedly requests access to users’ calls, location and camera, as well as network information.

China also released an app in February that allows users to check whether they’ve come into contact with a person who is potentially infected with COVID-19. The app shares users’ location data to a centralized server whenever their barcodes are scanned at a checkpoint either in public transport hubs or other access-point controlled areas.

“Zoom Scandal Data” shows that Blockchain may be the future of communications

As people around the world started following shelter-in-place orders, popular video conferencing platform Zoom quickly gained new users, noting in a recent blog post that it had reached more than 200 million daily users last month, up from 10 million in December. From virtual conferences to online birthday parties, thousands of individuals have flocked to Zoom in an attempt to remain social at a time when social gatherings are banned.

Yet, while Zoom may have seemed like the perfect alternative to in-person gatherings, a major security flaw has been lurking in the system. Following the sudden balloon in daily users, it was discovered last week that thousands of personal Zoom videos have been left viewable on the open web.

What’s the issue?

Ankit Bhatia, CEO and co-founder of the Sapien Network social platform, told Cointelegraph that signing into Zoom has never been a secure process:

“If you know the server the Zoom call is on, then you only need to run a script to generate the right sequence of numbers at a given time and you’re potentially in on a conference, be it a daily technical standup or an AA meeting. This is especially easy when Zoom users don’t password-protect their meetings.”

In addition to strangers having access to “private” Zoom videos, personally identifiable information such as email addresses and passwords have also been compromised.

Jeff Pulver, Voice Over Internet Protocol pioneer, told Cointelegraph that the main issue with all major communication services like Zoom is that it uses centralized data storage mechanisms. Due to this, Zoom poses security threats to the confidential information it gathers. He explained:

“Companies like Zoom say they cannot access user data, but they still mine the data generated by those apps, such as how often users talk to someone and whose phone numbers they have stored in their smartphone’s address book. Routing all business and personal data through a centralized server with one main point of contact poses an overwhelming number of threats for information security.”

Pulver, who authored the “Pulver Order” adopted by the U.S. Federal Communications Commission to ensure that users need not pay for communication apps such as FaceTime, understood early on the data issues posed by Zoom. He noted that the thousands of data breaches witnessed between 2018 and 2019 should have been a global wake-up call for people who are looking to better understand how their data was being used by third party platforms.

Blockchain can power a new era of communication

As such, Pulver believes that the best way of making high-security communications services universally available is through the use of blockchain technology. “By refraining from centralized control, we will be removing the weak link from the equation — the third parties,” he explained. Pulver has spent the past year developing a blockchain-based communications network called Debrief.

Unlike conventional video applications, Debrief is an open-source blockchain network upon which communication applications can be built. According to Pulver, leveraging blockchain creates a higher level of security when it comes to users’ personal information:

“Unlike Facebook Messenger or Google’s Hangouts, Debrief encrypts user messages by default and also retains virtually no information from users, including messages and address books, on its servers, since they are decentralized.”

Karen Sun, Debrief full-stack developer and former solution configuration manager of Ericsson, told Cointelergraph that, “Even if our servers get hacked, the perpetrators will not be able to decrypt the messages stored there.”

According to Pulver, Debrief has been primarily built for fast and private transactions. Unlike mainstream public chains like Ethereum, the Debrief infrastructure has been constructed to ensure fast and trusted connections specifically for communication. Pulver further noted that Debrief contains an open-source Middleware component, allowing for mainstream centralized applications such as Zoom to utilize Debrief’s blockchain “by wrapping their code into our code.”

While the Debrief Testnet privately launched in February 2020, Pulver mentioned that the MainNet launch is expected in the fourth quarter of this year. The Middleware public launch is also projected for the same period.

A video conferencing DApp

For use in the meantime, Pulver explained that a decentralized application has been built on the Debrief network. The DApp provides HD video conferencing, peer-to-peer audio and video calling, messaging, decentralized file storage and more. The beta version of Debrief has just been released, which has already seen over 1.2 million transactions from over 3,000 participating users.

Pulver mentioned that the challenge moving forward will be generating public awareness for blockchain-based communication networks, adding, “We need to find developers who want to use our blockchain to see what they are able to do with the APIs.”

Additionally, regulatory and data standard challenges might also hamper the adoption of a blockchain-based communication network. A recent Telecoms Tech article highlights these challenges, stating,

“The current telco industry adheres to a set of data standards, structures, and transmission infrastructure. As such, bringing blockchain applications to this existing framework presents significant challenges.”

Pulver, however, remains optimistic, saying:

“We have the ability to bring this to the communications industry and my hope is to get thousands of people to connect and innovate in a positive, secure way.”

Wishes for Happy Easter

The last 2 months have found us locked up in our house trying to face an invisible enemy named “Coronaios”

Without discriminating against who will hit whom, man or woman, rich or poor, young or old, he continues even today, sowing panic and fear both for today and for the effects of tomorrow. So we took a breath before the Holy Easter days to be home and not be able to go anywhere, not even to our loved ones.

“We Greece”, wanting to pass on its own message of love and hope, wishes you and your families good health and not to lose hope for a better tomorrow.

“Even through these difficulties that we all experience, there are positive things to see and understand that nothing can be a given. To feel the loss of care, love, freedom, joy, smile, health, company, friendship and much more to appreciate.

Now we know how important it is that today we cannot have and think about tomorrow how we will be and what we need to change. Change must be us for ourselves and so some things around us will change.

So “We Greece” wishes the Resurrection of the Lord to find us stronger and healthier, wiser and more open-minded but also more ready to face challenges, giving us the opportunity with our choices to set a better tomorrow.

Blockchain wallets hit over 47 mln users globally

The number of blockchain wallets doubled over the last two years, reaching more than 47 million users globally in 2020, according to data gathered by Finanso.se.

Blockchain wallet allows users to manage and store cryptocurrencies such as Bitcoin, Bitcoin Cash, Ether, and Stellar. Statistics show the number of people using these crypto wallets has been rapidly growing over the years.

In 2016, there were nearly 11 million blockchain wallets in the world, revealed the Statista data. By the end of 2017, the number of their users grew by 95% and reached 21.51 million globally. The noticeable rising trend continued in the last two years, with the number of blockchain wallets jumping over 44.5 million at the end of 2019. Statistics show the number of users increased by over 12 million in 2019 only.

Statistics indicate the number of Bitcoin and Ether daily transactions, as the two leading cryptocurrencies managed by the blockchain wallet, fell at the beginning of 2020 reaching 301,000 and 577,000, respectively. However, the number of Ether transactions has been on the rise for the last three months, jumping over 735,000 in April 2020.

As the most significant name in cryptocurrency in terms of both market cap and price index, Bitcoin reached 325,000 daily transactions in March 2020. Still, the recent data show Bitcoin investors became more interested in keeping their funds safe in personal wallets than on exchanges, as the number of daily transactions fell under 275,000 in the first week of April 2020.

Jack Dorsey donates 28% of his wealth to global covid 19 relief

Twitter CEO and Square founder Jack Dorsey has started a new fund called Start Small LLC, aimed at fighting COVID-19. He’s seeding the fund with $1 billion, roughly 28% of his wealth. He shared the news via Twitter:

jack-dorsey-donates-28-of-his-wealth-to-global-covid-19-relief

The fund’s efforts will initially focus fighting the global pandemic currently dominating the news cycle, but will eventually switch to providing money for girl’s health, education and universal basic income (UBI) initiatives. Dorsey is really putting his money where his mouth is when it comes to taking action to improve the world:

“I believe they represent the best long-term solutions to the existential problems facing the world. UBI is a great idea needing experimentation. Girl’s health and education is critical to balance”.

He promises that all the funding will be transparent, and further notes:

“The impact this money will have should benefit both companies over the long-term because it’s helping the people we want to serve.”

Dorsey is a known Bitcoin supporter. He recently suggested that Square’s CashApp should be used to distribute the U.S. stimulus package. Meanwhile, Bitcoin remains one of the few strong revenue generators for CashApp in the face of the crisis.

Italys top news agency uses blockchain to fight fake coronavirus news

Amid the global pandemic crisis, the importance of ensuring trusted information is getting more crucial as fake coronavirus news poses a direct threat to life and health of people worldwide.

While some global jurisdictions are imposing fines and imprisonment for spreading false coronavirus information, a major news agency in Italy is hoping to stop fake news by implementing blockchain technology.

All the news that’s fit to hash

ANSA, Italy’s main news agency and an international publication owned by 24 national newspapers, has launched a news tracking system based on blockchain to bring more trust between the company and its readers. Called ANSAcheck, the blockchain-powered tool purportedly allows users to verify the origin and history of news published on its platforms, its affiliated publications as well as third parties such as social media or other platforms, ANSA announced on April 6.

Additionally, the technology implementation allows ANSA to keep track of its content use and link ecosystem actors, publishers and web agencies, the firm said.

ANSA readers can verify articles with blockchain by clicking on a special label

According to the announcement, the system was developed in collaboration with Big Four accounting firm Ernst & Young. Specifically, the system provides a news article with a tracking label “Notizia d’origine certificata” (“News of Certified Origin”). The label links a news piece to a page containing details like date and time of recording or publishing the article, registered blocks for relevant events, as well as links to relevant blockchain transactions on blockchain browser Etherscan.

ANSAcheck is based on Ethereum

According to a local ANSA report, the ANSAcheck system is based on Ernst & Young’s proprietary EY Ops Chain Traceability solution, which is based on the Ethereum blockchain. Particularly, the platform is implementing smart contract technology by linking a news article to a digital representation and creating a specific cryptographic string, ANSA noted.

As previously announced, EY Ops Chain was launched in April 2017 in order to enable enterprises to represent their operations on a blockchain using digital tokens and smart contracts.

Stefano de Alessandri, CEO at ANSA, outlined that the news agency has become aware of frequent fraudulent use of ANSA brand to provide false information. The executive noted that ANSA is the first agency to implement the tech to tackle the problem:

“We are therefore particularly proud to be the first to launch a highly innovative project, carried out for all our readers and the clients of the Agency […] Starting today, we can track the origin of the news and – at the same time – support the professionalism of our journalists.”

India is Developing Blockchain Based Voting Solution

The Election Commission has partnered with the Indian Institute of Technology to create a Blockchain voting solution in India. The system will allow citizens to vote outside of their city of registration while preventing them from voting more than once.

18 February, 2020 | AtoZ Markets – In the 2019 elections, 300 million voters did not vote. It represents a third of the 900 million Indian voters. Some were probably not engaged enough to vote. But the vast majority may not have been able to vote – because they were far from where they were registered as voters.

Election Commission of India Will Use Blockchain Voting Solution

The country has more than 450 million migrants who move for work, education or marriage but do so only temporarily. Most of them do not bother to re-register in a new district.

Indian citizens will soon be able to vote outside their registration city due to the Blockchain Voting Solution. According to the Times of India, on February 13, the Indian Chief Election Commissioner, Sunil Arora, said:

The country hopes to increase voter turnout through a blockchain voting solution.

The commissioner said regulators are working with the Indian Institute of Technology to develop a blockchain voting system that would allow citizens to vote remotely. He also hopes the chain voting system will be in place during his tenure, which ends in April 2021.

He also said that a proposal to link voters’ identity cards with Aadhaar, is pending at the Ministry of Justice. It would be on the list during the Election Commission, EC’s deliberations on electoral reforms with the ministry.

The blockchain used by the system to allow citizens to vote outside of their registration city. It also prevents them from voting more than once.

The Fear of Hacking in Digital Voting

While paper ballots seem old-fashioned to some. Many oppose the idea of digital voting for fear of hacking. Arora said that if machines can “malfunction” like any other electronic device, they cannot be “tampered with”. He also said that if the EC was open to constructive criticism, people should refrain from criticizing for “pleasure”.

The Massachusetts Institute of Technology’s security analysis of Voatz the self-styled first internet voting application used in US federal elections, has resulted in allegations of cybersecurity vulnerabilities.

The CEC admitted that the daily dialogue had become “coarser.” It should be “avoided.” But if the commission had, in the past, and was still going to hold talks with political parties. The talk is to give “more muscles “to the model code, the decision, ultimately, should be voluntary.

China: Βlockchain deployment rises amid coronavirus outbreak

Amid the ongoing coronavirus epidemic, China has turned to blockchain technology to manage medical data, track supply of virus prevention materials and consult the public.

For the first two weeks of February, China saw the launch of as much as 20 blockchain-based applications designed to help fight the coronavirus outbreak, domestic news outlet People’s Daily Online reported on Feb. 17. Most of the apps are used to manage citizens’ personal data as many people are returning to work this month.

Blockchain is on guard for medical data security

Local authorities noted that blockchain lets them effectively track and secure collected information. Thus, Xi’an, the capital of Shaanxi Province, applies the tech for online consultation and screening, as well as securely manage health records. In Hangzhou, tech company Vastchain Technology rolled out a WeChat-based program dubbed Access Pass. The program generates a QR code that residents can use to enter gated communities.

In collaboration with the Zhejiang Provincial Health Commission and the Economy and Information Technology Department, mobile and online payment platform Alipay introduced a platform that enables charity organizations and initiatives to collaborate more efficiently and transparently.

Specifically, the app allows users to track allocation and donation of relief supplies, as well as the review, recording and tracing of demand and supply chains of medical supplies.

Coronavirus’s impact on businesses

The coronavirus has indeed compromised the normal course of things in Asia, forcing a number of cryptocurrency-related conferences to postpone. Hong Kong-based blockchain remittance startup Bitspark also abruptly announced its closure. The closure came along with the coronavirus outbreak in China and anti-government protests in Hong Kong, where Bitspark’s headquarters is located.

Crypto mining firms such as Bitmail, MicroBT and Canaan also published notices on their websites of delays in their after-sale services due to the outbreak of the virus.

As Cointelegraph reported earlier in February, insurance firms in China use blockchain to manage coronavirus-related claims amid the outbreak. Thus, online mutual aid platform Xiang Hu Bao added the coronavirus to the list of illnesses eligible for a maximum one-time payout of around $14,300 (100,000 yuan).

Blue Cross Insurance, owned by the Bank of East Asia is reportedly helping to decrease the bureaucratic impact of the coronavirus outbreak with a medical claims app.

In the meantime, it has been reported that China started a quarantine of its used bank notes to try to stop the spread of the coronavirus.

Ένα εκατομμύριο εισιτήρια UEFA πρόκειται να διανεμηθούν μέσω του Blockchain το 2020

Soccer fans in Europe will join the ranks of early blockchain adopters thanks to a new initiative by the Union of European Football Associations (UEFA).

According to a Feb. 17 announcement, UEFA will distribute over one million soccer match tickets via a blockchain-enabled mobile application. The organization claims that this new ticketing system will make “entry into the stadium smooth, safe and secure.”

The new blockchain-based mobile ticketing solution is meant to prevent the duplication and replication of tickets by “QR codes only being activated by Bluetooth once fans are in close proximity to the stadium.” The app will be available for download toward the end of May for both Android and iOS devices.

Tickets will be delivered no later than seven days before the match and “UEFA” expects to deliver over one million mobile tickets to fans across all 51 matches.” UEFA decided to adopt this system in an attempt to facilitate ticket distribution to what is expected to be the most in-demand UEFA cup ever.

UEFA also stated that digital ticketing will help curb paper consumption and be more convenient for soccer fans:

“Supporters who purchase ‘Follow my team’ tickets will receive their mobile tickets only once their team has qualified for a specific match. The ability to deliver mobile tickets to fans close to matchday will considerably enhance the fan journey, as fans will no longer be required to visit ticket collection points to exchange ticket vouchers. ”

The initiative builds on the successful deployment of the mobile ticketing system in August 2018 for the UEFA Super Cup soccer match between Real Madrid and Atletico Madrid held in Tallinn, Estonia.

Blockchain’s the ticket

Many sports franchises and event organizers are turning to blockchain for ticketing, as the technology promises to be a highly-effective way to prevent forgery and ensure convenience.

As Cointelegraph reported in December 2019, Ticketmaster’s vice president of blockchain products Sandy Khaund said that the technology can prevent secondary ticket markets from popping up and ensure that “tickets end up in the right hands.”

The CEO and founder of EventChain, Ashton Addison, told Cointelegraph:

“The whole point of implementing blockchain in the ticketing industry is to bring back fairness to the artists, event organizers and fans. For example, a major problem facing the industry is counterfeit tickets. Blockchain can prevent this by allowing attendees to verify the authenticity of their tickets. This also turns tickets into scarce digital assets, which are unable to be double sold.”

Barcelona scores on cryptocurrencies

Many teams have entered the cryptos court. Millions of followers can experience the benefits of the new digital economy. How does a collector’s currency work, like that of Barcelona. What the profits.

Barcelona, the football team with the most fans in the world, gets its own cryptocurrency, ” Barça Fan Tokens ”. However, this is not the first popular club to join the digital economy through the issue of collector currency. Juventus, Paris Saint-Germain, Atlético De Madrid, Galatasaray, Roma and West Ham are ahead!

Let’s get it right from the start, and first of all explain what ‘token’ means. It is a digital asset that certifies that the person holding it is also the owner of a value. A token can represent a currency, percentage of ownership of a property, 1% of a painting, shares or shares of a business. Converting a digital asset into a token is like the classical process and logic of issuing a bond. But this is an advanced technological process.

Now let’s see in practice how a token works like Barcelona. From our mobile phone, we go into the ‘Play Store’ or ‘Apple Store’ and download the ‘socios.com’ app. To activate it, he first asks for our phone number to send a confirmation code and then an e-mail.

Before you can buy collector coins from the group you are interested in, you first need to buy a cryptocurrency called Chiliz (CHZ), which is ranked # 86 in terms of capitalization at ” coinmarketcap.com ”.

The easiest way, though not necessarily the most economical way to buy CHZ, is to go to the Wallet icon. From there you select Top-up, where you can purchase the amount you want through your debit card.

With CHZ, you can buy the limited edition coins of your choice. Barza Fan Tokens (with the BAR symbol) is not available yet. From what we have been told, it will come out in the second quarter of 2020. There will be 40 million Barça Fan Tokens available, each costing 2 € as the starting price. However, coins from the other groups mentioned above are available.

In other words, CHZ functions like the casino chips. Like there, to play roulette, you can only bet on chips, not euros, so in the ” socios.com ” application you do not buy your team’s currency directly. First you need to convert your euro into CHZ.

How do you make money from this process? One way is to raise the value of Chiliz. Based on what we see at ” coinmarketcap.com ”, so far half of the Chiliz is expected to be released.

As we can see in the chart below, it has been trading publicly since July. Except for the first few months, from September onwards the volume of transactions is at least 2-3 million daily, and since the announcement of cooperation with ‘Barcelona’ it has been trading between 10 and 40 million. So we won’t be trapped looking for buyers if we want to sell them.

barcelona token

The second way is to raise the value of the coins of the group you bought, which you can liquidate at any time and convert them back into Chiliz. You can of course get another team later, if you wish, before making the euro.

In addition to the market, as we are told, there will be some tokens that will be distributed free of charge. One way is through the ‘Token Hunt’. An application that we see is very much like ” Pokémon Go ”, the ‘Nintento’ online game where you search and hunt for virtual figures. The difference with other digital games is that you look for virtual figures in places that actually exist, not in some fantastic location.

But in addition to the potential economic benefit, it allows fans of big clubs around the world to interact with the club itself. To influence his decisions. Owning tokens gives their owners the right to participate in polls for the daily activities of the groups. The platform rewards fans for their participation and enables them to win prizes.

The implications of this application for disseminating and updating the capabilities that cryptos provide are obvious. Millions of followers, and not just around the world, will experience the benefits of the new digital economy that cryptocurrencies can offer.

The disadvantage of the application is that it does not (yet) have Panionios. But on the other hand, is it a good idea to buy CHZ, because the idea is good and will increase demand, especially if other teams join the platform? The only sure thing is that besides Chiliz, there are other smart business plans among the 5,000 altcoins traded on the exchanges. Like many that are useless or scams.
