Crypto Wallet Says It Offers 1,000 EOS Accounts for Free

Published

on


A crypto wallet provider says it has launched a giveaway that allows 1,000 users to get a free EOS account.

Lumi Wallet notes the giveaway is taking place on a first-come, first-served basis. Instead of answering quiz questions, preparing a submission or entering into a lottery system, all that participants need to do is sign up in EOS for free. The promotion will end when all of the accounts have been snapped up.

The company says the giveaway is in partnership with Minergate and Changelly, and comes as Lumi vies to become “the premier wallet for the EOS blockchain.”

Lumi has been integrating blockchain into its ecosystem for a while, and in a previous update, the EOS coin was made available in its wallet for the first time.

Diana Furman, the CEO of Lumi Wallet, said: “We decided to make the registration for our users fee-free. Firstly, because we want them to have an easier gateway to EOS. Secondly, because we really do believe that EOS is the platform to check out.”

The executive says she wants Lumi users to be able to explore what EOS has to offer without any barriers in the way, as the blockchain’s development continues apace.

As Lumi continues to align itself closer with the network, the platform is planning to integrate EOS-based tokens, support its decentralized applications (DApps), and implement the EOS voting system within the wallet. To benefit from the giveaway, all users need to do is download the Lumi Wallet app and set up an EOS account for free, the team says.

More tokens supported

Lumi Wallet is available for Android and iOS devices, and currently supports bitcoin, ether, bitcoin cash and most ERC-20 tokens. The company says it strives to ensure that transactions performed through its platform remain completely anonymous, with its team taking great care to ensure the software has an eye-catching design.

Lumi Wallet is available here

New tokens are being added all the time. Earlier this month, Lumi Wallet revealed that more than 900 ERC-20 tokens are now supported — making it easier for users to swap between a range of crypto assets whenever they please.

Lumi is now preparing for its next big step: In the summer, the company is planning to go open-source. According to its team, this upgrade has been much anticipated since it was initially launched.

Game on

The platform also offers a devoted wallet for collectibles, enabling gamers to keep all of their assets and ERC-721 tokens in one secure place. The app is mobile-focused, eliminating the need for players to use special browsers or web extensions in order to access their collectibles.

Lumi Collect has been continuing to add immediate access to blockchain games directly from the app itself — and last month, My Crypto Heroes joined the platform. According to a blog post written by Lumi at the time, the title is one of the largest Ethereum-powered games in terms of volume.

The company says it is poised to capitalize on the “great leap” that is about to be seen in the modern gaming industry. As increasing numbers of players turn to blockchain to see what this technology has to offer, gaming formats are going to change — as will attitudes toward assets.

Researchers Discover How To Automate Accountability On The Blockchain

Published

on

By

“The (virtual) gold rush is on, and as in the Wild West of yore, the outlaws are ever present,” wrote blockchain developers and academics in a recent paper, Polygraph: Accountable Byzantine Agreement. Luckily, these researchers have have discovered a way to detect and punish dishonest blockchain users.

The authors — Vincent Gramoli and Pierre Civit of the University of Sydney, and Seth Gilbert of the National University of Singapore — developed the Polygraph protocol, which automates accountability in blockchains to hold participants accountable for double spending, a notoriously knotty issue in cryptography.

Though the double spend problem was supposedly solved by Satoshi’s white paper, published in 2008, the researchers discovered that disagreements caused by blockchain forks can lead to double spending if the resulting branches have conflicting transactions.

They cite a zombie case:

“Byzantine nodes can override the General Polygraph Protocol by proposing directly two conflicting views to two different clients to then perform a double-spending attack. The coalition does not participate to the consensus in order to violate the liveness property…. Note that safety is also violated: When a client invokes the read() primitive, the coalition can answer arbitrary values, despite the non-termination of the legitimate consensus. The client is supposed to trust the coalition, like all the other clients who can forever receive a different output for the read() primitive. Hence, for t ≥ n − t0, the eventual prefix property is violated. This makes the blockchain vulnerable to a double-spending attack.”

Yes, the paper is scholarly, but it also provides pragmatic solutions to real problems in current consensus mechanisms.

The group considers the growing threat of centralization on blockchains, caused by the collectivizing of hashing power. Under traditional Byzantine protocol agreements, if one party amasses more than one-third of total mining output they gain decision making authority. As an aside, the authors note that the largest Bitcoin mining pool today controls approximately 19 percent of total hashing power.

“We need a new sheriff in town to bring the guilty parties to justice. What if, instead of preventing bad behavior by a party that controls too much of the network power, we guarantee accountability,” write the authors.

Much in the way we prevent crime in the real world, we can prevent bad blockchain behavior via “defense-in-depth” — the basic Byzantine agreement protocol that prevents usurpation if the attacker has less than one-third of network control or if the network infrastructure is working to pass messages in time.

“Byzantine agreement protocols act as the locks on the bank doors, preventing the gangs from making off with the loot,” they wrote.

However, when these guarantees fail — and the authors suggest they can and do — the Polygraph protocol will intercept malicious behavior.

The Polygraph’s basic algorithm is based on the Byzantine agreement protocol, but goes further in that proceeds through asynchronous rounds, or a vote that receives democratic imput.

“First, a reliable broadcaster is used to distribute the proposal values. Then, a second phase of communication is used to determine whether enough processes have converged on a single value. Finally the processes decide, if they can; and if not, they update their estimate in an attempt to converge on a single value.”

This Town Isn’t Big Enough

If the process determines that someone is pursuing illegal actions, the consensus can vote them off the network.

“Accountability has been overlooked in blockchains but it is actually key to security,” said Gramoli, who also serves as Red Belly Blockchain CEO. “The industry cannot accept blockchain to be a simple distributed system where valuable assets vanish as soon as a third of the participants form a coalition.”

Red Belly Blockchain has been funded by the Australian Research Council and developed by researchers of the Concurrent Systems Research Group at the University of Sydney and Data61-CSIRO.

A New Bitcoin Exchange Point On the Colombian-Venezuelan Border Will Help Refugees

Published

By

A new cryptocurrency exchange service is available on the border between Colombia and Venezuela and its aim is to help refugees traveling across the Simon Bolivar International Bridge.

Visitors are now able to use the point-of-sale service with cryptocurrencies to buy goods. The POS is located in Santander, Colombia, just across the border from Venezuela. Panda Group created the payment alternative with refugees in mind. The group, a Columbian-Venezuela joint venture, announced the implementation of the new service through their Twitter account.

According to the data published by Coinatmradar.com, the service lets users exchange using bitcoin (BTC), bitcoin cash (BCH) and dai (DAI), and converts them into to Colombian Pesos (COP).

At the physical location – a small phone service provider in a mall called La Parada – customers can buy bitcoin with prices based on the Localbitcoins rate in pesos. The service will charge 10 percent above the market price and those who sell their bitcoins will do so for 5 percent more than the established market value.

This is not the first cryptocurrency service in the country. The Panda Group has already installed another five cryptocurrency exchanges in Colombia, most of them in the Colombian capital, Bogotá.

According to Panda CEO, Arley Lozano Jaramillo, their solutions are focused on helping the Venezuelan users and they announced the addition of a new service called Xpay.Cash to encourage adoption.

“This service is for all our brothers to pay directly in Cucuta with their cryptoassets and mitigate the loss of exchanging from BTC to COP, which represents a loss of at least 20%,” Jaramillo said.

Colombia has the highest rate of cryptocurrency investors in South America, next to Brazil. There are reportedly over 20 businesses accepting bitcoin payments in the country. The establishments are mainly focused in tourism, food and digital services.

Bitcoin At The Border

The ATM installed in Villa del Rosario City is connected to the Venezuelan border by the state of Tachira. The states are only separated by the Simon Bolivar International Bridge, one of the most heavily traveled borders used by Venezuelan refugees.

The refugee situation has also sparked a focus on the cryptocurrency, mainly for humanitarian aid purposes.

On the other hand, the last point of sale with cryptocurrency was implemented in Cúcuta, another border location with an growing Venezuelan population. The state also has a Bitcoin ATM, one of forty-two in the country.

Crypto analytics firm Coin Metrics partnered with Social Market Analytics (SMA) to collaborate on a feed of real-time sentiment towards cryptocurrency based on social media data, according to a press release on June 17.

The new partnership intends to collect and analyze data posted by crypto community on social media in order to provide a new tool to help crypto traders to track social media sentiment data to build their portfolio strategies.

The new product will initially target sentiment data solely on social media giant Twitter, Coin Metrics CEO Tim Rice confirmed to Cointelegraph, adding that the firms are currently not considering integration of the service into Facebook.

Specifically,Coin Metrics will incorporate the product into market data platform, called the SMA cryptocurrency Sentiment Feed, providing calculated metrics of data on Twitter, according to a report by crypto media outlet The Block. In the report, Rice said that the calculation algorithms would include relevant tweets and calculate “19 different aggregate sentiment metrics down to snapshots of one minute.”

Social Market Analytics is providing social media-powered predictive data analytics to traditional capital markets participants in various markets, including stocks, forex, Exchange-Traded Funds (ETFs), futures, among others. Since its establishment in 2012, SMA has been a Twitter Finance partner, the firm’s CEO Joe Gits stated in an email to Cointelegraph.

Meanwhile, Coin Metrics is backed by major American investment management company Fidelity in February 2019, which participated in a $1.9 million funding round in February 2019.

Earlier today, social media giant Facebook released the white paper for its long-anticipated cryptocurrency and blockchain-powered financial project known as Libra stablecoin.
