Facebook Goes Cold Feet on Libra Cryptocurrency

Facebook is doubtful about the launch of its controversial cryptocurrency Libra.

The social media giant said in its SEC filing that they might not go ahead with their plans due to “significant regulatory scrutiny.” It also noted that Libra could adversely affect its business, reputation, or financial results.

“Market acceptance of such currency is subject to significant uncertainty. As such, there can be no assurance that Libra or our associated products and services will be made available promptly, or at all,”

read the filing.

Facebook said it does not have prior experience with cryptocurrency or blockchain technology, which could affect their ability to successfully develop and market Libra. The firm noted that it was impractical for them and other partners to bear costs for supporting a venture whose future is uncertain from the regulatory point of view. It added:

“We have significant international operations and plan to continue expanding our operations abroad where we have the more limited operating experience, and this may subject us to increased business and economic risks that could affect our financial results.”

The statement followed the congressional hearing of Facebook’s Head of Libra David Marcus this July. Lawmakers grilled the executive with a string of questions about Libra’s intention to replace sovereign currencies. They also cast doubts on whether Libra, like its parent company Facebook, would also become a hotbed of data privacy violations.

Marcus responded that Facebook has no intentions to go ahead with Libra without securing nods from all the lawmakers and regulators.

Bitcoin Rises Ahead of Fed Rate Cut Today

Ethereum at the Core of Microsoft’s Collaborative AI Solutions

Researchers at Microsoft are attempting to create a machine learning distribution model atop the Ethereum blockchain.

Justin Harris and Bo Waggoner are looking to decentralize an otherwise expensive and burdensome process of accessing machine learning systems. In a paper published at Microsoft Research Blog, the duo explains the underlying issues with the current distribution model and why it needs an overhauling using modern techniques like blockchain.

They notice how developers working in the Artificial Intelligence industry constantly require external datasets to create new prediction models. But, due to expensive paywalls, developers find it unable to access them.

Also, published models run the risk of becoming outdated if not fed by new data. Harris wrote:

“We envision a slightly different paradigm, one in which people will be able to easily and cost-effectively run machine learning models with technology they already have, such as browsers and apps on their phones and other devices. In the spirit of democratizing AI, we’re introducing Decentralized & Collaborative AI on Blockchain.”

The researcher utilized Ethereum, an open-source blockchain, to create a network of machine learning scientists. The decentralized framework allows participants to collaborate and continually train and maintain models. Blockchain allows an easy distribution of datasets in real-time, ensuring none of them becomes outdated.

“Leveraging blockchain technology,” wrote Harris, “allows us to do two things that are integral to the success of the framework: offer participants a level of trust and security and reliably execute an incentive-based system to encourage participants to contribute data that will help improve a model’s performance.”

Scalability Issues

Harris recognized they could eventually run into Ethereum’s prevalent scalability issues. Using a blockchain secures information and incentivize participants but, at the same time, reduces the computation power of the overall framework.

Machine learning and AI remains a computation-hungry model, whose distribution could become slower on a blockchain. Harris, though, believes that they would be able to find a solution sooner or later.

“As blockchain technology advances, we anticipate that more applications for collaboration between people and machine learning models will become available, and we hope to see future research in scaling to more complex models along with new incentive mechanisms.”

Overall, a good win for team Ethereum.

Internet Giant Kakao Claims Its Blockchain is 15x Faster than Ethereum

Representatives of the South Korean technology giant Kakao said that their new blockchain, Klaytn, is 15 times faster than Ethereum, reports The Korea Herald.

The internet firm’s blockchain-unit, GroundX, claimed during a press conference in Seoul that Klaytn can process up to 300 transactions per second. On the other hand, the Ethereum blockchain can handle up to 20 transactions per second.

“I believe it would be the initial version of a mobile (blockchain) service. With the reduced response time, many projects that we believed unfathomable could eventually come true,”

said Ground X CEO Han Jae-sun.

Klaytn nevertheless sacrifices a critical element of blockchain systems: decentralization. The feature ensures that no single entity takes control over the blockchain, but GroundX believes the probability of forging records on their ledge is less because of an alternative function.

“To encourage service providers to maintain a stable network, Klaytn features transparent evaluation and incentive mechanisms called Proof of Contribution (PoC) and Klaytn Improvement Reserve (KIR). PoC assesses the contribution level of all economic entities within the Klaytn ecosystem and provides KLAY token that correspond to each entity’s level of contribution. KIR, on the other hand, is allocated for anybody committed to maintaining sustainable ecosystem growth through various activities such as platform research or community events.”

read the GroundX official white-paper.

The primary network of Klaytn was launched in late June. Several large companies, including LG Electronics, LG, Celltrion, and Netmarble, immediately joined the blockchain. Kakao affiliates including Kakao Pay, Kakao Games are also participating.

Bitstamp Now has Its Own Lightning Network Node

Bitstamp, one of the oldest cryptocurrency exchanges in Europe, announced the incorporation of its own bitcoin-enabled Lightning Network into its platform. 

The move will allow Bitstamp users to make faster payments, with lower rates and higher transaction performance than in the Bitcoin network directly.

The company said LN is the next step for Bitcoin and one of the payment systems of the future”. However, the details of the implementation are not as precise as of now. Bitstamp indicated that it currently has 168 payment channels and 156 nodes connected. It pointed out that his own node has a routing capacity of over 7.95531858 bitcoins in total, which is almost $98,000 at the current market rate.

Bitstamp said that by having more nodes in the LN, the network is still active, describing the nodes as their basic building units. As more nodes generate payment channels, the total liquidity of the network increases, which in turn increases the capacity of transactions.

The LN services were also integrated into the main US cryptocurrency exchange service, Coinbase, through Bitrefill, a company that offers recharge services using crypto.

Lightning Network registered a total of 4,462 active nodes on June 3 , which marked a new historic peak in that network of micropayments at the time. The concern that LN becomes a centralized network has motivated to develop increasingly larger channels, as well as the connection of new nodes.

Lightning Network emerged as a scalability solution because it manages millions of bitcoin transactions per second with almost zero commissions.

Bitcoin Analysis 4/7/19: Price Facing Crucial Resistance

Warning! This Android App May Steal Bitcoin from Your Smartphone

Bitcoin wallet addresses do not appear to be something that one can learn and type manually – like a bank account number. They are a long string of random characters which users prefer to copy-and-paste whenever they want to initiate/request money transfer. At the same time, it is evident that not many looks into those pasted bitcoin addresses for potential anomalies.

Well, they should start looking.

Copy, Paste and Steal

Google Play recently hosted a malicious app which was stealing bitcoins from victims’ smartphones. A researcher with Eset found that “clipper,” as the malware is called, was intercepting the content of the clipboard to monitor copied bitcoin addresses. It was then replacing the originally copied bitcoin address with its own. As a result, victims were sending their digital currencies to an address associated with the hackers.

In particular, the malware researchers found had a history of smartphone attacks. Android/Clipper.C was reportedly imitating a genuinely legitimate service known as MetaMask. Primarily, the malware’s purpose is to steal victims’ credentials and private keys to gain control over his Bitcoin and Ethereum wallet. However, Clipper.C could also manipulate clipboards to replace copied crypto wallet addresses.

“This attack targets user who want to use the mobile version of the MetaMask service, which is designed to run Ethereum decentralized apps in a browser, without having to run a full Ethereum node,” wrote Lukas Stefanko, a researcher with Eset. “However, the service currently does not offer a mobile app – only add-ons for desktop browsers such as Chrome and Firefox.”

Stefanko and his team spotted the malware on February 1, 2019, and soon reported it to Google Play security team. As a result, the malware was removed.

Repeated Use of MetaMask among Hackers

MetaMask is a plugin which allows users to interact with Ethereum websites. It enables users to create their 12-word passphrase at the time of installation. This seed word becomes the responsibility of users, mainly because losing it means losing access to crypto wallets.

Recently, MetaMask has become a center of attraction among hackers for the same reason. The lack of education creates security loopholes. It is evident in the malware case as discussed above, in which victims blindly believe an application that imitates MetaMask. The same has happened earlier where MetaMask imitators attempted to steal from the users of websites such as BTC Manager, Games Workshop and Trakt TV.

“The affected sites appear to all use Cloudflare to configure their DNS settings, and this appears to be where the attacker is redirecting the sites to their own imposter sites,” the attacked found at the time of the attack. “Since this has affected multiple sites, if you are using Cloudflare, you should be extra vigilant. Some of the sites had 2FA for all of their users, but the settings were updated by API using their API keys.”
