Bernanke at Ripple Event: Blockchain Has 'Obvious' Benefits in Payments


Former Federal Reserve chairman Ben Bernanke is bullish on blockchain.

Speaking at Ripple's Swell conference in Toronto today, being held the same week and in the same city as Sibos, the annual gathering hosted by Ripple's rival Swift, Bernanke told a room of several hundred attendees that he believes payments can be slow and expensive as designed using existing tools today.

Bernanke, who led the U.S. central bank during the 2008 financial crisis, outlined the complicated process it would take for a bank in Germany to send a payment to a bank in the U.S., before saying:

"It's an obvious area where new technologies like blockchain or these electronic currencies can be used to improve the process."

Bernanke, now a distinguished fellow in residence at the Brookings Institute, called out Ripple by name, saying that he's read about the company's work and thinks that any effort in payments to reduce cost, improve accuracy, speed and reliability and "bring the global economy closer together" is a good thing.

While the conversation mostly focused on monetary policy, Bernanke was asked to comment more on cryptocurrency and blockchain during the question-and-answer session, and his responses should come as no surprise as he gave bitcoin both muted praise and criticism as far back as 2015.

Echoing those past statements, Bernanke said, "bitcoin is meant to be an attempt to replace fiat currencies and evade government regulation and government intervention."

And that attempt, he contends, won't succeed because governments won't allow it. "When bitcoin becomes a threat they'll take whatever action" deemed necessary to quash it, he said.

Unlike bitcoin, which works against regulators, he continued, blockchain businesses that collaborate with governments will likely see more momentum in terms of innovating on the payments system. Central banks around the world (including in Singapore, theU.K. and Europe) have taken more of an interest in blockchain technology recently, trying to figure out how it might create efficiencies within their systems.

Case in point: earlier this month, senior vice president at the Federal Reserve Bank of Boston Jim Cunha said blockchain and other fintech startups would be pushing incumbent financial institutions and middlemen to be more innovative in their approach.

When asked if bitcoin, other cryptocurrencies and blockchain might affect monetary policy, Bernanke said he doesn't see that happening.

Bernanke said:

"It could be a lack of imagination, but I don't think monetary policy has changed that much. [Central banks] are supportive of these new technologies because they'll improve the payment system ... but it won't affect the ability of the Fed to require a certain amount of reserves of affect interest rates."

JPMorgan Launches Interbank Payments Platform on Quorum Blockchain


Wall Street banking giant JPMorgan Chase is launching a new interbank payments platform powered by blockchain, the firm announced today.

With the participation of two other banks – Australia-based ANZ and the Royal Bank of Canada (Australia) – the Interbank Information Network (IIN) will be built on Quorum, the ethereum-based blockchain network first unveiled last fall. Additional institutions are expected to join the initiative in the coming months, with a specific focus on the correspondent banking market.

Emma Loftus, head of global payments and foreign exchange for JPMorgan Treasury Services, said in a statement:

"IIN will enhance the client experience, decreasing the amount of time – from weeks to hours – and costs associated with resolving payment delays. Blockchain capabilities have allowed us to rethink how critical information can be sourced and exchanged between global banks."

It's a notable application for the bank, given that its treasury services clear trillions of dollars in transactions per day. Previous reports, including a February 2016 story from the Wall Street Journal, indicated that cross-border payments had emerged as a key use case area for the bank.


And in spite of its CEO's anti-bitcoin stance, the cryptocurrency's underlying tech has been an area of growing focus for the bank in the past year, as seen in its work with Quorum as well as initiatives like the Hyperledger Project and the Enterprise Ethereum Alliance.

Priced In? Ether Sees Cautious Boost as Blockchain Upgrade Underway

Ether prices rose to a six-week high of $350 today as ethereum, the second largest blockchain by total value, appears to have successfully executed a widely anticipated software upgrade.

The first part of a larger technology update called "Metropolis," the "Byzantium" code was enacted this morning Eastern Standard Time with minimal contention as anticipated by developers. For now, this means ether's price has put a serious headwind behind it – the next so-called hard fork, a risky software upgrade that opens up the possibility new blockchains will be created, isn't expected until 2018.

In response, the ether-US dollar (ETH/USD) exchange rate surged in value in the run-up to the event.

Prices rose from $298 to $345 on Oct. 13 reportedly due to a high degree of confidence among investors, though the record rally in bitcoin could have pulled ether prices higher as well.

At press time, however, indications are the upgrade is unlikely to be winning new market interest. Despite the smooth implementation, ether prices are struggling to break above $350 levels. The loss of bullish momentum indicates the market may have priced-in the implementation.

Furthermore, ETH bulls might be staying on the sidelines in search of more evidence the software has achieved stability.

Still, the price action analysis favors upside in ether. At press time, ether is trading at $342; up 5.5% in the last 24 hours. Week-on-week, the cryptocurrency is up 13.15%, while month-on-month, it is up 30%.

Dayli Chart



The chart shows:

Dip demand: Sunday's candle had a long lower body (also known as lower shadow or wick). Prices usually move in the opposite direction after a long wick makes an appearance. No wonder, ether rose to $350 levels today.
Bullish break of the sideways channel.
Bullish 14-day relative strength index.
View

The outlook remains constructive – it may be only a matter of time before ether breaks above $350 and extends the rally to $370-380 levels.
On the downside, only an end of the day close below $320 (previous day's low) would abort the bullish view on the daily chart.

Crypto Mining Makes Millions for Gold Mining Maverick


Frank Giustra, a well regarded Canadian mining magnate who created one of the world’s most successful mining companies is now moving his operation digitally to mine Cryptocurrency.

Giustra has backed a Blockchain technology company called Hive Blockchain Technologies, which is among the first publicly traded stocks to provide exposure to crypto mining, and for Giustra, he is seeing huge returns.

Six fold returns
The mining mogul has seen rapid growth since entering the Bitcoin market, backing Hive which was previously known as Leeta Gold Corp.

The decision to dig for data servers has paid off as Hive’s shares have soared about 633 percent, giving it a market value of $443 mln since it took over the listing.

Giustra’s foray into the crypto space has been a successful one as he has help drive Hive to be one of the pioneers in terms of a listed crypto mining company.

Hive paid Hong Kong-based Genesis Mining, builder of the world’s largest Ether mining facility, $9 mln and gave it a 30 percent stake to acquire a new data center in Reykjanes, Iceland.

Major mining operation
Hive’s mandate is to expand into other colder countries, such as Iceland and Sweden, in order to mine different coins and amass an inventory which they hope will appreciate. It is with the help of Giustra that they hope to achieve this.

Giustra helped build the company that would become Goldcorp Inc., then founded film studio Lions Gate Entertainment Corp. He counts Bill Clinton and George Soros among his close connections. Those connections may position him to grasp a nascent corner of finance and navigate Bitcoin’s uncertain regulatory waters.

Still a niche market
Despite the visible success seen from Giustra, companies like Hive are still very much in the minority, and while their pioneering moves are believed to make the market more open and available, there are still those who believed it is niche.


“I suspect the vast majority of accounts aren’t contemplating an investment in virtual currencies right now,” said Jeff Klingelhofer, managing director of Thornburg InvestmentManagement Inc.

IBM Blockchain Payments To Use Stellar In Major Partnership Deal


IBM and payments network KlickEx have announced Stellar as the backbone of its new “cross-border payments solution.”

In what it describes as the first use of public Blockchain technology “being used in production to facilitate cross-border payments in multiple integrated currency corridors,” IBM is already convening a group of big banking partners to further the initiative.

“Currently, cross-border payments take up to several days to clear,” Stellar co-founder Jed McCaleb said in an accompanying blog post.


“This new implementation is poised to affect a profound change in the South Pacific region, and once fully scaled by IBM and its banking partners, could potentially change the way money is moved around the world.”



KlickEx already has an extant payments network operating in Southeast Asia from its base in New Zealand.

Now, a group of “diverse banking leaders” will assist in the”development and deployment process” of the Blockchain-backed solution, which is already in active use, IBM states.

The move sees a significant implementation for Stellar within the global financial framework of legacy institutions, putting it alongside Ripple as one of the principal entities in Blockchain-based institutional settlements.

This caps a year of outreach initiatives, with marketing ploys such as a grants program and the release of the Lightyear spin-off hoping to attract wider attention and participation from investors.

Ethereum's Byzantium Hard Fork Is Running Smoothly, Developers Say


While it's still perhaps too early to deem ethereum's Byzantium upgrade a success, developers indicate the software update, is running smoothly so far.

An official release manager for Byzantium, Hudson Johnston, noted that the new software is now stable, and steadily rolling out across the distributed network, a fact he said can be attributed to "the hard work (of) developers, users and miners across the ethereum ecosystem."

But while the impact on ethereum's infrastructure will be substantial, it looks like the network is undergoing an adjustment period. Currently, some blocks are being mined in as little as 1 second, though others are dragging out to nearly a minute – substantially longer than the long-time average of 25 seconds per block.

Further, blocks are filling with relatively high numbers of transactions. That's good news for scalability, as ethereum can, in theory, continue to grow without slowing down the network.

According to the ethereum forktracker, mining on the old blockchain with the older ruleset has ceased. This is also positive news for ethereum, as it means a relatively low chance that a competing currency will be introduced, as happened last summer when a split produced the rival asset, ethereum classic.

That said, according to ethereum developer Afri Schoedon, there's still a chance that someone is mining the old blockchain, but probably at very high cost.

In the days prior to the fork, developers and node operators (such as mining pools) were given some last-minute toil, as faults found in Byzantium software led to continuous re-releases. The issues saw ethereum developers working around the clock to get the corrected software out on time, and node operators working over the weekend to install the updated software.

At press time, a high proportion of nodes are yet to install the Byzantium update, though the figures are slowly changing and an ongoing trickle of nodes is arriving to the hard fork fashionably late.


Although the price per dollar of ether dropped somewhat in the run-up to the fork, prices peaked close to the monthly high of $350 immediately after, according CoinMarketCap. At press time, ether prices have dropped back to $337 – the same level seen immediately prior to the fork.

Hours to Go: How to Watch Ethereum's Fork as It Happens


With $30 billion on the line, all eyes are likely to be on ethereum tomorrow as it seeks to navigate one of its biggest-ever updates.

Will all software users upgrade to the updated blockchain? Or will a new, competing token be created? That's exactly what the market is watching and waiting to see when etheruem hits block 4,370,000, scheduled to occur tomorrow at around 6:00 UTC at press time.

The first part of a larger, multi-part upgrade, the so-called "Byzantium" code will make the blockchain lighter and faster, paving the way for better decentralized applications (dapps), while also enhancing network privacy.

New features aside, however, ethereum developers are mostly optimistic about the upgrade. Although developers on the most popular clients have had to iron out a pair of bugs in the days leading up to change, there's confidence that the upgrade will be smooth.

New and seasoned investors won't likely want to take others' word for it, however. So, if you're eager to see for yourself, here's how to monitor the update in real time:

Fork countdown

Adding uncertainty to hard forks is their reliance on block numbers as a way to signal upgrades. Simply put, rather than have everyone change their software at a specific time, users rely on the numbered blocks in the blockchain itself as a means of coordinating.

Because of this, no one knows exactly when the hard fork will take place. Yet, that doesn't mean there's no way to keep an eye out.

To track when this block number will be hit, Singapore-based smart contract company CodeTract has released a fork countdown, showing how many blocks remain and roughly, how much time is left until the fork occurs.

By current projections, the hard fork looks like it will execute on early Monday.

Mining hashrate

Once the fork happens, users will want to track how much of the ethereum ecosystem moves over, and how quickly they do so.

This is a key metric to track. As long as miners are mining on the old version of ethereum, it will remain operational (and valuable). If that persists for long enough, it could lead to a split (although ethereum developers think this is unlikely due to specifics in the code).

Developers aren't going in blind either – already, the Byzantium code has undergone testing to give an idea of how the fork would play out. For example, earlier this week, all minerson a test version of the network made the migration, a small (but encouraging) sign of what to expect.

The best way to watch this is on the Ethereum Foundation's website, which will show what percentage of ethereum miners that have moved over to the new blockchain when the fork happens.

Nodes

But, miners are not the only stakeholders in ethereum who need to upgrade; developers, users and companies running nodes, which store a full copy of the ledger, also need to download new software or risk falling behind.

Ether Nodes tracks how many node operators are running clients compatible with Byzantium.

Geth, the most popular ethereum client, released fork-ready software in version 1.7.2. And Parity, the second most popular client, released 1.7.6, which is compatible and fixes some consensus bugs.

Right now, 60 percent of Geth nodes and 27 percent of Parity nodes have upgraded to a hard fork-compatible version. With under a day left before the fork, most node operators still need to upgrade.

Price

Of course, there may be more immediate reasons you're worried about a split.


If money's on the mind, you can always be sure to monitor the price of ether. For that, you can turn to our ethereum price page, which will update in real time as the fork happens.

Can Blockchain Technology Challenge YouTube, Netflix?


Online video content is already a huge industry. Giants like YouTube have effectively controlled the marketplace to such a large degree that they have become ubiquitous for content consumption globally.

While these massive corporate giants have created platforms that allow users access to a wide swath of streaming video content, some cracks in the business model have started to show up.

Companies like YouTube are being called to task because they have been able to monetize creator content without paying the actual creator anything but ad revenue. While YouTube profits on the content that is uploaded, the actual creative genius behind the content is kept at arm’s length, and forced to essentially sell advertising for the platform in order to make money.

“There are no assurances that creators will make money out of their content - even if these go viral. This is, unless they have a specific monetization mechanism in place. However, these services benefit from everything users generate.”

And companies like Netflix are being critiqued for their general content control, keeping users from watching what they want. Available content is currently tightly controlled by the video streaming platform. Companies like Netflix have almost authoritarian control, keeping users within the confines of a limited supply of videos to stream. The monthly service charges also means that the company is paid regardless of how much content users consume. A user who watches one video a month is charged the same as a user that watches 100.

Blockchain for creators
Blockchain technology seems to have the answers, according to a recent article in Forbes. The distributed ledger platform allows users the chance to upload and then monetize content individually, without paying a centralized corporate hub. According to the author:

"Video marketplace StreamSpace is one platform challenging video on demand and advertising-driven streaming services by allowing filmmakers the ability to sell their works directly through Blockchain. Another is Flixxo that combines Blockchain and torrent technology to create a video sharing platform with a revenue sharing model for its community.”

By building a peer-to-peer access network and monetizing content within the platforms, these companies are using Blockchain technology to move funds back into the hands of the creators and users.

User freedom
Decentralized platforms allow users more freedom as well. Because the decentralized platform gives users choice, they are able to remove things that have become almost commonplace in the video streaming world like ads before, during, and after the video.

Further, users have autonomy over what data they want to watch. Anything that is created and uploaded can be consumed, without the oversight of a centralized platform like Netflix.

In a decentralized peer to peer platform, users also would have the ability to contribute to creators they appreciate or whose work they like. This provides a level of interconnectivity not available on centralized and profit-centered platforms like YouTube.


Increasing user freedom and better monetization options for content creators will certainly drive many out of the YouTube world and into distributed platforms. However, whether Blockchain technology will change the online video streaming world or not, the value of the decentralized system should be clear. Both creators and users will find new and improving ways to access and share content.

World Bank President: Everyone Is Excited About Blockchain, Not Bitcoin


The president of the World Bank, Jim Yong Kim, was bullish about Blockchaintechnology when he spoke with CNBC during an interview. However, while expressing his positive views of the technology, he was quick to point out that there are risks when it comes to Blockchain technology derivatives like Bitcoin. When asked if the Blockchain based currencies were viable, he said:

"Blockchain technology is something that everyone is excited about, but we have to remember that Bitcoin is one of the very few instances [of Blockchain’s use in currency]. And the other times when Blockchain was used they were basically Ponzi schemes, so it’s very important that if we go forward with it, we're sure that it’s not going to be used to exploit.”
The World Bank functions as a lending house for national governments in order to provide needed capital. The institution has already been considering Blockchain technology solutions for some time, particularly in areas of financial transparency.


As the interview progressed, Kim’s views on Bitcoin became more clear, as he compared it with Chinese giant Alibaba, in terms of the speed and accuracy of transactions. He commented that with Alibaba, a transaction of $160,000 takes just ‘three seconds’ and that the company was able to assess the creditworthiness of the transaction in that amount of time. The implication being that Bitcoin is unnecessary when legacy models can do similar things.

Delaware Judge Throws Out Case Against Blockchain-Based Payment Network Ripple


In an apparent victory for the Blockchain-based payment network Ripple, a Delaware judge ruled in their favor regarding the recent lawsuit over R3 consortium’s wish to force the company to make good on a contract to buy a huge volume of XRP. The news broke via Ripple’s Twitter account:



R3, the ‘Blockchain-inspired’ startup servicing banks and financial institutions, maintains that Ripple Labs has violated a prior purchase agreement for XRP tokens between the two companies.

Califonia next
Brad Garlinghouse, Ripple’s CEO, started the Twitter feud, indicating that the judge in the Delaware lawsuit had ruled to ‘throw out’ the case. However, after further information came to light, the judge had issued a verbal ruling regarding Delaware’s jurisdiction over the matter. The lawsuit will proceed, however, in California and New York.


The case, according to others, will continue in California and New York. R3 is suing Ripple for specific performance of an option agreement in which Ripple agreed to sell up to five bln XRPs for a price of $.0085. Ripple has countersued, claiming that R3 reneged on a number of contractual promises, and is simply acting in a spirit of opportunism, after the cryptocurrency soared more than 30 times over.
