Bitcoin Warning As Serious Security Vulnerabilities Uncovered

Bitcoin developers have been trying to make the world’s most popular cryptocurrency more useful for payments, with the somewhat controversial Lightning Network one of the most popular projects.

However, serious security vulnerabilities have this week been discovered on the bitcoin Lightning Network, which could result in users losing their funds if nodes are not upgraded.

“Security issues have been found in various Lightning projects which could cause loss of funds,” wrote software developer, Rusty Russell, who authored the majority part of bitcoin’s Lightning Network protocol specification, in a post shared via a Lightning Network mailing list. “Full details will be released in four weeks, please upgrade well before then.”

The specifics of the vulnerability will be disclosed on 27 September, a common software security practise to both prevent bug exploitation and give developers time to patch problems.

The vulnerability appears to be related to the lightning-ready bitcoin wallet Eclair, which Russell also advised users to update.

The Lightning Network, first proposed by Thaddeus Dryja and Joseph Poon in a 2015 white paper, creates a layer on top of the bitcoin blockchain, where transactions can be passed back and forth before being added to the underlying blockchain.

This should mean bitcoin transaction speeds are increased while costs are significantly reduced.

There are now a few different Lightning-ready wallets available, as well as companies that are able to process them on behalf of merchants.

However, low user numbers mean bitcoin lightning nodes currently lose money when they process transactions, according to recent reports.

When sending a Lightning payment, two parties deposit the funds at one bitcoin address, a so-called channel, in which they can exchange funds a limitless number of times.

This maintains bitcoin’s security but means small, regular payments don’t need to be added to the underlying blockchain until the channel is closed.

Questions have been raised about what Lightning Network adoption will mean for the bitcoin price, with much of the price dependent on transaction fees picked up by miners.

Most are though confident that with increased bitcoin adoption the price will continue to rise.

The Winklevoss Twins Made A Serious Wall Street Bitcoin Warning

The Winklevoss twins of Facebook-founding fame have long been strong advocates for bitcoin and cryptocurrencies, buying up huge amounts of bitcoin and founding the U.S. Gemini crypto exchange.

The bitcoin price, now back above $10,000 per bitcoin after dipping under the psychological mark earlier this month, has climbed around 200% so far this year, emboldening bitcoin bulls who had feared last year’s bear market could drag on through 2019.

Now, the Winklevoss twins have warned Wall Street banks have been “asleep at the wheel” on bitcoin and cryptocurrencies—something that’s helped bitcoin retail investors.

“Unlike the internet, which you couldn’t buy a piece of, you can actually buy a piece of this new internet of money,” Tyler and Cameron Winklevoss told CNN.

“It’s still a retail-driven market, from day one. And a lot of people have done really well. Wall Street has been asleep at the wheel,” the twins warned.

Bitcoin’s epic 2017 bull run, which saw the bitcoin price soar from under $1,000 per bitcoin at the beginning of the year to almost $20,000 in December, was largely thought to be due to Wall Street and institutional investment could be poised to flow into bitcoin and crypto.

When this investment failed to firmly materialise, the bitcoin price crashed to around $3,000 per bitcoin last year, only to rebound in 2019 as a result of technology companies taking an interest in bitcoin and crypto.

“We had to invest because we were afraid of missing out, we couldn’t miss out on this future,” the twins added.

Meanwhile, Tyler and Cameron Winklevoss earlier said they are open to partnering with Facebook chief executive Mark Zuckerberg on the social media giant’s libra cryptocurrency project after it was revealed they have been in talks about joining the Libra Association.

The newly-created, independent governance consortium for Facebook’s planned token currently counts 28 founding members but is expected to swell to around 100 by the time of libra’s launch next year.

Blow To Bitcoin As Top Accountants Make Serious Facebook Warning

bitcoin, bitcoin price, Facebook, libra, image

Bitcoin and cryptocurrencies have been largely ignored by the world’s regulators over the last ten years, with only some small attempts to protect investors from wild bitcoin price swings and dodgy crypto exchanges.

The bitcoin price, up some 200% so far this year, has somewhat recovered after a terrible 2018 largely due to interest in bitcoin and cryptocurrencies from some of the world’s biggest tech companies, including social media giant Facebook which unveiled its planned libra cryptocurrency project last month and is scheduled for release some time in 2020—if the sandal-hit company can convince regulators of its merits.

Now, forensic accountancy firm BTVK has warned the bitcoin and crypto “wild west” could be coming to an end, with global regulators closing in on bitcoin and cryptocurrency exchanges as a result of the spotlight brought by Facebook’s libra project.

“Laws are in development as we speak,” Alex Hodgson, senior consultant at BTVK, told the Telegraph newspaper following the release of its report into bitcoin and cryptocurrencies. “Facebook has well-publicized issues in the past, and in response to that [regulators] are going above and beyond.”

“If cryptocurrency markets were like the ‘wild west’ in their early years, that period may be coming to a close as lawmakers look to toughen up the way in which markets are policed,” the report authors wrote. “In the meantime, it would be wrong to assume that investigators are powerless in the world of virtual currencies. They have many tools, old and new, at their disposal which mean that cryptocurrency markets should not be seen as a safe hiding place.”

Facebook is still reeling from a data-sharing scandal that saw many of its most senior executives hauled before governments around the world to answer questions on Facebook’s use of data and its work with third parties, such as Cambridge Analytica.

Earlier this month, U.S. president Donald Trump sent the bitcoin and cryptocurrency industry for a loop when he tweeted his opposition to bitcoin, cryptocurrencies, and Facebook’s libra, suggesting they are all “unregulated crypto assets” that can “facilitate unlawful behavior, including drug trade and other illegal activity.”

Following his comments, other senior U.S. officials echoed his comments, while U.S. senators called Facebook’s libra plans “unacceptable.”

Elsewhere, former International Monetary Fund managing director Christine Lagarde, who is set to replace Mario Draghi as president of the European Central Bank (ECB), earlier this year warned that bitcoin and cryptocurrencies are “shaking the system”—something that could signal a change in the ECB’s approach to bitcoin and crypto.

The bitcoin price has rallied hard this year but global regulators are “closing in.”

In the U.K. bitcoin and cryptocurrencies were placed under the oversight of the country’s banking regulator in January with it expected to issue final guidance sometime over the next couple of months.

Meanwhile, a government panel in India has recommended a ban on all “cryptocurrencies created by non-sovereigns” due to “serious concern [there is a] mushrooming of cryptocurrencies almost invariably issued abroad and numerous people in India investing in these cryptocurrencies.”

The report out of India does support the possibility of a state-issued digital currency in India, however.

Tim Draper Believes Bitcoin Will Grab 5% of the Earth’s Market Share

While Elon Musk and Jeff Bezos are focused on Mars, billionaire venture capitalist Tim Draper has his feet firmly planted on the ground. Draper might appear to have his head stuck in the clouds with a lofty $250,000 bitcoin price prediction. But from what he tells Fox Business, the early bitcoin investor isn’t stargazing:

“I’m a believer that in four years, something like that, bitcoin will be about a 5% market share of the earth.”

Draper’s Bitcoin War Chest is a Cool $189 Million

He pointed to bitcoin’s best features such as decentralization, transparency, and simply being a better currency than fiat. Draper was an early bitcoin investor, having purchased 30,000 BTC when the price was hovering at $632 per coin. He points out that the investment is worth 10x that amount today, and he’s got no doubt that it’s going much higher.

Draper envisions a future in which bitcoin further disrupts the venture capital business model.

“I eventually want to have a fund where I take in bitcoin and I fund everybody in bitcoin and they pay their employees and suppliers in bitcoin. And then I pay my investors in bitcoin. Because I would then require no acounting, no legal, no bookeeeping, no custody. It would all be done.”

Considering that transactions would be recorded on the blockchain, all relevant participants would be able to see everything. Tim is a big fan of bitcoin but he keeps an open mind about other cryptocurrencies, too. Though he does expect that the number of coins will be whittled down to only the best projects.

Tim Draper on Facebook

Everyone knows Facebook is pursuing a $1 billion fund for its new stablecoin, and Draper has been linked to discussions with the company about the initiative. Incidentally, the gloves came off on one of Facebook’s founding members earlier this week, with Chris Hughes calling for the breakup of Mark Zuckerberg’s company. Draper isn’t buying into it.

“If the shareholders will benefit somehow by a breakup, then sure go ahead and do it. But the idea that he has all this centralized power…I think he’s just building a business and it’s a great business. And there are plenty of competitors to him out there. And I’m very pleased that he’s done so well.”

If his tone is any indication, perhaps we will be hearing about a VC investment into Zuckerberg’s new blockchain project.

Meanwhile, the bitcoin price is currently hovering at $6,379. It’s a far cry from Tim Draper’s $250,000 target but if he’s right and it captures 5% of the earth’s market share, the moon will seem a lot closer than it does today.
