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.

Bitcoin Has ‘No Intrinsic Value,’ As U.K. ‘Moves Towards’ Crypto Ban

Bitcoin and cryptocurrency regulation has been pushed into the limelight over recent weeks, thanks to social media giant Facebook’s high profile plans to launch its own potential rival to bitcoin sometime next year.

The bitcoin price, which had been climbing on rumors that big technology companies were taking an interest in bitcoin and cryptocurrencies, has plateaued at around $10,000 per bitcoin after a number of countries rebuffed Facebook’s plans, unveiled in June.

Now, the U.K.’s financial services watchdog has warned potential investors that bitcoin and cryptocurrencies have “no intrinsic value,” with some taking the caution as a signal the country could be moving towards a bitcoin ban.

“This is a small, complex and evolving market covering a broad range of activities,” said Christopher Woolard, executive director of strategy and competition at the U.K. Financial Conduct Authority (FCA), which oversees London’s huge banking industry.

“Today’s guidance will help clarify which crypto-asset activities fall inside our regulatory perimeter,” Woolard added, with the FCA warning: “Consumers should be cautious when investing in such crypto-assets and should ensure they understand and can bear the risks involved with assets that have no intrinsic value.”

The FCA branding bitcoin and cryptocurrencies as without “intrinsic value” is likely to rile many bitcoin believers who have long argued blockchain technology, which underpins bitcoin and most other cryptocurrencies, gives the digital tokens value.

“It is technically true that cryptocurrencies have no ‘intrinsic value’ when compared to share ownership in actual companies, however there are many examples where a marketplace bestows value on an intangible asset,” Jon Ostler, of comparison site Finder.com, told the U.K.’s Telegraph newspaper. “For example, the brand of ‘bitcoin’ itself has value and although its future place in society is still unclear, it is one of the most likely coins to stay the course.”

The warning from the U.K. comes shortly after U.S. president Donald Trump unleashed a scathing attack on bitcoin and cryptocurrencies, comments that were then echoed by other senior officials in his administration, including Treasury secretary Steven Mnuchin who branded bitcoin and cryptocurrencies a “national security issue.”

It’s thought that Trump’s attacks on bitcoin and crypto were in direct response to Facebook’s libra cryptocurrency project, which, if successful, could undermine the international dominance of the U.S. dollar.

“Although not a ban, [the U.K.’s FCA warning is] a move in that direction,” said Herbert Sim, head of business development from Broctagon Fintech Group. “This lack of enthusiasm is shared by several countries; the U.S. with its scrutiny of libra, and India, who are looking to implement a similar ban on cryptocurrencies which are not state regulated. These movements could end up coming back to bite. The international competition on cryptocurrencies is heating up and there are huge risks in being left behind.”

Meanwhile, the watchdog warned investing in what it called “unregulated crypto-assets” will not be covered by the Financial Services Compensation Scheme, which pays out if the investment collapses.

“It remains possible in the future that if an unregulated token is subject to common acceptance and usage in the U.K. then either the FCA or the Bank of England will reconsider this position in order to ensure that adequate consumer protection exists,” said Tim Dolan, partner at law firm Reed Smith.
