Researchers were able to discover a vulnerability in different cryptocurrency networks. This is currently affecting $54 worth of Bitcoin (BTC), $14 worth of XRP and just 0.00002 ETH. The problem is related to a vulnerability in digital signatures that affect these different virtual currencies.

As per the researchers, the problem seems to be related to a faulty set-up in hardware, multi-sig or the possible generation of a not very random number.
One of the researchers, Joachim Breitner, explained:
“When you create a cryptographic signature using ECDSA (the elliptic curve digital signature algorithm), you need to come up with the nonce, a 256-bit random number. It is really important to use a different nonce every time, otherwise, it is easy for someone else to take your signatures and calculate your private key suing relatively simple math.”
According to Breitner, there are people monitoring blockchains for signatures that have these repeated nonces and try to extract the money from these keys.
The paper suggests that the attack would be very limited since it could only affect $54 worth of Bitcoin, $14 XRP and 0.00003 ETH. Additionally, this could be prevented using deterministic ECDSA nonce generation that is already implemented in Bitcoin and Ethereum libraries. Additionally, the flaws do not appear to be known since the funds were not yet stolen. However, it would require time, skills and ability to perform the attack, which could be used for another purpose.
If you are a recent Bitcoin user with a new wallet from a popular service, there is not much to worry about.
Bakkt Futures to Launch in the Current Quarter
Managing director and quant strategist at Fundstrat Global Advisors Sam Doctor suggested in a Twitter post published on July 19 that Bakkt’s Bitcoin (BTC) futures contracts will launch this quarter.
According to the post, which includes a summary of Fundstrat’s takeaways from the Bakkt Digital Asset Summit held on July 18, the firm’s futures will launch in the current quarter. The launch is set to follow tests announced last month, which are scheduled to start next week. The firm believes that the launch will be a catalyst to accelerate entry of traditional institutional investors. The post notes:
“THERE APPEARS TO BE A CRITICAL MASS OF ADOPTERS READY TO COME ON BOARD ON DAY 1 OF THE BAKKT LAUNCH, WITH THE SALES TEAM GAINING TRACTION AMONG BROKERS, MARKET MAKERS, PROP TRADING DESKS AND LIQUIDITY PROVIDERS.”
During the aforementioned event, Commodities Futures Trading Commission (CFTC) commissioner Dawn Stump apparently expressed that no current cryptocurrency could threaten financial stability and that the regulator sees a growing demand for Bitcoin futures from the public. Also during the summit, chief information officer at crypto investment firm Blocktower Ari Paul was reportedly confident that once a killer app or user interface makes cryptocurrency on-ramps safe, reliable and as easy to use as Paypal, retail adoption will be enormous.
According to the Fundstrat notes, Paul also said that institutions should not dismiss crypto assets, considering their low correlation with traditional assets and with compound annual growth rates of 200%-300%. He also said that inflation and confiscation resistance of cryptocurrencies are a key value proposition.
Pantera Capital CEO Dan Morehead, on the other hand, said that most tokens will fail and a handful of base protocols will survive, but with thousands of decentralized applications built on top of them.
As Cointelegraph reported in May, the Intercontinental Exchange is reportedly taking steps to ensure approval from the United States CFTC for Bakkt.
Bitcoin Price Slips 10% in 24 Hrs as Fed Raises Facebook Libra Concerns
Bitcoin Price Slips 10% in 24 Hrs as Fed Raises Facebook Libra Concerns
Bitcoin price (BTC) shed more than 10% on July 11 as markets appeared to react to criticism of Facebook’s Libra from a senior United States lawmaker.

Data from Coin360 sees the majority of cryptocurrencies firmly in the red Thursday, hours after Federal Reserve Chairman Jerome Powell said Facebook’s offering should not continue development.
Libra, which aims to act firstly as a cross-border payment method, allegedly buoyed Bitcoin throughout recent weeks, with commentators arguing its public profile was driving publicity and uptake of Bitcoin itself.
Powell’s demands, which follow similar words from representatives of the Senate House of Financial Services Committee, leant weight to that theory.
“Libra raises serious concerns regarding privacy, money laundering, consumer protection, financial stability,” he said during a speech before a congressional committee. “These are concerns that should be thoroughly and publicly addressed.”
“THESE ARE CONCERNS THAT SHOULD BE THOROUGHLY AND PUBLICLY ADDRESSED.”
At press time, BTC/USD traded down 10.4% at $11,530, having risen as high as $13,160 in recent days.

The drop places the pair still within its recent corridor between around $9,700 and $13,800, with volatility still in evidence across crypto markets.
Altcoins, meanwhile, delivered noticeably worse performance as Bitcoin price fell, with several assets in the top twenty by market cap shedding 15% or more.
Ether (ETH), the largest altcoin, lost a similar amount to Bitcoin, hitting $272 and firmly losing support at $300 once again.
