Bitcoin Cash [BCH] – Consensus vulnerability revealed by Cory Fields

Earlier today, in a Medium blog post, Cory Fields, a Bitcoin Developer from MIT Media Labs revealed his experience about discovering a critical Bitcoin Cash [BCH] vulnerability that could mean the end of BCH. In the past few hours, the post has spread like wildfire across all social medium platforms stirring up questions about responsible disclosure in open source projects. Cory had initially discovered the vulnerability in April 2018. He said: “On April 25, 2018, I anonymously and privately disclosed a critical vulnerability in Bitcoin Cash, one of the world’s most valuable cryptocurrencies — not to be confused with Bitcoin.” He further stated: “A successful exploit of this vulnerability could have been so disruptive that transacting Bitcoin Cash safely would no longer be possible, completely undermining the utility [and thus the value] of the currency itself.” However, the vulnerability that Fields discovered was successfully fixed and resulted in a zero impact on the cryptocurrency. The incident was publicly disclosed on May 7, 2018. Fields also clarified that the aforementioned vulnerability which has now been fixed had only posed a threat to Bitcoin Cash and not Bitcoin. The vulnerability referred by Fields as “SIGHASH_BUG” had the potential to result in a chain split which simply means that the bug had the ability to split the currency into two incompatible currencies, making it completely impossible for users to make transactions. Fields discovered the bug while rummaging through Bitcoin ABC’s change-logs. He stated: “After seeing the minimal review the changes had undergone and the large number of lines changed, I thought it reasonably likely that a bug might have slipped in, and so I went looking. It took less than 10 minutes to find SIGHASH_BUG.” He further stated that the revelation was not to demean Bitcoin Cash but was an eye-opener to all the companies and developers who are not well equipped for the situation. He also believes that a lot of work remains in order to reach a mature level of engineering that cryptocurrencies require. He concludes his post by appealing developers to come together and work as a community to re-think all the procedures and policies that are in place and to put available tools to best use and learn from situations like the above to be better prepared for the future. Vinny Lingham, the CEO of CivicKey tweeted: “This is a good read for everyone working in crypto. Responsible and ethical behavior by everyone in the community, regardless of ideological beliefs, should be applauded.” Vitalik Buterin, the Co-founder of Ethereum retweeted Vinny’s post and said: “Questions remain as to how this revelation will be taken forward and the countermeasures that the cryptocurrency world will adapt, to reduce incidents such as these.” The post Bitcoin Cash [BCH] – Consensus vulnerability revealed by Cory Fields appeared first on AMBCrypto.

Binance Coin (BNB) Falters Pushing Bitcoin Dominance Index to 2019 High

Binance Coin (BNB), the best performing cryptocurrency in 2019, is having hard times maintaining its recent gains despite major developments. Meanwhile, the Bitcoin dominance index has hit its highest so far in 2019.  Binance Coin Struggles As Bitcoinist reported last week, Binance Coin (BNB) 00 is amongst the best performing cryptocurrencies in 2019 so far. Year-to-date, the altcoin has gained around 260 percent. Moreover, a few days ago, BNB became the first to surpass its all-time high value of January 2018. On a shorter term, however, the cryptocurrency doesn’t seem to be able to maintain its gains. Since its price surged towards its newly-found ATH on April 20th, BNB has pulled back, experiencing a notable decrease of around 11 percent against the USD. Against Bitcoin, BNB is down even more with a 16 percent decline. ‘Binance Effect’ Fizzles… For Now Controversially, the sudden pull-back comes at times when there’s a lot going on for Binance and BNB. Earlier in this month, Binance launched the mainnet for their decentralized exchange Binance Chain. Touted as a “new chapter” in the history of the company, the event also set the stage for an important development for the currently existing ERC20-based BNB coins – their swap to Binance Chain. Moreover, Bitcoinist reported that every project which migrates to Binance Chain sees its token’s price skyrocket on the news. Since our last report, two more projects have migrated to Binance Chain, namely Gifto (GTO), and the Blockmason Credit Protocol (BCPT). Their prices, unsurprisingly, marked notable increases following the move. On another note, Binance Launchpad – the Initial Exchange Offering (IEO) structure of the cryptocurrency exchange, is having its fourth sale today with a brand new lottery system in place. According to the official website, the ticket claim process is already in progress. Ironically, Binance Coin seems to be the only cryptocurrency that fails to capitalize on the so-called “Binance Effect.” …Nor Does BTC Price Pump Another thing to consider is Bitcoin’s price performance throughout the same period BNB has been declining. Since April 22nd, BTC has marked yet another notable leg up, jumping from around $5,300 to $5,630 – an increase of about 6.3 percent. Bitcoin price 00 has experienced a slight pullback since its recent peak, losing about 1.5 percent on the day. However, looking at the overall cryptocurrency market reveals that BTC is actually holding relatively strong compared to other altcoins, most of which are bleeding notably. In result, the Bitcoin Dominance Index, which measures Bitcoin’s relative market share by capitalization, has risen to 54.7 percent, the highest in 2019 so far. What do you think of the recent drop in the price of Binance Coin? Don’t hesitate to let us know in the comments below!

Coinspeaker Breaking: NASDAQ is Testing Trading of a Bitcoin-based ProductIt’s great news for Bitcoin (BTC) enthusiasts and the crypto community as Nasdaq is possibly testing the trading of a Bitcoin-based product.

I bought one BTC through my TDAmeritrade account! According to the chart it started trading April 10, 2019!! Other digital assets are soon to follow!! 🚀🚀🚀 pic.twitter.com/1VgE1Whoa4— Cryptopolis (@cryptopolis_x) April 22, 2019As we can see, Bitcoin (BTC) was trading against the U.S. Dollar under the ‘CXERX’ ticker symbol. However, Cryptopolis laters spoke with the support team of TD Ameritrade to clarify this matter. It turned out that this was just a test on Paper Trading platform meaning that you can just simulate a Bitcoin (BTC) buy, but not actually purchase it.However, the support denied giving additional details regarding this matter. In another tweet, Cryptopolis wrote:“UPDATE: According to TDAmeritrade support – it’s not a real trade in my account – it appears they are testing only using their Paper Trading platform. Support said “I’m not able to speak on it” -They did not know what CXERX is. Strange… But something is going on for sure!”Nasdaq’s Bitcoin Trading to Trigger Next Bull RunUndoubtedly, the availability of Bitcoin trading on the Nasdaq platform could trigger the next bull-run in the crypto market. It would be huge news for the overall crypto community as this could lead to a flood of institutional money flowing into the crypto market.Since long, Nasdaq has been to step in the crypto market through one or the other route. Nasdaq already provides several crypto exchanges with real-time information on two cryptocurrency indices – Bitcoin and Ethereum. If the world’s second-largest stock exchange allows BTC trading, it will open the floodgates for huge investor participation.Furthermore, Nasdaq is most likely to launch its Bitcoin futures contracts along with VanEck in the first half of 2018. A Bloomberg report released in November 2018 read:“Nasdaq has been working to satisfy the concerns of the U.S.’s main swaps regulator, the Commodity Futures Trading Commission, before launching the contracts, the people said. The New York exchange operator, which was first reported to be eyeing Bitcoin futures last year, wants to allow trading in the first quarter of 2019, one of the people said.”Nasdaq is most likely to be accompanied by another big player – Bakkt – who is planning for Bitcoin futures launch ahead this year. The year 2019 is likely to bring some of the most interesting developments in the crypto market.Since the beginning of April 2019, Bitcoin and the overall crypto market has created a fresh new hope after months of massive crypto winter. Bitcoin price has surged by nearly 30% in the last three weeks as it sets its new target for $6000. Similarly, the overall market has added $40 billion since April 1, as altcoins majorly participate in this month’s bull run.Breaking: NASDAQ is Testing Trading of a Bitcoin-based Product

According to Mr. Hoskinson, thanks to this partnership the Ethiopian authorities, the government will allow its citizens to use ADA to make payments as if it were fiat.
