Vertcoin suffers its second 51 percent attack for the year and the latest attack occurred exactly one year since the last one as we reported in the previous altcoin news.
Reports of a 51% attack on the altcoin known as Vertcoin (VTC) has surged the internet in the last hours. The attack supposedly happened on the 1st of December 2019 at 15:19 UTC, when around 603 blocks were removed from the altcoin’s main blockchain. At the same moment, the perpetrators swapped them with 553 attacker blocks.
We are talking about 5 recorded transactions, according to some reports, that included double-spending, while the hacker managed to ‘earn’ approximately 13825 Vertcoin coins from block rewards, which is $3,211 or about 0.44 Bitcoin. One of the interesting things about the attack is that it happened exactly a year after the previous attack, as reported by DC Forecast in early December 2018.
In early December of 2018, reports started to come out that Vertcoin (VTC) suffered a 51% attack, when the project had 22 deep chain reorganizations, with 15 of them supposedly included double-spending of VTC. After the last’s year attack it was estimated that the perpetrators had stolen around $100,000, with the largest reorganization, went 300 blocks deep, according to Medium report by mark Nesbitt.
Github user known under the pseudonym metalicjames, who is the lead maintainer of Vertcoin, James Lovejoy, reported that Vertacoin was attacked once again. According to the report, the altcoin stoped using the PoW algorithm after the last attack and switched to Lyra2Rev3. While there was a belief by the developers that the project was safer for them, one of the miners noticed an unusual upswing in hashrate rental prices on November 30th, 2019.
Since Vertcoin has the most trafficked exchange by volume on Bittrex, the exchange was counseled to close its wallet to the coin since the happening of the incident. The exchange reacted by making the withdrawals impossible as soon as they received proof that Vertcoin suffers its second attack.
The real target of the attack could have been Bittrex, while Lovejoy outlines that the double-spend portion attack was aborted before the exchange disabled their wallet. In other words, PoC sabotage seems like the most convincing explanation for now.
Markets Fight For Support While Cosmos Outperforms Again
BitMEX Faces $300 Million Lawsuit Over Lost Equity
“Through this action, Plaintiffs seek damages representing the value of their equity interest in BitMEX, which is conservatively estimated to exceed $50,000,000, together with punitive damages of $250,000,000. Plaintiffs also seek injunctive relief and other remedies, together with their attorneys’ fees and costs.”This move is definitely a headache and as BitMEX faces a new lawsuit, it is something that is piling up in the negative news as of recently. According to reports from earlier, the exchange has seen its popularity enduring despite a major data leak in November. Bitcoin news outlets showed that executives at the exchange appear a little concerned by the blunder which saw a lot of email addresses sent out to other users.However, what still remains good is business - and daily trade volumes for the Bitcoin (BTC) derivatives are unchanged and currently at $1.6 billion. From this point, BitMEX is solid and remains one of the top exchanges in the world.
Circle Lays Off 10 More Employees, Rejects Connection To CEO Leaving
"None of this is related to Sean transitioning out of the co-CEO role. Sean will continue to serve on Circle's board.”As a reminder, Neville launched Circle with Jeremy Allaire back in 2013. As Circle lays off 10 employees now but has been strong over the years. We can see that they directed many of the changes in the industry in the recent years, including a pivot away from Bitcoin (BTC) as well as the acquisition of the cryptocurrency exchange Poloniex back in 2018.Last month, two former executives at Circle, Daniel Matuszewski and Julien Collard-Seguin along with a third partner founded the proprietary crypto trading firm CMS Holdings. This firm plans to invest 30% of its capital in the most liquid cryptocurrencies such as Bitcoin (BTC), Ether (ETH) and around 40% to 50% into less-traded digital assets.Matuszewski, who left the company in August, admitted that he would not have started a similar firm a couple of years ago because of risk concerns and explained:
“There was always a non-zero chance that bitcoin would gap down, die, and never come back. [...] It’s a lot safer now, in that it’s probably not going to disappear.”
