Verge to Implement Hard Fork Due to 51% Attack

Network hash of Verge get under control of unknown miner
05 April 2018   483

Verge coin fell the victim of 51% attack. Unknown miner has gained control over the network hash and can now change transactions, questioning the integrity of the whole blockchain. The attacker stole about 250,000 Verge coins and eventually forced the project team to prepare a hard fork.

There's currently a >51% attack going on on XVG which exploits a bug in retargeting in the XVG code. Due to several bugs in the XVG code, you can exploit this feature by mining blocks with a spoofed timestamp. When you submit a mined block (as a malicious miner or pool) you simply set a false timestamp to this block one hour ago and XVG will then “think” the last block mined on that algo was one hour ago.

The attacker managed to miner a lot of blocks with seconds between them. This was done using the scrypt algorithm (which was considered impossible). The attack was less intense in three hours, but by that time the attacker had confirmed hundreds of blocks, which led to the need to roll back the blockchain to compensate for the damage.

Developers published on Github a hotfix for a snapshot of the project to temporarily fix the problem, which he managed to do only with the second attempt. In order to remedy the situation once and for all, the hardfork will be initiated.

The US Securities and Exchange Commission (SEC) announced the beginning of a formal process for considering the application for the creation of bitcoin-ETF from the New York companies VanEck and SolidX. Nevertheless, the agency appealed to the community for more information. This is stated in the document published on the SEC website.

Institution of such proceedings is appropriate at this time in view of the legal and policy issues raised by the proposed rule change. Institution of proceedings does not indicate that the Commission has reached any conclusions with respect to any of the issues involved. Rather, as described below, the Commission seeks and encourages interested persons to provide comments on the proposed rule change.

At the moment, the SEC received about 1,400 comments.

According to the document, the Chicago Board Options Exchange (CBOE) has signed an agreement on the exchange of data on bitcoin transactions, trading and the state of the market with the cryptocurrency trading platform with Gemini.

The agency asked commentators to clarify the position of Gemini in the digital currency market and assess the likelihood of increased volatility at this site in connection with possible trades of bitcoin-ETF.

So, before September 30, the department had to decide on whether to approve, deny or initiate the proceedings. The SEC chose the latter, which is likely to delay the process until the next year.
