Bitcoin Gold, Verge, and Monaco have been hacked in a rare way this week - 51 percent of attacks - and hackers have successfully hacked nearly 20 million dollars. from the Bitcoin Gold ledger.
According to the motherboard, most virtual network professionals are less focused on attacks by 51 percent, making the concept less well-known. In the past, such attacks have been less common and have caused only minor damage (as in 2016, two attacks have occurred and cost a few thousand dollars), in part because of the amount of money Limited time. As for currencies that have become as commonplace as Bitcoin, 51% of attacks will be more difficult to implement.
The latest episode of the HBO-produced Silicon Valley TV series mentioned a 51% attack on the e-cryptic numbers the characters launched. And just days later, such attacks have taken place in real life.
A 51% attack is only successful when someone holds in excess of the sales (51% or more) of the capacity of a blockchain network. This control allows individuals or groups of people to start accounting books based on a particular crypto.
Thanks to this extensive network of controllers, the manipulator can conduct electronic trading (or withdrawal) on the ledger, the official ledger, and then send it to the individual ledger. Other computers in the network are still accepted as real money.
At present, although the virtual money is not spent, the attackers still benefit from the transaction process, especially fraudulent, such as double use of any currency controlled. OK. While gaining control of the network, an attacker can still ensure that new money flows into it.
The perpetrators have not yet been identified, and the government has not shown any moves.
In the future, small-scale virtual-scale blockchain applications will likely have to protect themselves by increasing the transaction capacity. And while it is not possible to completely prevent 51% attacks, it is necessary to create more servers, which make hackers have to invest heavily in computer systems to perform attacks. Targeted on large virtual money networks.
