Copy-paste | Vertcoin has been attacked by 51%

Vertcoin had a 51% attack, its coins were spent twice, and 603 blocks were replaced by an attacker's transactions.

As Vertcoin lead maintainer James Lovejoy claims, there is strong evidence that this attack was carried out using a leased hash rate from Nicehash.
The attack was initially detected by checking the work sent from the servers in the Nicehash formation, which sent work for non-public blocks.

Below is a screenshot of the console outputNicehash mining software showing the performance of data for VTC 1253804, when at that time the height of the public VTC was 1253800.

As a result, hackers seem to have received a net loss of 0.06 BTC ($ 440) to 0.56 BTC ($ 4,100).
