Coinmetrics chief operating officer Antoine Le Calvez was one of the first to notice the reorg, sharing a screenshot on Twitter showing that at least 560,000 blocks had disappeared on Feb. 15.
As a result of this roll-back, any user who received or purchased XVG tokens since July 2020 may have lost their entire balance, with Deribit Insights’ researcher “Hasu” tweeting that “thousands of balances have simply evaporated.”
Despite the scale of the potential attack, Hasu believes it will be “pretty easy to counter,” advancing that “nodes will reject the attacker’s chain and restore the previous one.” Hasu stated the incident highlights the vulnerability of blockchains supported by GPU mining.
An unconfirmed screenshot shared by Twitter user Crypto_Michael showed XVG advisor AlexanDre stating the source is linked to some nodes who wanted to create a fork.
