Poloniex exchange rolled back the history of operations due to a bug
Cryptocurrency exchange Poloniex in its Twitter announced the start and subsequent completion of technical work that required a complete stop of trading. As the company explained, the problem was related to errors in the processing of user requests..
“Today at 17:53 UTC, we identified a bug that caused incorrect execution of orders in a short time,” the exchange writes. “Our automated balance checking system found an error and put the site into maintenance mode. We identified a bug and carried out work to fix it “.
“To avoid any miscalculation due to a bug,” Poloniex decided to roll back trading history within 12 minutes on February 10th from 20:53 GMT to 21:05 GMT. All orders placed or executed at this time were removed from the system. In addition, withdrawal requests were canceled and the ability to re-deposit funds was temporarily limited..
By the time of publication, all Poloniex features have been restored. What exactly was the problem and to what volume of transactions it covered, the company does not specify.
In late December, some Poloniex users received emails asking them to change their account passwords due to an alleged data breach. As the company later explained, “there was no data leak from Poloniex, and our actions became a quick response to an external threat.”.
