On Friday, February 9, 2018, Italian cryptocurrency exchange BitGrail in response to the news. The team started with:
From our own preliminary investigation, no double spending was detected on the ledger and we have no reason to believe the loss was due to an issue in the Nano protocol. The problems appear to be related to BitGrail’s software. We had no knowledge of BitGrail’s insolvency prior to February 8th.
It concluded with this accusation:
We now have sufficient reason to believe that Firano has been misleading the Nano Core Team and the community regarding the solvency of the BitGrail exchange for a significant period of time.
Reactions from Firano were expectedly harsh, including one tweet where he stated:
In the wake of the unfounded accusations made against me by the dev team and of the dissemination of private conversations that compromise police investigations, BitGrail s.r.l. is forced to contact the police in order to protect its rights and users.
It should be noted that the Nano team relayed through its Medium post that they would “not be responding to individual posts or accusations by Firano regarding this situation.”
As BitGrail was one of the few exchanges that had been accepting Nano, the coin is now facing trading volume declines, down from the $50 million reported by the Wall Street Journal on February 10, 2018.
Nano also linked a pdf of a private conversation between Firano and Nano core team members Shapiro and Colin LeMahieu. The chat shows Firano’s insistence that the loss of Nano was due to an issue with corrupted time/date stamps of the errant transactions and suggested the fault lay with Nano as non-Nano wallets remained intact. Shapiro and LeMahieu disputed this claim. Firano also asked if the stolen coins could be forked in order to recover the “stolen” Nano from the burned address. The dev team refused to acknowledge a fork as a possible solution.
Firano stated in the chat that he first noticed the bug eight hours prior to the conversation with Shapiro and LeMahieu. Shapiro challenged Firano’s timeline, asking, “If withdrawals have been closed for the last month, how did you not notice this? Someone with[sic] allegedly withdrawing for weeks according to you via this ‘hack.’”
Social Media Reacts
Regardless of fault, the turmoil caused by the loss of $170 million worth of Nano on the BitGrail exchange has left both the exchange and the dev team faced with accusations, angry customers and little recourse for those affected.
