Class Action Lawsuit Seeks Court-Ordered Hard Fork of Nano/XRB

In a new twist in the BitGrail saga, Nano is being sued.

A class action lawsuit is seeking a court-ordered hard fork of a cryptocurrency – if the suit is successful, it will be unprecedented.


The cryptocurrency in question is called XRB, which comes from a blockchain called Nano. The lawsuit concerns $150 million worth of XRB tokens being stolen from Italian cryptocurrency exchange BitGrail in February 2018. BitGrail and Nano both blame each other for the hack.

As we reported at the time, the operator of BitGrail, Francesco “The Bomber” Firano, drew ire because his handling of the exchange leading up to the theft seemed suspicious, and his reaction in the aftermath of the heist left much to be desired.

The only currency stolen from the exchange was XRB. Evidence suggested that the money was stolen because of shortcomings in the exchange’s security systems. This was certainly the attitude taken by Nano, which contacted the authorities as soon as it was informed of the theft and published a statement distancing itself from BitGrail.

Bitgrail continues to blame the theft on a malfunction in Nano’s software.

Hard fork

Now, the thing that most angered users of the exchange was the fact that Firano made it clear that BitGrail would not be able to repay them because it simply didn’t have the money.

One solution would have been for Nano to undergo a hard fork. A hard fork is an upgrade of a blockchain, so called because the chain can be visualised as splitting into two paths. Users receive the new version of the cryptocurrency equal to the amount of the old version held at that moment, and the old version becomes unusable (if the fork is accepted – but that’s another story). By doing this, victims of the BitGrail hack would have had their funds restored.

Nano’s response to this request: “An option suggested by Firano was to modify the ledger in order to cover his losses – which is not possible, nor is it a direction we would ever pursue.”

Firano thus attempted to switch blame to Nano:

The exchange closed immediately after the hack but has since reopened with a less-than-promising plan to repay customers.

The twist

Users of BitGrail had been discussing a lawsuit against the exchange even before the hack because withdrawals had been suspended. Not only was this a violation of the exchange’s terms of service, they suspected that the exchange was looking to manipulate the price of XRB; at the time, the exchange handled about 75 percent of all XRB transactions, and the largest exchange in the world had recently announced that it would be listing XRB in the near future. They used Reddit to discuss a class action suit, planning to use a law firm called Silver Miller Law.

But in the end, it is Nano being sued… and by the very same law firm.


Basically, NANO knew of the issues being faced by BitGrail. The fact that it continued its association with a faulty exchange makes it at least partly complicit in the security failings. The law firm says in its press release:

“Silver Miller has commenced a new class action lawsuit on behalf of investors in NANO f/k/a RaiBlocks (XRB), alleging that NANO and key members of its core team violated federal securities laws and that, in their push to introduce XRB to a wide market of investors, recklessly directed investors to open accounts and place their assets with a little known, and severely troubled, Italian cryptocurrency exchange called BitGrail..”
