Attackers managed to steal $23.5 million of three completely different cryptocurrencies from the decentralized trade Bancor. Though Bancor was in a position to mitigate the damages right down to $13.5 million, the hacker or hackers are nonetheless a future by which they could possibly be millionaires.

The hack, which was detected on Monday, kicked off quite a few debates reminiscent of whether or not Bancor is definitely a decentralized service. Bancor dubbed itself as a “decentralized liquidity community” and its protocol (pdf) makes use of good token contracts.

How the Bancor hack occurred

As for what truly occurred, Bancor said no consumer wallets had been compromised, however “a pockets used to improve some good contracts was compromised.” The attackers used the compromised pockets to steal $12.5 million of ether, $1 million of Pundi X, and $10 million of Bancor Community Tokens (BNT).

Making an attempt to make clear, Banor added that the 24,984 ETH, price roughly $12.5 million, “was stolen out of BNT’s connector steadiness (like a reserve). The remainder of the stolen tokens had been taken from good contracts that the breached pockets had entry to on the community.”

To know that clarification, Bancor defined that you will need to perceive how good tokens work.

“A Good Token like BNT has value discovery construct into the good contract. By sending the good contract ETH (basically shopping for BNT), new BNT tokens are issued and ETH is saved in a related steadiness. When BNT is distributed again to the good contract (basically promoting BNT), the BNT tokens are destroyed and a proportional quantity of ETH is faraway from the token’s related steadiness and despatched to the vendor,” it stated.

After Bancor realized the theft occurred, it frozen the $10 million in BNT.

“The power to freeze tokens was constructed into the Bancor Protocol for use in an excessive state of affairs to get well from a safety breach, permitting Bancor to successfully cease the thief from working away with the stolen tokens,” it stated.

Is Bancor’s declare that it’s decentralized correct?

However the potential to do this is precisely what kicked off a debate whether or not Bancor ought to declare to be really decentralized.

For instance, Charlie Lee, creator of Litecoin, tweeted, “An trade just isn’t decentralized if it could actually lose buyer funds OR if it could actually freeze buyer funds. Bancor can do BOTH. It’s a false sense of decentralization.”

Others, reminiscent of bitcoin developer and advisor Udi Wertheimer, regard Bancor’s potential to get well stolen cash as a backdoor.

With out utilizing the time period backdoor, but attempting to deal with the decentralization argument, Bancor tried to make clear that the flexibility to freeze stolen BNT was one of many security measures meant to guard its neighborhood and a part of a three-year pilot interval.

“We firmly consider that this potential is a preventative measure important to most tokens and crucial to guard the community and token holders in a state of emergency,” it stated.

Whereas unable to freeze the opposite stolen cryptocurrencies, such because the stolen ether (wallet), Bancor is working with “dozens of cryptocurrency exchanges to hint the stolen funds and make it harder for the thief to liquidate them.”

The corporate believes it can quickly reactivate the Bancor Community and appreciates the “wholesome debate on the steadiness between safety and decentralization that has ensued.”
