In a Medium blog site article, Corey Fields disclosed that he was dependable for anonymously and privately informing Bitcoin ABC of the SIGHASH_BUG in Bitcoin Hard cash on April 25 this 12 months. In accordance to Fields, who will work for MIT Media Lab’s Electronic Forex Initiative, if the vulnerability had been efficiently exploited it would have resulted in building bitcoin funds transactions unsafe, hence undermining the fourth-major cryptocurrency by marketplace capitalization. As CCN described, the flaw was fastened early the pursuing thirty day period.
Bitcoin’s Biggest Risk
In the very same article, Fields warned that the best risk dealing with bitcoin is connected to software program development.
“I’m usually asked at conferences and workshops what I consider to be Bitcoin’s best obstacle in the future. My reply is generally the very same: keeping away from catastrophic software program bugs,” he wrote.
In accordance to Fields, the risk posed by software program bugs with regards to cryptocurrencies is underestimated and businesses in the place have to make sufficient preparations for these kinds of threats. As an illustration, Fields narrated the hoops and loops he had to bounce via before he could notify Bitcoin ABC of the vulnerability.

In accordance to Fields, it was also essential to continue to be anonymous for individual protection reasons just in case a malicious actor discovered the vulnerability and went on to exploit it before a correct could be rolled out. This would be problematic as suspicions could slide on Fields.
“Because I utilised my identify for the disclosure, really hard proof would exist that I had the awareness and suggests to attack the network. I would have no way to demonstrate that I was not the attacker. Then consider that, collectively, billions of bucks could have been missing as a consequence of this exploit. Men and women have been killed for substantially fewer,” wrote Fields.
At the time when Bitcoin ABC declared that the vulnerability had been fastened, it was disclosed that a reward would be specified to the then-anonymous tipster the moment they went general public. In his blog site article, Fields did not disclose whether he has claimed the reward.
