Using the bounty platform HackerOne, EOS developer Block.one launched a bug bounty program to improve the product on May 31, 2018, and Vranken took full advantage of it. At the time of writing, HackerOne shows that Vranken earned a total of $90,000, but he wrote on Twitter that the final number will be $120,000 once the tally updates.
EOS is still updating the hacker activity and has already thanked him, along with another hacker. The base amount for finding any bug in the software is currently $10,000. According to tech news website ZDNet, EOS team members were impressed by Vranken’s work and offered him a permanent job. However, it hasn’t been confirmed whether he accepted the role or not.
