What’s new? Hacker Saurik discovered a vulnerability in Optimism, an Ethereum scaling solution. The hacker published a report and reported the bug to the developers, he received a reward of $2 million. This vulnerability could have caused major losses on the part of the platform.
What was the vulnerability? While reviewing the nano payment protocols, the hacker discovered a bug that allowed the withdrawal of “virtually unlimited” amounts of ETH. A similar bug was found in the Wormhole cross-chain and caused the network to lose $340 million.
What does the community say about this? The users began to argue about the amount of the reward. But everyone agreed that if a black hat hacker had been exploited the vulnerability, the damage to the protocol would have been enormous.
Large payments like this encourage users to report their “discoveries” rather than take advantage of the vulnerability. Such white hackers help companies save billions annually.
