I'm a bit hesitant right now, if there's no one coming forward to report or at least find some bugs, then I doubt that there will be someone. I'm under the impression that at least one or two bugs with severities will be found by these white hackers.
Anyhow, let's continue to wait and see, and I do hope the Eth2.0 devs really did a good job and not totally relying to these bounty to test their system. They should do their own testing, just saying.
If there are no reports about the bug then it's either they are not yet attracting capable hackers or their developers are so good that they have created a bug-free platform, it's too early to tell until they announced that there is no bug in their platform and they can proceed in launching it, this is one of the news that adds credibility to Ethereum.
how much is thier reward ? i didnt visit the link yet and op didnt provide it on the first page .
maybe the amount is not reasonable to the hackers because we know hacking isnt an easy task unlike to a crypto exchange or banks that they are going to be motivated to hack because there are huge sums inside it waiting for them but the announcement is also new and many may hackers havent notice it yet . lets wait for several weeks or months before we judge them .
