The Polygon crew promised an evidence and right here it’s. A couple of weeks in the past, the Ethereum Layer 2 community hard-forked their blockchain, seemingly with out clarification. As traditional, NewsBTC bought to the underside of the case and introduced the entire out there info. The one piece lacking was a promised official report from Polygon’s consultants. Is that this it?

Earlier than we get into it, let’s keep in mind Polygon’s co-founder Mihailo Bjelic’s clarification as reported by us:
“We’re making an effort to enhance safety practices throughout all Polygon tasks,” Bjelic tweeted. “As part of this effort, we’re working with a number of safety researcher teams, whitehat hackers and so forth. Certainly one of these companions found a vulnerability in one of many not too long ago verified contracts. We instantly launched a repair and coordinated the improve with validators/full node operators. No funds had been misplaced. The community is secure.”
It’s essential to keep in mind that the crypto ecosystem was involved with the way in which that they managed to do all this. It appeared centralized. Nonetheless, the co-founder assured everybody that “The community is run by validators and full node operators, and now we have no management over any of those teams. We simply did our greatest to speak and clarify the significance of this improve, however finally it was as much as them to resolve whether or not they’ll do it or not.”
Nonetheless, this was Polygon node operator Mikko Ohtamaa’s additional grievance:
“Subsequent time it occurs are you able to not less than announce a crucial replace to all Polygon node operators. Now this appears tremendous unprofessional and complicated for the neighborhood. It was not talked about or pinned down in any main channels or publications.”
And that’s the story thus far.
What Did The Polygon Specialists Say?
Contemplating the notorious Poly Community exploit was merely in August this 12 months, it’s good to listen to Polygon is working onerous in securing their entire operation. They’ve ”been investing vital effort and assets into creating an ecosystem of safety professional companions, with the purpose of enhancing the safety and robustness of all Polygon options and merchandise.” With that in thoughts, that is the corporate’s model of what occurred:
“Lately, a bunch of whitehat hackers on the bug bounty platform Immunefi disclosed a vulnerability within the Polygon PoS genesis contract. The Polygon core crew engaged with the group and Immunefi’s professional crew and instantly launched a repair. The validator and full node communities had been notified, they usually rallied behind the core devs to improve the community. The improve was executed inside 24 hours, at block #22156660, on Dec. 5.”
To date, so good. This rhymes with Bjelic’s clarification and provides the neighborhood extra particulars. Nonetheless, we all know that they barely notified the validators and node operators. They don’t even need to lie about it, as a result of they do have an incredible motive as to why they ran the entire operation in stealth mode.
“Contemplating the character of this improve, it needed to be executed with out disclosing the precise vulnerability and with out attracting an excessive amount of consideration. We’re nonetheless finalizing our vulnerability disclosure coverage and procedures, and for now we are attempting to comply with the “silent patches” coverage launched and utilized by the Geth crew.”
In keeping with Ohtamaa, “there are a number of open supply tasks on the market” which have accomplished comparable operations in a simpler method. And that is likely to be true, nevertheless it doesn’t take from the truth that Polygon’s actions had been justified.

Bear in mind, one of many early criticism was that they forked the Polygon blockchain “to a totally closed-source genesis.” Right here, the official supply assures that “contracts and node implementations stay totally open supply.” Good. Is there one thing else they need to inform us?
“We’re nonetheless engaged on closing the ultimate proceedings with Immunefi and the whitehat hacker group, primarily by way of their rewards and a number of rounds of critiques of the fastened vulnerability. We are going to submit an in depth postmortem as soon as this course of is completed, probably by the top of subsequent week.”
The crew will publish one more submit with much more particulars for the technically oriented individuals. That’s above our pay grade. Keep tuned to Polygon’s weblog if you happen to’re .
