Polygon ’s Side Of The Story: Hard-Fork Resolved A “Critical Vulnerability”

The Polygon group 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 typical, NewsBTC obtained to the underside of the case and offered the entire obtainable info. The one piece lacking was a promised official report from Polygon’s specialists. Is that this it? Apparently so.

Earlier than we get into it, let’s bear 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. Considered 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 steady.” 

It’s necessary 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 we have now 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 determine whether or not they’ll do it or not.”

Nonetheless, this was Polygon node operator Mikko Ohtamaa’s additional criticism:

“Subsequent time it occurs are you able to no less than announce a essential replace to all Polygon node operators. Now this seems to be 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 to date.

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 complete operation. They’ve ”been investing vital effort and sources into creating an ecosystem of safety professional companions, with the aim of bettering the safety and robustness of all Polygon options and merchandise.” With that in thoughts, that is the corporate’s model of what occurred:

“Just lately, a bunch of whitehat hackers on the bug bounty platform Immunefi disclosed a vulnerability within the Polygon PoS genesis contract. The Polygon core group engaged with the group and Immunefi’s professional group 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.”

Thus far, 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 must lie about it, as a result of they do have an excellent 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 try to observe the “silent patches” coverage launched and utilized by the Geth group.”

In accordance with Ohtamaa, “there are a number of open supply tasks on the market” which have finished related operations in a simpler method. And that is likely to be true, but it surely doesn’t take from the truth that Polygon’s actions had been justified.

The Aftermath

Ultimately, the essential replace labored out advantageous sufficient:

“The vulnerability was mounted and injury was mitigated, with there being no materials hurt to the protocol and its end-users. All Polygon contracts and node implementations stay absolutely open supply.”

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 absolutely open supply.” Good. Is there one thing else they wish to inform us?

“We’re nonetheless engaged on closing the ultimate proceedings with Immunefi and the whitehat hacker group, primarily when it comes to their rewards and a number of rounds of critiques of the mounted vulnerability. We’ll submit an in depth postmortem as soon as this course of is completed, probably by the top of subsequent week.”

The group 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 for those who’re .
