Mark Cuban points burn discover on offensive ENS area

02/03/2021

One-upping this crypto troll was no drawback for the crypto-savvy billionaire.

Somebody despatched Mark Cuban a profane Ethereum Title Service area just a few days in the past. After observant Twitter customers lately tracked down his ether tackle, it was solely a matter of time earlier than a wave of undesirable spam transactions made their manner into his account. That is, in spite of everything, the web. Right here there be monsters.

Whereas it isn’t fully clear what the presumed troll’s endgame was, the phrase was nonetheless offensive sufficient to lift some eyebrows at Cointelegraph, and we don’t intend to reprint it right here. Suffice to say, an honest particular person wouldn’t need to be generally known as the proprietor of this area, even when they weren’t a celeb billionaire.

We reached out to Mark Cuban to search out out, initially, if he knew something about its origin. Had he bought it himself? Was he even conscious he owned it? And most significantly, what had been his plans for the title going ahead?

He responded:

“Rattling. No, I do not personal [it]. I assume anybody can put an eth tackle to a website. I do not even know if it’s doable to alter it. Thanks for the heads up.”

Whereas Cuban has grow to be more and more concerned within the blockchain house of late, he’s nonetheless a relative newcomer to sure facets of the group. As such, his understanding of how Ethereum Title Service, or ENS, domains are acquired, managed, and transferred was considerably restricted initially.

ENS presents customers a decentralized manner to make use of human-readable phrases for his or her blockchain tackle as a substitute of an unwieldy alpha-numeric string. Vitalik Buterin, as an example, is understood to make the most of vitalik.eth for his tackle as a substitute of 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Simple peasy.

The issue with this service is that after you personal an ENS area, you possibly can level it at any tackle on the Ethereum blockchain with out requiring permission from the tackle’ proprietor. This permits web tricksters to focus on offensive domains at unsuspecting customers in an try and make it seem that they’re appropriating unsavory phrases and phrases by alternative.

Cuban picked up on this inherent issue, noting “it is apparent that it was despatched to me and I did not purchase it.” He requested Cointelegraph “Is it doable to cancel [the name] or reject the contract?” Digging deeper, it grew to become clear that the troll had made one thing of an error in judgement. There are three components to an ENS area — the Registrant, which is the proprietor, the Controller, which manages subdomains in addition to the place the area title factors, and the File, which notes the precise tackle the place cash are obtained when the area is enter right into a pockets.

Usually, when mischief makers level a website at an unsuspecting person’s tackle, they solely change both the Controller or the File. They don’t normally hand over whole management of the area itself. This explicit troll, who Cuban amusingly known as an “fool”, had as a substitute offered the total Registrant rights to his tackle. This allotted him unfettered possession and management of the area.

With that in thoughts, and with some technical assist from Cointelegraph, Cuban struck on a technique to one-up the silly troll and eliminate the title as soon as and for all. He altered the Controller, File, and eventually Registrant in order that they might every be owned by a burner tackle — i.e. an tackle whose non-public keys are nullified both by design or intention. In Mark’s case, this concerned creating a brand new throwaway pockets himself, with the target of creating it inaccessible as soon as his mission was full. When requested about his timeline for disposing of the pockets’s keys, he quipped:

“What keys? They’re gone.”

Because of this, the area now successfully has no proprietor. And so it should stay (at the very least till the registration expires.)

When confronted with questions as to how comparable possession quirks ought to be dealt with in future, Cuban maintained that the accountability for such transgressions finally falls on the builders of decentralized functions:

“It is a drawback that ENS goes to have to repair. There must be acceptance of a switch. In any other case the abuse shall be actually actually dangerous. It is a weak point within the system that must be mounted.”

Mark Cuban has been working to mature his stature throughout the blockchain group over the previous few months. Yesterday, he participated in an Ask Me Something session on Reddit, utilizing the chance to debate the way forward for distributed know-how and conventional finance. In January, he made headlines by evaluating crypto’s present trajectory to the dot com bubble — an period which paved the best way for a few of his preliminary success again within the late 90’s.
