We’re rolling out one genuine use case for AI and crypto each day this week — including reasons why you shouldn’t necessarily believe the hype. Today: How blockchain can fight the fakes.

Generative AI is extremely good at generating fake photos, fake letters, fake bills, fake conversations — fake everything. Near co-founder Illia Polosukhin warns that soon, we won’t know which content to trust.

“If we don’t solve this reputation and authentication of content (problem), shit will get really weird,” Polosukhin explains. “You’ll get phone calls, and you’ll think this is from somebody you know, but it’s not.”

“All the images you see, all the content, the books will be (suspect). Imagine a history book that kids are studying, and literally every kid has seen a different textbook — and it’s trying to affect them in a specific way.”

Blockchain can be used to transparently trace the provenance of online content so that users can distinguish between genuine content and AI-generated images. But it won’t sort out truth from lies.

“That’s the wrong take on the problem because people write not-true stuff all the time. It’s more a question of when you see something, is it by the person that it says it is?” Polosukhin says.

“And that’s where reputation systems come in: OK, this content comes from that author; can we trust what that author says?”

“So, cryptography becomes an instrument to ensure consistency and traceability and then you need reputation around this cryptography — on-chain accounts and record keeping to actually ensure that ‘X posted this’ and ‘X is working for Cointelegraph right now.’”

If it’s such a great idea why isn’t anyone doing it already?

There are a variety of existing supply chain projects that use blockchain to prove the provenance of goods in the real world, including VeChain and OriginTrail.

However, content-based provenance has yet to take off. The Trive News project aimed to crowdsource article verification via blockchain, while the Po.et project stamped a transparent history of content on the blockchain, but both are now defunct 

More recently, Fact Protocol was launched, using a combination of AI and Web3 technology in an attempt to crowdsource the validation of news. The project joined the Content Authenticity Initiative in March last year

When somebody shares an article or piece of content online, it is first automatically validated using AI and then fact-checkers from the protocol set out to double-check it and then record the information, along with timestamps and transaction hashes, on-chain.

“We don’t republish the content on our platform, but we create a permanent, on-chain record of it, as well as a record of the fact-checks conducted and the validators for the same,” founder Mohith Agadi told The Decrypting Story. 

And in August, global news agency Reuters ran a proof-of-concept pilot program that used a prototype Canon camera to store the metadata for photos on-chain using the C2PA standard.

It also integrated Starling Lab’s authentication framework into its picture desk workflow. With the metadata, edit history and blockchain registration embedded in the photograph, users can verify a picture’s authenticity by comparing its unique identifier to the one recorded on the public ledger.

Academic research in the area is ongoing, too. 

Is blockchain needed?

Technically, no. One of the issues hamstringing this use case is that you actually don’t need blockchain or crypto to prove where a piece of content came from. However, doing so makes the process much more robust.

So, while you could use cryptographic signatures to verify content, Polosukhin asks how the reader can be certain it is the right signature? If the key is posted on the originating website, someone can still hack that website.

Web2 deals with these issues by using trusted service providers, he explains, “but that breaks all the time.”

“Symantec was hacked, and they were issuing SSL certificates that were not valid. Websites are getting hacked — Curve, even Web3 websites are getting hacked because they run on a Web2 stack,” he says.

“So, from my perspective, at least, if we’re looking forward to a future where this is used in malicious ways, we need tools that are actually resilient to that.”

Don’t believe the hype

People have been discussing this use case for blockchain to fight “disinformation” and deep fakes long before AI took off, and there has been little progress until recently. 

Microsoft has just rolled out its new watermark to crack down on generative AI fakes being used in election campaigns. The watermark from the Coalition for Content Provenance Authenticity is permanently attached to the metadata and shows who created it and whether AI was involved.

The New York Times, Adobe, the BBC, Truepic, Washington Post and Arm are all members of C2PA. However, the solution doesn’t require the use of blockchain, as the metadata can be secured with hashcodes and certified digital signatures.

That said, it can also be recorded on blockchain, as Reuter’s pilot program in August demonstrated. And the awareness arm of C2PA is called the Content Authenticity Initiative, and Web3 outfits, including Rarible, Fact Protocol, Livepeer and Dfinity, are CAI members flying the flag for blockchain.

Trump’s use of presidential seal at memecoin event raises legal questions

Trump’s use of presidential seal at memecoin event raises legal questions

Trump’s use of presidential seal at memecoin event raises legal questions

President Donald Trump is facing scrutiny after speaking at a private event for top investors in his $TRUMP memecoin while standing behind a lectern emblazoned with the official presidential seal — a move that may violate federal law.

The event took place Thursday at Trump National Golf Club in Virginia, where Trump addressed 220 investors in his cryptocurrency project.

According to US law, the presidential seal cannot be used in any manner that could imply government approval or sponsorship. Violators can face fines or up to six months in prison.

Trump, who arrived at the club aboard a military helicopter, praised attendees and took aim at the Biden administration’s crypto stance.

When asked about potential conflicts of interest, White House Press Secretary Karoline Leavitt said the president’s involvement was personal. “It is not a White House dinner,” she told reporters. “It’s not taking place here at the White House.”

Trump features presidential seal at private properties

This isn’t the first time Trump has featured the presidential seal at his private properties. Forbes has previously reported its use as golf markers at several Trump-owned clubs.

In a May 22 letter to the Justice Department, 35 House members asked the public integrity section acting chief, Edward Sullivan, to launch an inquiry over the memecoin dinner to determine whether it violated the federal bribery statute or the foreign emoluments clause of the US Constitution. 

Under the emoluments clause, a US president is barred from accepting any gift from a foreign state without the approval of Congress.

Bloomberg reported that a majority of the attendees at the memecoin dinner were likely foreign nationals based on their connections to crypto exchanges. 

“US law prohibits foreign persons from contributing to US political campaigns,” said the letter. “However, the $TRUMP memecoin, including the promotion of a dinner promising exclusive access to the President, opens the door for foreign governments to buy influence with the President, all without disclosing their identities.”

Trump embraces crypto despite previous skepticism

Trump’s embrace of crypto marks a sharp turn from his skepticism during his first term. The $TRUMP memecoin, launched earlier this year, peaked at $74.34 before falling to $14.44 by May 22.

High-profile guests at the dinner included Tron founder Justin Sun, ex-NBA player Lamar Odom, and Asian crypto executives Sangrok Oh and Vincent Liu.

Sun, who reportedly invested over $40 million in $TRUMP tokens and spoke at the dinner, also has deep ties to Trump’s crypto ventures. He’s the top backer of World Liberty Financial, a Trump-affiliated firm currently under regulatory scrutiny.

Judge overturns fraud convictions in Mango Markets exploit case

Judge overturns fraud convictions in Mango Markets exploit case

A US federal judge has vacated key fraud and manipulation convictions against Avraham Eisenberg, the trader at the center of the case involving a $110 million exploit of the decentralized exchange Mango Markets.

On Friday, US District Judge Arun Subramanian ruled that the evidence presented at trial failed to support the jury’s conclusion that Eisenberg made materially false representations to Mango Markets.

The decision vacates Eisenberg’s convictions for commodities fraud and market manipulation and acquits him of a third charge, significantly weakening the government’s case.

Eisenberg, a self-proclaimed “applied game theorist,” was convicted in 2024 for artificially inflating the price of Mango’s MNGO token by over 1,300% in a matter of minutes and using the resulting gains as collateral to withdraw $110 million in crypto assets from the platform.

Judge sides with Eisenberg

The Justice Department argued that he deceived Mango’s smart contract-based lending system, but Eisenberg’s defense maintained that he merely exploited poorly designed, permissionless code — without making any false representations.

Judge Subramanian agreed, writing that “Mango Markets was permissionless and automatic,” meaning the system couldn’t be deceived in a legal sense. “There was insufficient evidence of falsity,” the judge added, siding with Eisenberg’s interpretation of DeFi mechanics.

The judge also rejected prosecutors’ argument that the case should be heard in New York. Eisenberg was in Puerto Rico at the time of the trades, and the court found that no meaningful activity tied to the alleged crime occurred in New York.

The DOJ had cited a Poughkeepsie-based Mango user and a third-party vendor in Manhattan, but the judge ruled these were not enough to establish proper venue.

The US government must now decide whether to refile the vacated charges, though the Trump administration has recently signaled a reduced focus on crypto enforcement. Eisenberg still faces civil suits from both the SEC and CFTC.

While this ruling clears Eisenberg in the Mango Markets case, he remains behind bars.

Eisenberg charged with child pornography

In a separate case, Eisenberg was sentenced to nearly four years in prison on May 1 after pleading guilty to possessing child pornography — a charge stemming from unrelated evidence uncovered during his arrest.

In December 2022, US federal law enforcement authorities arrested Eisenberg in Puerto Rico. FBI officials charged the hacker with one count of commodities fraud and one count of commodities manipulation.

jury found Eisenberg guilty of wire fraud, commodities fraud, and commodities manipulation in April 2024. The defense argued that the exploit was not a cybercrime and represented a “successful and legal trading strategy.”

Members of the US House of Representatives called for the Justice Department to investigate Donald Trump’s May 22 dinner for his top memecoin investors, citing concerns about “foreign influence over US policy decisions” and “potential corruption and emoluments clause violations.”

In a May 22 letter to the Justice Department, 35 House members asked the public integrity section acting chief, Edward Sullivan, to launch an inquiry over the memecoin dinner to determine whether it violated the federal bribery statute or the foreign emoluments clause of the US Constitution. 

Under the emoluments clause, a US president is barred from accepting any gift from a foreign state without the approval of Congress. Bloomberg reported that a majority of the attendees at the memecoin dinner were likely foreign nationals based on their connections to crypto exchanges. 

“US law prohibits foreign persons from contributing to US political campaigns,” said the letter. “However, the $TRUMP memecoin, including the promotion of a dinner promising exclusive access to the President, opens the door for foreign governments to buy influence with the President, all without disclosing their identities.”

The call for an investigation and a press conference asking Trump to “release the guest list” for the dinner both occurred hours before the event, which was held at the Trump National Golf Club outside Washington, DC. A group of protesters, joined by Senator Jeff Merkley, gathered outside the venue with signs stating “illegal crypto party” and “democracy is not for sale.”

Though some of the dinner attendees covered their faces with masks to conceal their identities, protesters and members of the media confirmed that Tron founder Justin Sun appeared at the event, as well as other Trump supporters who posted to social media. The complete list of attendees was not available at the time of publication. 

The memecoin dinner still has the potential to affect pending legislation in Congress

In addition to the call for a DOJ investigation, Democratic lawmakers in the House and Senate proposed legislation to address what they called “Trump’s crypto corruption” as Congress considered a bill to regulate stablecoins and a market structure bill. 

Several Senate Democrats who initially voted against advancing the stablecoin bill, called the GENIUS Act, later sided with Republicans to set up a debate in the chamber.

Representative Maxine Waters introduced a bill to limit the access of any US president, vice president, members of Congress and their families to cryptocurrencies. Members of the Senate will also propose an amendment to the GENIUS Act to address Trump’s connection to World Liberty Financial, a crypto platform backed by the president’s family that issued its USD1 stablecoin.
