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.

Planning reforms to 'rewire the system' and get Britain building - all while protecting wildlife

Major developers will only deal with one regulator under planning reforms which ministers say will “rewire the system” to get Britain building – all while protecting the environment. 

A review by former Labour adviser Dan Corry into Britain’s sluggish system of green regulation has concluded that existing environmental regulators should remain in place, while rejecting a “bonfire of regulations”.

But Mr Corry suggested there might be circumstances in which the government look at changing the wildlife and habit rules inherited from the EU, which protect individual species.

These lie at the centre of the controversy of a £120m bat tunnel – the shed in Aylesbury which protects a rare breed from future high speed trains.

Keir Starmer has declared war on £100m HS2 bat shed – but has he got a solution?
New planning bill could be the government’s most important – but will it work in practice?

The government has now explicitly ruled out any such change in this parliament.

More from Politics

Campaigners have questioned whether the changes go far enough and will make a major difference to the rate and scale of building in the UK.

Speaking to Sky News, Environment Secretary Steve Reed insisted that accepting nine of the recommendations from the Corry review would amount to wholesale reform.

The minister said: “We can get a win-win for economic growth and for nature. And that is why we are moving ahead with proposals such as appointing a lead regulator for major developments so that the developers don’t have to navigate the architecture of multiple regulators.

“They just work for a single regulator who manages all the others on their behalf. Simplifying the online planning portal.

“These are huge changes that will save developers billions of pounds and speed up decisions doing damage to the environment.”

Mr Reed insisted that there would be “no more bat tunnels” built, even though the Corry review suggests that more work needs to be done to look again at the relevant guidance.

It says: “Rapidly reviewing the existing catalogue of compliance guidance, including on protecting bats, will identify opportunities to remove duplication, ambiguity or inconsistency.

“Natural England has already agreed to review and update their advice to Local Planning Authorities on bats to ensure there is clear, proportionate and accessible advice available.”

The review will mean:

• Appointing one lead regulator for every major infrastructure project, like Heathrow expansion

• A review on how nature rules are implemented – but not the rules themselves

• Insisting regulators focus more on government priorities, particularly growth

Economist and former charity leader Mr Corry, who led the review, said it shows that “simply scrapping regulations isn’t the answer”.

“Instead we need modern, streamlined regulation that is easier for everyone to use. While short-term trade-offs may be needed, these reforms will ultimately deliver a win-win for both nature and economic growth in the longer run.”

However, Sam Richards from Britain Remade, a thinktank trying to get Britain growing, said that while the steps are welcome, the number of regulators that report to the environment department would remain the same before and after the review. He questioned whether this would have the impact ministers claimed.

Kentucky joins Vermont and South Carolina in dropping Coinbase staking suit

Kentucky joins Vermont and South Carolina in dropping Coinbase staking suit

Kentucky’s finance watchdog has dismissed its lawsuit against Coinbase over the exchange’s staking rewards program, following its peers in Vermont and South Carolina.

Kentucky’s Department of Financial Institutions filed the stipulation to dismiss jointly with Coinbase on April 1, ending the state’s legal action against the exchange first filed along with 10 other state regulators in June 2023.

Coinbase chief legal officer Paul Grewal posted to X on April 1, calling for Congress “to end this litigation-driven, state-by-state approach with a federal market structure law.”

Financial regulators from 10 states launched similar suits against Coinbase in June 2023, on the same day the Securities and Exchange Commission sued the exchange — a lawsuit the SEC dropped last month.

Seven suits against Coinbase still active

Alabama, California, Illinois, Maryland, New Jersey, Washington and Wisconsin are the seven states that are still continuing with their lawsuits, which all allege Coinbase breached securities laws with its staking rewards program.

Vermont was the first state to end its suit against Coinbase, with its Department of Financial Regulation filing an order to rescind the action on March 13, noting the SEC’s Feb. 27 decision to drop its action against the exchange and the likelihood of changes in the federal regulator’s guidance.

The South Carolina Attorney General’s securities division followed Vermont days later, dismissing its lawsuit in a joint stipulation with Coinbase on March 27.

Kentucky’s decision to drop its case against Coinbase follows just days after the state’s governor, Andy Beshear, signed a “Bitcoin Rights” bill into law on March 24 that establishes protections for crypto self-custody and exempts crypto mining from money transmitting and securities laws.

The axed state-level lawsuits come amid a stark policy change at the SEC, which has dropped or delayed multiple lawsuits against crypto companies that it filed under the Biden administration.

The federal securities watchdog has also created a Crypto Task Force that is engaging with the industry on how it should approach cryptocurrencies.

Sir Keir Starmer says US-UK trade talks 'well advanced' and rejects 'knee-jerk' response to Donald Trump tariffs

Sir Keir Starmer has said US-UK trade talks are “well advanced” ahead of tariffs expected to be imposed by Donald Trump on the UK this week – but rejected a “knee-jerk” response.

Speaking to Sky News political editor Beth Rigby, the prime minister said the UK is “working hard on an economic deal” with the US and said “rapid progress” has been made on it ahead of tariffs expected to be imposed on Wednesday.

But, he admitted: “Look, the likelihood is there will be tariffs. Nobody welcomes that, nobody wants a trade war.

“But I have to act in the national interest and that means all options have to remain on the table.”

Sir Keir added: “We are discussing economic deals. We’re well advanced.

“These would normally take months or years, and in a matter of weeks, we’ve got well advanced in those discussions, so I think that a calm approach, a collected approach, not a knee-jerk approach, is what’s needed in the best interests of our country.”

Keir Starmer

Downing Street said on Monday the UK is expecting to be hit by new US tariffs on Wednesday – branded “liberation day” by the US president – as a deal to exempt British goods would not be reached in time.

A 25% levy on car and car parts had already been announced but the new tariffs are expected to cover all exports to the US.

Jonathan Reynolds, the business and trade secretary, earlier told Sky News he is “hopeful” the tariffs can be reversed soon.

But he warned: “The longer we don’t have a potential resolution, the more we will have to consider our own position in relation to [tariffs], precluding retaliatory tariffs.”

He added the government was taking a “calm-headed” approach in the hope a deal can be agreed but said it is only “reasonable” retaliatory tariffs are an option, echoing Sir Keir’s sentiments over the weekend.

Tariff announcement on Wednesday

Mr Trump has been threatening tariffs – import taxes – on countries with the biggest trade imbalances with the US.

However, over the weekend, he suggested the tariffs would hit all countries, but did not name them or reveal which industries would be targeted.

‘Everything on table over US tariffs’

Mr Trump will unveil his tariff plan on Wednesday afternoon at the first Rose Garden news conference of his second term, the White House press secretary said.

“Wednesday, it will be Liberation Day in America, as President Trump has so proudly dubbed it,” Karoline Leavitt said.

“The president will be announcing a tariff plan that will roll back the unfair trade practices that have been ripping off our country for decades. He’s doing this in the best interest of the American worker.”

Trump’s tariffs: What can we expect?

Tariffs would cut UK economy by 1%

UK government forecaster the Office for Budget Responsibility (OBR) said a 20 percentage point increase in tariffs on UK goods and services would cut the size of the British economy by 1% and force tax rises this autumn.

Global markets remained flat or down on Monday in anticipation of the tariffs, with the FTSE 100 stock exchange trading about 1.3% lower on Monday, closing with a 0.9% loss.

On Wall Street, the S&P 500 rose 0.6% after a volatile day which saw it down as much as 1.7% in the morning.

However, the FTSE 100 is expected to open about 0.4% higher on Tuesday, while Asian markets also steadied, with Tokyo’s Nikkei 225 broadly unchanged after a 4% slump yesterday.
