<div>ZKPs can prove I'm old enough without telling you my age</div>

Opinion by: Andre Omietanski, General Counsel, and Amal Ibraymi, Legal Counsel at Aztec Labs

What if you could prove you’re over 18, without revealing your birthday, name, or anything else at all? Zero-knowledge proofs (ZKPs) make this hypothetical a reality and solve one of the key challenges online: verifying age without sacrificing privacy. 

The need for better age verification today

We’re witnessing an uptick in laws being proposed restricting minors’ access to social media and the internet, including in Australia, Florida, and China. To protect minors from inappropriate adult content, platform owners and governments often walk a tightrope between inaction and overreach. 

For example, the state of Louisiana in the US recently enacted a law meant to block minors from viewing porn. Sites required users to upload an ID before viewing content. The Free Speech Coalition challenged the law as unconstitutional, making the case that it infringed on First Amendment rights.

The lawsuit was eventually dismissed on procedural grounds. The reaction, however, highlights the dilemma facing policymakers and platforms: how to block minors without violating adults’ rights or creating new privacy risks.

Traditional age verification fails

Current age verification tools are either ineffective or invasive. Self-declaration is meaningless, since users can simply lie about their age. ID-based verification is overly invasive. No one should be required to upload their most sensitive documents, putting themselves at risk of data breaches and identity theft. 

Biometric solutions like fingerprints and face scans are convenient for users but raise important ethical, privacy, and security concerns. Biometric systems are not always accurate and may generate false positives and negatives. The irreversible nature of the data, which can’t be changed like a regular password can, is also less than ideal. 

Other methods, like behavioral tracking and AI-driven verification of browser patterns, are also problematic, using machine learning to analyze user interactions and identify patterns and anomalies, raising concerns of a surveillance culture.

ZKPs as the privacy-preserving solution

Zero-knowledge proofs present a compelling solution. Like a government ID provider, a trusted entity verifies the user’s age and generates a cryptographic proof confirming they are over the required age.

Websites only need to check the proof, not the excess personal data, ensuring privacy while keeping minors at the gates. No centralized data storage is required, alleviating the burden on platforms such as Google, Meta, and WhatsApp and eliminating the risk of data breaches.

Adopting and enforcing ZKPs at scale

ZKPs aren’t a silver bullet. They can be complex to implement. The notion of “don’t trust, verify,” proven by indisputable mathematics, may cause some regulatory skepticism. Policymakers may hesitate to trust cryptographic proofs over visible ID verification. 

There are occasions when companies may need to disclose personal information to authorities, such as during an investigation into financial crimes or government inquiries. This would challenge ZKPs, whose very intention is for platforms not to hold this data in the first place.

ZKPs also struggle with scalability and performance, being somewhat computationally intensive and tricky to program. Efficient implementation techniques are being explored, and breakthroughs, such as the Noir programming language, are making ZKPs more accessible to developers, driving the adoption of secure, privacy-first solutions. 

A safer, smarter future for age verification

Google’s move to adopt ZKPs for age verification is a promising signal that mainstream platforms are beginning to embrace privacy-preserving technologies. But to fully realize the potential of ZKPs, we need more than isolated solutions locked into proprietary ecosystems. 

Crypto-native wallets can go further. Open-source and permissionless blockchain-based systems offer interoperability, composability, and programmable identity. With a single proof, users can access a range of services across the open web — no need to start from scratch every time, or trust a single provider (Google) with their credentials.

ZKPs flip the script on online identity — proving what matters, without exposing anything else. They protect user privacy, help platforms stay compliant, and block minors from restricted content, all without creating new honeypots of sensitive data.

Google’s adoption of ZKPs shows mainstream momentum is building. But to truly transform digital identity, we must embrace crypto-native, decentralized systems that give users control over what they share and who they are online.

In an era defined by surveillance, ZKPs offer a better path forward — one that’s secure, private, and built for the future.

Trump reignites row with 'nasty' Sadiq Khan as Starmer responds

Donald Trump has reignited his row with London mayor Sir Sadiq Khan after calling him a “nasty person” who has done “a terrible job”.

During an hour-long news conference with Sir Keir Starmer in Scotland, the US president hit out at the Labour mayor, who has responded with his own snipey remarks.

Trump latest: US leader gives Putin new deadline to end war

Asked if he would visit London during his state visit in September, Mr Trump said: “I will, I’m not a fan of your mayor, I think he’s done a terrible job.

“A nasty person, I think.”

The prime minister then interrupted and said: “He’s a friend of mine.”

But the president added: “I think he’s done a terrible job but I will certainly visit London, I hope so.”

Sir Sadiq’s spokesperson then released a statement saying: “Sadiq is delighted that President Trump wants to come to the greatest city in the world.

“He’d see how our diversity makes us stronger not weaker; richer, not poorer.

“Perhaps these are the reasons why a record number of Americans have applied for British citizenship under his presidency.”

They noted that Sir Sadiq has won three mayoral elections, including when Mr Trump lost the US election in 2020.

This is not the first time Mr Trump and Sir Sadiq have locked horns.

During his first presidential term, Mr Trump called the London mayor a “stone cold loser who should focus on crime in London”.

Sir Sadiq then described Mr Trump as a “poster boy for racists”.

And in November 2024, after Mr Trump won his second term, Sir Sadiq said many Londoners would be “fearful” about what it would “mean for democracy”.

However, as Sir Keir tried to show diplomacy with Mr Trump after becoming PM, Sir Sadiq said he “wanted to work closely with the American president” ahead of his inauguration in January.

The London mayor said as somebody “who believes in democracy, and voting and elections, we should recognise the fact that Donald Trump is the elected president of the United States”.

But he added: “Let’s keep our fingers crossed that this president is different from the last time he was president.”
