Vitalik unveils Lean Ethereum for post-quantum protection

Ethereum developers have revealed a ‘Lean Ethereum‘ roadmap that seeks to simplify the blockchain’s base layer while preparing it for post-quantum security. The proposal was discussed by co-founder Vitalik Buterin and researcher Justin Drake during a Berlin conference session.

The plan prioritises three core goals: enhanced security through post-quantum signatures, reduced complexity in Ethereum’s structure, and improved efficiency to lower latency and costs.

Developers are already exploring four research tracks, including a three-step-finality protocol, quantum-resistant signatures, zero-knowledge virtual machines, and improved data layering through erasure coding.

Under the broader ‘lean’ concept, Ethereum may soon adopt lean staking, verifiability for low-power devices, and simplified cryptographic design. Modular logic and formal checks are part of the plan, aligned with zkEVM pilots and inclusion list development.

Although the roadmap doesn’t suggest an immediate upgrade, the Ethereum Foundation described it as a cohesive strategy that ties current innovation to long-term resilience. Core teams will prototype components and assess trade-offs in ongoing working group discussions.

AI traffic wars: ChatGPT dominates, Gemini and Claude lag behind

ChatGPT has cemented its position as the world’s leading AI assistant, racking up 5.5 billion visits in May 2025 alone—roughly 80% of all global generative AI traffic. That’s more than the combined total of Google’s Gemini, DeepSeek, Grok, Perplexity, and Claude—doubled.

With over 500 million weekly active users and a mobile app attracting 250 million monthly users last autumn, Ch a tGPT has become the default AI tool for hundreds of millions globally.

Despite a brief dip in early 2025, OpenAI quickly reversed course. Its partnership with Microsoft helped, but ChatGPT works well for the average user.

While other platforms chase benchmark scores and academic praise, ChatGPT has focused on accessibility and usefulness—proven decisive qualities.

Some competitors have made surprising gains. Chinese start-up DeepSeek saw explosive growth, from 33.7 million users in January to 436 million visits by May.

Operating at a fraction of the cost of Western rivals—and relying on older Nvidia chips—DeepSeek is growing rapidly in Asia, particularly in China, India, and Indonesia.

Meanwhile, despite integration across its platforms, Google’s Gemini lags behind with 527 million visits, and Claude, backed by Amazon and Google, is barely breaking 100 million despite high scores in reasoning tasks.

The broader impact of AI’s rise is reshaping the internet. Legacy platforms like Chegg, Quora, and Fiverr are losing traffic fast, while tools focused on code completion, voice generation, and automation are gaining traction.

In the race for adoption, OpenAI has already won. For the rest of the industry, the fight is no longer for first place—but for who finishes next.

Tether invests in Canadian gold company to strengthen its reserves

Tether has acquired nearly a third of a Canadian gold firm as part of its expanding dual investment strategy in Bitcoin and gold. The firm has bought 78.4 million shares in Elemental Altus for CA$121.5 million, securing 31.9% of the company.

The company, best known for minting USDT, now holds over 100,000 Bitcoin and nearly 80 tons of physical gold. It describes this as a ‘dual pillar strategy’ designed to safeguard value and improve financial resilience amid rising inflation and monetary uncertainty.

Tether CEO Paolo Ardoino said Bitcoin and gold offer complementary protections, with the former being a decentralised hedge and a long-trusted store of value. The company has also issued XAUT, a stablecoin backed by gold, currently valued at over $833 million.

USDT continues to dominate global trading volumes and has gained popularity in emerging markets as a digital dollar alternative. Tether says holding gold and crypto strengthens its traditional and decentralised finance position.

Trump highlights crypto plans at Coinbase summit

US President Donald Trump sent a prerecorded message to Coinbase’s State of Crypto Summit, reaffirming his commitment to advancing crypto regulation in the US.

The administration is working with Congress to pass the GENIUS Act supporting dollar-backed stablecoins and clear market frameworks.

Congress is preparing to vote on the GENIUS Act in the Senate, while the House is moving forward with the CLARITY Act. The latter seeks to clarify the regulatory roles of the SEC and the Commodity Futures Trading Commission concerning digital assets.

Both bills form part of a broader effort to create a clear legal environment for the crypto industry.

Some Democrats oppose Trump’s crypto ties, especially the family-backed stablecoin from World Liberty Financial. Despite tensions, Trump continues promoting his crypto agenda through conferences and videos.

Crypto conferences face rising phishing risks

Crypto events have grown rapidly worldwide in recent years. Unfortunately, this expansion has led to an increase in scams targeting attendees, according to Kraken’s chief security officer, Nick Percoco.

Recent conferences have seen lax personal security, with exposed devices and careless sharing of sensitive information. These lapses make it easier for criminals to launch phishing campaigns and impersonation attacks.

Phishing remains the top threat at these events, exploiting typical conference activities such as QR code scanning and networking. Attackers distribute malicious links disguised as legitimate follow-ups, allowing them to gain access to wallets and sensitive data with minimal technical skill.

Use of public Wi-Fi, unverified QR codes, and openly discussing high-value trades in public areas further increase risks. Attendees are urged to use burner wallets and verify every QR code carefully.

The dangers have become very real, highlighted by violent crimes in France, where prominent crypto professionals were targeted in kidnappings and ransom demands. These incidents show that risks are no longer confined to the digital world.

Basic security mistakes such as leaving devices unlocked or oversharing personal information can have severe consequences. Experts call for a stronger security culture at events and beyond, including multi-factor authentication, cautious password management, and heightened situational awareness.

AI video tool Veo 3 Fast rolls out for Gemini and Flow users

Google has introduced Veo 3 Fast, a speedier version of its AI video-generation tool that promises to cut production time in half.

Now available to Gemini Pro and Flow Pro users, the updated model creates 720p videos more than twice as fast as its predecessor—marking a step forward in scaling Google’s video AI infrastructure.

Gemini Pro subscribers can now generate three Veo 3 Fast videos daily as part of their plan. Meanwhile, Flow Pro users can create videos using 20 credits per clip, significantly reducing costs compared to previous models. Gemini Ultra subscribers enjoy even more generous limits under their premium tier.

The upgrade is more than a performance boost. According to Google’s Josh Woodward, the improved infrastructure also paves the way for smoother playback and better subtitles—enhancements that aim to make video creation more seamless and accessible.

Google also tests voice prompt capabilities, allowing users to express video ideas and watch them materialise on-screen.

Although Veo 3 Fast is currently limited to 720p resolution, it encourages creativity through rapid iteration. Users can experiment with prompts and edits without perfecting their first try.

While the results won’t rival Hollywood, the model opens up new possibilities for businesses, creators, and filmmakers looking to prototype video ideas or produce content without traditional filming quickly.

Czechia bids to host major EU AI computing centre

Czechia is positioning itself to host one of the European Union’s planned AI ‘gigafactories’—large-scale computing centres designed to strengthen Europe’s AI capabilities and reduce dependence on global powers like the United States.

Jan Kavalírek, the Czech government’s AI envoy, confirmed to the Czech News Agency that talks with a private investor are progressing well and potential locations have already been identified.

While the application for the EU funding is not yet final, Kavalírek said, ‘We are very close.’ The EU has allocated around €20 billion for these AI infrastructure projects, with significant contributions also expected from private sources.

Germany and Denmark are also vying to host similar facilities. If successful, the bid made by Czechia could transform the country into a key AI infrastructure hub for Europe, offering powerful computational resources for sectors such as public administration, healthcare, and finance.

Lukáš Benzl, director of the Czech Association of Artificial Intelligence, described the initiative as a potential ‘motor for the AI economy’ across the continent.

Canva makes AI use mandatory in coding interviews

Australian design giant Canva has revamped its technical interview process to reflect modern software development, requiring job candidates to demonstrate their ability to use AI coding assistants.

The shift aims to assess better how candidates would perform on the job, where tools like Copilot and Claude are already part of engineers’ daily workflows.

Previously, interviews focused on coding fundamentals without assistance. Now, candidates must solve engineering problems using AI tools in ways that reflect real-world scenarios, demanding effective prompting and judgement rather than simply getting correct outputs.

The change follows internal experiments where Canva found that AI could easily handle traditional interview questions. Company leaders argue that the old approach no longer measured actual job readiness, given that many engineers rely on AI to navigate codebases and accelerate prototyping.

By integrating AI into hiring, Canva joins many firms that are adapting to a tech workforce increasingly shaped by intelligent automation. The company says the goal is not to test if candidates know how to use AI but how well they use it to build solutions.

Meta hires top AI talent from Google and Sesame

Meta is assembling a new elite AI research team aimed at developing artificial general intelligence (AGI), luring top talent from rivals including Google and AI voice startup Sesame.

Among the high-profile recruits is Jack Rae, a principal researcher from Google DeepMind, and Johan Schalkwyk, a machine learning lead from Sesame.

Meta is also close to finalising a multibillion-dollar investment in Scale AI, a data-labelling startup led by CEO Alexandr Wang, who is also expected to join the new initiative.

The new group, referred to internally as the ‘superintelligence’ team, is central to CEO Mark Zuckerberg’s plan to close the gap with competitors like Google and OpenAI.

Following disappointment over Meta’s recent AI model, Llama 4, Zuckerberg hopes the newly acquired expertise will help improve future models and expand AI capabilities in areas like voice and personalisation.

Zuckerberg has taken a hands-on approach, personally recruiting engineers and researchers, sometimes meeting with them at his homes in California. Meta is reportedly offering compensation packages worth tens of millions of dollars, including equity, to attract leading AI talent.

The company aims to hire around 50 people for the team and is also seeking a chief scientist to help lead the effort.

The broader strategy involves investing heavily in data, chips, and human expertise — three pillars of advanced AI development. By partnering with Scale AI and recruiting high-profile researchers, Meta is trying to strengthen its position in the AI race.

Meanwhile, rivals like Google are reinforcing their defences, with Koray Kavukcuoglu named as chief AI architect in a new senior leadership role to ensure DeepMind’s technologies are more tightly integrated into Google’s products.
