The G7 urges states and companies to switch now to quantum-resistant cryptography. Its report of September 3, 2026, mentions neither bitcoin, nor exchanges, nor blockchain, but targets the component on which every wallet depends: the public key signature, which a sufficiently powerful quantum computer can break.
ByteDance has just closed a syndicated loan of 29.6 billion dollars. It is the second largest dollar transaction completed in Asia this year. For TikTok's parent company, the goal is clear: to finance its expansion in AI without relying solely on its profits.
A new data leak expands the incident affecting hardware wallet buyers. Trezor reports that a breach at its logistics partner Shipmonk exposed information of an additional 67,000 American customers. The affected files were supposed to be deleted from the provider's systems but remained accessible. The impacted orders date from November 2019 to August 2021. With the 13,689 recorded customers, the incident concerns about 80,000 people, without compromising wallets, private keys, or backups.
OpenAI launched GPT-6 Astra on September 3, 2026, its first model classified as "Critical" in cybersecurity: according to the company, it discovers unknown vulnerabilities and writes the corresponding exploit without human guidance at each step. Its president Greg Brockman sees a possible milestone towards general artificial intelligence. For crypto, the stake is not theoretical, and it is already quantified. As early as February 2026, the EVMbench benchmark, published by OpenAI with Paradigm and OtterSec, measured this capability on smart contracts: the best agent exploited 72.2% of the tested vulnerabilities.
One week after the European Blockchain Convention, Barcelona is back at it on the technology front. AI Summit Barcelona takes place on September 22 and 23, 2026, at the World Trade Center, on the port. It is only the second edition, but its ambition is enormous: to grow from 1,500 attendees last year to more than 10,000 this year, with NVIDIA, Google, Microsoft and Anthropic on the bill. Here is what you need to know, along with the code reserved for the Cointribune community.
Ethereum hits an unprecedented blob-per-block record. Rollup activity, fees and network capacity reveal both progress and vulnerability.
After reaching a peak at the end of 2025, the computing power that secures the Bitcoin network is experiencing an unusual decline. Rapha Zagury, CEO of Twenty One Capital, calls this situation the first "bear market of the hashrate." This decline mainly reflects the deterioration of mining profitability. However, the phenomenon is amplified by artificial intelligence, as many operators are now dedicating their energy infrastructures to long-term computing contracts.
The GPU shortage succeeded where no manifesto had. It turned "decentralized AI", until recently just a slogan, into a real market. High-end accelerators have been out of stock for months, with lead times stretching past a year, and that scarcity pushed developers toward networks that pool idle hardware from around the world. Except the label "decentralized AI platform" now covers very different realities, and confusing them is the surest way to pick the wrong one. Renting a GPU is not the same as training a model. Scoring machine-learning outputs is not hosting an unrestricted LLM. This guide sorts the main players of 2026 by what they actually do, weighs the strengths and blind spots of each, and sets an outsider, Qubic, against the rest: the only network on this list where mining itself trains neural networks. No investment advice follows, only a map of the landscape.
Hacking, phishing, or just a bug? X investigates an unprecedented wave targeting the platform's most followed crypto accounts. The details.
A nostalgic tweet, a power transfer worth 4,600 billion dollars, and a silence that says a lot about crypto. John Ternus officially takes the helm of Apple this Tuesday. Between a keynote within eight days, the OpenAI lawsuit, and a complete lack of position on bitcoin, the new boss has no time to catch his breath.
Eric Trump is bragging about fat margins and machines that never clock out, while Forbes claims the real numbers look a lot uglier, leaving the president’s son and his critics in a full-blown Texas-sized brawl over the true cost of mined bitcoin.
ECB official Isabel Schnabel urges central banks to embrace blockchain. Explore what this shift means for crypto.
The acquisition of Cursor by SpaceX is already starting to change the AI market. OpenAI wants to withdraw its models from the code editor starting November 12. Anthropic takes the opposite direction: Claude will remain available and will even benefit from more computing capacity. Cursor thus finds itself in the middle of the old battle between Elon Musk and Sam Altman.
Security remains a top priority across crypto, yet losses keep climbing, with over $3.63 billion stolen since 2025. CEXes are most exposed through private key compromise, while DEXes face smart contract exploits, increasingly compounded by fake UIs and malicious integrations. The actors have evolved just as fast. Rogue individuals have given way to organized cartels and state-sponsored groups, including North Korean hackers, who now use mixers, bridges, and staggered withdrawals to stay untraceable. This report examines the shifting threat landscape, from auditing and insurance protocols to the security infrastructure CEXes like Toobit deploy to protect users. We’ve summarized the key highlights, but be sure to dig into the full 15 slides in the full report here.
Ripple released a roadmap whose role is to make the XRP Ledger compatible with post-quantum signatures by 2028. Indeed, the project plans tests, a coexistence period between the old and new systems, as well as a global network migration. However, this protection is not yet activated on the main network. No computer is yet capable of calculating the private keys used to control XRP accounts.
Kevin Warsh believes that artificial intelligence is likely to permanently change the growth potential of the United States. In his first speech at Jackson Hole as Federal Reserve chairman, he described the current period as a "turning point in history." However, he admits that the Fed still does not know when productivity gains will appear, how employment will progress, and which companies will capture the created value. These questions therefore do not yet influence rate decisions.
Before the end of this year, Sam Altman announces that OpenAI will have an internal system which he will designate as general artificial intelligence. However, the leader admits that the company has not yet crossed this stage. This projection is mainly based on Astra, a new family of models capable of performing research tasks over several days. However, no autonomous test can certify that OpenAI is really on the threshold of AGI.
Ethereum specialists issue the proposal to rebuild the contract that gives validators the ability to deposit their ETH. Their intention is to authorize new cryptographic systems to relinquish the BLS signatures currently used. Nearly 42.4 million ETH, valued at nearly 104 billion dollars, depend on this format. The project remains a working document. It does not choose any post-quantum algorithm and does not yet ensure network protection against any attack.
The Tron network has just passed a new milestone with more than 400 million registered accounts. This growth comes less than three years after crossing 200 million accounts and confirms its rise. Since its launch in June 2018, the network has gradually established itself in stablecoin transfers. Its cumulative volume approaches 30 trillion dollars, while USDT is the main driver of this usage.
The artificial intelligence company Anthropic is preparing to offer investors a total addressable market reaching more than 30,000 billion dollars. This amount represents theoretical annual revenues attainable if the firm manages to capture 100% of the activities it considers automatable thanks to AI. Such an estimate comes as the Claude designer is about to go public and tries to justify its massive capital needs.
In the United States, 39 banking associations prepare a crypto blockchain network dedicated to stablecoins and tokenized deposits. Details!
A possible sale of Hugging Face raises questions about the value of platforms that structure the open source ecosystem again. According to Business Insider, the company has reportedly hired a bank to probe buyers, with a potential valuation of 13 billion dollars or even more. No agreement exists yet and the buyers remain unknown. This hypothesis comes a few weeks after an intrusion related to an OpenAI AI agent, adding a new issue to this file already followed by global investors.
Privacy is now an increasingly important area of research in modern cryptography. On Friday, Vitalik Buterin published the third part of his series dedicated to cryptographic obfuscation. This time, he studies "local mixing," a method that abandons lattices and elliptic curves. His approach is rather inspired by hash functions and symmetric cryptography. This approach hides the internal logic of a program while preserving its operation, with implications for privacy on the blockchain.
The Canadian hardware wallet is evolving its security after a theft exceeding $114 million. Coldcard releases a new corrected firmware version after an analysis conducted with several AI models. This study was not limited to the initial random number generator. It also examined transactions, USB exchanges, and updates. Affected users must, however, renew their main keys before any fund transfers.
Alibaba regains a pace it hadn’t known for about three years. The Chinese group reports 268.95 billion yuan in revenue for its first fiscal quarter, nearly 40 billion dollars and a 9% increase year-on-year. Cloud accelerates by 45%. AI-related products notably record a twelfth consecutive quarter of triple-digit growth.
The hacking of the Directorate General of Public Finances pushes the French State to review its cybersecurity strategy. Faced with vulnerabilities affecting administrations and exposing sensitive data, the executive wants to deeply strengthen its digital audits. A response worthy of a threat that now goes beyond public systems alone. The stolen information can feed social engineering campaigns and directly target citizens, including crypto holders. Behind this shift lies a major question: that of French digital sovereignty.
The ECB warns of a stock market correction related to AI. A focus on the €440 billion of European exposure and the risks for the crypto market.
Minnesota is going directly after Grok. The US state accuses xAI's AI of facilitating the creation of realistic sexual images from photos of identifiable individuals. A new law now bans this type of tool in the state. xAI wants to have it suspended. The conflict is now playing out in court.
Ethereum is preparing a major shift. After years dominated by the quest for scalability, native privacy is now at the heart of the network's roadmap. Toni Wahrstätter, a researcher at the Ethereum Foundation, revealed the priorities studied for Hegotá, an update scheduled for 2027. Private transactions, censorship resistance, and architectural choices will now have to be balanced, while Glamsterdam is still expected by the end of 2026. Behind these technical decisions lies a strategic question: how far can Ethereum protect its users without compromising its scaling?
SafePal reveals a data breach affecting nearly 40,000 customers. Names, addresses, and purchases were exposed, but no crypto funds were compromised.
