The Google Quantum AI team published a paper in Science, announcing that a technique called magic state cultivation reduces errors by about 40 times on the Willow processor, producing logical fidelity of 99.99% for T states. Magic states are one-time resources required to run useful quantum programs, consumed with each use; according to estimates cited by Google, the cost of producing magic states can account for up to 95% of a quantum computer's total capacity, leaving very limited space for actual computation.The previous standard approach was magic state distillation proposed by physicists Sergei Bravyi and Alexei Kitaev in 2004, which required a large number of qubit factories dedicated solely to this task. Google researchers proposed a cheaper cultivation route in 2024, which behaves more like a filter: injecting rough magic states into a small area of the chip, running a series of checks on them, discarding all attempts found to be defective, and allowing the passers to gradually expand. In the experiments, only about 8% of attempts passed all checks, meaning that more than 90% of attempts had to be discarded for each clean state retained.The cultivation technology is one of the supports for Gidney's 2025 estimate that RSA-2048 encryption could be broken by fewer than a million noisy qubits, a reduction of 20 times from the 20 million estimated in 2019. This experiment used up to 54 of the 105 qubits in Willow, with the paper noting that breaking the RSA-2048 key requires magic states with an error rate of about one in ten billion, which is about a million times cleaner than this result.

According to Bloomberg, Coinbase co-founder Fred Ehrsam is betting personal funds on Venezuela's oil industry. He referred to this opportunity to become a significant oil producer as an "excellent opportunity" and compared it to the once-in-a-generation investment opportunities that helped him join the ranks of billionaires.The startup founded by Fred Ehrsam, Primavera, has recently signed multiple contracts with the state-owned oil company Petróleos de Venezuela S.A. (PDVSA) and is preparing to take over the operations of several oil fields in the country.Primavera has also hired senior oil industry professionals from Chevron and Occidental Petroleum to assist in building the necessary infrastructure to support the production of conventional oil and heavy crude.

According to PRNewswire, the publicly traded company Universal Safety Products (UUU) announced that it will be renamed DeFi Capital Markets on October 19 and will trade under the new ticker "DCM." In the future, it will gradually cease its original product business and focus on asset tokenization, digital assets, market making, as well as quantitative trading and blockchain financial markets.

According to CoinDesk, Ethereum co-founder Vitalik Buterin has released a long-term roadmap, referred to as Streamlining Ethereum. The vision proposes that by 2030, Ethereum will surpass a mere blockchain ledger and plans to completely restructure the protocol in the next three to four years.The transformation includes expanding transaction throughput by approximately 1000 times, introducing zero-knowledge proofs to enhance privacy and combat quantum computing threats. By 2030, the network is expected to accommodate 2TB of traditional dynamic state data, along with an additional 100TB of new scalable storage, to achieve underlying state separation and optimization. The vision also aims to establish Ethereum as an infrastructure driven by cryptographic validation, with applications extending from finance to social systems. Most developers support this plan, although some voices believe the implementation timeline is somewhat delayed.

According to the Financial Times, the South Korean Deputy Prime Minister recently stated, "Artificial intelligence should be regarded as a fundamental infrastructure like 'electricity,' and every South Korean citizen should be able to use it affordably without worrying about costs." Last year, South Korean President Lee Jae-myung stated that this technology has brought South Korea to "a significant historical turning point," and asked, "Are we going to continue to act as followers who may be left behind, or become leaders who can seize unlimited opportunities?" To answer this question, the government last month selected domestic telecom companies SK Telecom and KT, as well as internet service provider Kakao, to lead the implementation of the "Universal Artificial Intelligence" plan, aimed at allowing South Korea's 51.6 million citizens to use services similar to ChatGPT and personal AI assistants for free. The South Korean Deputy Prime Minister clearly stated on social media that despite concerns that technology may spiral out of control and lead to catastrophic consequences, South Korea remains determined to become "one of the top three countries in artificial intelligence." He wrote, "Currently, we have no room to slow down the pace of artificial intelligence development. We will accelerate, but we will do so more safely."

Two ChatGPT users from California filed a proposed class action lawsuit against OpenAI in the United States District Court for the Northern District of California this month, accusing the company of failing to adequately inform users that their real conversations were being handed over to external contractors for processing. The lawsuit was served to OpenAI on September 2, focusing on its internal initiative Project Lily. According to the complaint, "AI data reviewers" and "chatbot evaluators" recruited through a third-party staffing company read real ChatGPT prompts and complete conversations, summarize user intent, and score and comment on responses from four models on a scale of 1 to 7.This process is known in the industry as reinforcement learning from human feedback (RLHF), which is a fundamental method for enhancing chatbot capabilities. The complaint states that users were never explicitly informed that a person, rather than a machine, might be reading their conversations. OpenAI filters conversations through an automated system before human review, but the complaint alleges that the filters cannot intercept all content, and personal details sometimes still reach contractors. 404 Media first reported on the project on September 14 and found that the reviewers' dashboard included "user memory summaries," which could expose users' approximate locations, occupations, or private life information, even though usernames had been removed.OpenAI stated that such reviews aim to reduce two behaviors: chatbots behaving too much like humans and overly catering to users, referred to by researchers as "flattery." The complaint raises eight legal claims, including violations of California's Unfair Competition Law, Consumer Privacy Act, and common law claims for intrusion into private affairs, with the plaintiffs seeking damages, restitution of unjust enrichment, and punitive damages.

The cross-chain asset protocol Universal has announced its shutdown. The protocol will continue to operate normally for the next 60 days, until November 17, 2026. Universal was launched two years ago to build Universal Assets (uAssets), bringing assets such as SOL, XRP, and DOGE into a new ecosystem, supported 1:1 by underlying assets, and has supported over 80 types of assets.The team stated that the scale has not reached a long-term sustainable level, hence the decision to shut down. According to the tokenized asset data platform RootData, Universal announced last February that it had completed a $9 million financing round, led by a16z Crypto, with participation from Coinbase Ventures and others.

Bitget's Chief Legal Officer Hon Ng released an open letter on the occasion of the 8th anniversary. As the platform continues to evolve towards a panoramic exchange (UEX), Bitget has further upgraded its Proof of Reserves (PoR) system, expanding the range of verifiable assets from the original 4 cryptocurrencies to 19 major assets. Data shows that as of September 2026, Bitget has consecutively released 46 PoR reports.In the letter, Hon Ng pointed out, "Growth and responsibility have never been two independent matters." As the platform's scale, asset categories, and market boundaries continue to expand, security, transparency, and compliance standards also need to be upgraded in tandem. "Making trust visible and verifiable has always been an important cornerstone of Bitget's commitment to long-termism."In terms of security systems, the account side covers 2FA, FIDO2, WebAuthn Passkeys, and anti-phishing codes, while the platform's security mechanisms integrate withdrawal protection, abnormal behavior detection, and anti-fraud systems, providing backend support for every user operation. The "Market Order and Token Responsibility Framework" launched this year further strengthens ongoing monitoring and risk management for listed assets, project parties, and market makers. Continuous optimization of mechanisms and transparency initiatives maintain a fair and orderly trading environment.In terms of compliance, Bitget has obtained corresponding registrations, licenses, or regulatory approvals in multiple jurisdictions, including Argentina, Australia, New Zealand, Switzerland, and the United Kingdom, and continues to improve its compliance systems such as KYC, KYB, AML, CFT, and sanctions list screening to adapt to the regulatory requirements of different markets and asset categories.

According to CoinDesk, the Ethereum Glamsterdam upgrade has continued to confirm blocks after adopting new block construction rules this week, passing key tests and paving the way for its planned launch on the Sepolia public testnet on October 6. The Nethermind client subsequently completed performance tests involving one of the biggest changes in Glamsterdam, with all 2,302 tests passing, processing 57.07 billion gas in 3 minutes and 15 seconds, averaging about 2.9 billion gas per second.The benchmark measures the speed of the Nethermind execution software rather than the entire network, testing block-level access lists. This mechanism informs Ethereum nodes in advance about which accounts and storage data will be used in the block, allowing nodes to fetch data and check unrelated transactions simultaneously, whereas the current Ethereum mostly processes related work sequentially, limiting the amount of activity each block can accommodate. About an hour after the testnet launch, Glamsterdam raised the block gas limit from 60 million to 200 million, freeing up space for more payments, token swaps, and other activities per block.The 200 million gas limit allows Ethereum to absorb more activity before users start bidding for block space, thereby alleviating fee spikes during transaction surges or when popular tokens are launched. Larger blocks are also harder to verify, which may make it difficult for small-scale operators to keep up. Glamsterdam aims to gain additional capacity without excessively increasing chain operating costs. This upgrade also extends the block data propagation time from about 2 seconds to 9 seconds and plans to incorporate the handover and payment of block construction and verification into Ethereum's own rules, reducing reliance on external relay services.

Bitget launched the "VIP Summit" program on its 8th anniversary, opening a direct channel to VIP 7 for professional traders. Eligible historical high-level VIPs and newly promoted VIPs can apply for a 30-day VIP 7 experience card without needing to upgrade step by step. During the event, completing trading challenges can also extend the VIP 7 experience period to 4 months, with opportunities to receive limited gifts and exclusive dinner invitations.The VIP Summit program is centered around "Ultimate Rates, Ultimate Trading," targeting different types of professional traders such as newly promoted VIPs, other VIPs, and historical VIPs. It establishes three main channels: VIP upgrades, TradFi challenges, and peak privileges, further expanding trading rights and exclusive benefits. VIP benefits include discounts on trading fees, borrowing rates, advanced APIs, unified trading account (UTA) infrastructure, and exclusive VIP services, addressing the core needs of professional traders regarding cost, efficiency, and service.This program is based on research from over 300 VIP users, with trading costs and execution efficiency identified as the most important factors for professional traders, forming the core basis for the event's design. As a key initiative for the next phase of Bitget UEX, this program further focuses on professional and high-net-worth traders, continuously improving the platform's system in terms of trading rights, capital efficiency, and exclusive services. The participation period for the event ends on October 31, and more details can be found on the Bitget official platform.

Google (GOOG.O) has launched Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking, two models that are currently its most outstanding conversational artificial intelligence models.

Bitget celebrates its 8th anniversary, and CEO Gracy has released an anniversary open letter. She candidly stated that a year ago, when Bitget proposed the panoramic exchange UEX strategy, there were many doubts from the outside world, but the team chose to respond with product implementation. She mentioned that the starting point of UEX is to solve the fragmentation of assets, accounts, time, and geography, allowing users to trade high-quality global assets in one stop. Now, more and more leading exchanges are beginning to layout traditional financial trading, and Gracy referred to 2025 to 2026 as the "Year of Multi-Asset Trading."In her letter, Gracy wrote that over the past year, Bitget has transitioned from a "follower" to a "leader in product innovation," successively launching products such as stock perpetual contracts, Pre-IPO, cross-asset unified accounts, rToken, and Hong Kong stock Quanto contracts. Data shows that the peak trading volume of non-crypto assets has accounted for 40% of the platform's total trading volume, with daily trading volumes of TradFi contracts and CFDs both exceeding $10 billion, and the cumulative number of rToken transactions surpassing 3 million.Regarding the next phase, institutional business will become the core direction of Bitget. By the second quarter of 2026, the net asset scale of Bitget's institutional clients is expected to grow by 45% compared to the third quarter of 2025, with the number of core active market makers increasing from 90 to 248. In the future, the platform will continue to optimize trading execution, asset security, and institutional service links. Gracy concluded her open letter by stating, "The pursuit of trading excellence is never complete; it is always in progress. The era of multi-asset trading has just begun."
