December 29, China People's Bank Vice Governor Lu Lei publicly announced that the "Action Plan for Further Strengthening the Digital Renminbi Management Service System and Related Financial Infrastructure Construction" will be officially implemented on January 1, 2026. The digital renminbi will transition from the "Digital Cash" phase to the "Digital Deposit" 2.0 era. The core highlight of this transformation is that the balance of real-name digital renminbi wallets will start earning interest, bringing tangible benefits to users.
According to the deployment of the "Action Plan," banking institutions will accrue interest on the balances of first, second, and third-class real-name digital renminbi wallets, with interest rates referencing the bank's current deposit rates. Users do not need to take any additional actions, and the payment experience will remain unaffected. Meanwhile, anonymous fourth-class wallets opened with just a mobile phone number will still retain small payment functions, but their balances will not accrue interest for now, balancing convenience with compliance requirements.

According to ichaingo data, the US Bitcoin spot ETF experienced a net outflow of approximately $19.3 million yesterday, marking the seventh consecutive day of net outflows. The specific inflow and outflow situations for ETFs such as BlackRock, Fidelity, Ark & 21Shares, and Invesco vary, with most ETFs showing no significant fund movements for now.

Law enforcement agencies successfully tracking Bitcoin ransom funds are often depicted as a victory of blockchain transparency over the underground economy. However, this triumphant picture may conceal a more critical turning point: the victory only sweeps the surface of technological innovation, forcing dark activities to undergo a brutal evolutionary filter. Low-tech crimes are pushed out of the cryptocurrency space, as mentioned in the dialogue, they retreat back into the gift card and cash worlds. What truly remains and upgrades are new participants capable of encoding illegal intentions into complex financial protocol logic. What we are witnessing is not the end of crime, but a fundamental shift in its form from “avoiding surveillance” to “manipulating rules.” When every transaction is exposed to the sunlight, the focus of the game shifts from how to hide to how to construct an indeterminate financial behavior under the watchful eyes of all. The next battlefield will move from blockchain explorers to intelligent systems.

By the end of 2025, the foreign exchange market is experiencing a quiet yet intense asset re-pricing.
In late December, the offshore Chinese yuan (CNH) against the US dollar broke through the 7.0 psychological barrier intraday, reaching a high of 6.99, the highest since Q3 2024. The onshore yuan also dipped to 7.0133 against the dollar.
While the official exchange rate was still battling around the 7.0 mark, the OTC USDT price had already rarely fallen below 6.90 earlier. As of press time, multiple exchanges showed the OTC USDT price (buy 1) at approximately 6.83 yuan, which is a 2.48% USDT negative premium relative to the current exchange rate of 7.0040.

By the end of 2025, news about ByteDance's plan to spend billions on purchasing tens of thousands of top-tier NVIDIA AI chips has become a hot topic in the tech industry. Media perspectives focus on narratives of capital competition and geopolitical considerations. However, behind this billion-dollar procurement order, a much larger and more complex engineering challenge is quietly being overlooked: transforming these chips into usable, efficient, and stable computing power is far more difficult than acquiring them. When the number of chips jumps from hundreds in the laboratory to tens of thousands at an industrial scale, the complexity of system design does not grow linearly but undergoes a qualitative change. The floating-point computing capacity of a single GPU is no longer the bottleneck; how to achieve ultra-high-speed communication between chips, how to supply massive training data with millisecond-level latency, how to efficiently allocate and cool enormous amounts of power, and how to intelligently schedule thousands of computing tasks—these series of system-level problems form an engineering abyss that lies between raw hardware and AI productivity.

The domestic stock market performed poorly, with both the KOSPI and KOSDAQ indices declining. Retail investors had net buy-ins, but foreign and institutional investors both net sold. The Korean won exchange rate and gold prices also declined, and the overall market trend remains weak.

Recently, popular trading pairs on decentralized exchange (Dex) include BlackWhale/SOL, SolARBa/SOL, and icy/SOL. BlackWhale experienced the largest decline within 24 hours, while HNUT/SOL saw an astonishing increase. The total DEX trading volume reached $45.16 billion, with Solana and Ethereum contributing the majority of the trades.

SoftBank Group will acquire DigitalBridge, which focuses on AI infrastructure investments, for $4.04 billion, strengthening its presence in the global digital infrastructure market. This acquisition will help SoftBank move towards its vision of an artificial superintelligence platform and is expected to be completed by 2026.

The cryptocurrency market experienced slight declines amid fluctuations on the morning of December 30. According to TokenPost market data, as of the current benchmark time (05:12 Korea Time), Bitcoin has decreased by 0.26% from the previous day, with a trading price of $87,255.07 (approximately 125 million 9 thousand Korean won). Ethereum has decreased by 0.01% from the previous day, trading at $2,930.36 (approximately 4.2 million Korean won).

The huge foundation supporting the internet world is "Linux." Most servers worldwide run on Linux, and the core of the Android smartphones we use every day is also Linux. However, ordinary users may not even realize they are using Linux. They don't need to know. As long as the network speed is fast and applications run smoothly, that's enough.
The turning point currently facing the cryptocurrency market is precisely this "Linux path." In the past few years, the cryptocurrency industry misjudged the public's willingness to follow their values. They believed that concepts like decentralization, self-sovereign identity, and radical transparency would change the world.
But this assumption is wrong. As previously diagnosed in this publication through editorials, the pain and initial state of the cryptocurrency market integrating into the mainstream financial system are not driven by grand ideals. The public has chosen pure "pragmatism."
Recently, institutions and mainstream applications have introduced crypto into the market.

In December, the technology-driven startup investment market was active, with many companies securing funding. Inito expanded its hormone analysis platform, Assaia optimized airport operations, Aether Bio developed new proteins, Wearlinq enhanced ECG monitoring, and Built AI automated real estate analysis. Their successes demonstrate the potential of technology applications across multiple fields.

Quantum Threats May Emerge Within 15 Years; Without Changing Bitcoin's Block Size, Transitioning to Quantum-Resistant Addresses Would Take 20 Years
— Exclusive Interview with Professor Ding Jintai, Dean of the School of Mathematics and Physics at Xi'an Jiaotong-Liverpool University, a Global Pioneer in Post-Quantum Cryptography
By the end of 2025, quantum computing technology is expected to develop rapidly. The latest report from the German Federal Office for Information Security (BSI) indicates that significant breakthroughs in quantum error correction were achieved in 2024. Conservative estimates suggest that quantum computers capable of cryptography-related calculations could appear within 15 years. This transforms the "quantum threat" faced by Bitcoin and the entire digital financial system from a distant hypothetical to an imminent reality: once large-scale quantum computers mature, the current public key cryptography system will be vulnerable, and all encrypted assets will face the risk of being exposed.

Under the dual pressure of information explosion and trust crisis, the concept of "Staked Media" proposed by a16z acts like a powerful booster shot, attempting to reshape media credibility through blockchain technology and economic games. The core logic of this idea is clear and enticing: media outlets or individuals stake a certain amount of cryptocurrency before publishing content; if the content is falsified, the assets are forfeited; if it is truthful and accurate, the staked assets are returned and possibly rewarded. This model combines economic incentives with fact verification, aiming to build an ecosystem where "telling the truth is more profitable."
However, when we delve into the complexity and social nature of truth production in media, we find that relying solely on smart contract-based staking and on-chain arbitration is far from sufficient to solve the century-old trust issues in media.
