According to The Block, Ethereum researchers demonstrated a proof of concept for "native Rollups" based on the execution client Ethrex, implementing EIP-8079 through the addition of an EXECUTE precompile, which directly replays and verifies Layer 2 block state changes on the Ethereum base layer.This solution does not rely on zero-knowledge proofs or fraud proofs, but instead is executed and confirmed by Ethereum itself to validate Rollup transaction validity. The related contracts are used to track Rollup state, bridge cross-layer messages, and verify withdrawals based on Merkle-Patricia proofs. Developers claim that native Rollups can simplify long-term maintenance of Layer 2, allowing them to directly inherit Ethereum's security and upgrade properties, and they are still in the exploration and proof of concept stage.

Cryptanalysis provider CoinMetrics senior researcher Tanay Ved expects Coinbase's total revenue for the fourth quarter of 2025 to be $1.77 billion, a 5% decrease from $1.87 billion in the third quarter, as declines in trading volume and asset prices offset growth in derivatives trading and USDC.Trading revenue is expected to be $978 million (a 6% quarter-over-quarter decline), with Deribit's contribution throughout the quarter driving growth in institutional business.Subscription and services revenue remains resilient at $723 million, with the growth in USDC supply offsetting the impact of the Federal Reserve's interest rate cuts and reduced staking rewards.The firm forecasts Coinbase's total revenue for the fiscal year 2025 to be approximately $7.2 billion, reflecting Coinbase's ongoing revenue diversification and strategic expansion into the derivatives space.It is reported that Coinbase will announce its fourth quarter and full-year financial results for 2025 after the market closes on February 12 (Wednesday).

Ethereum researcher Thomas Thiery (also known as soispoke) proposed FOCIL as a core anti-censorship feature in the Hegota upgrade. Hegota is Ethereum's second major upgrade scheduled for the second half of 2026. FOCIL is a protocol layer mechanism that modifies Ethereum's fork choice rules to enforce the inclusion of any valid transaction in on-chain blocks within a limited time.The main goal of this proposal is to reduce Ethereum's reliance on centralized validators to mitigate the potential risk of large-scale transaction censorship in the future, thereby enhancing Ethereum's core value as a neutral, censorship-resistant blockchain. An Ethereum researcher stated, "Without FOCIL, the protocol would be vulnerable to large-scale censorship events. Ethereum should proactively design for long-term resilience rather than reactively respond to sudden censorship."

According to Cointelegraph, cybersecurity researcher Jeremiah Fowler discovered a public database containing approximately 149 million usernames and passwords, which were collected from infected personal devices through information-stealing malware. The database includes account information related to multiple major platforms, with at least 420,000 login credentials associated with Binance users.Experts emphasize that this is not a breach of Binance's systems, but rather the extraction of saved login information from infected devices via "information-stealing" malware. This malware disguises itself as game cheating tools or modifiers, specifically targeting cryptocurrency wallets and browser extensions, affecting over 100 browsers and at least 80 cryptocurrency exchanges, including Binance, Coinbase, Crypto.com, and MetaMask.

The recent surge in Ethereum network activity may be related to address poisoning attacks utilizing low Gas fees. The number of new addresses has reached 2.7 million, which is 170% higher than normal levels, with a daily transaction volume exceeding 2.5 million. The Fusaka network upgrade has reduced transaction fees by over 60%, leading to a decrease in the cost of such large-scale spam attacks. Currently, 3.8 million addresses have received such dust assets in their first transaction, accounting for 67% of the new addresses. So far, 116 victims have lost over $740,000 as a result.

According to DL News, Blockstream researchers Mikhail Kudinov and Jonas Nick proposed in a revised paper published on December 5 that hash-based signature technology could be a key solution to protect the $1.8 trillion Bitcoin blockchain from the threat of quantum computers.The researchers believe that hash-based signatures are a compelling post-quantum solution because their security relies entirely on mechanisms similar to the hash function assumptions already present in Bitcoin's design. This scheme has undergone extensive cryptanalysis during the post-quantum standardization process at the National Institute of Standards and Technology (NIST), enhancing the credibility of its robustness.It is estimated that older Pay-To-Public-Key Bitcoin wallets created before 2012 (including Satoshi Nakamoto's holdings worth $98 billion) contain about $600 billion in Bitcoin, and these wallets will be the first to face the threat of quantum computers.

The Donjon research team at Ledger demonstrated that electromagnetic fault injection (EMFI) can completely compromise a commonly used MediaTek smartphone chip, which is utilized in many Android phone models. The issue requires attackers to have physical access to the device, but it highlights the risks faced by users storing private keys on smartphones.Ledger stated that its team studied the MediaTek Dimensity 7300 (MT6878) chip produced by TSMC. Researchers used EMFI tools to disrupt the chip's boot read-only memory (boot ROM), successfully bypassing core security checks and gaining full control of the chip, allowing it to run arbitrary code at the highest privilege level (EL3). Ledger emphasized that this finding does not affect Ledger hardware wallets.Ledger disclosed this vulnerability to MediaTek in May. MediaTek responded that EMFI attacks are beyond the security scope of the MT6878 chip, which is designed for consumer products rather than financial or hardware security module applications. Additionally, MediaTek stated that devices with higher security requirements, such as cryptographic hardware wallets, should include specialized defensive measures.At the time of the report's release, physical attack incidents targeting cryptocurrency users were on the rise.

ChainCatcher news, according to Cointelegraph, the Korean National Tax Service is intensifying its crackdown on tax evasion, warning that cryptocurrency assets stored in cold wallets may also be seized.Officials stated that if there is suspicion that tax evaders are hiding cryptocurrency assets offline, they will conduct home searches and confiscate hard drives and cold wallet devices. Under the National Tax Collection Act, the National Tax Service can request local exchanges to provide account information, freeze accounts, and liquidate assets to offset taxes. While cold wallets can ensure the security of cryptocurrency assets, they may also be used to hide assets, increasing the difficulty of tax administration. As of June, there were nearly 11 million cryptocurrency investors in the country, an increase of nearly 800% compared to 2020; during the same period, trading volume rose from 1 trillion won (approximately 730 million USD) to 6.4 trillion won (approximately 4.7 billion USD). The popularity of cryptocurrencies has led to an increase in tax evasion cases, with the first action in 2021 seizing approximately 50 million USD in cryptocurrency, and over the past four years, 108 million USD has been seized and liquidated.

ChainCatcher news, the crypto venture capital firm Archetype announced the raising of $100 million for its third fund, which will focus on supporting early seed round financing for blockchain companies.It is reported that Archetype raised its first fund of $55 million in 2021, followed by a second fund of $155 million in 2022, during the peak of the last cryptocurrency bull market. Although Archetype's third fund is smaller, at only $100 million, Egan stated that choosing the right supporters (i.e., limited partners) was a well-considered decision, and only one new LP was brought in.

ChainCatcher news, Greeks.live macro researcher Adam posted on the X platform that ETH briefly fell below $4000 during a significant drop, with multiple technical support levels being breached.After the plunge, the implied volatility of major contracts remained the same as before, but the skew significantly favored put options, with put contract prices noticeably higher than call options, indicating a sharp increase in market concerns about downside risks. There was no significant increase in options trading volume, and market makers' positions entered the gamma amplification range, with some market makers having bought put options to hedge risks. Adam pointed out that if the $4000 level is lost, the options market may face a bear market pricing reassessment; BTC's trend is relatively more stable, but ETH's technical indicators are more critical.
