Reflex Aerospace, a German satellite company, is expanding satellite production in Europe with the support of NVIDIA's planned investment.

The U.S. Department of Homeland Security (DHS) instructed U.S. civil agencies on Monday to remove products from the Chinese AI company DeepSeek from government IT systems, as well as any third-party services built on that model, and to prohibit new procurements. The notice stated that using DeepSeek could lead to the transfer of sensitive data to China and could generate intelligence targeting U.S. individuals and institutions. DHS indicated that these models constitute "multiple threat vectors."The ban targets not only DeepSeek's own applications but also covers third-party services based on its development. A DHS memorandum from July was made public on Monday, which had previously requested agencies to monitor the risks related to DeepSeek in the traffic in and out of government websites. The U.S. Department of Commerce, the Navy, and the states of New York, Tennessee, and Virginia had previously restricted DeepSeek. The Federal Communications Commission (FCC) will vote on October 29 to decide whether to ban all Chinese laboratories from testing electronic products used in the U.S.DeepSeek is a startup based in Hangzhou, and its open-source model attracted widespread attention on January 27, 2025, with development costs of less than $5 million, leading to a 16% drop in Nvidia's stock price that day, evaporating about $600 billion in market value. In April 2025, the U.S. House of Representatives' Special Committee on China Issues stated that DeepSeek might secretly send U.S. user data to the Chinese government and may have used about 60,000 Nvidia chips, of which 20,000 were subject to U.S. export controls. The V4-Pro model preview released by DeepSeek in April this year was priced about 98% lower than OpenAI's GPT-5.5 Pro and was made available for free download and modification under the MIT license; this week it also released an updated version of the V4.1-Flash model focused on efficiency optimization.

Apple announced that it will hold a new product launch event in Los Angeles on October 28 at 1 PM Eastern Time.According to technology journalist Gurman, Apple is expected to launch its first touchscreen MacBook Pro, a new Mac equipped with the M6 chip, and an iPad mini with an OLED screen.

Financial technology company Ramp announced that it submitted an application to the Office of the Comptroller of the Currency (OCC) on October 16 to establish Ramp National Trust Bank. If approved, the trust bank license will allow it to provide fiduciary investment management and digital asset custody services, bringing it under a unified federal regulatory framework.In addition, the proposed entity will not engage in accepting deposits or issuing commercial loans.

The Bitcoin infrastructure protocol Echo Protocol announced on platform X that it will gradually terminate the operation of the protocol due to business adjustments. The official announcement expressed gratitude to the community, partners, and users for their long-term trust and support, and committed to completing the subsequent liquidation work transparently and responsibly.Currently, all core businesses of the Echo Protocol have fully stopped accepting incremental funds. The lending protocol has halted new deposits, new loans, and interest accrual, while the strategy and LSD businesses have also ceased new deposits and new pledges.The official has now opened repayment, withdrawal, and necessary asset liquidation channels, urging users to take action as soon as possible: lending users should repay debts, release collateral, and withdraw assets promptly; strategy and LSD users should initiate exits and claims as early as possible; users holding aBTC can continue to use the Aptos-to-B² cross-chain bridge for redemption.To ensure an orderly liquidation process, the announcement specified key timelines. All borrowers with outstanding debts must complete repayments by November 14, 2026, or face collateral liquidation, with the proceeds used to repay lenders. The final deadline for users to make repayments, withdrawals, and release pledges is November 19, 2026, at 23:59 (UTC).After this, the Echo Protocol will officially cease operations, and all remaining positions will enter the final liquidation and settlement process, with the platform only retaining the redemption service of the Aptos-to-B² cross-chain bridge. Since LSD and Strategy assets depend on the request time for underlying pledges/unpledges, the actual time users can claim will be affected by this factor.

According to Cointelegraph, Section 502 of the Digital Asset Tax Clarification Act (H.R. 10357) currently advancing in the U.S. Congress stipulates that the Secretary of the Treasury must establish a voluntary disclosure program for digital assets within 12 months after the act takes effect.Eligible taxpayers can correct past digital asset tax violations by submitting amended returns and paying back taxes, interest, and penalties under the program. The act was passed by the House Ways and Means Committee on September 16 with a vote of 38 to 5, but it has not yet officially become law and still needs to be passed by the House, the Senate, and signed by the President.Andrew Gordon, Executive Director of the Digital Asset Taxation Action Organization, stated that this is a significant change that will help many ordinary taxpayers, yet it has received little attention. He pointed out that U.S. investors are facing the first filing season under the new 1099-DA broker reporting rules, which give the IRS greater visibility into crypto transactions but do not address the years prior to the rules taking effect. Sharon Yip, founder of Crypto Tax Advisors, also noted that filing errors among ordinary crypto investors are very common, and the existing procedures lack standardized processes, making it impossible to provide predictable penalty treatment for unintentional violators.According to Section 502, taxpayers generally must submit amended returns within 24 months after the program is established, and the act sets two penalty standards. Taxpayers who provide proof that their violations are neither fraudulent nor intentional can apply a 0% penalty on the portion of back taxes up to $25,000 if they file within the first 12 months after the program starts, while amounts exceeding that will incur a 5% penalty.Those who do not provide such proof will face penalties of 25% and 40%, and the tax rates will increase if the initial window is missed. The act also provides specific civil penalty waivers, allowing unproven taxpayers to be exempt from criminal referral within the scope of the disclosed information. A report by CoinTracker in 2026 showed that only 49% of crypto users correctly understand that selling crypto assets is a taxable event.

According to the summary from the Arbitrum Foundation governance forum, the Arbitrum DAO currently has 4 temperature check votes ending on October 22, involving the Ethereum Glamsterdam upgrade adaptation, L1 governance recovery mechanism, treasury ETH transfer, and USDG strategic plan.Among them, the Entropy proposal suggests setting USDG as one of the core strategic plans of the Arbitrum DAO and additionally allocating 100 million ARB from the DAO treasury to the DRIP budget, while adjusting the project cycle and allowed uses. Furthermore, it is proposed to direct the net fees from AEP into ATMC and convert them into USDG to support the growth of USDG on Arbitrum.

According to The Defiant, THORChain announced that its v3.21 upgrade will fix the FIN contract vulnerability on Rujira and allow the previously paused application layer to restart. The network has set the upgrade target at block height 28,366,100, with an expected time around October 23. After the restart, trading, lending, borrowing, and automated trading on Rujira will resume. Rujira's products run through smart contracts within THORChain, rather than on an independent blockchain, and the application layer can pause these contracts without affecting the underlying layer of THORChain.According to Rujira, the vulnerability was discovered on September 26, when an attacker transferred a custom concentrated liquidity position without holding a position. The team paused the application layer with the support of node operators, and only one position from the Rujira team itself was affected, with no loss of user funds. Rujira attributed the vulnerability to a flaw in the position transfer function, rather than the trading logic of the liquidity strategy. On September 27, Rujira stated that the fix is located at the underlying layer and has been scheduled for the v3.21 upgrade.Regarding the restart window, Rujira proposed a conditional grace period in its plan on October 15: if the application layer is ready to resume, any credit account position with a loan-to-value ratio above 100% and meeting liquidation conditions will request node operators to pause the credit account contract for an additional 24 hours, allowing borrowers to replenish collateral before liquidation resumes. Borrowers can replenish collateral through Rujira Borrow or by directly transferring assets to the credit account address. Rujira indicated on October 10 that positions still deemed unsafe after the grace period may be liquidated when the liquidator triggers the process.

According to PR Newswire, BitMine increased its holdings by 12,535 Ethereum last week. As of October 18, 2026, its total Ethereum holdings reached 6,041,481, accounting for approximately 4.9% of the total Ethereum supply.Currently, the total value of cryptocurrencies, cash, and other investment assets held by BitMine is approximately $15.1 billion, which includes $582 million in cash and securities, 215 Bitcoin, $180 million in equity assets from Beast Industries, and a $74 million investment in Eightco Holdings (ORBS). Additionally, the number of Ethereum staked remains at 5,067,309 (84% of total holdings), valued at approximately $12 billion, with a current annualized staking yield of about $309 million.Tom Lee, Chairman of BitMine, stated in the company's weekly report that in recent weeks, investor risk appetite has contracted due to concerns over AI financing and AI model security issues, the escalation of the US-Iran conflict, anxiety over the US midterm elections, and a general rise in global bond yields. This has led to a sell-off of AI stocks (including semiconductor and memory chip stocks), further resulting in deleveraging in the Korean and Taiwanese markets, which are dominated by semiconductor and memory chip stocks.He pointed out that crypto assets are widely held in the US, South Korea, and Taiwan, and as investors in these regions reduce their risk exposure, it naturally creates spillover pressure on the crypto market. However, historically, when fundamentals remain robust while prices decline, it often presents an attractive risk-reward opportunity. Given that crypto assets benefit from the modernization of global financial infrastructure and AI intelligence, he believes this time is no exception.

Metaplanet founder and CEO Simon Gerovich announced that the transaction between Metaplanet and Super League Enterprise, Inc. (NASDAQ: SLE) has been formally approved at the company's shareholder meeting.This move marks a key step for Metaplanet in transforming from a Bitcoin treasury company to a global Bitcoin-native financial platform.It is reported that Metaplanet injected 2,100 Bitcoins and $2.5 million in cash into the NASDAQ-listed company Super League Enterprise (SLE), with a total value of approximately $134.6 million, in exchange for a controlling stake. In return, Metaplanet received approximately 44.86 million newly issued shares of common stock (at $3 per share), as well as preferred stock and warrants. After the transaction is completed, Metaplanet will hold about 95.7% of SLE's issued common stock, becoming its controlling shareholder.According to Gerovich, after the transaction is completed, Superplanet will serve as Metaplanet's Bitcoin treasury platform listed in the United States, which will enable it to directly access the U.S. capital markets and gain more agile and flexible financing capabilities. Strategically, combined with Metaplanet Securities established in Japan, this approval will provide the company with complementary platforms in the two most important capital markets globally (the U.S. and Japan).This will not only facilitate its international financing and capital allocation but also further advance its business expansion in areas such as Bitcoin treasury, financial services, financial products, and asset management. Gerovich stated that this is a new milestone on Metaplanet's long-term growth path, and the company will continue to update the public on the latest progress regarding the completion of this transaction.

According to CoinDesk, Cardano founder Charles Hoskinson stated that he is personally developing a new programming language for the Cardano network and collaborating with Input Output Global engineer Lucas Rosa. Lucas Rosa is a co-creator of Aiken, one of Cardano's main smart contract languages. Hoskinson posted on the X platform that this will be the first programming language to combine user transaction completion intentions with cryptographic proofs.It is reported that the language will support three tools: transaction intent, data with carry proofs, and Groth16 proofs. Transaction intent allows users to specify the goals they want to achieve, while leaving the specific steps to the application, for example, traders can request that a token be exchanged for another only when the final price meets certain conditions, without specifying the exact path.Data with carry proofs can attach cryptographic evidence to information, proving that it complies with specific rules, allowing other applications to verify without recalculating. Groth16 is a widely used proof system that can generate small-sized, fast-verifying proofs, demonstrating that conditions have been met without exposing private data.With the combination of the three, developers can build applications that coordinate transactions, check complex conditions, and pass verified information between services, ultimately verified by Cardano with a small proof. Currently, Cardano developers mainly use Haskell-based Plutus and Aiken to write smart contracts, while Input Output Global, founded by Hoskinson, has its own privacy blockchain Midnight with its language Compact. The name, public code, and release date of this new language have not yet been announced.

The Hyperliquid Policy Council (HPC) stated that it has submitted a comment letter to the U.S. SEC in support of its proposed Regulation Crypto Assets and suggested 5 adjustments to the final rules to further clarify the regulatory boundaries regarding token issuance, airdrops, secondary market trading, and safe harbors.

According to Bloomberg, Spencer Applebaum, General Partner and Co-Head of Venture Capital at Multicoin Capital, stated that unlike institutions such as Paradigm, Framework Ventures, and Haun Ventures, which are expanding their investment scope beyond the crypto space, Multicoin will not extend its investment scope to pure AI projects, as its strengths lie in the crypto field, and believes that many investors are "forcing" a search for intersections between crypto and AI.The $422 million venture capital fund raised by Multicoin in 2022 has been deployed slowly due to the decline in valuations of startup projects following the collapse of FTX. Spencer Applebaum also mentioned that HYPE remains the largest position in Multicoin's hedge fund. Currently, Multicoin's assets under management stand at $2.7 billion.

Siemens stated that it is collaborating with NVIDIA to promote the development of AI-driven autonomous factories.

Snapshot posted on platform X, stating that ENS is voting to activate ENSv2 on the Ethereum mainnet through an on-chain proposal that includes 15 calls. This proposal is executed in one go by the execution contract controlled by the ENS DAO, which, if passed, will freeze new registrations of version 1 while allowing un-migrated domain names to continue renewing.After the upgrade, ENSv2 will allow owners to customize the subdomain registry and grant resolution rights individually without transferring domain ownership. In addition, ENS Labs will synchronize eligible domain names, open v2 registrations and migrations, and transfer the remaining management rights to the ENS DAO.

Ethereum research forum researcher Pierre proposed a faster, aggregatable, and quantum-resistant privacy pool solution.This solution ports a Tornado Cash-like privacy pool to the hash-based SNARK system Flock, which may possess post-quantum security, and uses SHA-256. The solution replaces large circuits with small "single compression" circuits.
