Galaxy Research: Coldcard attackers continue to transfer funds, approximately 45% of the stolen assets have entered mixing or cross-chain pathways

Galaxy Research published that the attackers in the Coldcard "Wave 3" attack are still continuously transferring the stolen funds. During this phase, the attackers created 293 2-of-2 multi-signature wallets for each victim's assets. The first batch of funds was transferred across chains to Ethereum via THORChain; the latest round of transfers has begun entering the CoinJoin mixing process.Currently, the Wave 3 attackers are processing the largest amounts of stolen funds in order of the stolen amount, having sequentially transferred the funds from wallets ranked 1 to 11. The next 10 wallets that have not yet been transferred hold a total of 30.81 BTC, while wallets ranked 61 to 293 hold a total of 33.77 BTC. So far, the attackers have transferred about 45% of the stolen assets from this exploit, with funds flowing to Ethereum (via THORChain) or entering CoinJoin mixing transactions. Additionally, this fund transfer has revealed a previously unknown wallet: 58 addresses jointly spent in a 2-of-2 multi-signature format identical to that of Wave 3, and these were further transferred by the Wave 3 attackers to a jump address that funds CoinJoin.The on-chain analysis team currently marks this wallet as "cause = open," but believes it likely also belongs to Coldcard victims, which means the number of wallets involved in Wave 3 may increase to 294, raising the previously reported total amount stolen from the Coldcard vulnerability to approximately 1806 BTC. Currently, about 82% of the stolen BTC remains in addresses initially controlled by the attackers, while about 18% has been transferred, with the flow of funds indicating that it may be undergoing laundering processes.

Harmony plans to shut down the mainnet and migrate ONE to Ethereum, shifting towards AI video remixing business

Harmony has released two proposals to comprehensively shut down the mainnet launched in 2019, migrate the native token ONE to Ethereum, and shift towards an AI video "mashup economy" business. The team stated that the threats posed by national-level attackers and AI entities are the reasons for proposing the network shutdown plan.The migration plan proposes to take a snapshot of user wallets, staking delegations, validator rewards, smart contracts, and tokens within centralized exchanges at the last block of the network, airdropping new ONE to the same wallet addresses on Ethereum, with holders not needing to actively claim; delegated stakes and unclaimed rewards will be airdropped to their respective governance vaults. The total supply of ONE and the issuance rate will remain unchanged, with newly issued tokens intended for the new business and feedback from governors being considered.Multi-signature wallets, liquidity pools, and on-chain applications cannot be migrated. The team urges users to exit all smart contracts by September 10, 2026, and plans to publicly disclose token contracts, snapshot calculations, and airdrop scripts for auditing. Validators can stop running nodes starting from September 10 at 22:00 Beijing time. The team plans to compensate for the difference in issuance rewards between node shutdown and the final block of the network, establishing a one-time compensation pool of $1.372 million, to be paid in four quarters to validators and their delegators who timely shut down, sign agreements, retain stakes, and serve as governors of the new project.The new business will open up prompts and materials for users to create secondary content, with AI entities expanding video stories, and will recruit operators responsible for video generation, distribution, and content review. Harmony plans to subsidize GPU hardware in the first year and promote demand for video generation, with operators required to stake tokens to earn rewards based on service online time. The team plans to help operators generate up to $1 million in total revenue in the first year, provided they meet staking and online rate requirements; promoters can initially earn a 30% ongoing commission from each $10 monthly subscription they recommend. Both proposals are non-binding and the plans may still be adjusted.

Changxin Technology's revenue in the first half of the year was 150.31 billion yuan, a year-on-year increase of 873.64%

Changxin Technology released its 2026 semi-annual report, with revenue of 150.31 billion yuan in the first half of the year, a year-on-year increase of 873.64%; net profit attributable to shareholders was 77.61 billion yuan, compared to a loss of 2.33 billion yuan in the same period last year; net cash flow from operating activities was 131.16 billion yuan, a year-on-year increase of 2985.64%; gross profit margin was 84.84%, and R&D investment was 6.859 billion yuan, accounting for 4.56% of revenue. As of the end of the reporting period, total assets were 468.078 billion yuan, and net assets were 270.749 billion yuan.The company is the fourth largest DRAM IDM manufacturer globally and the largest in China, with products covering DDR5, LPDDR5/5X, LPDDR6, etc. It has collaborated with leading clients such as Alibaba Cloud, ByteDance, Tencent, Lenovo, Xiaomi, OPPO, and vivo, and the fifth-generation process technology platform is undergoing customer certification. As of June 30, the company held a total of 4,484 domestic patents and 3,400 foreign patents, with 7,491 R&D personnel, accounting for 33.42%. The company has no controlling shareholder or actual controller, with the largest shareholder, Qinghui Jidian, holding 21.67%. The company was listed on the Sci-Tech Innovation Board on July 27, with an issue price of 8.66 yuan per share, and its market value exceeded 3.5 trillion yuan on the first day of trading.

According to DIGITIMES, Changxin Memory and Yangtze Memory continue to expand, and recently Apple is actively seeking to introduce the two Chinese memory supply chains, drawing attention to their entry into Apple's supply system. Industry insiders reveal that the two manufacturers are actually using Apple to prove that the quality of Chinese DRAM and NAND Flash has reached international standards, while secretly expanding their cloud and enterprise market share through third-party assembly for export to North American neocloud operators.Changxin Memory's parent company, Changxin Technology, has completed fundraising of 29.5 billion yuan, while Yangtze Memory plans to raise about 33 billion yuan through an IPO for production line upgrades and R&D. Yangtze Memory has turned profitable in 2024, with a net profit attributable to the parent company reaching 33.379 billion yuan in the first quarter of 2026; its third-phase new factory will begin production ahead of schedule in the fourth quarter of 2026, with a total monthly production capacity of 100,000 wafers, of which about 20% will be trial-produced LPDDR, becoming its first DRAM base. The supply chain indicates that the two companies are expected to increase the self-sufficiency rate of domestic memory in China to over 50% by the end of 2027 to 2028.Yangtze Memory sells NAND to third-party module manufacturers and assembles them into enterprise-level SSDs to avoid location sensitivity; Changxin Memory has already obtained certifications from small and medium-sized cloud operators in the U.S., Canada, and other regions. U.S. private enterprises can, in principle, procure from the two companies, with the entity list primarily restricting their access to U.S. technology, but not completely prohibiting private procurement. Cloud operators also reduce compliance risks through methods such as renting computing power or holding assets through third parties. The industry believes that Apple's influence on supply and demand in the industry is declining, and the two companies have no intention of supplying Apple in large quantities or engaging in price competition, making it difficult to meet Apple's demand in the Chinese market in the short term.

Vitalik releases research on "local mixing" cryptography: exploring next-generation obfuscation techniques, which may become a new foundational primitive in cryptography

Ethereum co-founder Vitalik Buterin published a new article titled "Obfuscation (Part 3): Local Mixing," which delves into a cryptographic obfuscation technique being explored—"Local Mixing." He claims it may become a new foundational cryptographic tool following elliptic curves, RSA, and lattice-based cryptography.Vitalik states that current mainstream obfuscation techniques mainly rely on complex mathematical assumptions, often resulting in extremely high computational overhead. In contrast, Local Mixing adopts a completely different approach, not relying on elliptic curves, large integer factorization, or lattice cryptography. Instead, it draws on experiences from symmetric cryptography and hash function design, continuously shuffling, reconstructing, and hiding circuit structures to eliminate information leakage while maintaining functionality.The Local Mixing technique primarily includes steps such as reversibility, hardening, mixing, splitting, crossing walk, and "gadgetization." By introducing random structures into the circuit, rearranging logic gates, and employing nonlinear hiding mechanisms, it makes it difficult for attackers to recover the original computational logic.Vitalik points out that this technology is still in its early stages, with security not yet validated over the long term and facing challenges such as random attacks and linear analysis. However, he believes that Local Mixing represents a completely new path for cryptographic exploration, aiming to construct more efficient indistinguishable obfuscation (iO) schemes.If breakthroughs in Local Mixing technology are achieved, it could lead to new quantum-resistant public key encryption schemes and promote the development of general obfuscation techniques. The field still requires years of cryptanalysis and optimization validation, but AI-assisted research may significantly accelerate this maturation process. Vitalik states that obfuscation technology is seen as the "final frontier" of cryptography because, theoretically, other cryptographic primitives can be constructed based on obfuscation and one-way functions. Local Mixing may not only reduce the costs of traditional obfuscation schemes but could also become an important direction for future cryptographic infrastructure.
