Ethereum co-founder Vitalik Buterin published a new article introducing a novel cryptographic obfuscation technology called Diamond iO. This technology aims to address the extremely low efficiency of traditional indistinguishable obfuscation schemes, allowing programs to run while hiding internal logic and critical data. Although traditional iO technology possesses strong privacy protection capabilities, its operational costs are prohibitively high, making it nearly impractical. Diamond iO, by adopting more aggressive new cryptographic assumptions, enhances computational efficiency from "universe-level time consumption" to "planet-level time consumption," bringing it closer to practical application.Diamond iO is built on technologies such as Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE). By encrypting programs, it allows users to execute the encrypted programs and obtain correct outputs without being able to view the internal code or hidden keys. This solution introduces a new input encoding mechanism and conditional decryption method, reducing computational complexity while ensuring the program logic remains hidden. Its core application scenarios include protecting programs that contain private keys, enabling secure software licensing, constructing trustless cryptographic services, and supporting blockchain and artificial intelligence systems with stronger privacy protection.However, Diamond iO is still in the early research stage, and its security relies on new cryptographic assumptions, including All-Product LWE and Evasive LWE, which require further research validation. At the same time, the technology still faces efficiency challenges such as high computational overhead and circuit depth limitations. Researchers believe that by optimizing underlying hash functions, improving homomorphic encryption schemes, and reducing security parameter requirements, Diamond iO is expected to become an important direction for advancing practical program obfuscation technology in the future.

CryptoQuant data shows that the fund flow of USDC on exchanges has shifted back to net inflow after experiencing over two months of net outflow.This change may indicate that the purchasing power of U.S. funds is re-entering the cryptocurrency market.

SK Hynix's leader, Choi Tae-won, stated that South Korea must become an "AI-native country," adding, "The goal is for everyone to have at least one AI agent." He said, "If this goal is achieved, South Korea will become a global AI testing ground, allowing various AI technologies to be experimented with and applied here."Choi Tae-won mentioned that SK Group will provide more opportunities for AI development through continuous R&D investment. He also emphasized that reducing AI costs is crucial. He stated, "Currently, AI costs are too high." "We must find various ways to lower costs so that more people around the world can enjoy the benefits brought by AI."Choi Tae-won indicated that South Korea can lower AI costs by expanding the production scale of memory chips and building more AI data centers, creating a global AI data center hub that connects the United States, Europe, and Asia.

According to monitoring by Lookonchain, a giant whale obtained 557,902 HYPE (worth 32.87 million USD) from FalconX and deposited it into Hyperliquid for staking.

Coinbase is undergoing the largest executive reshuffle in recent years. Chief Talent Officer Lawrence Brock has stepped down and transitioned to an advisory role, while co-head of the institutional division Greg Tusar has moved to a policy position; previously, General Counsel Paul Grewal planned to leave, and Jesse Pollak has stepped down as head of the Base app. After laying off 14% of its workforce in May, Coinbase is accelerating its transformation into a comprehensive trading platform that includes stocks and prediction markets.

According to Onchain Lens monitoring, a certain whale transferred a total of 8,000 ETH to Binance, worth approximately 15.1 million USD. The wallet had held the related funds for about 8 months.

According to BBX data, yesterday and in recent days, global companies listed on the US stock market have disclosed the latest real announcements regarding digital asset transformation and ecological strategic investments. The core dynamics are as follows:Canton sells traditional business to fully transition to blockchain clearing: Canton Strategic Holdings, Inc. (NASDAQ: $ CNTN) officially announced that it has sold its biotechnology R&D department Gravitas Life Sciences, LLC to Gravitas Collective Corp. The transaction was completed on July 17, 2026. The company clearly stated that this divestiture is an important milestone in its transformation into an operating company, and in the future, it will support the Canton Network through Canton Coin and promote the on-chain digital transformation of traditional financial markets as a strategic investor.Empery Digital invests $20 million in cross-industry computing power electricity park: The US-listed company Empery Digital Inc. (NASDAQ: $ EMPD), which adopts a Bitcoin fund management strategy, announced that it has completed a $20 million preferred stock investment (holding approximately 8%) in Cardinal Data Power, Inc. (CDP) on July 20, 2026. CDP focuses on building electricity-driven data center parks, and this round of financing will support its construction of the first gigawatt-level data center park covering over 3,000 acres in West Texas (Phase I is planned to be operational in 2027, with a long-term plan exceeding 5GW) to meet the next generation of AI and computing power energy demands.

According to South Korean media Daum, data from the Korea Exchange shows that from July 20 to 23, foreign investors net purchased the South Korean stock market for four consecutive trading days, with a total net purchase of 55.74 trillion won, marking the first consecutive four-day net inflow since April. Among them, Samsung Electronics and SK Hynix became the main recipients of funds, with net purchases of 17.3 trillion won and 27.6 trillion won, respectively, totaling 44.8 trillion won, accounting for over 80% of the total net purchases by foreign investors during the same period. The market believes that tech giants like Google continue to raise their AI capital expenditure expectations, improving the demand outlook for HBM and server DRAM, coupled with the increased attractiveness of the two companies after prior valuation adjustments, driving foreign investment to focus on leading South Korean memory chip manufacturers.

According to Onchain Lens monitoring, Chun Wang (@satofishi) deposited $15.65 million in assets into Binance, including 6,009 ETH, worth approximately $11.56 million, and 62.31 WBTC, worth approximately $4.09 million.The sources of the related assets include withdrawals from Spark Fi, unstaking from Lido Finance, and exchanging WETH for WBTC through CoWSwap.

According to analysis by XWIN Japan, CryptoQuant data shows that although there are occasional spikes in daily Bitcoin deposits, Binance's 30-day net flow tends to balance out, with withdrawals essentially offsetting deposits. This means that large deposits have not translated into sustained net inflows of funds—incoming BTC is either absorbed by market buying or withdrawn for long-term custody.Analysts point out that neutral or negative net flows typically reflect holding behavior rather than a willingness to sell. Current data suggests that investors may be more inclined to use Binance for liquidity rather than preparing for large-scale sell-offs. Although short-term spikes in deposits may still lead to price volatility, the overall picture does not indicate sustained selling pressure.

According to on-chain analysts, on June 25, a whale suspected of reducing positions for the first time withdrew 17,675 ETH (28,580,000 USD) from Binance at an average price of 1,617 USD.4 minutes ago, it deposited 3,000 ETH (5.8 million USD) into Binance, with a deposit price of 1,933.91 USD, which would yield a profit of 950,000 USD if sold.
