TD Securities: U.S. Dollar Likely to Decline If Federal Reserve Holds Interest Rates Steady

According to market data from BIT (bit.com), Bitcoin mining firm Ionic Digital’s share price rose 4% on its Nasdaq debut, lifting its market capitalization to approximately $2.332 billion.

Ethereum co-founder Vitalik Buterin has released a new paper introducing the novel cryptographic obfuscation technology Diamond iO. Designed to address the extremely low efficiency of traditional indistinguishability obfuscation schemes, the technique enables programs to run while hiding their internal logic and critical data. While traditional iO offers robust privacy protection, its operational cost is so high it is nearly impractical. Diamond iO, however, leverages more aggressive new cryptographic assumptions to boost computational efficiency from "cosmic-scale time" to "planetary-scale time", bringing it closer to real-world applications. Built on technologies including Attribute-Based Encryption (ABE) and Fully Homomorphic Encryption (FHE), Diamond iO encrypts programs such that users can run the encrypted programs and obtain correct outputs without accessing their internal code or hidden keys. It introduces new input encoding mechanisms and conditional decryption methods, reducing computational complexity while keeping program logic hidden. Its core application scenarios include protecting programs containing private keys, enabling secure software licensing, building trustless cryptographic services, and supporting blockchain and AI systems with stronger privacy protections. However, Diamond iO remains in the early stages of research. Its security relies on new cryptographic assumptions such as All-Product LWE and Evasive LWE, and requires further research for validation. Additionally, the technology still faces efficiency challenges including high computational overhead and circuit depth limitations. Researchers note that by optimizing underlying hash functions, improving homomorphic encryption schemes, and lowering security parameter requirements, Diamond iO is poised to become a key direction in advancing practical program obfuscation technology in the future.

Vida, founder of Formula News, stated on social media that he sold nearly $7 million worth of put options on storage-related stocks today, with most of the contracts set to expire in one month. The current sell-off in the storage sector has at least neared the limit of market sentiment; all top traders are lamenting that they never anticipated such a market move, and the implied volatility of storage stocks is at the historical 100th percentile. The AI revolution remains ongoing, demand persists, and the fundamentals from a month ago have not shifted—this amounts to the same asset trading at a 35-50% discount compared to its price one month prior.

According to Bitget's market data, Brent crude oil has fallen 4.5% intraday, currently trading at $81.98 per barrel; WTI crude oil is down more than 3%, at $78.6 per barrel.

According to official announcements, Base Build has launched Base Verify Onchain, a tool designed to address Sybil attack issues in blockchain ecosystems. The feature is now live on the Base Sepolia testnet, allowing developers to implement the "one real user, one claim" rule in smart contracts. Base Build noted that traditional airdrop mechanisms are vulnerable to manipulation by bulk wallets, with large rewards often going to professional airdrop farmers while genuine users contributing to product development only receive limited benefits. Base Verify Onchain generates a stable identity hash for each real user, enabling projects to identify multiple wallets controlled by the same user without accessing sensitive personal data such as names or account information. Users can complete verification via existing accounts on platforms including Coinbase, Instagram, X, and TikTok; the system then returns verified identity credentials to smart contracts, which automatically enforce rules such as claim limits, voting restrictions, or quota controls. To date, Base Verify has been used over 300,000 times, supporting partner projects including Base App, Cody, Scratch, and Bracket. Base Build stated that Verify Onchain will enable decentralized applications (dApps) to implement fairer airdrops, token distributions, governance voting, and user incentive programs. Developers can leverage this technology to limit claim counts per real user, allocate rewards based on verified identities, or translate real-world signals into on-chain reputation, thereby reducing the impact of bots and multi-wallet manipulation on the fairness of Web3 applications.
