first_img Paradigm co-founder disclosed investment in ZEC, Zcash rose about 20% in 24 hours

Privacy token Zcash (ZEC) rose about 20% in 24 hours, with Paradigm co-founder Matt Huang revealing that the company has invested in ZEC. ZEC supports shielded transactions that hide addresses and transaction amounts using zero-knowledge proofs, with a price of about $1,338 on Thursday.Huang disclosed in a post that Paradigm is both an investor in the Zcash Open Development Lab (ZODL) and a holder of ZEC tokens. He described Zcash as "a privacy complement to Bitcoin" and supports its developer fund backed by inflationary funds, believing that long-term funding support remains important in the context of AI network capabilities and the development of quantum computing. He also supports combining Zcash token voting with other forms of governance to reduce its unpredictability as a monetary asset.Today's increase of over 10% has led to a cumulative rise of about 160% for ZEC over the past month, while Bitcoin has risen 18.2% during the same period. Paradigm's investment in the Zcash ecosystem has been publicly disclosed, with ZODL announcing the completion of over $25 million in seed funding in March, with participants including Paradigm, a16z crypto, Coinbase Ventures, and Winklevoss Capital. As ZEC rises, the Federal Reserve raised interest rates by 25 basis points to 3.75%-4%, marking the first rate hike of 2023, with the overall cryptocurrency market trending upward.

first_img Stanford professor releases venture capital firm rankings: 5% of VCs generate 90% of industry profits, 21 new firms enter the top 100

Stanford Business School Professor Ilya Strebulaev, in collaboration with Blake Jackson, released the 2026 Strebulaev-Jackson Venture Capital Firm Rankings, based on nearly 30 years of data from over 230,000 investments and nearly 13,000 VCs. The research estimates that about 5% of VCs generate approximately 90% of the industry's profits. The top five are Sequoia Capital (10,158 points), Andreessen Horowitz (8,292 points), Accel, DST Global, and Tiger Global. Among them, Parkway Venture Capital (19th place) and Notable (20th place) made it into the top 20, but are not well-known leading brands.The rankings are based on six major factors: discount valuation, dilution adjustment, net profit (after costs), value added (lead investments and board seats), human capital decay (three-and-a-half-year half-life), and credit allocation between institutions and individuals (25% for the investing institution and 75% for the current institution). Of the top 100, 62 are located in California, 19 in New York, and 6 each in Massachusetts and Texas. 21 were established in 2015 or later, and 23 of the best investments are in frontier AI or AI infrastructure companies, with OpenAI listed as the best investment by 4 firms, xAI by 3, and Anthropic and Perplexity by 2 each. The ranking methodology has a correlation of only about 0.27 with the Midas List, with SV Angel investing in about 139 unicorns ranked 31st, and Thrive with only 47 unicorns ranked 8th. This ranking is the result of research by Stanford professors and does not constitute investment advice.

Vitalik: The Diamond iO exploration program "stealth" new paradigm may drive privacy computing into a new stage

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.
