Samsung Electronics announced a record 2,655 trillion won ($2.1 trillion) investment over the next five years, focusing on semiconductor manufacturing, AI computing data centers, and high-bandwidth memory (HBM). The plan represents a 30% increase from the previous five-year commitment, driven by surging global demand for AI infrastructure. Samsung will expand advanced process fabs in South Korea and the U.S., and intensify R&D on sub-3nm nodes. The move could indirectly impact cryptocurrency mining chip supply chains and the AI-driven HPC market.
Ethereum founder Vitalik Buterin published a comprehensive post detailing the entire technical tree behind the indistinguishability obfuscation (iO) research thread. The article covers iO's theoretical foundations—multilinear pairings, lattice cryptography—and traces recent breakthroughs in practical iO constructions, including optimizations based on GRW16, GGH+ and others. Vitalik highlights iO's potential applications in universal verifiable computation and post-quantum security, stressing its fundamental importance for blockchain privacy and censorship resistance.
