On November 3, according to Businesswire reports, Ripple announced the launch of digital asset spot prime broker services for the US market. U.S. institutional clients can now execute over-the-counter (OTC) spot trades on dozens of mainstream digital assets, including XRP and RLUSD. After acquiring multi-asset prime broker Hidden Road, Ripple integrated its license and Hidden Road's solutions into the Ripple Prime system, providing institutional customers with new capabilities that enable them to seamlessly access foreign exchange (FX), digital assets, derivatives, swap contracts and fixed income products. With this launch, U.S. clients of Ripple’s prime brokerage business can perform cross-margin management of their OTC spot transactions and positions with other assets in their digital asset portfolios. According to The Block, StarkWare has deployed its next-generation open source S-two prover on the Starknet mainnet, calling it the fastest and most privacy-protecting proof system in the world's production environment. This upgrade replaces the original proof component of the network and can now generate validity proofs for each block, shortening proof time, reducing verification costs, and improving throughput and scalability while ensuring trustlessness. In addition, the system also allows independent operators to contribute computing resources, enhancing the network’s censorship resistance. A key feature of S-two is that it can run efficiently on consumer-grade hardware. Users can generate privacy certificates directly through laptops, mobile phones and browsers, without relying on centralized data centers. StarkWare said that this makes large-scale privacy protection a reality, and users can prove facts such as age, qualifications or transaction intentions without revealing sensitive data, while giving rise to new application scenarios, such as private decentralized finance (DeFi), anonymous identity authentication, verifiable AI) and zero-knowledge security games.
