Odaily News Polyhedra and Berkeley RDI have launched the first zero-knowledge proof system that can verify large language models (LLMs). Just as HTTPS has established security for Internet communications, this system has built a verification infrastructure for the field of AI. The system can efficiently verify AI performance and compliance without exposing models or data, and is 20,000 times faster than previous methods. Currently, large language models including Llama 3-8B can be quickly verified. The key highlights are as follows: - Polyhedra&#39;s innovative technology: Zero-knowledge machine learning (zkML) technology is like the HTTPS protocol on the Internet, which allows the performance and compliance of AI systems to be verified without leaking model or data details, protecting privacy and security. - Excellent performance: Expander greatly improves verification efficiency, and the single-threaded verification speed is 20,000 times faster than existing methods, supporting VGG-16 per image 2.2 seconds and Llama-3 per token 150 seconds. - Developer-friendly: The zkPyTorch compiler seamlessly integrates PyTorch to provide developers with simple and easy-to-use tools. Application scenarios: - AI service quality assurance - AI training data compliance - Fair data automatic trading market - AI Agent responsibility allocation - AI Agent compliance - Financial services compliance verification This system not only solves the compliance problems in AI model verification, but also provides a new solution for AI security and credibility.

Odaily News Aleo has announced the details of its incentive program, which aims to reward community members who participate in the development of zero-knowledge technology applications. Incentive distribution targets include ambassador programs, testnets, zkML incentives, etc. The application process requires participants to complete KYC verification, agree to the terms and comply with the token lock-up regulations. US residents are subject to a one-year lock-up period.

Odaily News Polyhedra announced the latest development roadmap of Expander. After zkBridge achieves trustless interoperability, Polyhedra will further promote the development of zkVM and zkML. Through distributed computing, GPU and hardware implementation, Expander will take performance to a new level, greatly improving the speed and efficiency of proof generation. In addition, Expander&#39;s roadmap highlights the characteristics of complex circuit compilers and efficient witness generation, integrating Proof Cloud to provide full-stack ZK proof services. In the roadmap, DExpander will bring an additional 100 times acceleration to Expander through distributed computing in the future. Polyhedra also demonstrated the completion of the ZK proof of Ethereum&#39;s full consensus within 10 seconds through distributed proofs, opening up the possibility of Ethereum SSF (Single Slot Finality). Single Slot Finality is the next important milestone of Ethereum that the Ethereum community, including Ethereum founder Vitalik Buterin, has long been committed to achieving, and it is of great significance to Ethereum consensus technology. Expander has brought an important breakthrough to the realization of this milestone.

Odaily News Polyhedra Network has open-sourced the zero-knowledge proof system Expander, which supports large-scale parallel computing. Expander will soon support zkVM and zkML, and will be available on the Proof Cloud service. Expander supports ARM Neon and AVX instruction sets and performs well on the M3 Max CPU. This high-performance performance is due to its core technology of GKR-based prover and polynomial commitment based on expander code. Its efficient, secure, and low-cost features, as well as support for AI Layer1 and mobile AI distributed computing, are expected to open up new application scenarios.

Odaily News Polyhedra Network today launched a new open source ZK proof system Expander, which breaks the existing world record for generation speed and provides the infrastructure for the implementation of ZKVM and ZKML. Expander enables projects of any size to process data efficiently, securely, and at low cost. At the same time, it provides strong support for the implementation of AI Layer1, and allows users to use mobile phones to support AI distributed computing power, promote the deep integration of AI and blockchain technology, open up new application scenarios, and is expected to create a new market with a trillion value.

Odaily News Polyhedra Network released a video on the X platform to introduce the projects current achievements and future vision. It mentioned that its engineering team has developed multiple protocols, including Libra, Virgo, deVirgo, Pianist, Marlin, Gemini and Orion. These protocols greatly increase the speed of proof while keeping the proof size and verification cost unchanged. In addition, Polyhedra collaborates with projects such as zkEVM, zkML, ZKID for secure authentication, ZKP solutions in the financial sector, zkOracle, etc. to make these solutions more practical and efficient. The Polyhedra base layer includes zkCompiler and PWS (Proof Generation Service). zkCompiler simplifies the process of writing high-performance ZK proof circuits, while PWS allows developers to deploy their ZK circuits or code onto their infrastructure. Polyhedras flagship project zkBridge has seamlessly integrated with more than 25 mainstream blockchain networks and processed more than 18 million transactions. Polyhedra is working to introduce zero-knowledge proof technology to Bitcoin to enable smart contract functions and high-speed cross-chain bridging. This will further expand the application scenarios of zkBridge and provide more possibilities for the interoperability of the blockchain ecosystem.
