Vitalik: The current roadmap of Ethereum adds directions such as enhanced privacy, post-quantum scalability, and native Rollups

Vitalik Buterin stated that he has compared the 2023 Ethereum roadmap with the current Strawmap, and while there is still a high degree of overlap in the overall direction, some priorities and technical paths have been clearly adjusted. This includes elevating the priority of quantum security, downplaying VDF and certain EVM improvements, and replacing old designs with unified binary trees, PBT, new state types, and other solutions.He pointed out that the most significant change in the current Strawmap is the emergence of several new topics not included in the 2023 roadmap, reflecting a shift in the focus of Ethereum's development. These new focal points include: stronger native privacy support, aggressive scaling in a post-quantum context, streamlined specifications for formal verification, Blob and Gas futures, native Rollup, and a more open design space around the future form of EVM.Vitalik also emphasized that Ethereum's scaling approach is shifting from "broadly scaling all activities" to "designing more easily scalable dedicated mechanisms for specific high-load scenarios," and views STARK proofs and AI-accelerated formal verification as important foundations for the protocol's future. Overall, this update indicates that the Ethereum roadmap is evolving towards quantum security, privacy-first, censorship resistance, high performance, and more simplified protocol design.

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.
