Primus

Primus

Primus is a Web3-oriented privacy data infrastructure project that combines zkTLS and fully homomorphic encryption (FHE) to make off-chain data verifiable, computable, and interoperable across parties without revealing the original information. The project focuses on long-term problems such as the difficulty of verifying the authenticity of off-chain data in on-chain systems and users' lack of control over their own data in existing data systems. By funding Primus, GCC hopes to support it in providing open-source FHE learning and onboarding materials for Chinese-speaking developers and learners, while continuously advancing technical and performance optimization and leading FHE development in the Chinese-speaking community.

SnarkExpress

SnarkExpress

SnarkExpress is an open-source academic aggregation platform focused on cutting-edge zkSNARKs research. It continuously updates important papers in the zero-knowledge field in native LaTeX-PDF form, covering IACR ePrint, special issues of top international conferences, and periodic research compilations. The platform systematically organizes zkSNARKs research progress to form a relatively stable, continuously updated index and reading portal. In terms of functionality, SnarkExpress provides each paper with a structured abstract, a direct link to the original, and reusable .tex/.bib citation files, making it easy for researchers to read, cite, and build on the work. The platform continues and expands ZK Punk's efforts in paper curation, providing a long-term maintained academic reference resource for zero-knowledge researchers and developers.

Vyper

Vyper

Vyper is the second-largest EVM smart contract programming language after Solidity, securing over USD 4 billion TVL across major DeFi protocols such as Curve, Lido, Aerodrome, and Yearn. Compared with Solidity, it has more built-in security protections and constraints at the language level, such as reentrancy locks, a strict type system, and a simpler syntax, and it is more suitable for Web2 developers transitioning from Python. GCC's donation to Vyper will mainly support the development of the Chinese-speaking community, systematically building a Vyper developer ecosystem through "online co-learning camps + offline roadshow events + community content system."

OSKey

OSKey

OSKey is a fully open-source, non-commercial hardware wallet project that helps everyone create and use trustless, general-purpose hardware wallets. Users can freely choose from thousands of third-party development boards and flash the OSKey firmware to use them as hardware wallets. GCC's support is OSKey's first large donation, which will help OSKey reach a user experience comparable to commercial hardware wallets within a year and provide a foundation for its long-term development over the next ten years.

ZK Punk

ZK Punk

ZKPunk is a community co-created weekly digest of ZKP technologies and papers, helping the community stay up to date with the latest academic and industry developments. Contributors add links and descriptions of the latest ZKP technologies and paper updates through the GitHub repo; after aggregation, the website is updated automatically to publish each new issue, and rewards are distributed according to contribution. Running steadily since January 2024, it has accumulated into a high-quality Chinese-language ZK knowledge base.

Liber3

Liber3

Liber3 is a decentralized digital library built on Ethereum using ENS and IPFS technologies, emerging after zLibrary's closure. As one of the largest platforms in the ENS ecosystem with 34% of total traffic, it has enabled the community to mint over 2,800 permanent book records through ENS subdomains. With support from GCC, the project advances toward an uncensorable library with smart contract-based full-text search capabilities and cross-chain integration with Linea.
