Test Abstract

We propose developing a high-performance Rust client library for Ogmios, enabling fast, safe, and efficient communication with the Cardano node. While a TypeScript client currently exists, there's a growing demand for Rust-based infrastructure, especially for backend applications requiring low latency, high throughput, and robust memory safety. The library will support all four Ogmios mini-protocols (chain sync, ledger queries, transaction submission, and mempool monitoring). It will be optimized using advanced techniques such as arena allocation, Struct-of-Arrays optimizations, and SIMD parsing, where appropriate. A complete example application and comprehensive test suite (unit, end-to-end, and live network) will ensure usability and reliability. This project lowers the barrier for Rust developers building on Cardano, improves performance for critical applications (e.g., trading bots, DEXes, mempool tools), and better integrates with Cardano's existing Rust-based serialization ecosystem.

# Three-line summary: 1. Cardano Constitution v2.3 removes non-binding expectations, the Budget Info Action mechanism, and mandatory CC conduct rules, streamlining governance. 2. It adds clear definitions, enforces immutability of proposal documents, and applies treasury audit/accountability safeguards to all withdrawals. 3. Community review of v2.0 had 86.23% DRep participation, and v2.3 incorporates feedback and improvements, addressing prior concerns to reinforce legitimacy and broad input. # Three helpful links 1.
