# deltamesh-federated-privacy-preserving-c This repository contains an initial skeleton for DeltaMesh, a federated, privacy-preserving cross-venue options market-making engine. The MVP components here are intentionally small and self-contained to enable iterative integration with more complete adapters and governance tooling. MVP snapshot - LocalMarket, SharedSignals, PlanDelta primitives (C structs) with tiny stubs - Lightweight ADMM-lite coordination in admm_lite.c - Toy demo and test harness under delta_mesh/ (demo_main.c, test.sh) - An AGENTS.md documenting project governance and integration approach How to run the MVP demo - Ensure you have a C toolchain (gcc) available. - From the repo root, run: ./test.sh This will compile a small demo that fabricates two venue inventories and shows an aggregated quote produced by a toy ADMM-like step. Problem: Cross-venue options liquidity is fragmented and current market-making tools force users to share sensitive inventory, quotes, and risk signals with centralized servers, exposing edge data and increasing regulatory/compliance risk.
