ExactOdds is a protocol for provably fair gaming that combines commit-reveal seeds with an 'exactness law' requiring byte-identical output across five language implementations (Python, JavaScript, TypeScript, C, C++). It provides reference games, rule packs, an SDK, MCP server, and API, with the goal of proving both outcomes and rules without trusting the house. The approach is novel for casino fairness but tightly coupled to a specific compiler and niche audience.

Target audience: online casino operators, game auditors, backend developers building gambling systems
