In MPC a set of n parties are running a distributed computation over private inputs. To do so, MPC protocols designers make assumptions on the required network and communication channels. A complete p2p network setup might turn out to be costly, effectively eliminating the practicallity of running MPC at scale. \n\nInstead, we suggest using untrusted coordinator, connected in a star topology to all clients. This gets us immidiate improvment on communication complexity of simple p2p, and potentially benefits robustness, accountabillity and fault tolarance. \n\n\n### Project Status: \nThe current stage is focused on the idea of replicated state machine. The repo contains three proofs of concepts. \nThe latest implementation uses Tendermint to replicate the state machine across a set of known servers.\nClients broadcast transactions to the servers to change the state, and read messages from the public bulletin board. Older PoCs are using a single untrusted coordinator. \n\n- **[Tendermint](https://github.com/KZen-networks/white-city/tree/master/RelayProofsOfConcept/EddsaTendermintServer):** Broadcast channel using Tendermint as an immutable bulletin board.\n- **[TokioServer](https://github.com/KZen-networks/white-city/tree/master/RelayProofsOfConcept/EddsaTokioServer):** a socket level implementation using Tokio Crate.\n- **[RocketServer](https://github.com/KZen-networks/white-city/tree/master/RelayProofsOfConcept/EddsaRocketServer):** a Http server implementation using Rocket crate. \nProofs of concept are currently running [multi party EdDSA](https://github.com/KZen-networks/multi-party-eddsa) library. In general, all messages in the MPC protocol should be broadcast messages (p2p messages are broadcasted encrypted). \n\nAs a side project there is also an effort to formally verify the centralized state machine model in [Coq/TLA+](https://github.com/KZen-networks/white-city/tree/master/RelayProofsOfConcept/Formal-spec)\n\n### Hall of Fame: \nHere is a list of contributors to White City (not ordered): \n- Avi Kozokin\n- Alex Manuskin\n- Frederic Peschanski\n- Omer Shlomovits \n- Roman Zeyde\n- Haoyu LIN\n\n\n### Want to Contribute:\nPlease send an email to github@kzencorp.com containing your github username.
