+title: "Ceremony"
+---
+
+Union's Ceremony has the following components:
+
+- Web app [ceremony.union.build](https://ceremony.union.build)
+- [MPC client](https://github.com/unionlabs/union/pkgs/container/union%2Fmpc-client), running in the terminal 
+- The coordinator, managing the queue and aggregating uploads.
+
+We use [Nix](https://nixos.org) to create fully reproducible builds of all components and provide commands so that you can build them yourself.
+
+## Web App
+
+Deployed on [ceremony.union.build](https://ceremony.union.build), Handles auth and shows queue status. Also shows all contributions.
+
+You can build it locally like this:
+
+```sh
+GIT_LFS_SKIP_SMUDGE=true nix build github:unionlabs/union/release/ceremony#ceremony
+```
+
+## MPC Client
+
+Image published [here](https://github.com/unionlabs/union/pkgs/container/union%2Fmpc-client), handles the generation of the contribution, generation of the gpg key, and signs/uploads the contributions.
+
+You can build it locally like this on a `x86_64-linux` machine:
+
+```sh
+GIT_LFS_SKIP_SMUDGE=true nix build github:unionlabs/union/bbfaa2f39d0183c2fd6c1d2505fad6c64ddb39e1#packages.x86_64-linux.mpc-client -L
+```
+
+and load the image like this on a `x86_64-linux` machine::
+
+```sh
+docker load -i ./result
+```
+
+## MPC Coordinator
+
+The coordinator has two components:
+
+1. Postgres, managing the queue and contributions. Hosted by Supabase.
+3. The `mpc-coordinator` service, verifying incoming contributions. Hosted by Hetzner.
+
+
+You can see the database schema [here](https://github.com/unionlabs/union/blob/bbfaa2f39d0183c2fd6c1d2505fad6c64ddb39e1/mpc/coordinator/database.sql), and you can build the service locally like this on a `x86_64-linux` machine:
+
+```sh
+GIT_LFS_SKIP_SMUDGE=true nix build github:unionlabs/union/bbfaa2f39d0183c2fd6c1d2505fad6c64ddb39e1#packages.x86_64-linux.mpc-coordinator -L
+```
+There are no trust assumptions on the database, as at the end of the ceremony all contributions will be published and verifiable by all.
