Hardware wallet for PLC rotation key

Atproto, the protocol behind Bluesky, allows for the decentralization of many components of the platform. Today, I want to discuss how it manages identity with public key distribution and key rotation and introduce a new application I am developing.

Currently, a Bluesky identity is attached to a global identifier (did:plc) stored on one centralized server, the PLC directory. This identifier resolves to a set of public keys, which we will discuss later, and a pointer to the Personal Data Server (PDS) where the user content is stored.

Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider ATProto network. - https://atproto.com/guides/self-hosting

Set up your personal ATProto PDS with NixOs

This guide walks you through the process to host your own PDS instance using NixOs, agenix for secure environment management, and Caddy as a reverse proxy for traffic encryption.

Thanks to the Nixpkgs contributors for making this possible!

You need to have a server running NixOs. Using nixos-anywhere makes it easy to install on a vps. The server configuration should be in a NixOs flake.
