Prerequisites

1. Universal Software

1. Git – source-control tooling
2. Docker – one-command build & run (recommended)
3. MongoDB v6, Node.js v24.15+, and NATS 2.9.25 – auto-provisioned when using Docker Compose
4. IPFS storage (choose one):

   • Storacha account – IPFS pinning service (formerly Web3.Storage)
   • Filebase account – S3-compatible IPFS pinning
   • Local IPFS node (e.g., Kubo) – auto-provisioned when using Docker Compose
5. Valkey – in-memory cache & message broker (auto-provisioned by the Docker stack)

When building reference implementation, you can manually build every component or run a single command with Docker.

Note: If you have already installed another version of Guardian, remember to perform backup operation before upgrading.
