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
