Brainstorming a Nostr indexing node.

Why

Modern applications may want:

• More advanced querying than currently supported by Nostr relays
• Receiving messages in a batch via API, not one at a time over a websocket
• Fewer expensive cryptographic operations done client-side (e.g. trusting an indexer to validate events)
• To retrieve large amounts of messages quickly+reliably via one API without caring about uptime/featuresets of multiple relays

Solution

• A server that pulls events from all known relays, storing them forever-ish and making available to clients via API

Risks

• Centralization - Need to avoid Infura-ization

MVP Design

Stack

• NodeJS
• TypeScript
• Postgres?
• REST API (to start?)
• GraphQL (eventually?)
