Three changes target the scan pipeline's two bottlenecks (HTTP latency and main-thread ECDH): - Cache per-block tweak + UTXO data in IndexedDB (blockCache.ts) and route fetches through it. Mined blocks below the indexer tip are immutable, so a repeat or overlapping scan now costs zero round-trips for blocks already seen. Keyed by (indexerUrl, height); degrades gracefully when IndexedDB is unavailable. - Move the secp256k1 ECDH + per-output Pk derivation into a dedicated Web Worker (scan.worker.ts + scanWorkerClient.ts). The scan loop no longer has to setTimeout(0) every 64 entries to keep the UI responsive, and fetching now overlaps with ECDH. The client falls back to a main-thread scan if the worker can't be constructed or errors on a block. bscan stays on-device — a same-origin Worker is not the remote scan-helper pattern BIP-352 contemplates. - Make fetch concurrency tunable via AppConfig.bip352ScanConcurrency (clamped to [1, 32], default 8) so a fast self-hosted indexer can run hotter than the polite public-host default.
Agora
Power to the people.
Agora is a Nostr client focused on community ownership, expressive identity, and censorship resistance. This repository (agora-3) is the Agora-branded app built from the Ditto codebase.
What This Repo Is
- Agora product identity (name, theme, assets, native IDs)
- Ditto-derived implementation with broad Nostr feature coverage
- Configurable deployment defaults via
agora.json
Features
- Community-first social client: notes, articles, comments, reposts, reactions, and rich event rendering
- Theming system: built-in presets + custom color/font/background themes that can be shared as events
- Lightning support: zaps with Nostr Wallet Connect and WebLN
- Private messaging: NIP-04 and NIP-17 direct messages
- Mobile app shell: Capacitor-powered Android/iOS wrappers
- Self-hostable: static web build + configurable relay and upload infrastructure
Getting Started
Prerequisites
- Node.js 22+
- npm 10.9.4+
Development
git clone https://gitlab.com/soapbox-pub/agora-3.git
cd agora-3
npm install
npm run dev
Development server: http://localhost:8080
Docker Getting Started
Use Docker Compose when you want the nginx reverse-proxy stack (necessary if you want decryptable media in messages - kind 15s of NIP 17):
git clone https://gitlab.com/soapbox-pub/agora-3.git
cd agora-3
cp .env.example .env
docker compose up --build
Proxy URL: http://localhost:8083
This starts:
viteservice on the internal Docker network (vite:8080)webservice (nginx) on host port8082, proxying to Vite with websocket support
Stop stack:
docker compose down
Production-style container build:
docker compose -f docker-compose.prod.yml up --build
Build
npm run build
Build output: dist/
Validate
npm test
This runs type-checking, linting, unit tests, and production build checks.
Configuration
Build-time config is read from agora.json (gitignored by default so each deployment can provide its own values).
{
"theme": "dark",
"relayMetadata": {
"relays": [
{ "url": "wss://relay.ditto.pub", "read": true, "write": true },
{ "url": "wss://relay.primal.net", "read": true, "write": true },
{ "url": "wss://relay.damus.io", "read": true, "write": true }
]
},
"blossomServers": [
"https://blossom.ditto.pub",
"https://blossom.primal.net/"
]
}
Configuration priority (highest first):
- User settings (local storage)
- Build config (
agora.json) - Hardcoded app defaults
Use a custom config path:
CONFIG_FILE=./my-config.json npm run build
Deployment
Agora builds to static files and can be deployed to any static host.
- GitLab/GitHub Pages
- Netlify/Vercel
- VPS or any web server with SPA routing fallback
For Android:
npm run build
npx cap sync
npx cap open android
