P2P Prayer Market

Why Call It a “Market”?

User Lifecycle & Interaction Flow

1. On‑boarding – Create an account, give consent, optionally set language, time‑zone, and prayer style.
2. Placing a “Sell Order” – Write a prayer request, tag it, set priority, and submit. This marks you as having a pending sell order (you now owe a prayer).
3. Receiving a “Buy Order” – The matching engine routes a new request to you, you get a notification with the prayer text and optional note.
4. Closing the Transaction – After you’re notified, your sell order is marked fulfilled; you can place a new request.

Matching Engine – The “Market Maker”

Core algorithm (FIFO + Preference Scoring)

• Queue all pending givers.
• When a new request arrives, compute a compatibility score:
  • Same language (+30)
  • Overlapping tags (+20 per tag)
  • Time‑zone proximity (+10)
  • Reciprocity credit (+5)
  • Random tie‑breaker (0)
• Select the highest‑scoring giver; fall back to FIFO if needed.

Advanced market‑style features (optional)

• Karma tokens for priority boosts.
• Virtual “price” for high‑priority requests.
• Batch orders for families or groups.

Privacy, Security & Ethical Safeguards

Community Governance & Moderation

• Automated profanity/hate‑speech filters on submission.
• “Report” button on every received prayer → moderation queue.
• Volunteer moderator panel (elected by community) for review and sanctions.
• Reputation system:
  • Completion Ratio badge (★‑style).
  • Thank‑You Score (average 1‑5).
• Clear community guidelines emphasizing respect, inclusivity, and non‑coercion.

Component choices

• Front‑end: React (Web) + React Native or Flutter (Mobile).
• API: FastAPI (Python) or NestJS (Node).
• Auth: Keycloak or Auth0 (OAuth2/JWT, optional MFA).
• DB: PostgreSQL with pgcrypto for encrypted columns.
• Cache/Queue: Redis Streams (low‑latency) + RabbitMQ fallback.
• Search/Filter: Elasticsearch or Postgres GIN on JSONB tags.
• Notifications: Firebase Cloud Messaging (Android/Web) & APNs (iOS).
• Observability: Prometheus + Grafana, Loki for logs, Sentry for errors.
• Infra: Docker + Kubernetes (managed service).
• Secrets: HashiCorp Vault or cloud‑native secret manager.
• CI/CD: GitHub Actions → Docker → Helm chart deploy.

Monetisation & Sustainability

Growth & Outreach Strategy

• Launch‑beta community with faith‑based groups; early‑adopter badges.
• Referral program – earn gratitude tokens for successful invites.
• Content marketing – blog posts on reciprocity, stories of answered prayers.
• Social media – short animated reels showing a prayer exchange in 30 seconds.
• Partnerships – embed in devotional apps via deep links.
• Localized launches – translate UI & tags into major languages.
• Metrics‑driven iteration – track fulfillment time, churn, thank‑you scores; A/B test UI copy.
