Bifrost System

The Rainbow Bridge — Cross-System Communication

Overview

Bifrost is the integration layer that connects all Liana Banyan systems. Named after the rainbow bridge in Norse mythology that connects realms, Bifrost enables seamless communication between the platform’s various components while maintaining security and audit trails.

Key Features

1. Event-Driven Communication

All system interactions are published as events, enabling loose coupling between components.

2. Audit Trail

Every cross-system interaction is logged in the IP Ledger for transparency and debugging.

3. Rate Limiting

Bifrost implements intelligent rate limiting to prevent system overload during high-traffic periods.

4. Retry Logic

Failed communications are automatically retried with exponential backoff.

Event Types

Implementation

// Bifrost event publishing
await bifrost.publish({
  event: 'credit.granted',
  source: 'gleaning-system',
  payload: {
    userId: user.id,
    amount: 100,
    reason: 'daily_grant'
  },
  timestamp: new Date()
});

// Bifrost subscription
bifrost.subscribe('credit.granted', async (event) => {
  await checkMilestoneUnlock(event.payload.userId);
  await updateMedallionProgress(event.payload);
});
