What is Daemon? ​

The Daemon is a critical infrastructure component that acts as an adapter between AI services and clients on the SingularityNET platform.

Daemon Architecture

Core Functionality ​

Primary Responsibilities ​

The Daemon performs several essential functions:

  • Request Routing - Receives client requests and forwards them to the appropriate AI service
  • Payment Tracking - Monitors service calls and calculates costs in real-time
  • Protocol Adaptation - Supports multiple service protocols (gRPC, HTTP/JSON-RPC)
  • Free Call Management - Tracks and validates free trial calls
  • Security Gateway - Acts as the public-facing entry point for all service requests

Architecture Overview ​

Key Components ​

  1. Public Endpoint

    • Must be accessible from the internet
    • Handles incoming client connections
    • SSL/TLS support for secure communication

  2. Payment Processor

    • Validates payment channels
    • Verifies sufficient funds
    • Updates channel state off-chain

  3. Service Connector

    • Connects to backend AI services
    • Supports multiple protocols
    • Handles service discovery

  4. State Management

    • ETCD integration for distributed state
    • Channel state synchronization
    • Transaction logging

Deployment Requirements ​

Infrastructure Needs ​

  • Public IP Address or domain name
  • Open ports for client connections
  • SSL certificates for HTTPS endpoints
  • ETCD instance for state storage

Configuration Options ​

The Daemon supports flexible deployment scenarios:

  • Standalone - Single daemon instance
  • Clustered - Multiple daemons with shared ETCD
  • Load Balanced - Behind reverse proxy or load balancer
  • Containerized - Docker/Kubernetes deployment

Getting Started ​

Installation Steps ​

  1. Download the latest daemon binary from GitHub Releases
  2. Configure using the provided templates
  3. Deploy with your AI service
  4. Test using CLI or SDK

Security Considerations ​

Best Practices ​

  • Always use SSL/TLS for production deployments
  • Secure ETCD endpoints with authentication
  • Regular security updates and patches
  • Monitor daemon logs for suspicious activity
  • Implement rate limiting for public endpoints
