Use Cases

Macula enables a wide range of decentralized applications across multiple domains. Here are some real-world scenarios where Macula provides the ideal infrastructure.

Business Applications

Partner Networks

Organizations need to share services and capabilities without centralizing control or data.

Example: Supply chain collaboration where multiple companies track shipments, share inventory status, and coordinate logistics without a single company controlling the platform.

Why Macula:

  • Each organization runs nodes on their own infrastructure
  • Services are discovered via DHT without centralized registry
  • Data stays within organizational boundaries
  • Multi-tenancy via realms ensures isolation between partners

Supply Chain Tracking

Track goods and events across multiple companies' infrastructure without a central database.

Example: Farm-to-table food tracking where farms, processors, distributors, and retailers each publish events about product movements, with consumers able to trace the complete journey.

Why Macula:

  • Events published via pub/sub stay with the originating organization
  • Downstream parties subscribe to relevant event streams
  • No single point of failure or data custody
  • Real-time updates without API polling

Collaborative Platforms

Teams work together without depending on a single SaaS vendor.

Example: Research collaboration platform where universities and research institutions share datasets, computational resources, and results without centralizing sensitive research data.

Why Macula:

  • Institutions maintain sovereignty over their data
  • RPC enables distributed computation requests
  • Pub/sub enables real-time research updates
  • Works across institutional firewalls via HTTP/3

IoT & Edge Computing

Smart Homes

Devices communicate locally without cloud dependency.

Example: Home automation where lights, thermostats, sensors, and controllers coordinate via the local mesh, continuing to operate even during internet outages.

Why Macula:

  • Devices discover each other via mDNS locally
  • Pub/sub for event broadcasting (motion detected, temperature changed)
  • RPC for device control (turn on lights, adjust temperature)
  • No cloud latency or bandwidth costs
  • Privacy: data stays within the home

Industrial Automation

Factories continue operating during network outages.

Example: Manufacturing floor where robots, sensors, quality control systems, and inventory management coordinate production without relying on centralized cloud services.

Why Macula:

  • Local mesh operates independently of WAN connectivity
  • Real-time control via RPC (< 10ms latency)
  • Event streams for monitoring and analytics
  • Fault tolerance via OTP supervision
  • Scales to thousands of sensors and actuators

Distributed Sensor Networks

Environmental monitoring, agriculture, infrastructure health.

Example: Agricultural IoT network where soil moisture sensors, weather stations, irrigation controllers, and drones share data and coordinate actions across a large farm.

Why Macula:

  • Sensors publish readings via pub/sub
  • Controllers subscribe to relevant sensor streams
  • RPC for remote commands (start irrigation, launch drone survey)
  • Works through rural NAT/firewall constraints
  • Edge processing reduces bandwidth usage

Adaptive & Collaborative AI

TWEANN-Based Systems

Neural networks that evolve topology and weights locally, then share insights.

Example: Adaptive manufacturing optimization where each production line runs TWEANN agents that learn optimal parameters, then share successful mutations across the mesh.

Why Macula:

  • Each edge node runs local evolutionary algorithms
  • Successful genome variations published via pub/sub
  • Other nodes subscribe and integrate improvements
  • No centralized training infrastructure needed
  • Continuous adaptation to local conditions

Federated Learning

Train models across distributed nodes without centralizing data.

Example: Healthcare diagnostics where hospitals train ML models on local patient data, share model updates (not data) via the mesh, and collaboratively improve diagnostic accuracy.

Why Macula:

  • Model updates published as events (not raw data)
  • Privacy-preserving: data never leaves institutions
  • Gradual convergence via distributed gradient sharing
  • Works across institutional network boundaries
  • Multi-tenancy ensures proper isolation

Edge Intelligence

Decision-making at the edge with selective cloud synchronization.

Example: Autonomous vehicle fleet coordination where vehicles make local decisions using onboard AI, share observations and planned maneuvers via the mesh, and only sync aggregated data to the cloud.

Why Macula:

  • Low-latency local decision making (< 5ms)
  • Real-time coordination via pub/sub
  • RPC for requesting assistance from nearby vehicles
  • Operates during cellular network dropouts
  • Selective cloud sync reduces bandwidth costs

Gaming & Real-Time Applications

Multiplayer Game Meshes

Players connect peer-to-peer without dedicated servers.

Example: LAN party games where players discover each other locally, form game sessions, and play without internet connectivity or centralized game servers.

Why Macula:

  • mDNS for local player discovery
  • Pub/sub for game state synchronization
  • RPC for player actions
  • Works offline, no server hosting costs
  • Realm isolation per game session

Collaborative Editing

Real-time document collaboration without centralized services.

Example: Privacy-focused collaborative editor where teams edit documents in real-time, with all data staying within the organization's infrastructure.

Why Macula:

  • Operational transforms via pub/sub
  • Cursor positions and selections as events
  • RPC for conflict resolution
  • Works through corporate firewalls
  • No data leaves organizational control

Infrastructure & Networking

Content Delivery Networks

Decentralized content distribution at the edge.

Example: Community CDN where participants cache and serve content to local peers, reducing bandwidth costs and improving latency without centralized CDN providers.

Why Macula:

  • DHT-based content discovery
  • Pub/sub for cache invalidation
  • RPC for content requests
  • Scales organically as nodes join
  • No CDN provider fees

Service Mesh for Edge Computing

Microservices at the edge with automatic discovery.

Example: Edge computing platform where microservices discover dependencies, route requests, and balance load across edge nodes without centralized orchestration.

Why Macula:

  • Service registry via DHT
  • Pub/sub for service health events
  • RPC with automatic failover
  • Multi-tenancy for SaaS deployments
  • Works through NAT and firewalls
