Practical examples showcasing the Depinkit stack for building decentralized applications.

Depinkit is a collection of packages for building secure, decentralized systems:

• Actor - Secure actor programming framework
• Network - P2P networking with libp2p
• UCAN - User Controlled Authorization Networks
• DID - Decentralized Identifiers
• Crypto - Cryptographic operations

These packages power NuNet's Device Management Service, a decentralized compute network.

A UCAN-protected messaging application demonstrating:

• Hierarchical permissions (Admin grants read/write to users)
• Fine-grained access control (separate read and write permissions)
• P2P direct messaging with reciprocal invitations
• UCAN delegation without pre-configured trust
• Pub/sub channels with capability validation
• Clean architecture with proper separation of concerns

Difficulty: Beginner
Concepts: UCAN delegation, actor behaviors, pub/sub, direct messaging

1. Start with: messaging - Clean introduction to UCAN delegation and actor communication
2. Deep dive: Check individual package documentation
3. Build: Create your own decentralized application!

The Depinkit stack enables:

• Messaging Systems: Secure chat with hierarchical permissions (see messaging example)
• Decentralized Compute: Distribute tasks across P2P network
• Storage Networks: Decentralized file storage with access control
• IoT Networks: Sensor data sharing with fine-grained permissions
• CDN/Edge Computing: Distributed content delivery
• Collaborative Systems: Multi-party workflows with zero trust
• Social Networks: Community platforms with delegated moderation
• Resource Marketplaces: Any DePIN use case requiring authorization

• Zero trust architecture
• Capability-based access control
• Cryptographic verification
• No central authority

• P2P discovery via DHT
• NAT traversal (relay/hole-punching)
• Direct messaging
• Topic-based pub/sub

• Message-driven architecture
• Behavior-based dispatch
• Request-response patterns
• Broadcast messaging

• Self-contained authorization
• Delegation chains
• Hierarchical permissions
• Time-limited access
• Revocation support
