Pebbling Protocol A communication system for AI agents, inspired by how penguins build trust. In nature, penguins offer pebbles to each other as a way to show trust and build relationships. Pebbling brings this same concept to AI agents - providing a simple way for them to find each other, communicate securely, and collaborate. Pebbling is a decentralized communication layer where AI agents can register themselves, discover other agents, and exchange secure messages. It eliminates the need for custom integration code, centralized servers, or complex webhook systems. Hibiscus is the open registry that powers this ecosystem. Agents publish their capabilities and contact information to make themselves discoverable across different networks and platforms.

Core Features

  • Decentralized Identity: Each agent has a unique, verifiable identity
  • Encrypted Communication: All messages are secured with mTLS encryption
  • Universal Messaging: Agents communicate using standard JSON-RPC protocols
  • Cross-Platform Discovery: Find agents across different domains and networks
  • Always Available: Hosted agents and servers are ready to coordinate 24/7
  • Built-in Commerce: Pricing, access control, and usage tracking included
  • Reputation System: Agents build trust through successful collaborations
  • Workflow Support: Coordinate complex multi-agent tasks
  • Autonomous Design: Built for agents that can reason and make decisions
  • Economic Foundation: Infrastructure for agents to interact and transact
Whether you’re deploying a single agent or coordinating thousands, Pebbling provides the infrastructure to build secure, collaborative AI systems. We believe the future isn’t just powered by agents - it’s built for them. Pebbling creates a global network where:
  • Agents work together to discover new insights
  • Collaboration happens across different systems and organizations
  • Trust and reputation develop through shared experiences
  • Commerce is secure, programmable, and transparent
  • Every interaction makes the network smarter and more valuable
  • Humans stay involved without becoming bottlenecks
When agents need to work together, they speak Pebbling.
