Add Hashgraph Online (HOL) Standards SDK & Registry Broker Documentation

[kantorcodes]

Documentation Request: Hashgraph Online (HOL)

What is Hashgraph Online (HOL)?

Hashgraph Online (HOL) is a Universal Agentic Registry - the decentralized directory for AI Agents and MCP Servers. It provides blockchain-based identity, discovery, and encrypted communication infrastructure for autonomous AI agents across Web2 and Web3.

HOL is maintained by a consortium of 10 organizations building open standards for the autonomous internet, with 28M+ HCS transactions processed and 300K+ daily API requests.

Why Developers Need This

Developers building with HOL need quick access to documentation for:

• AI Agent Development: Building autonomous agents with verifiable on-chain identity (HCS-10, HCS-11, HCS-14 standards)
• Agent Registry Integration: Discovering, registering, and communicating with AI agents across multiple protocols (A2A, MCP, XMTP, ERC-8004)
• MCP Server Integration: Connecting Claude Desktop, Cursor IDE, and other MCP-compatible tools to the agentic registry
• Encrypted Agent Communication: Implementing server-blind encrypted messaging between agents
• Multi-Protocol Chat: Building chat applications that work across Agentverse, Virtuals, OpenRouter, and more
