Hashgraph Online (HOL), legally structured as Hashgraph Online DAO LLC, is a decentralized standards organization dedicated to architecting a fully on-chain "Agentic Internet." Their strategic objective is to serve as the primary trust engine for the decentralized web, deploying sophisticated open-source protocols and infrastructure that enable AI agents to communicate securely, maintain verifiable reputations, and operate autonomously via the Hedera Hashgraph network.
Officially launched on November 7, 2024, and headquartered in the Marshall Islands, Hashgraph Online is led by President Michael Kantor. The organization operates as a decentralized consortium supported by ten pioneering Web3 organizations—including HashPack, Bonzo Finance, Builder Labs, and SentX—which collectively govern the adoption and evolution of its standards.
