Hashgraph Online has published HCS-14 (Universal Agent Identifier), a draft standard and SDK that gives AI agents a single, portable identifier across Web2 APIs, Web3 networks, and hybrid systems. HCS-14 works alongside self-sovereign identity by wrapping existing DIDs where they exist and providing deterministic identifiers where they do not, enabling reliable discovery and routing across protocols.

Status: Draft. We welcome feedback from the community at https://github.com/hashgraph-online/hcs-improvement-proposals/discussions/135.

HCS‑14 is network‑agnostic. It works across Web2 (A2A/REST), EVM/ETH, and more. Hedera support is optional. We start with Web2 and EVM, then cover Hedera.

TL;DR​

• A single, portable identifier (UAID) for agents across Web2 and Web3
• Two modes: deterministic AID or wrap your existing DID
• Minimal routing hints for discovery; identity details stay in DID docs/profiles

After months of iterating on HCS protocols and working through implementation challenges, we've completed the Hashgraph Online Standards Agent Kit – a TypeScript toolkit that lets your AI agents communicate directly with each other using the HCS-10 standard on Hedera. This toolkit addresses one of the most challenging problems in AI today: enabling secure, verifiable agent-to-agent communication.

"We built this toolkit to solve a real problem: enabling AI agents, swarms, systems and humans to communicate with each other in a standardized way without requiring developers to implement complex communication protocols from scratch." - Michael Kantor, President, Hashgraph Online DAO

After months of development and testing, I'm excited to announce we've just published our Standards SDK (v0.0.44) to npm. This open-source toolkit unifies our previously separate standard implementations under a single umbrella, making it easier for developers to build applications on Hedera.

"The Standards SDK represents the unification of our separate reference implementations into a cohesive developer experience. It's designed to grow with the ecosystem." - Michael Kantor

We're thrilled to announce that the Hashgraph Online DAO LLC is now officially established! This marks a pivotal step towards building a fully on-chain internet utilizing Hedera's Consensus Service (HCS) to interconnect data on various blockchains.

"The establishment of Hashgraph Online is more than just an organizational milestone; it represents the first step in building a new digital infrastructure, fully on-chain, open, and accessible to all." - Michael Kantor, President, Hashgraph Online
