HCS-14: Universal Agent IDs for Web2 and Web3

· 9 min read
Michael Kantor
President, Hashgraph Online DAO

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

HCS-19: A New Privacy Standard for AI Agents

TL;DR

Hashgraph Online has published a draft standard called HCS-19: AI Agent Privacy Compliance, designed to help AI agents prove they handle user data responsibly. The standard defines how to log consent, privacy notices, data processing, rights requests, and audits on Hedera Consensus Service (HCS), making compliance transparent, verifiable, and interoperable.

Leading the effort is PrivacyCheq's aiCheq, an API that allows AI agents to collect, manage, and prove consent in real time, supported by Hedera-based auditing. Together, HCS-19 and aiCheq establish the foundation for trustworthy, privacy-aware AI.
