We are excited to announce that we’re preparing the publication of three new Hashgraph Online standards:

• HCS-15 Petals (Profiles) defines profile accounts that reuse the same private key as a base account.
• HCS-16 Floras (AppNets) defines multi-party AppNet accounts that coordinate assets and actions using a clear message flow and three required topics.
• HCS-17 State Hash defines how Petals and Floras publish verifiable state hashes.

All three documents are Status: Draft, Version 1.0.

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
