📄️ HCS-1 Standard: File Data Management with Hedera Consensus Service
The HCS-1 standard provides a systematic approach to encode, chunk, upload, retrieve, and reassemble file data for applications using Hedera Consensus Service (HCS). This process is agnostic of the implementation details, focusing on the JSON structure and the use of a Topic ID for efficient data management.
📄️ HCS-2 Standard: Advanced Topic Registries
The HCS-2 standard defines advanced topic registries for Hedera Consensus Service, enabling structured data organization and retrieval.
📄️ HCS-3 Standard: Recursion within Hedera Consensus Service
The HCS-3 standard defines a method for implementing recursion within Hedera Consensus Service, enabling more complex data structures and relationships.
📄️ HCS-5 Standard: Tokenized HCS-1 Files, **Hashinals**
This specification provides a standard way to "inscribe" Hashinals utilizing the Hedera Consensus and Hedera Token Services. Hashinals borrow many ideas from Ordinal theory on Bitcoin, and apply them in a more efficient, and scalable way for the Hedera Hashgraph.
📄️ HCS-6 Standard: Dynamic Hashinals
The HCS-6 standard defines a framework for creating dynamic Hashinals on the Hedera Hashgraph, enabling interactive and updatable on-chain assets.
📄️ HCS-7: Smart Hashinals - A Micro-DSL for Deterministic Topic Selection
HCS-7 enables dynamic NFTs (Hashinals) whose metadata automatically updates based on smart contract state using a micro-DSL for deterministic topic selection and WASM processing. This standard supports creating reactive, state-dependent NFTs without requiring additional transactions for updates.
📄️ HCS-8 Standard: Poll Topic Standard
The HCS-8 standard introduces a framework to use Hedera Consensus Service (HCS) topics to manage polls.
📄️ HCS-10 ConvAI Standard: AI Agent Communication on HCS
The HCS-10 standard establishes a framework for AI agents to autonomously communicate using the Hedera Consensus Service (HCS). This includes creating accounts, registering agents in a registry, and securely managing AI-to-AI and human-to-AI communication channels. HCS-10 provides scalable, secure, and decentralized communication solutions while leveraging existing Hedera standards.
📄️ HCS-11 Standard: Profile Standard
The HCS-11 standard defines a systematic approach for managing profiles on the Hedera Hashgraph through account memos, enabling rich identity management for individuals and AI agents.
📄️ HCS-13 Standard: Schema Registry and Validation
This specification provides a standard way to define, register, and reference schemas for data validation and structure in the Hedera ecosystem, enabling type-safe data exchange and improved interoperability.
