Definitions

A formal set of definitions used within the Hashgraph Consensus Standards Improvement proposals. These are NOT standards and should be used for reference only.

Spheres

Spheres are the HCS equivalent of DNS. Every Sphere is a Topic ID which includes the current records.
Messages written to a Sphere are NOT valid unless the payer_account_id owns the matching .ℏ domain from https://kabuto.sh

Resource (Conceptual Addresses)

A resource is any piece of data on Hedera that is referenced by an entity id on Hedera / Hashgraphs. Valid entities are Topic IDs.

Hashgraph Resource Locator

The protocol for finding data inscribed on the Hedera Consensus Service, following the Hashgraph Consensus Standards.

an HRL locates a resource. The format for an HRL is as follows. A formal future HCS will cover all cases for HRLs.
hcs://{protocol_standard}/{resource_id}
protocol_number should always be a valid HCS standard, eg 1
resource_id should always be a valid Resource
A valid example of an HRL is: hcs://1/0.0.123456

Public Registries

Topic Ids which are managed by the community for the convenience of the ecosystem. These topics are public and not managed by a specific entity. Proceed with caution when consuming data inscribed on these topics.

Guarded Registries

Topic Ids which are managed by the HCS Council for the convenience of the ecosystem. These topics should be private topics to ensure proper validation of messages. HCS will cover this idea in detail.

Hashsite

A fully rendered decentralized application, composed of valid HTML Markup, JavaScript, and CSS which is inscribed following HCS standards.

Hashgraph Package Management (HPM)

A registry of pointers to various scripts that clients can download to create Hashsites.
The registry will be browsable on hpm.h
HPMs can be installed through inscriptions reference to develop Hashsites eg <script src=”hpm.h/date-fns” />
