COG-2: Decentralised ID

Status:      Draft 
Version:     1.0 
Created:     2025-09-23 
Authors:     Mike Anderson

This standard specifies the methods for identifying venues and other resources on the grid

Purpose​

The Grid enables secure and efficient collaboration between AI agents, data providers, and compute resources across organisational boundaries.

In order to operate effectively as a protocol, it is necessary to be able to identify venues and resources with stable global IDs.

Specification​

Venue DID​

A venue MUST provide a W3C compatible did, e.g. did:web:venue-1.covia.ai

The DID must utilise one of the following methods:

  • did:web for venues identified by a public URL with HTTPS
  • did:key for other venues
  • did:convex for venues registered on the Convex network

A venue MAY provide multiple equivalent DIDs which resolve to the same venue. If it does so, it MUST provide a canonicalID which specifies its primary DID, and return this as the id property for its DID document.

Asset DID​

Assets MUST have a DID constructed where:

  • The path is /a/{asset-id}
  • {asset-id} is the Asset ID, i.e. the SHA256 hash of the asset metadata, in hexadecimal

Example:

did:web:venue-1.covia.ai/a/14a3a6b804629835f5466d03f789dd92a45381474d58c1224dfe344e6934c022

The hexadecimal asset ID MAY be prepended by 0x and/or contain a mix of uppercase and lowercase characters.

The canonical ID of an asset MUST exclude 0x and be in lowercase.

Venues SHOULD be capable of providing a DID document for any asset they host, subject to authorisation.
