The svc module is responsible for managing the registration and authorization of services within the Sonr ecosystem. It provides a secure and verifiable mechanism for registering and authorizing services using Decentralized Identifiers (DIDs).

Concepts

Service: A decentralized svc on the Sonr Blockchain with properties such as ID, authority, origin, name, description, category, tags, and expiry height.
Profile: Represents a DID alias with properties like ID, subject, origin, and controller.
Metadata: Contains information about a svc, including name, description, category, icon, and tags.

Dependencies

State

The module uses the following state structures:

Metadata

Stores information about services:

Primary key: id (auto-increment)
Unique index: origin
Fields: id, origin, name, description, category, icon (URI), tags

Profile

Stores DID alias information:

Primary key: id
Unique index: subject,origin
Fields: id, subject, origin, controller

Messages

MsgUpdateParams

Updates the module parameters. Can only be executed by the governance account.

MsgRegisterService

Registers a new svc on the blockchain. Requires a valid TXT record in DNS for the origin.

Params

The module has the following parameters:

categories: List of allowed svc categories
types: List of allowed svc types

Query

The module provides the following query:

Params

Retrieves all parameters of the module.

Client

gRPC

The module provides a gRPC Query svc with the following RPC:

Params: Get all parameters of the module

CLI

(TODO: Add CLI commands for interacting with the module)

Events

(TODO: List and describe event tags used by the module)

Future Improvements

Implement svc discovery mechanisms
Add support for svc reputation and rating systems
Enhance svc metadata with more detailed information
Implement svc update and deactivation functionality

Tests

(TODO: Add acceptance tests for the module)

Appendix

This module is part of the Sonr blockchain project and interacts with other modules such as DID and NFT modules to provide a comprehensive decentralized svc ecosystem.
