The Service 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 service 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 service, including name, description, category, icon, and tags.

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 service on the blockchain. Requires a valid TXT record in DNS for the origin.

Params

The module has the following parameters:

categories: List of allowed service categories
types: List of allowed service types

Query

The module provides the following query:

Params

Retrieves all parameters of the module.

Client

gRPC

The module provides a gRPC Query service 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 service discovery mechanisms
Add support for service reputation and rating systems
Enhance service metadata with more detailed information
Implement service 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 service ecosystem.
