AXES Connect

1. Introduction

AXES Connect is a comprehensive library designed to facilitate the management of Decentralized Identifiers (DIDs), associated credentials, and Token Bound Accounts (TBAs) within the AXES ecosystem. This technical documentation provides an in-depth overview of the system's architecture, components, and functionalities.

1.1 Objectives

• Provide a robust and flexible library for managing DIDs and associated credentials

• Ensure compliance with W3C DID specifications

• Support multiple types of credential and token issuance

• Offer methods for verifying credentials, signatures, and JSON Web Tokens (JWZ)

• Enable seamless creation and management of Token Bound Accounts (TBAs)

1.2 Assumptions

• The library will be used by systems requiring DID management and credential verification

• Integration with blockchain networks or decentralized storage systems for DID registration and resolution

• Users have a basic understanding of DIDs and cryptographic tokens

1.3 Constraints

• Maintain compatibility with existing DID resolvers

• Design for security and scalability

2. Architectural Overview

2.1 Design Philosophy

AXES Connect follows a modular, scalable, and secure architecture. It provides a comprehensive set of tools for managing DIDs, credentials, and TBAs while maintaining flexibility for integration with various blockchain and decentralized systems.

3. Component Architecture

3.1 DID Management Module

Responsibilities:

• Register DID: Create a new DID based on a provided public key

• Resolve DID: Retrieve the DID document associated with a given DID

• Get DIDs: Retrieve a list of DIDs associated with a specific address

3.2 Credential Management Module

Responsibilities:

• Issue Credentials: Create and associate credentials with a given DID

• Revoke Credentials: Revoke a credential associated with a DID

• Verify Credentials: Verify the validity of a credential for a given DID

3.3 Cryptographic Token Module

Responsibilities:

• Issue JWZ: Issue a JSON Web Token (JWT) for a given DID

• Verify JWZ: Verify the authenticity of a JSON Web Token for a DID

• Verify Signature: Verify the digital signature of a DID

3.4 TBA Management Module

Responsibilities:

• Create TBA: Generate a new Token Bound Account

• Link TBA: Associate a TBA with a specific token (e.g., NFT)

• Transfer TBA: Handle the transfer of TBA ownership

• Resolve TBA: Retrieve TBA information based on token or address

3.5 Storage and Blockchain Interaction Layer

Responsibilities:

• Store DID Documents and credentials in decentralized storage

• Interact with blockchain networks for on-chain operations

• Handle transaction signing and broadcasting
