Dock SDK

Overview

The Dock SDK is an opensource library that powers Dock's SaaS API. It provides the credential management, cryptography, and blockchain storage features for Dock's supported credential variants:

• W3C VC JSON-LD ed25519 credential using StatusList 2021 for revocation targetted at interoperability
• W3C VC JSON-LD BBS credential using accumulators for revocation targetted at privacy
• W3C VC JSON-LD KVAC credential using accumulators for revocation allowing monetization of credentials

Most of the SDK is written in JavaScript / TypeScript with safety-critical code written in Rust. The SDK depends on the Arkworks math library.

Monorepository Packages

Features five packages, such as

• @docknetwork/credential-sdk - An API-agnostic Javascript library for working with Verifiable Credentials, DIDs, Claim Deduction, and more.
• @docknetwork/dock-blockchain-api - A Javascript library built with PolkadotJS, for use with the [Dock Substrate Node] (https://github.com/docknetwork/dock-substrate) or our public main/test networks.*
• @docknetwork/dock-blockchain-modules - A JavaScript library designed for handling credential SDK elements (DIDS, Accumulators, etc) on the Dock blockchain.
• @docknetwork/cheqd-blockchain-api - A Javascript library built atop of @cheqd/sdk that allows to interact with the Cheqd blockchain.
• @docknetwork/cheqd-blockchain-modules - A JavaScript library created for managing credential SDK components such as DIDs, accumulators etc on the Cheqd blockchain.

You are welcome to explore the tutorials and examples to get a basic understanding.

In essence, the architecture is structured as follows:

• The fundamentals of VC, including types, cryptography, and abstract modules, are housed in @docknetwork/credential-sdk.
• Specific implementations for the Dock and Cheqd blockchain modules can be found in @docknetwork/dock-blockchain-modules* and @docknetwork/cheqd-blockchain-modules, respectively.
• Basic blockchain connectors for the Dock and Cheqd blockchain are available through @docknetwork/dock-blockchain-api* and @docknetwork/cheqd-blockchain-api.

Deprecated Features

• Dock blockchain will be sunset in 2025. More information.

Some features of the SDK are deprecated and will be removed in a future release:
