Summary of Changes

Hello @Hanssen0, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly expands the project's capabilities by introducing a dedicated package for DID CKB operations. It lays the groundwork for managing decentralized identities on the CKB network, providing essential functions for their lifecycle and integration with existing core components. The inclusion of comprehensive examples will aid developers in quickly adopting these new features.

Highlights

New DID CKB Package: Introduced a new package, @ckb-ccc/did-ckb, which provides core functionalities for Decentralized Identifiers (DIDs) on the CKB blockchain.
DID CKB Script Integration: Added the KnownScript.DidCkb definition to the @ckb-ccc/core package, including specific configurations for both Mainnet and Testnet environments.
DID Operations: Implemented functions for basic DID CKB operations: createDid to mint new DIDs, destroyDid to remove them, and transferDid to change their ownership.
Example Usage: Included new example scripts in packages/examples demonstrating how to create, destroy, and transfer DID CKB cells, including an example for creating a DID with a local ID and PLC authorization.
Dependency Updates: Updated dependencies across packages/examples, packages/playground, and packages/shell to integrate the new @ckb-ccc/did-ckb package and related cryptographic libraries (@noble/curves, @noble/hashes).

Code Review

This pull request introduces the new @ckb-ccc/did-ckb package, providing essential functionalities for Decentralized Identifier (DID) operations on CKB. The changes are comprehensive, including the core logic for creating, transferring, and destroying DIDs, along with necessary codec implementations for data serialization. The addition of DidCkb to KnownScript and its configurations for both mainnet and testnet are correctly implemented.

The new package is well-integrated into the existing ecosystem, with updates to the shell package, playground, and documentation configuration. The inclusion of clear and practical examples is particularly helpful, demonstrating the usage of the new DID features effectively.

I've found one minor issue regarding the package description in package.json. Otherwise, the code is well-structured, clean, and follows the project's conventions. Great work on this feature!

packages/did-ckb/package.json

+{
+  "name": "@ckb-ccc/did-ckb",
+  "version": "0.0.0",
+  "description": "UDT",


The package description is currently "UDT", which appears to be incorrect for a package related to DIDs. To avoid confusion for developers using this package, it should be updated to accurately reflect its functionality. A more descriptive text, such as "CCC's support for DID on CKB", would be more appropriate.

Suggested change

"description": "UDT",

"description": "CCC's support for DID on CKB",
