Klayr module which implements on-chain logic for Klayr decentralized identifiers (DIDs)
About Klayr
Klayr is an open-source blockchain application platform written in Javascript, designed to bridge the gap between accessibility and web3 adoption. Learn more about Klayr from their official website, as well as it's public GitHub Repository.
About did:klayr
Method
did:klayr
is a DID method specifically designed for Klayr sidechain, which outlines syntax, data model, and operations that adheres to W3C Decentralized Identifiers (DIDs) Specification.
A did:klayr
DID consist of a method, chainspace, namespace, and unique-id that suitable for specific, tailored, self-sovereign identity use case. An example of a did:klayr
identifier, is as follows:
did:klayr:enevti:address:kly9gxy8ua2n5sj7eqvtp554hvce8m39sy39sjwzu
Please refer to the did:klayr method spec draft for further explanation. As its still in under active development, community contribution will be much appreciated.
Module Architecture
Getting Started
Sidechain Setup
Since this tool is tailored for Klayr-based sidechains, you need to start by setting up a blockchain client. You can find guidance on configuring your blockchain environment in the official Klayr Documentation, as well as in Klayr Discord #dev-discussion channel
Installation
npm install --save @klayr-did/klayr-did-module
Module Configurations
Under your blockchain config folder, please specify required configurations for did module:
{
"<...other_config>": "",
"modules": {
"did": {
"chainspace": "enevti",
"autoCreateAddressDID": true
},
"<...other_modules>": ""
}
}
Those configuration can be explained as follows:
- chainspace: (REQUIRED) chainspace to be used by your chain's DID.
did:klayr
require a chainspace to be defined, as it's format is as follows:did:klayr:{chainspace}:{namespace}:{unique-id}
- autoCreateAddressDID: (default to true) whether you want to enable auto address DID creation. If this option is enabled, an address DID will be automatically created when the address sends any transaction.
Register Module
Last step is to register did module to your blockchain app. Add this code to ./src/app/modules.ts
as follows:
import { DidModule } from '@klayr-did/klayr-did-module';
export const registerModules = (app: Application, method: KlayrMethod): void => {
// your other module registration
app.registerModule(new DidModule()); // add this
};
