dispatchSubspaceCreateToChain

dispatchSubspaceCreateToChain(chainSpace, creatorUri, authorAccount, count, parent, signCallback): Promise<object>

Dispatches a Sub-ChainSpace creation transaction to the CORD blockchain.

Parameters

• chainSpace: IChainSpace

The ChainSpace object containing necessary information for creating the ChainSpace on the blockchain.

• creatorUri: did:cord:3${string}

The DID URI of the creator, used to authorize the transaction.

• authorAccount: CordKeyringPair

The blockchain account used for signing and submitting the transaction.

• count: number

• parent: space:cord:${string}

• signCallback: SignExtrinsicCallback

The callback function for signing the transaction.

Returns

Promise<object>

A promise resolving to an object containing the ChainSpace URI and authorization ID.

authorization

authorization: AuthorizationUri

uri

uri: SpaceUri

Remarks

Responsible for creating a new ChainSpace on the blockchain. It first checks if the ChainSpace with the given URI already exists to avoid duplicates. If not, it constructs and submits a transaction to create the ChainSpace. The transaction requires authorization from the creator and is signed by the specified author account.

Example

const chainSpace: IChainSpace = {
  // ... initialization of chainSpace properties ...
};
const creatorUri: DidUri = 'did:cord:creator_uri';
const authorAccount: CordKeyringPair = // ... initialization ...
const signCallback: SignExtrinsicCallback = // ... implementation ...

try {
  const result = await dispatchSubspaceCreateToChain(chainSpace, creatorUri, authorAccount, signCallback);
  console.log('ChainSpace dispatched with URI:', result.uri);
} catch (error) {
  console.error('Error dispatching ChainSpace:', error);
}

Throws

• Thrown when there’s an error during the dispatch process.
