DecentralChain (DCC)Install

Overview

This node interacts with the DecentralChain (DCC) blockchain network, providing various utilities including querying aliases associated with a blockchain address. Specifically, the Utility - Get Aliases operation fetches all aliases registered for a given DCC address.

This node is useful in scenarios where you need to resolve or list human-readable aliases linked to blockchain addresses, which can simplify identification and referencing of accounts on the DCC network. For example, a user might want to display all known aliases for an address in a wallet application or verify alias ownership before performing transactions.

Properties

Output

The output JSON contains the response from the DCC node API endpoint /alias/by-address/{address}, which returns the list of aliases associated with the specified address.

Typical structure includes:

• An array of alias objects, each containing details such as:
  • alias (string): The alias name.
  • address (string): The blockchain address the alias belongs to.
  • Other metadata fields as provided by the DCC API.

Additionally, the output includes a debug object with metadata about the operation, such as:

• operation: The performed operation (getAliases).
• endpoint: The API endpoint called.
• baseUrl: The base URL used.
• parameters: Input parameters like the address.
• timestamp: When the request was made.

Example output snippet (simplified):

{
  "aliases": [
    {
      "alias": "myalias",
      "address": "DCC3...xyz"
    },
    {
      "alias": "anotheralias",
      "address": "DCC3...xyz"
    }
  ],
  "debug": {
    "operation": "getAliases",
    "endpoint": "/alias/by-address/{address}",
    "baseUrl": "https://nodes.decentralchain.io",
    "parameters": {
      "address": "DCC3...xyz"
    },
    "timestamp": "2024-06-01T12:00:00Z"
  }
}

No binary data output is produced by this operation.

Dependencies

• Requires access to a DecentralChain node API endpoint, either via:

  • A configured API key credential (optional).
  • Or the Base URL property specifying the node URL.

• The node uses HTTP requests to communicate with the DCC REST API.

• No additional external services or environment variables are required specifically for this operation.

Troubleshooting

• Common issues:

  • Invalid or unreachable Base URL: Ensure the Base URL is correct and the node is accessible.
  • Address parameter missing or invalid: The address must be a valid DCC blockchain address.
  • Network connectivity problems may cause request failures.

• Error messages:

  • If the address is invalid or not found, the API may return an error or empty result.
  • HTTP errors (e.g., 404, 500) indicate issues with the node endpoint or request.
  • JSON parsing errors could occur if the API response is malformed.

• Resolution tips:

  • Verify the address format before running the node.
  • Check network connectivity and API availability.
  • Use the debug information in the output to trace request details.
  • If using credentials, ensure they are correctly configured and have necessary permissions.
