DecentralChain (DCC)Install

Overview

This node provides various operations to interact with the DecentralChain (DCC) blockchain ecosystem. Specifically, for the Utility resource and Generate Address operation, it generates a blockchain address derived from a given public key by querying the configured DCC node API.

This is useful when you have a public key and want to obtain the corresponding DCC address without manually computing it. For example, after generating or importing a public key externally, you can use this node to get the associated address to send or receive tokens on the DCC network.

Practical scenarios include:

• Deriving an address from a public key during wallet creation or import.
• Verifying that a public key corresponds to a valid address on the DCC blockchain.
• Preparing transaction recipients by converting public keys to addresses.

Properties

Output

The output JSON contains the response from the DCC node API endpoint /addresses/publicKey/{publicKey}. This typically includes the generated address corresponding to the provided public key.

Example output structure (simplified):

{
  "address": "DCC1qxyz...abc",
  "publicKey": "base58-or-hex-encoded-public-key",
  "additionalInfo": { ... }
}

The exact fields depend on the DCC node API response but primarily provide the derived address.

No binary data output is produced by this operation.

Dependencies

• Requires access to a DecentralChain node API endpoint, either via:
  • An API credential providing a base URL, or
  • A manually specified Base URL parameter.
• The node uses HTTP requests to communicate with the DCC node API.
• No other external services or environment variables are strictly required for this operation.

Troubleshooting

• Invalid Public Key: If the public key is malformed or invalid, the API may return an error or empty result. Ensure the public key is correctly formatted and complete.
• Network Issues: Failure to reach the specified Base URL will cause request errors. Verify network connectivity and correct Base URL configuration.
• Missing Credentials: If credentials are expected but not supplied, the node falls back to the Base URL parameter. Make sure one of these is properly set.
• API Errors: The node surfaces API error messages in the output. Review these messages for clues about issues such as rate limits, invalid parameters, or server errors.
