processProtectedData

Allows processing a protected dataset through use of a specified iExec application.

IMPORTANT

You must ensure this application has authorization to use the protectedData. You may grant this permission using the grantAccess method.

Usage

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    maxPrice: 10,
    args: 'arg1 arg2',
    inputFiles: ['https://example.com/file1', 'https://example.com/file2'],
    secrets: {
      1: 'secret1',
      2: 'secret2',
    },
  });

Parameters

import { type ProcessProtectedDataParams } from '@iexec/dataprotector';

protectedData Required *

Type: AddressOrENS

The ETH address or Ethereum Name Service (ENS) reference for the protected data you wish the app to process.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
  });

app Required *

Type: AddressOrENS

The ETH address or Ethereum Name Service (ENS) address for the iExec application to process the protected data.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
  });

userWhitelist Optional

Type: Address

If access to the protected data is granted to a group of users via a whitelist contract, you must use this userWhitelist parameter. The value should be the whitelist contract address that has access to the protected data.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    userWhitelist: '0x656def...',
  });

maxPrice Optional

Type: number

The maximum price (in nRLC) that a requester is willing to pay for each task related to processing the protected data. It is the sum of the application price, dataset price, and workerpool price per task.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    maxPrice: 10,
  });

args Optional

Type: string

Set of execution arguments for the application.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    args: 'arg1 arg2',
  });

DANGER

Do not use this to provide any sensitive information to the application. All arguments passed this way are visible in plain text using the iExec blockchain explorer.

inputFiles Optional

Type: string[]

A set of URLs representing the input files required for application execution.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    inputFiles: ['https://example.com/file1', 'https://example.com/file2'],
  });

secrets Optional

Type: Record<number, string>

A set of requester secrets necessary for the application's execution. This is represented as a mapping of numerical identifiers to corresponding secrets stored in the secrets manager needed for the application's execution.

Secrets are accessible during the application's execution as environment variables. For more details, see Access requester secrets.

const processProtectedDataResponse = await dataProtectorCore.processProtectedData({
  protectedData: '0x123abc...',
  app: '0x456def...',
  maxPrice: 10,
  secrets: { 
    1: 'secret1',
    2: 'secret2',
  },
});

workerpool Optional

Type: AddressOrENS | 'any'
Default: prod-v8-bellecour.main.pools.iexec.eth

The ETH address or Ethereum Name Service (ENS) address for the iExec workerpool. It's the confidential computer on which the iExec application will run.

TIP

iExec currently offers a production workerpool located at the Ethereum Name Service (ENS) address prod-v8-bellecour.main.pools.iexec.eth. This is the default workerpool for running confidential computations on the iExec platform.

If you don't specify a workerpool preference, 0x0000000000000000000000000000000000000000 represents any randomly available workerpool.

const processProtectedDataResponse =
  await dataProtectorCore.processProtectedData({
    protectedData: '0x123abc...',
    app: '0x456def...',
    workerpool: '0xa5de76...',
  });

onStatusUpdate Optional

Type: OnStatusUpdateFn<ProcessProtectedDataStatuses>

Callback function to be notified at intermediate steps.

const processProtectedDataResponse = await dataProtectorCore.processProtectedData({
  protectedData: '0x123abc...',
  app: '0x456def...',
  onStatusUpdate: ({ title, isDone }) => { 
    console.log(title, isDone); 
  },
});

You can expect this callback function to be called with the following titles:

'FETCH_PROTECTED_DATA_ORDERBOOK';
'FETCH_APP_ORDERBOOK';
'FETCH_WORKERPOOL_ORDERBOOK';
'PUSH_REQUESTER_SECRET';
'REQUEST_TO_PROCESS_PROTECTED_DATA';
'CONSUME_TASK';
'CONSUME_RESULT_DOWNLOAD';
'CONSUME_RESULT_DECRYPT';

Once with isDone: false, and then with isDone: true

Return value

import { type ProcessProtectedDataResponse } from '@iexec/dataprotector';

taskId

string

A unique identifier associated with a task currently running on the iExec Bellecour side chain. You may monitor task execution with the iExec blockchain explorer.
