Worker Integration: Data Availability Sample Integration

Prerequisites: Clone the CrestalJS SDK repository

# Clone the SDK
git clone https://github.com/crestalnetwork/crestal-js-sdk.git

# Install and build
cd crestal-js-sdk
npm install # or yarn
npm run build # or yarn build

1. Create a New Project

Visit the Crestal Dashboard.
Select New Project.
For testing purposes, type /helloworld into the AI assistant. The assistant will generate a HelloWorld target performance for you to try Crestal.

2. Run the Event Listener

Run the event listener for your desired network. In this example, we use Berachain.

Listeners are available for all supported networks:

Running the Listener

npx ts-node utils/examples/listenToBerachainBartio.ts

Expected Output Example

When you run the event listener, it listens for incoming RequestProposal events on the specified network. These events contain detailed information about the proposal request, including the projectID, requestID, and parameters like chainRequestParam that describe the required data availability (DA) configuration.

3. Submit a Proposal

The chainRequestParam field in the RequestProposal event provides all the necessary information required to craft and submit a proposal. The proposal we are sending now for test purposes doesn’t have to match the request exactly, as they are dummy values, but it must conform to the required format. For detailed guidance about proposals, refer to the Solver Integration Walkthrough.

We are going to submit a proposal with private worker, this means that we mention a specific worker that will be the only one who can make the deployment. To do this, we’ll use utils/examples/submitPrivateProposalExample.ts.

Populate Required Variables:

solver_address: Your account address as a solver.
project_id: Use the project_id from the event listener output.
request_id: Use the request_id from the event listener output.
privateKey: The private key for the solver_address.
worker_address: The address of the worker handling the deployment. This can be the same as the solver address.

Use the following command to run the script and submit the proposal:

npx ts-node utils/examples/submitPrivateProposalExample.ts

Once submitted, the proposal will appear on the Crestal frontend.

Here’s an example proposal data with populated data:

{
  "project_id": "0x2835c205f8f558febf22804eb****************1dce1ff558b21ad094f13b7",

      }
    }
  ]
}

4. Approve the Proposal for Deployment

Approve the proposal from the frontend.
Ensure the event listener is running to detect the following events:
- AcceptDeployment
- RequestPrivateDeployment

Example Output

Event listener started successfully.

5. Submit the Deployment Request to Backend

The deployment request must be submitted to both the backend and the smart contract. For private proposals with a private worker, the request only needs to be submitted to the backend.

Deployment Data

The Deployment type represents the data structure required for submitting deployment requests. It also contains the proposal itself. The deployment details are also included in this type, but they are only required when submitting the proof of deployment.

The requestId and projectId can be extracted from the RequestPrivateDeployment event.

const deploymentData: Deployment = {
  request_id: requestId,
  project_id: projectId,
  chain_id: chainId,
  worker_address: workerAddress,
  solver_address: workerAddress,
  status: 'deploying',
  proposal: proposal
};

export interface Deployment {
    request_id: string; // Required field, unique ID for the deployment request
    chain_id: number;
    project_id?: string; // Optional field, project ID from the Crestal website
    worker_name?: string; // Optional field, name of the worker
    worker_address: string; // Required field, worker's Ethereum address in hex format
    solver_address: string; // Required field, solver's Ethereum address in hex format
    status: DeployStatus; // Required field, current status of the deployment
    proposal_hash?: string; // Optional field, hash of the proposal
    proposal?: object; // Optional field, serialized JSON string of the proposal
    deployment_details?: DeploymentDetails ; // Optional field, serialized JSON string of the deployment details
    }

Deployment Status Types:

init
pick_up
deploying
deployed
generating_proof
generated_proof

Proposal Data

For testing purposes, the predefined proposal from the SDK example we are using looks like this:

const proposal = {
  chain_id: chainId,
  da_name: "Avail",
  network_type: "Testnet",
  gas_token: "ETH",
  avg_cost: 3.2,
  max_throughput: 10.5,
  latency: 0.3,
  finality_time: 2.0,
  geo_coverage: 8,
  grants_available: false,
  number_of_projects: 1,
  uptime: 10,
  block_time: 10,
  total_transactions: 1000000002,
  total_blocks: 1000000003,
  number_of_nodes: 5000,
  cost_per_transaction: 0.3,
  cost_per_mb: 0.2,
  error_rate: 0.02,
  init_cost: 100,
  maintenance_cost: 20
};

However, in a real-world scenario, the actual data for the proposal can be extracted from the RequestPrivateDeployment event’s decodedProposal field. Here’s an example:

decodedProposal: {
    id: 28049,
    da_name: 'Avail',
    chain_id: 80084,
    project_id: '0xeed9af033fecec172ba5d55687960413e9c199177d26440f0b9e8d65b0c480cd',
    network_type: 'Testnet',
    gas_token: 'ETH',
    avg_cost: 3.2,
    max_throughput: 10.5,
    finality_time: 2,
    geo_coverage: 8,
    number_of_projects: 1,
    uptime: 10,
    block_time: 10,
    total_transactions: 1000000002,
    total_blocks: 1000000003,
    number_of_nodes: 5000,
    cost_per_transaction: 0.3,
    cost_per_mb: 0.2,
    error_rate: 0.02,
    init_cost: 100,
    maintenance_cost: 20,
    worker_address: '0x1e22A1C3AB5DfbA41d61d546f39b08A43410caC8',
    type: 'DA',
    created_at: '2024-11-20T22:31:51.471797Z'
  }

This proposal is included in the proposal field from Deployment.

Submission

For this example, we are using the utils/examples/submitDeploymentExample script.

To submit the deployment request, populate the following fields:

workerAddress: The address of the worker you want to use for deployment.
privateKey: The private key associated with your worker’s address.
requestId: The request ID from the RequestPrivateDeployment event.
projectId: The project ID from the RequestPrivateDeployment event.

Then run the script:

npx ts-node utils/examples/submitDeploymentExample.ts

6. Update the Deployment Status

The deployment status needs can be updated by submitting requests to the backend. To achieve this, you can use the utils/examples/updateDeploymentExample script.

Updating the Status to `deployed`

Use the same projectId and requestId from Step 5. In the example, the status is set to deployed, indicating that the deployment has been successfully completed.

For the full list of possible statuses please check Step 5.

The run the command:

npx ts-node utils/examples/updateDeploymentExample.ts

Frontend Status Progression

After the status is updated to deployed, the frontend will automatically update the status to Generating Proof. This signifies that the deployment is complete and now awaits the submission of the Proof of Deployment.

8. Submit the Proof of Deployment

After completing the deployment, the next step is to submit the Proof of Deployment to both the backend and the blueprint smart contract.

Submitting to the Smart Contract

To submit to the smart contract, use the example from utils/examples/submitDeploymentProofContract.ts. The format that needs to be submitted is of type ProofOfDeploymentContract.

export type ProofOfDeploymentContract = {
  request_id: string;
  proposal_base64: string;
  expiration_date: number;
  worker_address: string;
  server_https_url?: string;
  server_http_url?: string;
  server_web_socket_url?: string;
  server_rpc_endpoint?: string;
  server_grpc_endpoint?: string;
  deployment_pick_up_time: number;
  deployment_deployed_time: number;
  description?: string;
  machine_info?: MachineInfo;
  service_info?: ServiceInfo;
};

export type MachineInfo = {
  mac_address: string;
  cloud_provider: string;
  unique_id: string;
};

export type ServiceInfo = {
  api_infos: APIInfo[];
};

export type APIInfo = {
  endpoint: string;
  method: string;
  request?: string;
  response?: string;
};

All this data is already predefined in the example. You just need to populate required variables:

projectaId: Use the projectId from Step 6.
requestId: Use the requestId from Step 6.
workerAddress: The address of the worker handling the deployment.
privateKey: The private key for the worker_address.

Run the script:

npx ts-node utils/examples/submitDeploymentProofContract.ts

Submitting to the Backend

To submit to the backend, we use the update backend endpoint and include the additional fields required for the proof of deployment.

The format is the Deployment type from Step 5, and we add the proof of deployment details to the deployment_details field as DeploymentDetails type.

  export type DeploymentDetails = {
    access_url: string;
    server_https_url: string;
    server_http_url: string;
    server_ws_url: string;
    server_wss_url: string;
    server_web_socket_url?: string;
    server_grpc_endpoint?: string;
    server_rpc_endpoint?: string;
    token: string;
  };

All this data is already predefined in the example. You just need to populate required variables:

projectId: Use the project_id from Step 6.
requestId: Use the request_id from Step 6.
workerAddress: The address of the worker handling the deployment.
solverAddress: The account address as the solver.
privateKey: The private key for the worker_address.

7. Deployment Completed

The deployment process is now fully completed. The Proof of Deployment has been submitted to both the backend and the smart contract, and all events have been processed successfully. Verify on the frontend that the deployment status reflects the completion, confirming that everything is finalized.
