Developers

By leveraging W3bstream, developers can efficiently process and validate device data before committing proofs of physical work to the blockchain, ensuring integrity of data processing and reducing on-chain computation costs.

This guide outlines the steps necessary to integrate W3bstream into your DePIN project, from setting up a local development environment to deploying your configuration on the IoTeX blockchain. To use W3bstream as the off-chain compute layer in a DePIN project, developers should follow these steps:

1. Run a local W3bstream node: Set up and run a W3bstream node on your local machine to facilitate the development and testing process.

2. Build the prover logic: Develop the logic that processes and verifies device data, ensuring it meets the necessary criteria before being sent to the blockchain.

3. Create a W3bstream configuration file: Compile a configuration file that includes your prover code, specifying how W3bstream should handle and process incoming data.

4. Test the W3bstream prover locally: Validate your prover logic and configuration file by running tests locally to ensure everything functions correctly.

5. Deploy the W3bstream configuration to the IoTeX blockchain: Once testing is complete, deploy your configuration to the IoTeX blockchain, enabling your DePIN project to leverage W3bstream's off-chain compute capabilities in a live environment.

Prerequisites

1. ioctl CLI

Ensure that you have installed the IoTeX ioctl client before proceeding:

curl https://raw.githubusercontent.com/iotexproject/iotex-core/master/install-cli.sh | sh

1. Testnet endpoint

ioID is currently on testnet. Ensure you have configured ioctl with the IoTeX testnet endpoint:

ioctl config set endpoint api.testnet.iotex.one:443

->See more IoTeX RPC Endpoints

1. Test Tokens

Ensure you have some IOTX test tokens in your wallet balance
