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.
