 The chain of tasks and their ZK-proofs are recorded **on the IoTeX blockchain**, making them accessible for dApps. The actual data, uniquely referenced by the on-chain tasks, remains available for full off-chain verification.
 
 This architecture ensures secure, reliable, and scalable data processing, allowing DePIN dApps to act on verified real-world facts to trigger blockchain-based incentives.

+## Getting Started
+
+### For Embedded Developer
+
+[<u>ioID-SDK</u>](https://github.com/iotexproject/ioID-SDK) repo provides SDK for DePIN hardwares to connect W3bstream and IoTeX ecosystem
+
+
+### For Project Builder 
+
+[<u>Build a custom zk prover for W3bstream</u>](./docs/DEVELOPER_GUIDE.md)
 
-## Running nodes
- > ⓘ **Note**: Joining the W3bstream network as a sequencer or prover node is currently unavailable. Stay tuned for updates in future releases. [Follow us on X](https://x.com/iotex_dev).

+ - Storage: [<u>./datasource</u>](./datasource/) folder contains [<u>documentation</u>](./datasource/README.md)  and existing implementations W3bstream can suppport. 
 
-## Contract Deployments
+ - ZK Engine: ZK Service needs to support [Protobuf interface](./vm/proto/vm.proto) to communication with ZK Node
