 W3bstream is an integral part of the IoTeX network. It is a Layer-2 protocol orchestrated by the IoTeX Blockchain, dedicated to facilitating decentralized data processing in blockchain ecosystems. W3bstream nodes fetch raw data messages from supported data infrastructures and process them through project-specific ZK circuits to generate Zero-Knowledge (ZK) Proofs. These proofs are then dispatched to dApps on different blockchains and verified on-chain, enabling dApps to securely act on validated data insights. W3bstream enhances scalability and trust in blockchain applications, particularly where actions depend on the integrity of real-world data, such as in supply chain management, IoT, or any DePIN network where data authenticity triggers significant incentives on the blockchain.

 The diagram represents the main components of the software and how they interact with each other. Note that this reflects a single entity running a sequencer and a prover. However, there are many entities running nodes in the network. More on this later.
