IoT & Ethereum Integration
summary
An end-to-end demo shows a real-time IoT-to-blockchain pipeline: sensors (Ruby Tag on Raspberry Pi) push JSON to streamer canvas, an averaging accumulator computes seconds-over-threshold, and a Solidity escrow token plus chain monitor contract on Rinkeby testnet receives a single sampled penalty value. Tools used: Node.js library for streamer, MetaMask (private key export noted), Remix for deployment and time‑travel debugging, Java backend modules. Several components deploy and interoperate in the workshop, though the contract complexity and key‑handling reveal practical bugs and safety caveats.

- 1:36:23It Basically Works like this Data Stream that Whenever an Event Comes into the Contract It Will Start Activating Modules To Start Off from from this Get Events Module So Basically We Want To Send the I Guess We Want To Send the Overage So Here Is We Can Take this Kind of Sample if Modules What It's Called and We Trigger It if We Got Shipment Arrive and the Value That We Sample from that Time Point Is the Value Produced by the Overages Then We Take an Sm Core Value and Connect that to the Contract
