wtf is pulsegrid?

PulseGrid is a blockchain project built for a hackathon called the BOT Chain Builder Challenge. It is aimed at a category called DePIN, short for decentralized physical infrastructure, where real world devices report data and get paid automatically for doing so. In this system, devices sign and stream small pieces of telemetry data, and that data gets recorded on the blockchain every fixed time interval called an epoch, without the device itself needing to pay any transaction fees. An automated program called the Settlement Agent then checks each device every interval and either pays it a small amount of stablecoin for delivering its data, or penalizes it by taking a portion of its posted deposit if it failed to deliver. The important design choice is that this automated agent does not have final say: a set of smart contracts recalculates the correct payment or penalty directly from the on chain proof of what data actually arrived, so a broken or dishonest agent cannot overpay, wrongly penalize, or pay twice for the same interval. Anyone can register as an operator and deploy their own simulated device straight from a web browser, connect a crypto wallet, and start streaming without installing anything locally. A companion web dashboard, built with Next.js, shows live payment and penalty history, current device status, and reputation scores pulled directly from the blockchain, so nothing shown is fake or pre-recorded. There is also an optional add on that uses an AI model to write plain language notes about a device's health, but the project is clear that this AI layer never influences an actual payment decision. Under the hood, the smart contracts are written in Solidity and tested with Foundry, while the automated settlement agent is written in Go. The project is aimed at developers interested in blockchain infrastructure, automated agents, or hackathon style proof of concept builds, and it requires Foundry, Go, and Node.js to run and test locally.
