Decentralized Infra for Connecting Smart Devices to Smart Contracts

W3bstream

Overview

W3bStream is a general framework for connecting data generated by devices and machines in the physical world to the blockchain world. In a nutshell, W3bStream uses the IoTeX blockchain to orchestrate a decentralized network of gateways (i.e., W3bStream nodes) that streams encrypted data from IoT devices and machines and generates proofs of real-world facts to different blockchains.

Arch

Run W3bstream node with prebuilt docker images

Make a path for w3bstream node. In the path, run the following command

curl https://raw.githubusercontent.com/machinefi/w3bstream/main/docker-compose.yaml > docker-compose.yaml

Edit the config in the yaml file if needed. Then run

docker-compose -p w3bstream -f ./docker-compose.yaml up -d

Your node should be up and running.

Please note: the docker images are hosted at GitHub Docker Registry

Access W3bstream Studio

W3bstream Studio is a web tool that allows W3bstream node operators to administrate their node, deploy and run applets, and explore data.

Visit http://localhost:3000 to get started. The default admin password is iotex.W3B.admin. Learn more from documentation.

Build docker image from code

If you are interested in diving into the code and run the node using a locally built docker, here is the steps of building the docker image from code.

Build docker images

make build_docker_images

Run server in docker containers

 make run_docker

Stop server running in docker containers

make stop_docker

Delete docker resources

make drop_docker

Interact with W3bstream using CLI

Please refer to HOWTO.md for more details.
