What is IoTeX?

IoTeX is the modular infrastructure for DePIN projects to deploy in full or integrate modules into existing frameworks. Please visit IoTeX homepage official website to learn more about IoTeX network.

What is DePIN?

DePIN stands for Decentralized Physical Infrastructure Networks, a new approach to building and maintaining physical world infrastructure. This infrastructure can range from WiFi hotspots in wireless networks to solar-powered home batteries in energy networks. DePINs are developed in a decentralized manner by individuals and companies globally, making them accessible to everyone. In return, contributors receive financial compensation and an ownership stake in the network they’re building and the services they provide through token incentives. DePINs are enabled by widespread internet connectivity and advancements in blockchain infrastructure and cryptography. To learn more about DePIN, please visit What is DePIN?.

Explore DePIN Projects?

DePIN Scan is the go-to explorer for DePIN projects. DePIN Scan tracks crypto token prices, real-time device data, and offers a variety of views for DePIN projects.

Building the source code

Minimum requirements

Compile

Download the code to your desired local location (doesn't have to be under $GOPATH/src)

git clone git@github.com:iotexproject/iotex-core.git
cd iotex-core

If you put the project code under your $GOPATH\src, you will need to set up an environment variable

export GO111MODULE=on
set GO111MODULE=on (for windows)

Build the project for general purpose (server, ioctl) by

make

Build the project for broader purpose (server, ioctl, injector...) by

make all 

If the dependency needs to be updated, run

go get -u
go mod tidy

If you want to learn more advanced usage about go mod, you can find out here.

Run unit tests only by

make test

Build the docker image by

make docker

Run iotex-core

Start (or resume) a standalone server to operate on a blockchain by

make run

Restart the server from a clean state by

make reboot

If "make run" fails due to corrupted or missing state database while block database is in normal condition, e.g., failing to get factory's height from underlying DB, please try to recover state database by

make recover

Then, "make run" again.

Use CLI

Users could interact with iotex blockchain by

ioctl [command]

Refer to CLI document for more details.
