Understand the project

Practical overview

When it fits

Use IOST when a project needs the IOST blockchain implementation, JavaScript smart-contract execution or a local node workflow for application development and testing.

Who it is for

  • Blockchain developers building applications for the IOST ecosystem
  • Node operators working with the IOST blockchain implementation
  • Teams testing IOST applications on a local development network
  • Developers packaging an IOST node as a Docker image

Documented uses

  • Run an IOST blockchain node
  • Build JavaScript smart contracts for IOST
  • Create a local network for application integration testing
  • Package the node implementation as a Docker image
  • Develop high-throughput decentralized applications using IOST infrastructure
Before you choose

Requirements & limits

The repository is publicly accessible and identified with an LGPL-3.0 license. The documented build environment is Ubuntu 22.04 or later with Go 1.20 or later and x64 architecture.

  • The node is implemented in Go, so Go-based build tooling is part of the documented environment.
  • JavaScript smart-contract execution is provided through the integrated V8 engine.
  • The V8 CGO dependency limits the documented node environment to x64 architecture.
  • The repository documents separate options for a local binary, a local development network and a Docker image.
  • The project describes high throughput, rapid finality and free transactions supported through staking for gas.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up an IOST local development workflow

Prepare the documented IOST build and local development options for testing blockchain applications.

Before you start

  • Ubuntu 22.04 or later
  • Go 1.20 or later
  • x64 architecture
  • A local checkout of the IOST go-iost repository

Steps

  1. Build the local IOST binary with the command below.

    Documented command
    make build

  2. Start a local development network with the command below.

    Documented command
    make debug

  3. Build a Docker image with the command below when a containerized node package is required.

    Documented command
    make image

Expected outcome

A locally built IOST node, a local development network, or a Docker image, depending on the selected documented step.

Guide limitations

  • The repository states that the V8 JavaScript engine requires x64 architecture.
  • These documented steps cover building and local development setup; they do not describe a complete application deployment workflow.
