It Chain

It Chain is an open-source, Go-based blockchain implementation organized into six independently operating components—transaction pool, consensus, blockchain, peer, authentication and iCode—that communicate through AMQP. Its modular design is intended to support domain-specific customization, and its repository provides installation and simple smart-contract tutorials.

Practical overview

When it fits

Use It Chain for learning, simulation or development experimentation when a modifiable blockchain architecture and simple smart-contract tutorials are relevant.

Who it is for

  • Developers exploring how a modular blockchain is structured
  • Teams prototyping domain-specific or private blockchain designs
  • Learners following the repository's simple iCode smart-contract tutorials

Documented uses

  • Study how transaction, consensus, peer, authentication and chain components are separated
  • Explore communication between blockchain components through an AMQP event bus
  • Adapt the documented component architecture for a domain-specific prototype
  • Follow a tutorial for a simple iCode smart contract
Before you choose

Requirements & limits

  • The project is written in Go and lists Go 1.9+, Docker 17.12.0+ and RabbitMQ 3.7.7+ as requirements.
  • Its core components communicate through AMQP.
  • The project README explicitly says it should not be used in production at this time.
  • The source code is licensed under Apache-2.0.

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

Review it-chain requirements and smart-contract tutorials

Prepare to follow the repository’s installation and simple iCode smart-contract tutorials.

Before you start

  • Go 1.9 or later
  • Docker 17.12.0 or later
  • RabbitMQ 3.7.7 or later

Steps

  1. Review the repository README and confirm that the listed Go, Docker, and RabbitMQ requirements are available.

  2. Open the INC_INTEGER_TUTORIAL or BANK_TUTORIAL linked from the README.

  3. Follow the chosen tutorial for installation and its simple iCode smart-contract example.

Expected outcome

A tutorial-guided installation and simple smart-contract example, as described by the repository.

Guide limitations

  • The README says it-chain should not be used in production at this time.
  • The README points to the tutorial documents but does not include their detailed commands or steps.
