Lightweight Customizable Chain For All

The it-chain is an easily modifiable block chain that can fit into any domain. To make it easier to customize, we have divided the it-chain into several independent components and minimized dependencies between them.

It should not be used in production at this time.

Architecture of it-chain

The it-chain is implemented as six independently operating core components(txpool, Consensus, Blockchain, Peer, Authentication, iCode), each communicating via the Asynchronous Message Queue Protocol (AMQP). AMQP is an event bus connector that generates and distributes events for internal core components according to external messages coming into the gateway, and each core component receives and operates events that it has already registered.

A more detailed explanation is given below.


How to install it-chain and run simple icode(smartContract) can be found in the tutorial docs.


  • Go-lang >= 1.9
  • Docker >= 17.12.0
  • Rabbitmq >= 3.7.7
