Code Patterns

Everything you need to quickly solve real problems is compiled into a Code Pattern, with architecture diagrams, one-click deployment GitHub repositories, and pointers to essential docs.

Build your first blockchain application

Get started with this secure, distributed, open ledger technology by completing a journey series that shows you how to build a working blockchain app step by step.


Create and execute blockchain smart contracts

Use the Hyperledger Composer framework to create and execute smart contracts within a blockchain application built on Hyperledger Fabric.


Model FDA Foreign Supplier Verification Program requirements

In this journey, we capture the regulatory compliance logic for the FDA Foreign Supplier Verification Program in a smart contract deployed on a business network.


Build a blockchain network

Get started with blockchain technology by learning how to build a blockchain network using Hyperledger Composer.


Decentralized energy with Hyperledger Composer

Use Hyperledger Composer to create a decentralized energy network of residents, banks, and utility companies in which residents exchange energy for coins with other residents and utilities, and exchange coins for fiat currency with banks.


Run blockchain technology on a Linux mainframe

Discover how to use Hyperledger Composer and its tools, editors, and business network model to write, deploy, and test chaincode on LinuxONE.


Create a to-do list app using blockchain

Learn to perform traditional data store transactions with blockchain by implementing a web-based, to-do list app that enables you to browse, read, edit, add, and delete list items.


Deploy an asset-transfer app using blockchain

Learn app development within a Hyperledger Fabric network by creating an asset-transfer app to transfer marbles between multiple owners.
