A new book, Getting Started with Artificial Intelligence, provides insight on the practical aspects of implementing AI in the enterprise.
Build a blockchain network
Create your first blockchain network using Hyperledger Composer
Blockchain is a secure, distributed, and open technology that is lowering costs, speeding up processes, and building a new level of trust in transactional applications. This developer journey will get you started with blockchain by showing you how to build a blockchain network using Hyperledger Composer.
Blockchain is changing the way businesses conduct transactions. This secure, distributed, and open technology is lowering costs, speeding up processes, and building a new level of trust in secure interactions.
When something as big as blockchain emerges, developers who understand and can implement the technology are in the driver’s seat. But first you have to learn it.
In this developer journey, the first in a series of “hello world” blockchain journeys, you’ll learn how to build a blockchain network using Hyperledger® Composer. You’ll create a Business Network Archive (BNA) file that enables you to define a model; for example, the participants, tradeable assets, and allowable transactions. You’ll then deploy the network on Hyperledger Fabric, the blockchain framework implementation hosted by The Linux Foundation®. For this journey, you’ll run Hyperledger Fabric™ locally.
You’ll discover how useful a tool Hyperledger Composer can be. It gives you the ability to quickly model your current business network, including your existing assets and the transactions related to them. As part of your business network model, you’ll define the transactions that can interact with assets. Business networks also include the participants who interact with them, each of which can be associated with a unique identity, across multiple business networks.
This is your chance to climb on the blockchain train and build the skills that every business will need. Complete this developer journey, watch for future blockchain journeys, and make yourself indispensable.
- Install Hyperledger Composer development tools.
- Start Hyperledger Fabric.
- Generate the Business Network Archive file.
- Deploy the Business Network Archive using Composer Playground.
- (Alternative method) Deploy the Business Network Archive on Hyperledger Composer running locally.
