Please note that the Platform is updated often, and the screen shots in this tutorial may not exactly match the ones you see. View image at full size. Check the Glossary for Hyperledger Fabric for any unfamiliar terms. The next step is to create a channel called "fabcar. A channel allows peers associated with that channel to see each other's transactions, but peers outside the channel cannot see these transactions. It provides a level of transaction privacy and security among the peers.

Each channel could have same or different chaincode instantiated, based on business needs. After the channel is created, the next step is to install the chaincode. We'll use the chaincode from the "fabcar" sample application. Click the JSON button, and a new tab will open. To run your application on the IBM Blockchain Platform, you need to make few changes to the fabcar sample.

Start by copying the extractCerts. On Windows, you may need to install the Windows Build Tools if you get errors: Make a directory called network in the fabcar directory, and then run extractCerts.

This will create a CA certificate and a peer certificate in the given path, or by default in the. It also outputs three URLs to be used next to enroll users peer-url, peer-event-url, and orderer-url. It will generate a certificate in the given wallet path for the user provided.

Before you can query and update the ledger, you need to run a setup transaction to populate the ledger with some sample data. Make a copy of the invoke. Make sure the copy is in the same folder as the original file. Then make the following changes to the invokeNetwork. Make a copy of the query. Then make the following changes to the queryNetwork.
