In this course, we will build blockchain concepts from the ground up. We will start with basic cryptography constructs, like hash functions and PKI encryption, to first build a solid base for understanding blockchain and appreciate its value. Then, we will explore the Hyperledger Fabric technology by IBM using hands-on development environment within your browser. This course is a great starting point for engineers looking to develop expertise in blockchain technology with Hyperledger Fabric specialty. In this course, you will deploy your own blockchain network, deploy chaincode on it and create an application that invokes your chaincode running in fabric network. You will also learn to manage fabric user identities in your application using wallets.

Here is the list of high-level steps being carried out when a transaction needs to be applied to the ledger.

1. Client App prepares the transaction signed by the user.
2. Client App connects to endorsing peers(as per endorsement policy) to collected signed endorsements on the transaction output. The peers simulate the transaction and return a signed endorsement.
3. Client App submits the endorsed  transaction to ordering service, which puts it into a valid block and distributes to all peers.

Please go through the detailed flow using this diagram:


In this lesson, we will take a look at high-level steps carried out in transaction processing.
