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.

### What is public key cryptography?
Public key cryptography is a cryptographic system used for the encryption/decryption of data. It is not one way like a hash function, meaning that the data, once encrypted, can be decrypted if you have the required key.

You start by generating a special, related pair of keys. These keys can be generated in a pair only. They are output from single execution of a key generation algorithm.
