Hyperledger Fabric (HLF) Chaincode / Smart Contract in Fabric 2.2.x

This article delivers insights into the world of HLF 2.2.x. The talk starts with the concept of the smart contract and shows how it is linked to Fabric. Furthermore, the “chaincode lifecycle” process is shown which is newly introduced in Fabric Version 2. Finally, the differences to version 1 are presented. With an hands-on example the existing chaincode ABstore is installed in a test-network of fabric-samples. The upgrade process is also addressed as well as how to change the chaincode afterwards.

Understanding Fabric 2.2.x - Episode no 01

Introduction In the blockchain world there are basically two types of blockchain - the public and the private blockchain. Hyperledger Fabric (HLF) can be assigned to the private blockchain world. In this article I would like to explain how you get started with this technology. In a permissionless (public) blockchain, on the one hand, virtually anyone can participate and every participant is anonymous. On the other hand, permissioned (private) blockchains operate amongst a set of known, identified and often verified participants who act under a governance model that yields a certain degree of trust.
