This article gives insight into the basic functionality of a Fabric network, namely those of the channels. We get to know the importance of the channels and to understand the differences between system and application channel. In this meetup we adapt step by step the existing test-network with two application channels. Furthermore, we install a chaincode per channel and test it with the CLI. We get to know the needed tools like configtxgen or configtxlator and decode a *.

This contribution shows the different usage of a chaincode implementation. The article builds on the previous one of 23rd of October 2020 and demonstrates how an external CC Service can be used in comparison with an internal implied chaincode container. Furthermore, we dive deeper into the test-network as we look closer at the attached scripts to change between the organizations. We also learn how the docker-compose.yaml file is built-up. This contribution also gives a short insight into the so-called buildpacks.

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.

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.

This contribution gives you a first taste of the world of HLF 2.2.x. It shows how you can install an own development system on a Virtual Private Server (VPS - DigitalOcean Droplet). Furthermore, you get an overview of the provided test-network which is integrated in the fabric-samples. The samlinux newsletter service keeps you up-to-date automatically.
