Hyperledger Fabric für Node.js Developers - 2021jsday.it
In his talk about Hyperledger Fabric for Node.js Developers Roland takes the attendees on a journey through the world of Hyperledger Fabric. He shows how a Node.js developer can write chaincode (smart contract) and interact with the network. With a CRUD application Roland demonstrates how fabric-contract-api is used to write a chaincode with Node.js. Furthermore, he will explain how an express.js REST application can interact with the Hyperledger Fabric network.
Hyperledger Fabric (HLF) / Attribute Based Access Control (ABAC) Node.js
This is the first session of the biweekly crowdcast session series about Hyperledger Fabric Developer with special focus on Node.js development. The session series shows a little bit of my own preparation process for the Hyperledger Fabric Developer certification. In this first session I would like to share how you can use the concept of attribute based access control (ABAC) in your chaincode, implemented with Node.js. Based on a simple chaincode I give an overview of the background of this concept and I conclude with a hands-on example written in Node.
Certified Blockchain Solution Architect
Blockchain is one of the future digitalisation developments which increases the transparency, the security, and the efficiency of applications implemented cross-organizationally. With the certification Iris can officially document her knowledge and competences in the following topics: Principles of the blockchain Functions and advantages of the blockchain Types of blockchain Fields of application Architecture of the Blockchain Design and development of a Blockchain Blockchain Training Alliance (https://blockchaintrainingalliance.com) Customers benefit from the professionalism to find the appropriate blockchain solution, to design it regarding the customer requirements, to support the development of the blockchain, and to hand over blockchain knowledge.
Hyperledger Fabric (HLF) / Node.js - part 3, Chaincode, Client-SDK, Binary Version Peer/Orderer
In this Meetup we use the binary edition of a chaincode devmode environment to analyse how the Node.js SDK can be applied. We build on our work of 29th of January 2021 and benefit from the binary versions of peers and orderers generated in this session to create a Node.js chaincode and to access it for test purposes.

Hyperledger Fabric (HLF) / Implementation of a chaincode with Node.js - part 2 CouchDb
In this meetup we expand the example of the meetup on 26th February 2021 with a CouchDB query. Furthermore, we learn how CouchDB as State-Database in Fabric 2.2 can be activated and how we can use this in the development phase of a chaincode.

Hyperledger Fabric (HLF) / Implementation of a chaincode with Node.js - part 1
In this meetup we look at the building process of a chaincode by means of Node.js. The following fields are examined more closely: –peer-chaincodedev mode with Docker, fabric-chaincode-api (Node.js), installation of the developed chaincode in the test-network, and the creation of a simple test script to analyse the performance.

Hyperledger Fabric (HLF) / How to Use Node.js for HLF Application Development - an Overview
This article gives an overview how Node.js can be implemented in the development of applications in a HLF project. We look at the development of smart contracts as well as the usage of Node.js to interact with the blockchain network. Furthermore, I give a short overview of the CHFD (Certified Hypberledger Fabric Developer) certification.

Hyperledger Fabric (HLF) / Chaincode Development Environment - a Comparison
In this article I compare two different approaches how the Fabric Chaincode Development Environment can be applied. For this purpose a PEER in a –peer-chaincodedev mode can be started. The advantage of this method is the avoidance of running through the whole installation process after a change of the chaincode. For testing the changes a restart of the chaincode containers is sufficient. Thus, the testing of a chaincode is simplified.
Hyperledger Fabric (HLF) / DAML - an introduction
In this meetup we are going to have Anthony Lusardi as a guest speaker. He will give us an introduction to Daml, a programming language and techstack for distributed ledgers along with a live demonstration of Daml’s unique ability to be written once and deployed anywhere including Hyperledger Fabric 2.2 and Sawtooth.
