Finally, Fix my Bike with Hyperledger Fabric (Deploy Daml application on a Fabric Network)

Introduction We continue our demonstration of Daml working with various types of ledger. In the previous several articles, we have walked through the code and tested it with Daml Studio (link), and then the same code on Daml Sandbox and Navigator (link). The latest one is the same code persistent in…

Add an Organization to a Decentralized Fabric Network with No System Channel (Fabric v2.3)

Introduction In my previous article we have seen how to bring up a decentralized fabric network with no system channel. With decentralization, there is no separate orderer organization and orderers are contributed by each participating organization. Each organization now does not need to use an orderer from a third party. …
