DAML on Hyperledger Fabric

June 23, 2020July 17, 2020Blockchain, DAMLBlockchain, daml, hyperledger, hyperledger-fabric, smart contract

Reading Time: 6 minutes In our last blog, DAML on Hyperledger Sawtooth, we deployed our DAML application on a single node Hyperledger Sawtooth ecosystem, a blockchain platform which is part of the Hyperledger project by the Linux Foundation. We also learned about Sextant for DAML which is a blockchain management platform and combines DAML with the enterprise-grade Hyperledger Sawtooth. In this blog, we will continue moving forward in our Continue Reading

June 10, 2020July 17, 2020Blockchain, DAMLBlockchain, daml, hyperledger, sawtooth

Reading Time: 5 minutes In our last blog, Deploying DAML based Smart Contracts on project:DABL, we deployed our daml application on project:DABL, a blockchain platform by digital asset. We also discussed how DAML provides support on multiple blockchain platforms like hyperledger sawtooth, fabric, Corda etc. In this blog we will take a step further in our DAML journey and deploy our application on another blockchain platform which is Hyperledger Continue Reading

Hyperledger Fabric Certificate Authority(CA) Client

January 4, 2018August 8, 2018ScalaBlockchain, hyperledger

Reading Time: 3 minutes In the previous blog, we discussed about Fabric Certificate Authority(CA) Architecture, Initializing Fabric Certificate Authority Server and Configuring the database. Now, we will discuss how to use fabric-ca-client command. We can interact with Fabric-CA Server via Fabric-CA Client and there can be multiple Fabric-CA Intermediate Servers. Each Intermediate Fabric-CA server can be configured Fabric-CA server cluster. So, to start Fabric-CA-Client we need to start the Fabric-CA-Server first. Continue Reading

Hyperledger Fabric Certificate Authority(CA)

December 10, 2017August 8, 2018ScalaBlockchain, Fabric-CA, hyperledger, hyperledger-fabric, scala

Reading Time: 3 minutes Every operation in Hyperledger must be signed cryptographically with certificates. You can generate certificates yourself using OpenSSL or by using third party. Before moving further into details of CA lets first explore Hyperledger Fabric a little. 😉 Hyperledger Fabric Hyperledger Fabric founded in 2015 which is an umbrella for open source projects some of which are Blockchain Distributed Ledger Frameworks such as Fabric, Sawtooth and Continue Reading

Starting with Blockchain Chaincode using Golang

June 20, 2017August 13, 2018ScalaBlockchain, chaincode, contract, fabric, Golang, hyperledger, smart

Reading Time: 2 minutes Chaincode, or a smart contract is a fragment of code written in supported languages like Java or Go that is deployed onto a network of HyperLedger Fabric peer nodes. In this blog, we will learn how to develop Chaincode using Golang for a blockchain network based on Hyperledger Fabric v0.6. Chaincodes run network transactions which are validated and then appended to the shared ledger. In simple Continue Reading
