Circulor, working with the government of Rwanda and Power Resources Group, has launched the first production ready system to trace a conflict mineral, Tantalum, from mine to manufacturer. It’s an incredible use case with massive social impact.
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 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.
I have configured amazon managed blockchain setup with Hyperledger 1.2. The network is prepared with a single member and a single peer node. Hyperledger Fabric Client setup is with Golang 1.10.3. I have installed, Instantiated, Queried and Invoked mycc chaincode example given in AWS tutorial
In ChainCode development, When to have a Multiple organization in the network, In case only a specific Organisation can call a specific function of chain code.
I'm using CouchDb in Fabric and I have the next JSON document
Throughout my career, a multitude of people have asked me <em>what does it take to become a successful developer?</em>
I have started learning hyperledger. Became familiarised with it by creating a sample app using the composer playground. My doubt is regarding the <strong><em>decentralized storage using hyperledger</em></strong>. I have read some few docs which mentions about :
I am trying to build & test the following program on a clean install of Ubuntu v18:
I am new to blockchain technologies. We have bided against the potential project on hyperledger. So I was reading the documentation of hyperledger Sawtooth. In the documentation, I found Sawtooth core and Sawtooth Sabre. From the documentation , in a layman term I can make out that Sawtooth core provides you the platform and Sawtooth Sabre is a way making smart contracts.
In Hyperledger Fabric 1.3, how can I ensure that all organizations have signed the chaincode to install ?
According to Hyperledger Fabric website, it states:
We are facing issues to deploy our network on multiple machines. We want to deploy our network on local machines and wants the communications between different peers and organizations. So it is possible to use SOLO for communications. If yes then how. and If no then why?
I'm trying so hard to find out exactly how organizations are connected with each other in Hyperledger.
I have a transaction processor function, for example.
I have two Ubuntu servers in a corporate environment. My plan is to setup a Sawtooth Validator on one machine and Sawtooth Client on the other.
I have simple question about Hyperledger Fabric. so here is my question:
I want to perform CRUD operations in Hyperledger Sawtooth.
