Hi to all, Currently, in my setup, I have 2 organizations with 2 peers each. Also have 2 Orderers, one per each organization, and a CA per Organization too. They have a Kafkas and Zookeepers consensus

Hakan, Fabric doesn't care if you use certificates you wrote on a cocktail napkin. You could probably, technically speaking, use the same certificate everywhere, for everything. But that does not

Hi Hakan For the 2), you have several options: a) The CA generates self-signed certificate and key b) you provide them to the CA (manually or HSM) So the CA does create the root certificate if you

Hi Jean-Gaël and Joe, This is not my understanding. 1. Fabric doesnt care about if root certificate is self-signed or not. Root certificate of an organization is encoded in the genesis block, Fabric

Hakan, Generating certificates using a Certificate Authority (and not cryptogen) is a fact of life for Hyperledger Fabric users who are interested in deploying something in production. Cryptogen is

Hi, cryptogen uses self-signed root certificates to generate all the other certificates and keys. IMHO one of the purposes of a blockchain is to bring trust between entities that do not necessarily

Hi, To my knowledge, cryptogen is the most convenient tool for now to create the initial certificates. I dont want to create the certificates manually, nor want to write some scripts for certificate

Alok, I wrote a couple of blog posts earlier this year on Hyperledger Fabric performance and

Hi Suresh, It must be the exact same folder with the exact same files when you install. But that's not for production, here's what you do: 1. In org1 where you instantiated the chaincode, run

Hi All, Initially, I have Org1 in my fabric network. after that, I added Org2 into the consortium My question is I already install and instantiated the chain code in org1 Now I stall the same

Hello There, We are conducting a POC for Oil & GAS Retail automation. In which, we are recording all digital/ cash sales onto the Fabric ledger. We monitor the stock levels in the fuel tanks through

Trevor, you can take a look at this tool. https://github.com/litong01/hfrd Thanks. Tong Li IBM Open Technology "Trevor Lee Oakley" ---11/05/2019 07:53:49 PM---I need to test a HLF app, and I am

I need to test a HLF app, and I am seeking testing tools which can test the security, code audits, efficiency etc of the systems. Are there any utilities for such testing? Thanks Trevor

PBFT has an "all to all" messagepattern, so it means that all nodes need to send to all nodes messages. While it can sustain up to a third faults,it doesn't mean you'd want to run a deployment of PBFT

this statement is so flawed, there is no such requirement in ALL public blockchains. at most you can say is this is true for private/consortium blockchains, even that is terribly flawed since even

Dear Artem, i have found this https://jira.hyperledger.org/browse/FAB-15703 Seems that migration from solo to kafka is impossible but solo to raft it's possible in

No, this is not that I've said. I told that there is no way to migrate from Solo to Kafka ordering service and there no one should use Solo for production. Changing orderer type from Solo to Kafka

Dear Artem Barger, You say me that if i change orderer i lost all the transaction in my ledger? There is no way to mantain the transactions? Thanks for your

Hey, Thanks to all for the help. I am extremely grateful to everyone. Abhijeet Bhowmik
