hyperledger

I'm trying to deploy hyperledger fabric on a raspberry pi, but it doesn't work. I'm searching for some tutorial but i didn't found it, there are someone that just did it? Artem Barger Last time I've tried to run Hyperledger Fabric on RPi I've prepared following instructions: Install latest RASPBIAN on SD card, you can download image from:
 https://www.raspberrypi.org/downloads/raspbian/ Update and upgrade latest by running:
 sudo apt-get update && sudo apt-get upgrade -y Install required dependencies:
 sudo apt-get install git curl gcc libc6-dev libltdl3-dev python-setuptools -y Upgrade python

i am using Windows 10 (64-bit) and i seem to have all the prerequisites installed. However, while running the command curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/examples/e2e_cli/bootstrap.sh | bash on Git-Bash, i will get the following error: $ curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/examples/e2e_cli/bootstrap.sh | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 1205 0 1205 0 0 976 0 --:--:-- 0:00:01 --:--:-- 988 gzip: stdin: not in gzip format tar: Child returned status 1 tar:

What are the functions of the Fabric CA Server and Fabric CA Client? What are the Roles of the Fabric CA Server and Fabric CA Client? Thanks arnabkaycee Fabric CA provides features such as: Registration of identities with roles like peer, user or application, or connects to an existing LDAP as the user registry to fetch identities of the mentioned roles. Issuance of Enrollment Certificates (ECerts) for signing and identifying Issuance of Transaction Certificates (TCerts), providing both anonymity and unlinkability when transacting on a Hyperledger Fabric blockchain (not yet available in v1.0)

Can you explain some mechanisms of privacy in Hyperledger Fabric v1.0 - those already implemented and those planned to be implemented in the future? I understand channels are like seperate blockchains. I also went through the document on https://jira.hyperledger.org/browse/FAB-1151 , where I have found two more mechanisms: one is private data, and other is encryption. Can you explain what would be the beast approach to use in the following scenario. Each car needs car insurance. Let's say the owner of the car wants to change his insurance company. He signs the contract with new insurance

I am trying to understand the "Query" transaction flow in Hyperledger Fabric. I understand the "write" flow in Fabric as it is well documented. However, things are not so clear when a read/query transaction is involved. This is what I have understood so far: A client using an SDK prepares a transaction proposal for querying a chaincode. The proposal is transmitted via a committing peer to the Endorsing peers which validate as well as simulate the transaction in their end. Assuming everything is successful, the endorsing peers return their endorsements for the proposal. Each endorsement
