How to setup Hyperledger Indy With Nodejs wrapper in Linux machine
FoundationHyperledger Indy is a distributed ledger software that is coming under the Linux Foundation. It is a project in the Hyperledger greenhouse. Hyperledger Indy provides tools, libraries, and reusable components for providing digital identities rooted in blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo. Indy is interoperable with other blockchains or can be used standalone powering the decentralization of identity.
So let's begin how to setup Hyperledger on your machine. The following are the prerequisites for Hyperledger Indy.
1. Git 2.27
2. Node Js 8.12.0
4. Docker 1.18
5. Docker-compose 1.22
Installation of Libindy:
sudo apt-key adv — keyserver keyserver.ubuntu.com — recv-keys 68DB5E88
sudo add-apt-repository “deb https://repo.sovrin.org/sdk/deb xenial master”
sudo apt-get update
sudo apt-get install -y libindy
- (xenial|bionic) xenial for 16.04 Ubuntu and bionic for 18.04 Ubuntu.
After you have these all prerequisites on your machine you are ready to go with Hyperledger fabric.
Step by step guide to setup Hyperledger Indy node Wrapper
Install Indy SDK repo:
git clone https://github.com/hyperledger/indy-sdk.git
Run using node js SDK:
Step 1: npm run ledger ( This command will create a docker container with preconfigured stewards node)
You can see the configurations if go to ci/indy-pool.dockerfile dockerfile and you can change them according to your requirements. I will discuss it in one of my coming articles.
Then You will see it will pull all the necessary Docker images and it will create the container for stewards node. You can see it by issuing docker ps -a command on the command line.
Step 2: npm install ( Installing all required packages )
Step 3: npm run start ( Starting the Alice use case )
