Overview

BEAS

Blockchain Enabled Asynchronous and Secure Federated Machine Learning

Default Network Configuration:

The default application uses the HyperLedger Test network which bootstraps the following instances:

  1. 1 Orderer
  2. 1 Certifying Authority
  3. 2 org (org0 and org1) maintaining 2 peer (peer0 and peer 1)
  4. 1 CouchDB
  5. 1 CLI

Usage Instructions:

Prerequisites:

  1. HyperLedger Fabric v2.2.x LTS
  2. Download this repository, and merge BEAS/fabric-samples with the HyperLedger fabric-samples directory.

Network Setup:

$  cd fabric-samples/BEAS
$  ./teardownBEAS.sh
$  ./startBEAS.sh

If ./sh files have permission error (mac OS):

$  chmod u+r+x ./file_name.sh

Running the Application:

Initialise New Channel

  1. Change working directory:
$  cd fabric-samples/BEAS/javascript/storageServer
  1. Install Application Dependancies:
$  npm install
  1. Run Application
$  node server.js
