Good Afternoon, I am trying to run this project on my MacBook air. I have followed the steps mentioned by you. But, I am still facing an issue.

While running npm start on the terminal i am getting the following error,

@adityaverma998

Error: Cannot find module 'fabric-network'

is an npm install issue.

run

npm install from within the server directory. Let me know if that solves it.

1) could you try using node v 8.9? Looks like u are using node -v 12.16.2 from your logs

you can use these commands to install node 8.9 and use it


  brew install nvm
  nvm install 8.9.0
  nvm use 8.9.0
horeaporutiu commented 4 years ago

then run npm install again and see if it works

Sir, Thank You so much for your corrective comments. It helped!

would you mind me asking you a few educational questions? Q1. Which Consensus Algorithm are you using? Q2. How could I change the front-end of the app, like names of the presidential candidates, and the 'V' logo on the home?

@adityaverma998

HLF uses endorsement for consensus - read more about it here https://hyperledger-fabric.readthedocs.io/en/release-2.0/endorsement-policies.html

Since this is a very simple use case - just using solo for endorsement. For me a more production-like scenario - you could have something like each presidential party owning a peer node (5 in total), and then for each vote to be counted, you may need an approval from at least 3/5 nodes (Raft consensus)

2) u can change the front end from for candidates in this file https://github.com/IBM/evote/blob/master/web-app/client/src/components/CastBallot.vue - and the other vue files in the components directory for the other parts of the front end app

horeaporutiu commented 4 years ago

for more in-depth understanding of the front end portion - you may need to look into vue.js documentation

Can't we use some form of Parallel BFT consensus algorithm to improve your application? What do you think?

horeaporutiu commented 4 years ago

There are currently no supported BFT consensus algos for Hyperledger Fabric.

If you can implement one, and make it work with this application, that would be awesome. I know Hyperledger Fabric is in the works to create a BFT consensus algo.

horeaporutiu commented 4 years ago

but to answer ur question - yes, BFT consensus algo would improve this app. and any sort of distributing network app for that matter

Loved the way you are working, sir! To give a brief introduction about myself, the following is my signature, ADITYA VERMA M.TECH (IT) SECOND YEAR STUDENT & TEACHING ASSISTANT INDIAN INSTITUTE OF INFORMATION TECHNOLOGY, ALLAHABAD (INSTITUTE OF NATIONAL IMPORTANCE) EMAIL: aditya.verma998@gmail.com, mit2018064@iiiita.ac.in To be really honest with you, I am actually working for my M.Tech Thesis work, and after analysis of various facets in Blockchain, I found out that no one has ever implemented any e-voting application using Parallel BFT or Mir-BFT(new research algorithm). Such algorithms work really great in terms of high throughput, great node scalability, and less network latency. I would love to hear from you, sir, if you could guide me to implement my concept, as you are really great at it and I am a newbie at implementing, but I am good in research. Looking to hear from you, Warm Regards Aditya

Sure - you can email me.

Closing this issue now as I see it is resolved!
