votarino is e-vote platform based on blockchain technology. I implemented ths project part of my end of year project at INSAT - 2019. It was the first time I worked with hyperledger Fabric.
- A voter must only vote once.
- A vote is immutable.
- A voter can become a candidate (by provides candidature information).
- A candidate can deactivate his candidature.
- Candidature phase do not overlap with voting phase.
To create the proof of concept for 'votarino' platform, I had to use truffle, ganache, solidity and web3(metamask) to implement the fundamentals features
After creating the PoC, My supervisor suggested that we target the security concerns, we had to answer the questions:
- Does the app provide security to the user ?
- Does a public blockchain network matches the nature of 'election' (being private, anonymous, etc ...) ?
- Does the app take into consideration the influence factor (someone forcing a choice on a voter) ? (to be honest, this is a hard question to answer)
After another session of auto learning, we opted to use the Hyperledger Fabric (it supports private networks), which is a part of the Hypeledger project initiated by the Linux Foundation, and has received contributions from IBM, Intel and SAP Ariba.
We added some functional requirement for our platform:
- Each election admin can create multiple elections
- Each election will have a list of members (default voters)
- Each election must be approved by a super admin
- Election results are only accessible after the voting phase
Using Hyperledger Farbic well detailed documentation, we developed our e-vote platform, titled 'votarino'.
There is a lot more to be done with this project, some ideas are:
- Implement different format of vote, like multiple choices, delegating vote, mutable vote, etc
- Emphasis more on security and utilize identity mixer to provide a pure anonymity for the voter
- Transform the platform into a SaaS product
