Technology-Stack:

• Front-End Development: HTML,CSS,Bootstrap,Vanilla JS,Jquery
• Data-Processing and Blockchain Development: Python 3.6.5
• Back-End Development: Django-Python Framework
• Database management: DB SQLite

Voter Authentication :

• The voter authentication is carried out in two steps and it is implemented using Aadhaar API services.
• A voter has to provide his Thumb impression ID and Aadhaar ID to the system which will serve as an input to Aadhaar API.
• Aadhaar API will provide the result as a basic detail of the voter if he/her has been successfully authenticated.

Vote Casting and Blockchain REST API Development:

• Here system will create a unique voter ID for the voter.
• Again the voter will cast a vote for any one of the candidate.
• After vote casting there are six different steps are carried out for which we have designed a special REST API:
  1. Transaction Verification
  2. Proof of Work Algorithm
  3. Block creation and Serialization
  4. Block Broadcasting and validation
  5. Consensus Algorithm
  6. Byzantine Fault Tolerance

Peer to Peer (Distributed) Network Design:

• A peer to peer distributed network on which the blockchain architecture works.
• A Web Socket request API for broadcasting the all the requests into P2P network.
• Handling concurrency by using a mutex lock mechanism.

Database Management:

• A relational DB SQLite is used as a database for the project.
• Many cryptographic and encryption algorithms are used to store the data securely in the database (SHA-256, CSPRNG, salt-hashing, etc).
• Complete normalization is also achieved in different relations of the database.

Admin Section:

• This panel is only reserved for the governing body of an election.
• Every admin is assigned a unique Election Commission ID for authentication.
• Result analysis of election is carried out in this section.
