Poll-Digital

Developed by: Neil Hommes, Chris Lee, Tyler Nguyen

Why Use Poll-Digital?

Votes can be cast virtually

Tamper-proof way of counting votes

Better ballot security

Lower cost

Block

Each block has the following properties

hash

• Sha256 encoded hash of "previousHash + data + timeStamp + nonce"

  previousHash

• Hash of the previous block

data

• SHA256 Encrypted SSN of a voter

timeStamp

• current epoch time of day

nonce

• random string used to ensure block uniqueness

BlockChain

• ArrayList of blocks

isChainValid

• > Checks every hash of every block and makes sure it corresponds to the block's SHA256(previousHash + data + timestamp + nonce)
• > Ensures that no blocks are tampered before votes are counted

Next Steps

• Implement a way to validate ssn, improve gui, and make the project more dynamic.
