Blockchain is a digital ledger in its most basic form.
The technology pulls its power from peers—or nodes—on its network to verify, process, and record all transactions across the system.
This ledger is never saved; instead, it simultaneously resides on a “chain” supported by millions of nodes.
Blockchain’s transaction database is incorruptible, and each record is easily verified, thanks to encryption and decentralization. Because the network does not exist in a single location, it cannot be taken down or affected by a single entity.
As previously said, blockchain can help in the formation of a modern voting system. Using the blockchain in this way would make tampering with votes nearly tricky.
The blockchain protocol will also ensure electoral transparency by lowering the number of people required to run an election and giving officials near-instant results.
There will be no need for recounts, and there would be no real risk that the election would be canceled by fraud.
The many issues uncovered in these early attempts at online voting can be solved with blockchain. Any hacker with access to the terminal will not be able to affect other systems, and a blockchain-based voting program does not worry about the security of its Internet connection.
Voters can cast their ballots without disclosing their identity or political preferences to the general public.
Officials may tally votes with complete confidence, knowing that each ID corresponds to a single voice, that no fakes can be made, and that tampering is impossible.
