Blockchain for Voting and Elections

With the election upon us, the news is by and by
humming about election tampering. Any election
result stands essentially important in forming
the eventual fate of nation's organization as
well as characterizing the fate of the political
scene of a nation for a long time to come.
Therefore elections must be straightforward and
should give deterministic outcomes. Claims of
fraud or extortion and outside impact will keep
on rising, even in advanced democracies if they
do not leverage technology to dispose of election
tampering or altering. Every nation requires a
platform that guarantees legitimate voter
registration and recognizable proof. They should
also encompass an electoral platform that
streamlines the process of checking cast a
ballot. In short, all while giving transparency
and straightforwardness to the election
  • Introduction to technology
  • Today, the vast majority of our lives are led
    over the web or internet innovations. We do our
    major banking and finance via the portable
    application, sending cash to individuals by means
    of payment portals, we pay our bills, enlist our
    vehicles on the web and associate with loved ones
    on the web and more. We hardly see any industry
    that backs from using the technology to leverage
    their service or industry function.
  • But so far we havent thought of casting a ballot
    on the web. Is it conceivable to go for online
    solutions or Internet-based technologies like
    blockchain voting system to cast a ballot and
    guarantee the honesty of our future decisions?
  • Lets take a look.
  • Even after the advent of electronic voting
    machines(EVM) and other internet innovations, a
    major percentage of the nation remain clung to
    the traditional practice of voting.

Major public opts for the ballot paper voting,
which is considered as the most secure,
transparent and trustful mode of voting practice.
This practice has been implemented long before
the inventions of the technology and remains the
most advocated means of voting for both developed
and developing nations Later came the
introduction of electronic voting mechanism
bringing a stop to the practice of ballot paper
voting. Initially, EVM claimed to be tamper proof
and trustworthy, but soon the news spread on
varied discrepancies and fraudulent activities
happening in EVM machines. The situation even
dropped to the point that a voter himself cannot
assure that his/her vote goes for the right
person. The misleads and frauds manipulated the
right of individual voting. Taking this into
consideration, many countries like USA, Germany,
Netherlands, Japan still prefer ballot paper
mechanism for their national election. It is not
like they are incapable or inefficient in
deploying the finest technologies to their voting
practices, but the question of integrity holds
them back from leveraging the initialized
electoral processes. They are well aware of the
degree of fault and misleads happening in these
Is Blockchain for the voting system- the
appropriate solution? Yes. Blockchain voting
system utilizes the deployment of smart
contracts, which permits ticket confirmation and
vote counts to be performed in a decentralized
way and checked by system members. Under the
blockchain voting system, the hackers would need
to break into a whole system of PCs and access
the information, which rarely happens. Today
there are few open source blockchain voting
platforms that are on rising. The advantages of
an open source blockchain voting system are that
it is open and does not have restrictive
calculations, enabling residents and offices to
review usefulness and enhance security. Numerous
new companies are concentrating on open source
web-based voting frameworks. There are blockchain
platforms for voting that utilizes webcam and
government provided ID to enable voters to
remotely and safely sign in to cast a vote. After
they've chosen their applicants, they can utilize
their novel voter ID to open the virtual voting
station and confirm their vote is available and
is going right. Other Blockchain voting system
application includes implementation of tokens as
QR codes to keep a similar poll from being
scanned twice. These tokens additionally fill in
as a way to open a "vote unit" that is exchanged
to the blockchain, enabling votes to be recorded
and counted progressively.
In short, Blockchain for voting and election is a
case study of digitize voting system and it is
entirely different that there exists no central
authority who can tamper or manipulate the
system. The central authority within the
blockchain voting system is the smart contract,
which is a piece of code that cannot be altered
at any cost after their deployment. How the
blockchain for voting system works? Blockchain
voting mechanism work on a smart contract which
is capable of handling millions of transaction at
a time. Implementing the voting system is not
always been an easy task in the blockchain.
Still, it's possible to implement and keep
supreme the authenticity of the voter and
determine the eligibility of the voter to cast
their ballot. The user would receive a key or a
token. This token will help the voter to exactly
cast his/her vote for a single time. That means
no multiple voting is allowed under blockchain
voting practice. We can surely say that
blockchain technology stops double
spending.Blockchain allows secure management of
public ledger.
Blockchain act as immutable database and every
data stored is managed by a network of nodes
which has exactly the same copy of data. Node is
simply a computer or a server which is connected
to a network. When a node is connected, it will
automatically import the copy of data from
blockchain. Another thing is that it
decentralizes no central authority to track or
maintain the voting system. Voting can be tracked
by anyone without breaching the security and
authenticity of the voting system. Smart
contract for voting system The smart contract
is the main piece of code that runs the system
with no need for any intermediaries. An example
smart contract in Ethereum blockchain for the
voting system.

Benefits of using Blockchain in voting The
advantages of blockchain in voting are large as
it brings in great transparency and integrity in
the voting process. As the blockchain technology
exists as a tamper-proof model, under blockchain
in voting, no individual shall be prone to
manipulate the election data. The system remains
trustful throughout the election process. Also,
blockchain in voting makes it possible for a
voter to clarify his vote that it goes to the
right candidate he intended to, which is a major
threat in the current electronic voting machine.
