Blockchain For Voting: Crystal Honesty Based On Mathematics

It seems like no industry cannot be disrupted by digital ledger technology. We often hear that the transition to distributed ledgers is improving financial systems, healthcare records, supply chain management, etc. But an operating blockchain-based voting system is something that we all probably need most. And here’s why.

Even though it varies from country to country, there are problems of fraud and corruption when it comes to elections. Often, these problems occur during the calculation process after the votes are already submitted. The decentralized ledger allows the elimination of intermediaries between voters and elected candidates, ensuring a higher level of democracy and transparency, not mentioning the decreased cost for elections.

Blockchain-Based Voting System: Technical Advantages

If electronic voting is built on the blockchain, it will naturally embrace its main features, such as transparency, security, and immutability. And this is what the current processes tend to lack.

  • Security. As the ledger is not placed on one server but in different locations, which makes it a highly secure system when it comes to attacks. There is no single control over the network, and yet, it is verifiable and traceable.
  • Immutability. Every node in the network approves every transaction. Thus, the entered votes (transactions) cannot be modified. It is easy to trace back any vote and see when and where it happened. Thereby, the voter’s identity is not revealed because of the encryption.
  • Efficiency. In the traditional system, it takes much time to process the results. Conducting out elections with the distributed ledger system, on the contrary, can be super fast. The results are immediately available right after all votes are entered, regardless of their number. It is only a matter of choosing the blockchain with the best performance and capacity.

Moreover, blockchain for voting can increase the number of people taking part in it, which is a huge problem nowadays. For example, only about 56% of US citizens cast ballots for the presidential elections in 2016. Online polling with security and transparency ensured by the decentralized ledger can become a solution for those who are not able to personally come to the polling place.

Areas Of Application — From Large Companies To Entire Countries

Naturally, elections are the most straightforward and massive area of application for blockchain-based voting. Applications for voting can be used at the federal, state, and local levels. Parliaments can also take advantage of distributed ledger technology when polling for bills to become laws.

If we look at a broader picture, elections do not only consist of choosing the candidates. Votes are often based on the information we obtain about them during the promotional campaigns. The decentralized ledger can serve as a database of news that cannot be faked and help us trace the initial source of information. Or, articles can gain more trust through the upvotes or lose reputation via downvotes executed in the blockchain as well.

Not only governments can benefit from a blockchain-based e-voting system but also various companies and organizations. Companies can roll out a private digital ledger for electoral needs, power diversification, and corporate democracy nurturing. For example, it can be used by shareholders at the annual meetings. Or, an organization can integrate an internal token system where each employee is awarded tokens for high performance. The more tokens an employee has, the more electoral weight they have.

World Examples And Results of Blockchain for Voting

West Virginia has been numerously hitting the headlines for using blockchain voting app for mid-term elections. About 140 people living abroad in 29 countries have used Voatz app instead of submitting papers via mail or using a landline telephone. All they needed was an Apple or Android smartphone and an ID. Voatz has been selected for this purpose because of the prior successful running of over 30 pilots using a permissioned blockchain. The app is built on the Hyperledger framework.

Tsukuba became the first Japanese city to launch blockchain for the voting system, currently tested on social contribution projects. Users cast ballots via My Number identification and user interface. Even though some minor problems occurred, the government of Tsukuba is willing to continue developing the system in order to prevent polling data altering.

There are also examples of blockchain for online voting in the company. Santander bank has reported conducting the first-ever distributed ledger investor polling at the annual general meeting. The proxy polling digital ledger pilot has been executed in cooperation with Broadridge Financial Solutions.

Earlier, Nasdaq has also announced a successful test of a decentralized polling solution with Estonian LHV Group. Various stakeholders involved in the experiment used their Estonian digital IDs for authentication, viewed respective information about meetings, and voted through one of the four web-based user interfaces.

How To Create A Blockchain-Based E-Voting System?

We can think of a decentralized electoral system consisting of four main parts: user interface, identification system, arbitration system, and the blockchain itself. Normally, a user needs a smartphone or a laptop with an Internet connection, a browser, and a front-facing camera. They authenticate with a system by creating an account and uploading supporting documents. Once the vote is submitted, it is transferred via an arbitration system to the digital ledger where the actual polling takes place. All the votes are recorded in a distributed ledger that is available for the public but without revealing personal information for the voters.

There are different approaches to when it comes to selecting languages, tools, and frameworks for blockchain voting app development. For example, just like the above-mentioned Voatz app, the e-Vote solution developed by Luxoft is built on Hyperledger initiated by Linux Foundation and supported by IBM. Agora team has developed its digital ledger called the Bulletin Board based on Skipchain architecture. Thereby, the data is cryptographically tied to the Bitcoin blockchain.

Thereby, there is no universal guide on how to build a blockchain-based e-polling system, but it requires particular skills and experience, from the basic understanding of the distributed ledger technology to evaluating the potential load and choosing the most suitable frameworks.


Along with blockchain for medical records, decentralized voting is one of the most promising directions because it is aimed at solving real problems. Considering the areas of usage, there is a space for many apps, but only the best ones will fill the niche. And that is why it is vital to find experienced developers for these needs.

Inn4science team members provide blockchain development and consulting services based on the expertise and many years of practical experience. Apart from many outsourcing companies that are only diving into the decentralized ledger systems, we’ve been in the industry for a while and know precisely how blockchain voting works.
