Using Blockchain for Voting

Can technology play a greater positive role in democracy and the way people make important decisions about the future of their countries? With digital voting, a new wave of challenges rolls in: from guaranteeing the anonymity of voters to the prevention of fraud, all the while ensuring the security of the voting system itself. One small vulnerability or oversight could very well change the course of a nation's history.

Voting is the free world’s Trojan horse. Valid voters are suppressed. Vote audits are suppressed. Voter registration systems can be hacked. And the worst-case scenario of all looms before us all like a monster in a horror movie: what if voting machines themselves are hacked, the “results” are faked and democracy is quietly cancelled without the general public even noticing?

We do our banking, our shopping and manage our relationships online. But our democracy remains decidedly analogue: in 2017, the simple act of casting a vote requires citizens to trudge down to a polling booth, queue up, and tick a box on a voting slip. 

Thousands of people around the country then frantically count votes overnight, with results slowly dripping in through the morning, constituency by constituency.

Wouldn’t this all be a lot easier if we could vote from home on our computers, or even on our smartphones? 

Despite the digitalisation of several important aspects of modern life, elections are still largely conducted offline, on paper. Since the turn of the century, e-voting has been considered a promising and (eventually) inevitable development, which could speed up, simplify and reduce the cost of elections, and might even lead to higher voter turnouts and the development of stronger democracies. E-voting could take many forms: using the internet or a dedicated, isolated network; requiring voters to attend a polling station or allowing unsupervised voting; using existing devices, such as mobile phones and laptops, or requiring specialist equipment.

Now we have a choice: to continue trusting central authorities to manage elections or to use blockchain technology to distribute an open voting record among citizens. Many experts agree that e-voting would require revolutionary developments in security systems. The debate is whether blockchain will represent a transformative or merely incremental development, and what its implications could be for the future of democracy.

Blockchain technology originates from the underlying architectural design of the cryptocurrency bitcoin. It is a form of distributed database where records take the form of transactions, a block is a collection of these transactions. With the use of blockchains a secure and robust system for digital voting can be devised.

Blockchain was first introduced by Satoshi Nakamoto (a pseudonym), who proposed a peer-to-peer payment system that allows cash transactions through the Internet without relying on trust or the need for a financial institution. Blockchain is secure by design, and an example of a system with a high byzantine failure tolerance. Bitcoin is considered the first application of the Blockchain concept to create a currency that could be exchanged over the Internet relying only on cryptography to secure the transactions. Blockchain is an ordered data structure that contains blocks of transactions. Each block in the chain is linked to the previous block in the chain. The first block in the chain is referred to as the foundation of the stack. Each new block created gets layered on top of the previous block to form a stack called a Blockchain.

Current Digital Voting Systems
A number of digital voting systems are currently in use in countries around the world. Estonia has had electronic voting since 2005 and in 2007 was the first country in the world to allow online voting. In the 2015 parliamentary election 30.5% of all votes were made though the nation’s i-voting system . The bases of this system is the national ID card that all Estonian citizens are given. These cards contain encrypted files that identify the owner and allows the owner to carry out a number of online and electronic activities including online banking services, digitally signing documents, access their information on government databases and i-voting. Soon after, electronic voting was adopted by Switzerland for its state-wide elections, and by Norway for its council election.

For an electronic voting system to compete with the traditional ballot system, it has to support the same criteria the traditional system supports, such as security and anonymity. An e-Voting system has to have heightened security in order make sure it is available to voters but protected against outside influences changing votes from being cast, or keep a voter’s ballot from being tampered with. Many electronic voting systems rely on Tor to hide the identity of voters. However, this technique does not provide total anonymity or integrity since many intelligence agencies around the world control different parts of the Internet which can allow them to identify or intercept votes.

Estonian I-Voting System: Estonia was the first country where citizens were able to cast their vote using only the Internet and an electronic national identification card. The ID card used in the elections was designed to run on an integrated circuit, a chip. The card is able to create signatures and is easily usable for authentication, encryption, and signatures. The voter has to download the voting application, authenticate using the electronic ID, and if the voter is eligible to vote a list of candidates will be displayed and a vote could be cast. The vote will be encrypted using the election’s public key and signed with the voter private key. As soon as the vote is cast it will be sent to a vote storage server controlled by the Estonian government. Voters could vote multiple times, and only the last vote will be considered valid. This is done to prevent vote buying.

Norwegian I-Voting System: In 2011 Norway used an electronic remote voting system for the country council elections. The system was developed by e-voting vendor Scytl, and was very similar to the Estonian electronic voting system. However, in 2014, the country has discontinued its I-Voting project due to security concerns. One of the main critics Norwegian I-Voting system faced was the fear of votes going public in case of a cyber attack.

Difficulties with Current E-Voting/I-Voting
One can argue that there are three main requirements in facilitating elections. Firstly, all votes must come from registered voters who can cast a maximum of one vote. Secondly, the final count must reflect all votes cast. Finally, the casting of the vote must be ‘receipt-free,’ so that a third-party cannot determine how a user had voted, to prevent vote buying and coercion. After all, the private ballot is of the utmost importance.
With onsite e-voting, the machines themselves pose a liability; the possibility of malware on the client side machine that monitors the user placing their vote and then later changing their vote to a different candidate. Further, the presence of trojans, viruses or other software when the vote is cast can cause nefarious interference. 

Additionally, the machine can also be the target of attacks if the servers that store the encrypted data are hacked. As each voting station across a nation will access the server to store the data, the machines are key access points and thus a vulnerability. This was the case, allegedly, with the latest US presidential elections.

On the other hand, internet voting poses difficulties with validating the user, as the system requires sending information to a server to verify the voter is who they say they are. As a result, there could be issues with the user’s computer being compromised or difficulties arising out of using public WiFi to vote. 

There is also the client issue of integrity, such as if the user’s device is compromised, allowing a keylogger, for example, to record the user’s credentials and use them to vote against the will of the original user. Verifying the user presents an issue for the privacy of the vote, since the server will record the time of voting, alongside a personal identifier, potentially usurping the protections in place to guard the freedom of voting, since governments could identify the voter and how they voted. Hackers can also manipulate the verification software into thinking a vote has been cast – or cast differently. This conflicts with the receipt-free approach.

Moreover, log-in credentials can be stolen, misused or forgotten, potentially locking someone out a vote or allowing another to vote as they wish. Additionally, the lack of a paper trail to combat the aforementioned privacy breach would make auditing the results harder. 

To quote Ronald Reagan: “Trust, but verify.” 

Is Blockchain the Solution?
An undoubtable advantage of blockchain is the inability to retroactively edit ‘blocks.’ Once a vote is in the chain, with the voter being declared as voted, it is un-editable, creating ‘an immutable and tamper-proof way,’ to store the vote. Any attempt to edit the chain would invalidate the later versions, showing that there had been tampering. This provides protection against attempts to alter the votes thus eliminating one of the avenues for voter fraud: manipulating the voting database.

Since elections are a trusted system, there is no need to protect against a centralised power, as the nature of the elections provide that there is a centralised authority giving oversight. As such, this would allow the central authority to oversee the encryption nodes which store and distribute the chain, protecting against tampering in real time. With onsite devices or internet voting, it is harder to audit such systems on the fly.

While blockchain was explicitly designed for transactions on a public ledger, without central oversight, its characteristics make it malleable to support voting systems. Designed as a solution to double-spending in e-cash situations, this can ‘also ensure there is no double voting, and its transparency and public availability make it auditable.’ Votem CEO, Pete Martin, adds that blockchain is ‘fault-tolerant, you cannot change the past, you cannot hack the present, you cannot alter the access to the system, every node with access can see the exact same results, and every vote can be irrefutably traced to its source.’ 

Furthermore, each voter has the ability to change his or her vote at any time during the process, using their unique ID that is attached to the chain.

Case Study: Blockchain Voting for Peace – Colombia
In order to give Colombian expatriates a voice in a 2016 Peace plebiscite and test the potential of Blockchain technology in electoral processes, the tech non-profit Democracy Earth Foundation set up a digital process that allowed Colombian expats, who were unable to vote through the official process, an opportunity to participate in a plebiscite on whether to approve a peace treaty. This process raised interesting questions for governments about the future use of blockchain in electoral processes, and in the public sector more broadly, and could potentially lead to new ways to ensure the integrity of the election process.
