The 2020 United States presidential election was met with an increase in mail-in ballots as a result of COVID-19 considerations. But whereas many Individuals stayed away from polling stations this 12 months, postal delays, rejected ballots, and different challenges emerged.

Unsurprisingly, higher methods for casting votes throughout main elections rapidly grew to become a sizzling matter of dialogue. This has additionally led some within the crypto group advocating with renewed vigor for a blockchain-based voting system for use sooner or later presidential elections.

Whereas the guarantees of blockchain embody belief, transparency and immutability, a bunch of researchers on the Massachusetts Institute of Expertise’s Pc Science and Synthetic Intelligence Laboratory identified safety flaws related to blockchain voting techniques. The researchers revealed a report on Nov. 6 explaining that on-line voting is fatally flawed since such techniques are weak to large-scale cyber assaults. The report particularly discusses blockchain-based voting techniques like Voatz, which has been utilized in U.S. municipal elections, but reportedly suffers from knowledge safety points.

Safety apart, blockchain voting techniques could also be viable

Regardless of safety considerations, some nonetheless imagine that blockchain-based voting techniques might be leveraged in main elections shifting ahead. Maxim Rukinov, head of the Distributed Ledger Applied sciences Middle of St. Petersburg State College, informed Cointelegraph that blockchain permits for a system of truthful elections to happen inside a trusted setting between members who typically don’t belief one another: “With blockchain you may make voting accessible and enhance the transparency of any election. In an ideal state of affairs, the outcomes of such a vote can’t be faked.”

Rukinov shared that he has been working with a workforce of researchers to develop a web based voting system particularly designed for enterprise use. Often called “CryptoVeche,” Rukinov defined that this explicit system shops voting ends in a blockchain, which is a kind of distributed ledger. As such, the system is extremely safe towards exterior and inner hacks.

Alex Tapscott, co-founder of the Blockchain Analysis Institute and a ebook creator, defined this intimately for a New York Instances article revealed in 2018, even earlier than the COVID-19 pandemic introduced new challenges to mild. Tapscott identified that in elections, belief is concentrated inside authorities companies, that are extraordinarily weak to hacks, fraud, and human errors. To place this into perspective, a study launched final 12 months reveals that native and federal authorities entities have fallen sufferer to 443 knowledge breaches since 2014, however these largely included misplaced {hardware}, mailing errors, and paper breaches.

Tapscott famous {that a} blockchain system depends on distributed community computer systems to confirm transactions. As soon as verified, outcomes are recorded in blocks which can be linked cryptographically to the previous block. A safe ledger is then fashioned, which is clear to all community members, but stays immutable and tamper proof. This characteristic can be necessary for making certain that people solely forged a single vote, as blockchain-based techniques are supposed to forestall double-spending. 

Don Tapscott, well-known creator and co-founder of the Blockchain Analysis Institute additional informed Cointelegraph that votes can’t be despatched on-line as we speak as a result of internet-based techniques don’t work nicely for such functions:

“If we transmit info like a vote on the Web we’re really sending a duplicate of that file; the unique stays in our possession. That is acceptable for sharing info however unacceptable for transactions with belongings, like cash, securities, songs or recording votes in elections.”

As such, Tapscott famous that inside a blockchain-based system, public belief within the voting course of is achieved by way of cryptography, code, and collaboration amongst residents, authorities companies, and different stakeholders.

Technical challenges have to be overcome

After all, there isn’t any denying that technical challenges associated to blockchain-based voting techniques stay. Along with the safety considerations talked about by MIT researchers of their current report, Rukinov acknowledged that creating a web based voting system is difficult.

Rukinov additional defined that with blockchain techniques the accuracy of transactions, on this case, voter registration is verified by a consensus mechanism between totally different members of the community. Nevertheless, in relation to voting techniques unbiased observers should even be one of many events concerned with the consensus, that means they must maintain a number of validation nodes.

In keeping with Rukinov, typically the variety of nodes owned by the community organizer are larger than the variety of unbiased nodes. So within the case of a blockchain-based voting system, an assault could happen when those that management greater than half of the sources have the power to alter knowledge at random. Rukinov identified that this downside shouldn’t be the case for every type of consensus mechanisms.

Lior Lamash, Founder and CEO of GK8, a cybersecurity firm, additionally informed Cointelegraph that whereas the immutable nature of blockchain makes it an efficient platform to make sure the integrity of the voting course of, a number of vulnerabilities stay. Particularly talking, Lamash famous that voter identification is problematic when utilizing blockchain-based voting techniques:

“The safety facet of blockchain-based voting is hard. On one hand, the blockchain itself is totally secured from even state-level hackers, because it employs a whole lot of hundreds of nodes on a number of servers throughout the globe. The problem could be in securing the ‘endpoints’ of this community – particular person ballots and voting stations.”

Furthermore, Lamash famous that whereas every poll shops a person’s non-public keys, a hacker may acquire that info and manipulate all the election course of: “This challenge is kind of much like the problem that banks and different monetary establishments face when providing blockchain-based companies.”

Plain potential

Though challenges stay with blockchain-based voting techniques, it’s clear that blockchain has enormous potential to be used in future elections. Dylan Dewdney, chief govt officer of Kylin, a cross-chain platform designed for Polkadot-based knowledge financial system, informed Cointelegraph that the trusted end result of an election should even be considered. He additional decided that blockchain being utilized for knowledge validation is extremely helpful on this case.

In keeping with Dewdney, a decentralized infrastructure may assist enhance the trusted end result of an electoral course of. Dewdney defined that Kylin has created an information validation course of utilizing an oracle node, which serves as an info feed. An arbitration node is then used to guage if that knowledge is legitimate or not. Dewdney stated:

“Anybody working an arbitration node would have a wonderful incentive to problem inaccurate info as they might be rewarded in a local token to take action. Equally, offering correct, validated (challengeable) info as a premium knowledge feeder to customers like information organizations, is extremely beneficial as a premium knowledge feed in an information market.”

Though Kylin is an answer that may simply be utilized within the decentralized finance area, the identical idea can be utilized for voting techniques. “Decentralized validation of native electoral outcomes may present a really highly effective instrument towards a few of the issues we’re at the moment seeing.” He additional added: “This might simply function because the linked consensus of the validated API feeds of actually hundreds of native election outcomes reported to web sites inside a Dapp builders premium knowledge sourcing.”

Rukinov believes that the perfect blockchain-based voting system should cater to voter eligibility, verifiability, and immutability. He talked about that these options may be achieved sooner or later by way of cryptographic protocols together with digital signatures, zero-knowledge proofs, and homomorphic encryption: “To be able to obtain extra advantages, it’s crucial so as to add the opportunity of cancelling the registration; observers having the ability to detect the information of falsification; and the permanence of the register change historical past.”
