In October, Greenland was reported to be exploring the feasibility of a web based voting platform for its nationwide elections. Among the choices being thought-about is a blockchain-based system.
That isn’t solely shocking. Electronic voting, or e-voting, has lengthy been seen as a promising use case for blockchain know-how. “It’s time for online voting,” wrote Alex Tapscott in a New York Times opinion piece in 2018. “Using blockchain technology, online voting could boost voter participation and help restore the public’s trust in the electoral process and democracy.”
It appears particularly well timed now as massive swaths of the world’s inhabitants are elevating questions on election integrity — most notably within the United States, however in different international locations as nicely, resembling Brazil.
Tim Goggin, CEO at Horizon State, for one, believes that blockchain-enabled elections signify a “significant improvement” over the way in which most elections are operated right this moment. Voting machines break down, software program fails and election irregularities typically create uncertainty and doubt among the many voting public.
With a public blockchain, by comparability, “it is much easier for voters to trace their vote,” Goggin instructed Cointelegraph, “and audit an election themselves.”
Moreover, if one thing untoward does happen within the voting course of, it’s simpler to establish it on a decentralized ledger with hundreds of nodes than on present tabulation programs “where counting is done behind closed doors,” says Goggin, whose firm arrange a public election for South Australia in 2019, the primary time blockchain know-how was used within the voting course of for that Australian state.
Still, blockchain know-how’s potential vis-a-vis public elections has been highlighted on and off for a while now. No nation has but to make use of blockchain know-how in a nationwide election.
Marta Piekarska, senior DAO strategist at ConsenSys, remembers working at Hyperledger in 2016, the place blockchain voting was mentioned as a promising use case. “Six years later, and we are still talking about this,” she instructed Cointelegraph. “We are still quite far from a situation where any kind of distributed ledger would be considered” — at the least in a nationwide election.
Just a few international locations, notably Estonia, have been experimenting with programs that permit individuals to vote on-line, she additional defined. On the opposite hand, “Netherlands abandoned the idea of doing electronic voting due to some of the concerns around security and authenticity of the votes.”
Then, there’s sparsely populated Greenland, the place the huge distances make it tough for individuals to vote in individual. A bunch of researchers from Concordium Blockchain, Aarhus University, the Alexandra Institute and the IT University will quickly be investigating “whether a blockchain-based system will be a more trustworthy e-election on the world’s largest island,” in accordance with the Concordium press launch.
Ensuring belief is important
Any voting system requires belief, and belief requires plenty of properties — any one in all which could be a problem relying on the circumstances, Kåre Kjelstrøm, chief know-how officer at Concordium, instructed Cointelegraph. For in-person voting, these embrace: whitelisting: guaranteeing solely eligible voters participate; identification: voters have to show their id when casting a vote; anonymity: votes are solid in non-public and may’t be traced again to the voter; safety: places are secured by the federal government; and immutability: solid votes can’t be altered.
“Any digital system that replaces a manual voting system needs to address at least those same issues to ensure trust and this has proven to be rather tricky to pull off,” Kjelstrøm defined. “But blockchain may prove to be part of a solution.”
A public decentralized blockchain ensures immutability by default, in any case, “in that any transaction written can never be deleted.” The system is secured by cryptography and “transactions are anonymous, but are open for inspection by anyone in the world,” mentioned Kjelstrøm, including:
“The trick is to maintain privacy and anonymity while ensuring any eligible voter can only cast their vote once. […] This is a current research topic at top institutions.”
Permissioned or public chains?
“The main problems I see for public elections as opposed to say corporate governance is that there cannot be a permissionless [blockchain] system because voter information is private and we cannot trust all third parties,” Amrita Dhillon, professor of economics within the division of political economic system at King’s College London, instructed Cointelegraph.
“The second problem is that of inputting the vote at a location of the voters choice: We cannot prevent anyone coercing voters at the point at which they submit the e-vote,” she added.

Others say permissioned chains aren’t the reply as a result of they’re run by a single entity or a gaggle of entities that exert full management of the system. “Worst case this means that a private blockchain can be tampered with by those self-same guardians and elections rigged,” mentioned Kjelstrøm. This isn’t a lot of an issue in Western international locations, “but in large parts of the world this is not true.”
On the opposite hand, if one can “weave self-sovereign identity (SSI) into the core protocol,” as Concordium, a layer-1 public blockchain, aspires to do, that “may be just the right technology to power public elections,” mentioned Kjelstrøm.
That mentioned, Goggin famous that many governments will in all probability decide to make use of non-public blockchains in step with their very own privateness/knowledge legal guidelines, and there are lots of methods to arrange permissioned blockchains. But, in the event that they don’t at the least provide the general public an auditable hint of voting information, then they aren’t more likely to increase the general public’s perception in election integrity. He calls himself “a big fan” of public and distributed blockchains.
The privateness query is particularly knotty relating to public elections. “You should not be able to tell which candidate some individual voted for, or even if they voted at all,” wrote Vitalik Buterin in a weblog titled “Blockchain voting is overrated among uninformed people but underrated among informed people.” On the opposite hand, you wish to guarantee — and if vital show — that solely eligible voters have voted, so some info like addresses and citizen standing might have to be collected. Buterin seen encryption as a strategy to get across the privateness conundrum.
Goggin suggests one thing related. Horizon State would possibly ask a shopper to “hash,” i.e., encrypt or scramble, eligible voter identities “before we are provided them, and we then hash those identities again.” This implies that neither the shopper nor Horizon State can readily decide who voted or how they voted. He added:
“Voters will be able to see their vote on the chain, but there is no way for voters to prove that it is their vote, given they can see other votes on the blockchain also.”
Dhillon, for her half, proposes a compromise the place “some parts of the process are centralized,” i.e., voters come to a sales space the place their id is checked and so they submit their vote, “but subsequent parts of the chain can be decentralized to make them more secure and tamper proof.”
In 2014, the town of Moscow’s Active Citizen e-voting platform was created to let Muscovites have a say in non-political municipal selections, and in 2017 it used the Ethereum blockchain for a collection of polls. The largest of those tapped 220,000 residents and the voting outcomes have been publicly auditable. It revealed some scaling limitations.
“The platform based on proof-of-work reached a peak of approximately 1,000 transactions per minute [16.7 transactions per second]. This meant that it would not be easy for the platform to handle the volume if a higher proportion of Moscow’s 12 million citizens participated in the voting,” in accordance with Nir Kshetri, a professor on the Bryan School of Business and Economics on the University of North Carolina at Greensboro. From this, Kshetri and others concluded that this PoW model of the Ethereum blockchain “was not sufficient to handle national elections.”
Things is perhaps totally different in 2023, nonetheless, when Ethereum 2.0 implements sharding. This may increase the chain’s velocity to as excessive as 100,000 TPS, which in flip “increases Ethereum blockchain’s attractiveness for voting,” he instructed Cointelegraph.
But blockchains in all probability nonetheless have to be safer earlier than they’re prepared for public elections, although that is manageable in Kshetri’s view. “Blockchains are likely to become more secure with increasing maturity.”
Buterin, too, mentioned in 2021 that safety was nonetheless a difficulty vis-a-vis elections. For that cause, “in the short term, any form of blockchain voting should certainly remain confined to small experiments. […] Security is at present definitely not good enough to rely on computers for everything.”
Online transactions, not like guide programs, “can occur in the blink of an eye,” added Kjelstrøm, and software-driven assaults on an e-voting system can “potentially foil or damage the system or the vote.” Therefore, “any new system would have to be introduced slowly to ensure the voting system remains intact and fully functional.” Governments would possibly start at a small scale and conduct proof-of-concepts for choose non-critical elections first, he mentioned.
Usability is important
Technology isn’t the one impediment that must be solved earlier than blockchain voting attains broad adoption. There are political and social challenges, too.
“The technology is there,” mentioned Piekarska. “We can do it right now. I mean, decentralized autonomous organizations are governed through online voting now, and they are managing trillions of dollars.” But nationwide elections are a special beast, she instructed, as a result of:
“On the government level, your problem is: how do you create a system that is usable by citizens?”
One’s constituency is just not tech-savvy members of a DAO, “but people like my mom, who is still struggling with online banking,” Piekarska added.
How lengthy will or not it’s, then, earlier than the primary nationwide election with blockchain voting? “Hopefully not decades, but surely we’re not there yet,” mentioned Kjelstrøm.
“It could be tomorrow or it could be in 50 or 60 years,” opined Piekarska, “because there are so many things that need to align.” In Europe, most individuals belief their governments and the standard of voting is just not actually a difficulty, so the push for encrypted auditable ledgers will not be so pressing. In nations with weaker governance the place elections are sometimes manipulated, conversely, why would the powers-that-be ever consent to tamper-free blockchain voting?
Greenland, which struggles with participation in its normal elections primarily due to the nice distances that its residents should journey to vote, would possibly show an exception.
“Yes, some solid governments want to do the right thing but they struggle with the accessibility of in-person voting,” Piekarska acknowledged. “That’s probably where we might see the first movers because there is a very high incentive for them to do it. But these are unique situations.”

All in all, it’s important that individuals have belief of their voting system, whether or not guide, digital or blockchain-based, and constructing belief can take time. But, as extra individuals turn out to be used to accessing public providers on-line, digital voting ought to take larger maintain in numerous elements of the world, and as soon as that occurs, blockchain voting may catch on, given its well-documented benefits, permitting people to audit their very own votes.
Large-scale blockchain-enabled nationwide elections are in all probability some years away nonetheless. Even so, Goggin has been partaking in discussions lately “about providing elections at that scale,” including:
“While it isn’t the norm yet, governments are beginning to consider the value that online blockchain voting systems can offer in efficiency, accessibility, speed, security and transparency.”
