In October, Greenland was reported to be exploring the feasibility of a web based voting platform for its nationwide elections. Among the many choices being thought-about is a blockchain-based system.
That isn’t fully stunning. Digital voting, or e-voting, has lengthy been considered as a promising use case for blockchain know-how. “It’s time for on-line voting,” wrote Alex Tapscott in a New York Instances opinion piece in 2018. “Utilizing blockchain know-how, on-line voting may enhance voter participation and assist restore the general public’s belief within the electoral course of and democracy.”
It appears particularly well timed now as giant swaths of the world’s inhabitants are elevating questions on election integrity — most notably in the USA, however in different international locations as nicely, akin to Brazil.
Tim Goggin, CEO at Horizon State, for one, believes that blockchain-enabled elections signify a “vital enchancment” over the best way most elections are operated at this time. 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’s a lot simpler for voters to hint their vote,” Goggin informed Cointelegraph, “and audit an election themselves.”
Furthermore, 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 “the place counting is finished behind closed doorways,” 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.
Nonetheless, 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, recollects working at Hyperledger in 2016, the place blockchain voting was mentioned as a promising use case. “Six years later, and we’re nonetheless speaking about this,” she informed Cointelegraph. “We’re nonetheless fairly removed from a state of affairs the place any type of distributed ledger could be thought-about” — no less than in a nationwide election.
Just a few international locations, notably Estonia, have been experimenting with programs that permit folks to vote on-line, she additional defined. Alternatively, “Netherlands deserted the thought of doing digital voting because of a few of the considerations round safety and authenticity of the votes.”
Then, there’s sparsely populated Greenland, the place the huge distances make it troublesome for folks to vote in individual. A bunch of researchers from Concordium Blockchain, Aarhus College, the Alexandra Institute and the IT College will quickly be investigating “whether or not a blockchain-based system can be a extra reliable e-election on the world’s largest island,” according to the Concordium press launch.
Guaranteeing belief is essential
Any voting system requires belief, and belief requires a variety of properties — any one among which generally is a problem relying on the circumstances, Kåre Kjelstrøm, chief know-how officer at Concordium, informed Cointelegraph. For in-person voting, these embrace: whitelisting: making certain solely eligible voters participate; identification: voters have to show their identification when casting a vote; anonymity: votes are forged in non-public and may’t be traced again to the voter; safety: areas are secured by the federal government; and immutability: forged votes can’t be altered.
“Any digital system that replaces a guide voting system wants to handle no less than those self same points to make sure belief and this has confirmed to be slightly difficult to tug off,” Kjelstrøm defined. “However blockchain could show to be a part of an answer.”
A public decentralized blockchain ensures immutability by default, in any case, “in that any transaction written can by no means be deleted.” The system is secured by cryptography and “transactions are nameless, however are open for inspection by anybody on the planet,” stated Kjelstrøm, including:
“The trick is to keep up privateness and anonymity whereas making certain any eligible voter can solely forged their vote as soon as. […] This can be a present analysis matter at high establishments.”
Permissioned or public chains?
“The principle issues I see for public elections versus say company governance is that there can’t be a permissionless [blockchain] system as a result of voter data is non-public and we can’t belief all third events,” Amrita Dhillon, professor of economics within the division of political economic system at King’s School London, informed Cointelegraph.
“The second downside is that of inputting the vote at a location of the voters alternative: We can’t forestall anybody coercing voters on the level 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 bunch of entities that exert full management of the system. “Worst case because of this a non-public blockchain may be tampered with by these self-same guardians and elections rigged,” stated Kjelstrøm. This isn’t a lot of an issue in Western international locations, “however in giant elements of the world this isn’t true.”
Alternatively, if one can “weave self-sovereign identification (SSI) into the core protocol,” as Concordium, a layer-1 public blockchain, aspires to do, that “could also be simply the precise know-how to energy public elections,” stated Kjelstrøm.
That stated, Goggin famous that many governments will most likely choose to make use of non-public blockchains in keeping with their very own privateness/knowledge legal guidelines, and there are various methods to arrange permissioned blockchains. However, in the event that they don’t no less than supply the general public an auditable hint of voting information, then they aren’t more likely to enhance the general public’s perception in election integrity. He calls himself “an enormous fan” of public and distributed blockchains.
The privateness query is particularly knotty with regards to public elections. “You shouldn’t be in a position to inform which candidate some particular person voted for, or even when they voted in any respect,” wrote Vitalik Buterin in a weblog titled “Blockchain voting is overrated amongst uninformed folks however underrated amongst knowledgeable folks.” Alternatively, you need to guarantee — and if needed show — that solely eligible voters have voted, so some data like addresses and citizen standing could have to be collected. Buterin considered encryption as a approach to get across the privateness conundrum.
Goggin suggests one thing comparable. Horizon State would possibly ask a shopper to “hash,” i.e., encrypt or scramble, eligible voter identities “earlier than we’re supplied them, and we then hash these identities once more.” Which means neither the shopper nor Horizon State can readily decide who voted or how they voted. He added:
“Voters will be capable to see their vote on the chain, however there isn’t a means for voters to show that it’s their vote, given they’ll see different votes on the blockchain additionally.”
Dhillon, for her half, proposes a compromise the place “some elements of the method are centralized,” i.e., voters come to a sales space the place their identification is checked and so they submit their vote, “however subsequent elements of the chain may be decentralized to make them safer and tamper proof.”
Technical limitations?
In 2014, the town of Moscow’s Lively Citizen e-voting platform was created to let Muscovites have a say in non-political municipal choices, and in 2017 it used the Ethereum blockchain for a collection of polls. The most important of those tapped 220,000 residents and the voting outcomes had been publicly auditable. It revealed some scaling limitations.
“The platform based mostly on proof-of-work reached a peak of roughly 1,000 transactions per minute [16.7 transactions per second]. This meant that it could not be straightforward for the platform to deal with the quantity if the next proportion of Moscow’s 12 million residents participated within the voting,” based on Nir Kshetri, a professor on the Bryan College of Enterprise and Economics on the College of North Carolina at Greensboro. From this, Kshetri and others concluded that this PoW model of the Ethereum blockchain “was not ample to deal with nationwide elections.”
Issues is likely to be totally different in 2023, nevertheless, when Ethereum 2.0 implements sharding. This might enhance the chain’s pace to as excessive as 100,000 TPS, which in flip “will increase Ethereum blockchain’s attractiveness for voting,” he informed Cointelegraph.
However blockchains most likely nonetheless have to be safer earlier than they’re prepared for public elections, although that is manageable in Kshetri’s view. “Blockchains are more likely to develop into safer with rising maturity.”
Buterin, too, stated in 2021 that safety was nonetheless a problem vis-a-vis elections. For that cause, “within the brief time period, any type of blockchain voting ought to definitely stay confined to small experiments. […] Safety is at current positively not adequate to depend on computer systems for all the pieces.”
On-line transactions, not like guide programs, “can happen within the blink of a watch,” added Kjelstrøm, and software-driven assaults on an e-voting system can “probably foil or injury the system or the vote.” Subsequently, “any new system must be launched slowly to make sure the voting system stays intact and absolutely purposeful.” Governments would possibly start at a small scale and conduct proof-of-concepts for choose non-critical elections first, he stated.
Usability is essential
Know-how isn’t the one impediment that must be solved earlier than blockchain voting attains broad adoption. There are political and social challenges, too.
“The know-how is there,” stated Piekarska. “We will do it proper now. I imply, decentralized autonomous organizations are ruled by on-line voting now, and they’re managing trillions of {dollars}.” However nationwide elections are a distinct beast, she recommended, as a result of:
“On the federal government stage, your downside is: how do you create a system that’s usable by residents?”
One’s constituency shouldn’t be tech-savvy members of a DAO, “however folks like my mother, who continues to be fighting on-line banking,” Piekarska added.
How lengthy will it’s, then, earlier than the primary nationwide election with blockchain voting? “Hopefully not many years, however absolutely we’re not there but,” stated Kjelstrøm.
“It could possibly be tomorrow or it could possibly be in 50 or 60 years,” opined Piekarska, “as a result of there are such a lot of issues that have to align.” In Europe, most individuals belief their governments and the standard of voting shouldn’t be actually a problem, so the push for encrypted auditable ledgers might 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.
“Sure, some stable governments need to do the precise factor however they battle with the accessibility of in-person voting,” Piekarska acknowledged. “That’s most likely the place we would see the primary movers as a result of there’s a very excessive incentive for them to do it. However these are distinctive conditions.”

All in all, it’s essential that individuals have belief of their voting system, whether or not guide, digital or blockchain-based, and constructing belief can take time. However, as extra folks develop into used to accessing public providers on-line, digital voting ought to take higher 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.
Massive-scale blockchain-enabled nationwide elections are most likely some years away nonetheless. Even so, Goggin has been participating in discussions lately “about offering elections at that scale,” including:
“Whereas it isn’t the norm but, governments are starting to think about the worth that on-line blockchain voting programs can supply in effectivity, accessibility, pace, safety and transparency.”
