Trinity’s ZKBallot makes e-voting safe with blockchain tech

The platform decouples a voter’s identification from their vote utilizing ZCash cryptocurrency and the Zero-Data Proof methodology.

Trinity Faculty Dublin’s (TCD) Utilized Cryptography Analysis Lab has developed an digital voting system that utilises blockchain expertise to protect privateness whereas permitting for a clear audit.

The ZKBallot platform decouples a voter’s identification from their vote utilizing ZCash, a privateness preserving cryptocurrency and Zero-Data Proof (ZKP), a sophisticated cryptography mechanism which lets you show one thing without having to share any pointless data.

Elaborating on ZKPs, Hitesh Tewari, an assistant professor at TCD and the principal investigator on the analysis lab, says that the mechanism, in essence, can be utilized to show {that a} voter is allowed to vote with out revealing their identification.

Voting utilizing the ZKBallot works equally to different current e-voting programs the place voters obtain an electronic mail hyperlink, which they will use to pick their most popular candidate to be able to solid the vote.

Nevertheless, this technique preserves the voters’ identities by changing their votes into ZCash tokens issued to a shielded handle, that means the system doesn’t know the place the issued tokens went. This manner, the vote can’t be traced again to the one that solid it.

“[We] break the hyperlink between the voter and the token itself… and we don’t enable anyone, even the system doesn’t know who received which token and who solid which [token] the place,” Tewari explains.

Via the platform, voters can choose their most popular candidate by giving them their issued token. ZKBallot transfers this token to the candidates’ clear handle, that means the identification of the candidate is understood.

Merely put, whereas the identification of the voter is unknown, it’s clear the place the vote went.

“We all know that some individual – which we don’t know [who] – has transferred a token into one of many candidates’ wallets, and we all know which candidate that’s for,” says Tewari.

ZKBallot is a free-to-use platform and doesn’t require any specialised {hardware} of software program to be put in by finish customers.

This TCD-created system solely works in closed environments, the place the identities and the precise variety of all of the voters is already identified – akin to boardrooms, golf equipment or college elections.

The platform, only a few days outdated, is but for use in any of those conditions, Tewari tells SiliconRepublic.com.

Whereas it is a smaller scale platform, Tewari argues that these may very well be utilized to a bigger inhabitants, akin to state-wide elections – nonetheless, not anytime quickly.

“There are mechanisms that we are able to make use of to generalise this for a a lot greater inhabitants whereby you could possibly have some form of a Zero-Data Proof given to every – let’s say – citizen[s] of the nation.

“And what they might do is that they’d use that Zero-Data Proof to show that they’re allowed to vote on this election with out revealing their identification,” he says.

One of these system is slowly gaining reputation with many trying to the blockchain for privacy-preserving functions. Furthermore, in response to Tewari, figuring out the precise variety of personal tokens issued additionally signifies that blockchain-led elections might negate cybersecurity and transparency dangers.

Elections in Eire are nonetheless solid on paper ballots. Whereas a number of international locations world wide have adopted e-voting through the years – a system which is broadly thought-about to cut back counting errors and poll tampering – sure issues nonetheless stay.

With newer, safer digital voting expertise on the rise, the query nonetheless stays on when Eire would possibly contemplating upgrading.
