Can blockchain technology make online voting reliable?


America Presidential elections on Nov. 3 had been contentious to start with, however unfounded and inaccurate accusations of electoral fraud from the defeated President Trump forged a pall over the entire process. Daniel Hardman, chief architect and chief info safety officer at self-sovereign identification answer Evernym, thinks blockchain may assist voting on the whole going ahead.

“Principally, blockchain can present a method for voters to be reliably and securely registered to vote, after which when votes are forged, blockchain is usually a mechanism for proving that any person has the appropriate to vote, based mostly on their prior registration,” Hardman advised Cointelegraph. “Blockchain can present some options that will assist with auditing a vote in an election,” he added.

Republicans have been hesitant to simply accept a Biden win, regardless of the electoral faculty verifying the outcomes earlier in December. Rationale ranged from accusations of defective or manipulated voting machines to allegations of falsified ballots showing en masse at vital voting websites. None of those accusations, nevertheless, have stood up in court docket.

“The current stuff that we’ve seen with election challenges in Pennsylvania and Arizona and so forth — there are specific options of blockchain that will have made it attainable to do extra strong auditing,” Hardman mentioned. “You’d principally be capable to lay to relaxation any issues about tampering and issues like that.”

With public blockchains, comparable to Bitcoin’s (BTC) for instance, each transaction is recorded on an immutable public ledger, making audits extra foolproof and clear than centralized or paper-based processes. Making use of such know-how to voting may obtain comparable outcomes for votes.

Though the mannequin seems clear and unchangeable, how would authorities know if votes got here from residents who solely voted one time? “What you need is what’s referred to as end-to-end verification,” Hardman defined. “On the one aspect, the entrance aspect of it’s the registration half,” he mentioned, including:

“You could know that an individual can solely register one time and that implies that when any person is available in to register you do the issues that you’d do in a bodily election mechanism at this time, which is — you test the motive force’s license, you see if their image matches, their signature matches, all that form of stuff.”

Then, below the hood, the know-how ensures every particular person solely a single vote. “On the backend, you show that for any given registration, you’ll be able to forged precisely one vote,” Hardman mentioned.

A vastly complicated matter calling for various options based mostly on differing risk elements, a blockchain-involved voting system may embrace particular elements for stopping voter fraud and malware, comparable to biometric-based voter identification. “If you understand that, ya know, John Smith from 123 Major Avenue in Pennsylvania has a selected fingerprint, then it’s fairly arduous for any person else to forged a vote on his behalf,” Hardman defined.

That mentioned, what then stops governments and corporations from benefiting from such private info for monitoring and different usages? Hardman defined China and its COVID prevention measures for instance of privateness infringement. The nation has tracked its peoples’ temperatures, matched with their identities and places, he defined.

“Within the case of elections, what you want is to separate these two questions,” Hardman mentioned. “The query — is the occasion that is making an attempt to forged a vote approved to take action as a result of they have been prior registered within the system — is one query,” he famous. “The query ‘who is that this particular person,’ is a distinct query,” he defined, including:

“There are elements of an election the place you may need to ask each questions, however there are different elements the place you needn’t ask each, and in case you separate these, then you’ll be able to stop the federal government from doing that — from having form of an apocalyptic surveillance state that is aware of which vote you forged and once you forged it and stuff like that.”

A key to the issue? A blockchain know-how referred to as zero-knowledge proofs, in keeping with Hardman. Zero-knowledge proofs primarily confirm an individual’s identification with out truly revealing their personal knowledge. “You ask any person at registration time to strongly establish, you understand, who they’re, the place they reside and so forth, however on the time they forged their vote, what you ask them is to show that they’ve the privilege of casting the vote with out disclosing who they’re,” Hardman defined. “You additional ask them to show that their vote has not already been tracked within the system […] which ensures that you would be able to’t vote twice.”

Over the previous few years, blockchain has gained reputation for its usefulness in a variety of mainstream processes, such as supply chain activities.
