Blockchains Are Not Safe For Voting, Concludes NAP Report (nytimes.com) 106

The National Academies Press has released a 156-page report, called "Securing the Vote: Protecting American Democracy," concluding that blockchains are not safe for the U.S. election system. "While the notion of using a blockchain as an immutable ballot box may seem promising, blockchain technology does little to solve the fundamental security issues of elections, and indeed, blockchains introduce additional security vulnerabilities," the report states. "In particular, if malware on a voter's device alters a vote before it ever reaches a blockchain, the immutability of the blockchain fails to provide the desired integrity, and the voter may never know of the alteration."

The report goes on to say that "Blockchains do not provide the anonymity often ascribed to them." It continues: "In the particular context of elections, voters need to be authorized as eligible to vote and as not having cast more than one ballot in the particular election. Blockchains do not offer means for providing the necessary authorization. [...] If a blockchain is used, then cast ballots must be encrypted or otherwise anonymized to prevent coercion and vote-selling." The New York Times summarizes the findings: The cautiously worded report calls for conducting all federal, state and local elections on paper ballots by 2020. Its other top recommendation would require nationwide use of a specific form of routine postelection audit to ensure votes have been accurately counted. The panel did not offer a price tag for its recommended overhaul. New York University's Brennan Center has estimated that replacing aging voting machines over the next few years could cost well over $1 billion. The 156-page report [...] bemoans a rickety system compromised by insecure voting equipment and software whose vulnerabilities were exposed more than a decade ago and which are too often managed by officials with little training in cybersecurity.

Among its specific recommendations was a mainstay of election reformers: All elections should use human-readable paper ballots by 2020. Such systems are intended to assure voters that their vote was recorded accurately. They also create a lasting record of "voter intent" that can be used for reliable recounts, which may not be possible in systems that record votes electronically. [...] The panel also calls for all states to adopt a type of post-election audit that employs statistical analysis of ballots prior to results certification. Such "risk-limiting" audits are designed to uncover miscounts and vote tampering. Currently only three states mandate them.

    To say blockchain is inherently unsafe is like saying software is inherently unsafe, or anything else. Everything has pros and cons, but you evaluate the final implementation as secure or insecure. There are challenges in any medium.

      To say blockchain is inherently unsafe is like saying software is inherently unsafe

      Oh, you are so close to a breakthrough.

      When it comes to voting, blockchain, like software, IS inherently unsafe. If the main goal for voting security is maintaining the people's confidence in an election, the only system that will meet that standard is a system where people are actually keeping an eye on one another. And I mean physically watching one another. And that's the system we had in place before the advent of voting machines and election software. You had a room full of election judges from both sides, and they sat side-by-side checking in voters as they approached the voting booth and physically watched them put the ballot in the box. When the votes were counted, there was a whole bunch of people from both parties standing around keeping a close eye. When the ballots were sent for storage, one person from each party rode in the truck to drop them off after sealing the container - together - and signing off.

      It was trust, but verify. Was it possible to jigger with an election like that? Of course. But you had a list of names of people you could hold accountable at every step in the process. Electronic voting will never, ever be trusted. That is the effect of transparency.

        Now the way most US, Canadian, and UK elections are run, the paper vote is a two-step process.

        A) You go to a scrutineer to check your name off a PAPER list, they hand you a ballot with no identifying information on it
        B) You mark an X on the ballot, fold it in half or stick it in a privacy envelope and then stick it in a cardboard box with a hole on top.
