The Ballot is Busted Before the Blockchain
As faithful blog readers, you've figured out that we are concerned about online voting apps, particularly unverified systems being pushed with the smokescreen of "blockchain" as the miracle cure to the security issues around internet voting. The Blockchain Papers series was created with the aim of collecting expert statements on this topic.
Here is the latest contribution to the series - no less than an actual security analysis of a certain blockchain system, Voatz, executed by a group of experts from the Massachusetts Institute of Technology (MIT). You will find this analysis fascinating; in particular, the exposure of the use of third parties for voter authentication and the potential privacy violations that may ensue. The privacy risk to the voter, compared to other voting methods, is exponentially higher. Such risk, coupled with the lack of transparency, is enough to put an "Iowa chill" into anyone's bones. I invite you to read the report from Specter, Koppel and Wietzner; and the insightful articles published at the time of its release.
