“…Therefore, an excellent on-chain governance voting mechanism needs to consider anonymity. Currently, mixed network [42], group signature [43], and ring signature [44] can be used to achieve the anonymity of voting. • Coercion freeness: Coercion means an attacker requires a voter to vote for a particular candidate or abstain.…”

After the Ethereum DAO attack in 2016, which resulted in significant economic losses, blockchain governance has become a prominent research area. However, there is a lack of comprehensive and systematic literature review on blockchain governance. To deeply understand the process of blockchain governance and provide guidance for the future design of the blockchain governance model, we provide an in-depth review of blockchain governance. In this paper, first we introduce the consensus algorithms currently used in blockchain and relate them to governance theory. Second, we present the main content of off-chain governance and investigate two well-known off-chain governance projects. Third, we investigate four common on-chain governance voting techniques, then summarize the seven attributes that the on-chain governance voting process should meet, and finally analyze four well-known on-chain governance blockchain projects based on the previous research. We hope this survey will provide an in-depth insight into the potential development direction of blockchain governance and device future research agenda.

“…The scheme, however, still allows both the voters and the proxies to prove how they voted. The proposal in [24] ensures coercion resistance (which includes receipt-freeness) in proxy voting by extending the well-known JCJ scheme [25]. It, however, inherits the complexity of JCJ, and therefore, its problems with practical applications such as lack of efficiency and usability for the voters [26].…”

Proxy voting is a form of voting meant to support the voters who want to delegate their voting right to a trusted entity, the so-called proxy. Depending on the form of proxy voting, the proxy is either authorized to cast a ballot for the voting option that the voter chooses, or to vote according to her own wishes, if the voter is not sure how to vote and wants to delegate the decision making in the election. While the first form of proxy voting has been applied to traditional elections in order to support the voters who are unable to physically get to a polling station, the second form has been a topic of research in Internet voting. Recently, an Internet voting scheme has been proposed, that extends the well-known Helios scheme towards the functionality of proxy voting. This scheme, however, also has the drawbacks of Helios regarding participation privacy and receipt-freeness. As such, the information whether any voter participated in the election either by casting a direct vote or delegating their vote can be deduced from the published information. The scheme furthermore allows both the voters and the proxies to create receipts that prove casting a ballot for a specific candidate, as well as allows the voters to create receipts that prove delegating to a specific proxy. In this work we use the idea of dummy ballots, proposed in another extension of Helios to extend the proxy voting scheme towards participation privacy and receipt-freeness.

“…Norway has used an Internet-based voting protocol for some years, and the vote privacy and correctness of this scheme have been demonstrated [23]. In 2016, Kulyk et al [24] proposed a new coercion-resistant proxy voting scheme by extending the coercion-resistant JCJ/Civitas theme, aiming to prevent direct voter coercion, delegation coercion, and proxy coercion. They also proposed a new proxy voting scheme [25] to extend the Helios voting system [26] with delegated voting functionality.…”

Design and Implementation of a Mobile Voting System Using a Novel Oblivious and Proxy Signature

Electronic voting systems can make the voting process much more convenient. However, in such systems, if a server signs blank votes before users vote, it may cause undue multivoting. Furthermore, if users vote before the signing of the server, voting information will be leaked to the server and may be compromised. Blind signatures could be used to prevent leaking voting information from the server; however, malicious users could produce noncandidate signatures for illegal usage at that time or in the future. To overcome these problems, this paper proposes a novel oblivious signature scheme with a proxy signature function to satisfy security requirements such as information protection, personal privacy, and message verification and to ensure that no one can cheat other users (including the server). We propose an electronic voting system based on the proposed oblivious and proxy signature scheme and implement this scheme in a smartphone application to allow users to vote securely and conveniently. Security analyses and performance comparisons are provided to show the capability and efficiency of the proposed scheme.
