Electronic transformation of political systems has become a challenging task in recent years. Applying cryptography to voting and electoral processes is crucial for democracy. The lack of trust placed in Remote Electronic Voting (REV) systems poses the main obstacle to adoption. Transparency measures and additional public security tests (e.g., public intrusion tests), such as the publication of the source-code, actively contribute towards public verifiability, and hence, trust placed in REV systems. Serving as a transparent, immutable, and distributed ledger, Blockchains (BC) offer new benefits for REV. Instead of relying on a single, centralized authority, a system of distributed, equivalent authorities can be used. Further, BCs serve as a highly replicated, tamper-proof audit trail, which enables the verification of cryptographic proofs, crucial for REV.
