Geneer Labs has developed blockchain-based voting application Devote that provides true anonymity. True anonymity means that there no (even theoretical) chance for anyone except the voter themselves to know what their vote was for.
This application is based on advanced cryptographic protocol SAVER (SNARKs-friendly Additively-homomorphic protocol with Verifiable Encryption and Rerandomization), implemented by the team of Nil Foundation (nil.foundation). To make everything work, Geneer integrated the cryptography with a number of services (user verification, campaign managers interfaces, secrets storage etc), along with implementation of smart contracts.
Devote earned strong attention from a number of potential voting campaigns providers and successfully passed operational assessment by Government Blockchain Association, according to their BMM methodology https://gbaglobal.org/ru/blog/2024/06/07/devote-awarded-government-blockchain-association-gba-blockchain-maturity-model-bmm-assessment-level-one/
