Sequent is a next-generation online voting platform purposely built to ensure the highest level of confidence in digital elections for election managers, voters and auditors

Sequent’s three layers of confidence

Sequent, a next generation online voting platform, is purpose-built to address the imperative challenge at the core of digital elections: voter confidentiality, end-to-end vote verifiability, and complete system transparency. These three layers are critical to the integrity of any digital election.

Confidential Voting

End-to-end ballot encryption and state-of-the-art cybersecurity measures guarantee voter privacy and tamper-proof elections

Verifiable Election Results

Advanced cryptographic techniques provide verifiable proof that every vote is cast, recorded and counted correctly throughout the election process

Complete Transparency

Unique to the Sequent platform, Sequent’s core technology is open source, increasing the system’s reliability and trustworthiness through academic and election expert review and vetting

The software in an E2E-VIV system must be trusted to fulfill the system’s requirements. Making all development artifacts freely available as open source is an important step toward such trust.
