Sequent, a global leader in cryptographically secured, verifiable digital election platforms, today announced it has advanced the implementation of VoteSecure, an open-source software development kit (SDK) designed to enable end-to-end verifiable mobile voting, into its election technology platform. The milestone arrives at a pivotal moment as governments, unions, and other organizations conducting elections grapple with declining confidence in democratic processes and growing demand for greater transparency and verifiability.
VoteSecure protocols, combined with cryptographic technologies already embedded throughout Sequent’s platform, address concerns surrounding election trust, transparency, and auditability. The protocol enables end-to-end verifiable elections, allowing voters, election observers, and auditors to ensure that every ballot was correctly cast, recorded, and counted, and that election results are accurate. This provides a level of transparency and verifiability that traditional paper-based systems alone cannot offer.
The VoteSecure protocols were developed by Free & Fair, a credible voting technology research company, and released in November 2025 after 16 months of research and development aligned with the roadmap outlined in the U.S. Vote Foundation’s “Future of Voting” report. The framework supports multi-factor authentication, biometric identity verification, and air-gapped tabulation, meaning votes are tabulated only once taken offline from the internet, with paper printouts generated to accompany traditional ballot channels.
“We are at an inflection point in democratic history. Voters are asking whether their voices truly count, and election administrators are asking how to prove it,” said Shai Bargil, CEO and Co-Founder of Sequent. “The VoteSecure protocol helps to answer both questions with mathematical certainty. Our implementation represents an important advancement for election technology in the U.S. because it moves electoral processes closer toward open, independently auditable, and cryptographically verifiable elections.”
Sequent’s implementation builds on a global platform already designed around transparency, cryptographic verifiability, and publicly auditable election infrastructure. Having supported more than 330 elections and served more than 9.2 million voters across North America, Europe, and Asia, Sequent is helping translate VoteSecure’s work from a technical specification into real-world election infrastructure engineered for the future of verifiable digital elections in the U.S.
Unlike traditional “black box” election technologies that rely heavily on institutional trust, the VoteSecure framework is designed around publicly auditable cryptographic protocols and open-source transparency principles. The architecture incorporates threshold cryptography, verifiable shuffling and decryption techniques, zero-knowledge proofs, and air-gapped tabulation environments to strengthen election integrity while maintaining voter privacy. The framework also relied on Rigorous Digital Engineering (RDE), a formal model-based systems engineering methodology focused on analyzable specifications, formal verification, and high-assurance software development practices commonly associated with critical infrastructure and national security systems.
“Election integrity can no longer rely solely on blind trust,” added Bargil. “Modern election systems must provide verifiable evidence that votes were securely cast, accurately recorded, and properly counted. Open standards and publicly auditable election infrastructure will play a major role in rebuilding confidence in democratic processes over the coming decade.” The VoteSecure protocols are open source and publicly available for review, auditing, and integration by election technology providers, governments, and civic organizations worldwide.
