Sequent, a global leader in cryptographically secured digital election platforms, today announced it has advanced the implementation of VoteSecure, an open-source software development kit designed to enable end-to-end verifiable mobile voting, into its election technology platform. The milestone arrives amid declining confidence in democratic processes and growing demand for greater transparency and verifiability in elections worldwide.
VoteSecure protocols, developed by Free & Fair and released in November 2025 following 16 months of research, enable end-to-end verifiable elections by producing cryptographically verifiable evidence at every critical step—from voter eligibility through ballot casting to the counting of results. The framework supports multi-factor authentication, biometric identity verification, and air-gapped tabulation, where votes are counted only after being taken offline, with paper printouts generated to accompany traditional ballot channels. This architecture allows voters, election observers, and auditors to ensure that every ballot was correctly cast, recorded, and counted, and that election results are accurate.
“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 platform already designed around transparency and cryptographic verifiability. Having supported more than 330 elections and served over 9.2 million voters across North America, Europe, and Asia, Sequent is translating VoteSecure from a technical specification into real-world election infrastructure. Unlike traditional “black box” election technologies that rely on institutional trust, VoteSecure is built on publicly auditable cryptographic protocols and open-source principles, incorporating threshold cryptography, verifiable shuffling, zero-knowledge proofs, and air-gapped tabulation to strengthen 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 used in 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 and integration by election technology providers, governments, and civic organizations worldwide. For more information, visit sequentech.io.
