Sequent, a global leader in cryptographically secured digital election platforms, announced today that 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. This milestone positions Sequent as the first publicly declared election technology provider to further the VoteSecure framework, addressing growing concerns around election trust, transparency, and auditability.
The announcement comes at a critical time when governments, unions, and other organizations conducting elections face declining confidence in democratic processes and increasing demands for transparency and verifiability. VoteSecure, combined with Sequent’s existing cryptographic technologies, aims to provide voters, election observers, and auditors with cryptographically verifiable evidence at every step of the election process—from voter eligibility through ballot casting to the counting of results. This offers a level of transparency that traditional paper-based systems alone cannot achieve.
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 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 after being taken offline from the internet, with paper printouts generated alongside digital records.
“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, cryptographic verifiability, and publicly auditable election infrastructure. 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 employs publicly auditable cryptographic protocols, including threshold cryptography, verifiable shuffling and decryption, zero-knowledge proofs, and air-gapped tabulation environments, to strengthen election integrity while preserving voter privacy.
The framework also incorporates 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, auditing, and integration by election technology providers, governments, and civic organizations worldwide. For more information, visit sequentech.io.
