Sequent, a global leader in cryptographically secured digital election platforms, announced it has advanced the implementation of VoteSecure, an open-source software development kit designed for end-to-end verifiable mobile voting. The milestone positions Sequent as the first publicly declared election technology provider to integrate the protocol into its platform, addressing declining confidence in democratic processes and growing demands for transparency.
VoteSecure protocols, developed by Free & Fair and released in November 2025, enable end-to-end verifiable elections by producing cryptographically verifiable evidence at every critical step, from voter eligibility to ballot casting and counting. The framework incorporates multi-factor authentication, biometric identity verification, and air-gapped tabulation, where votes are tabulated offline with paper printouts generated to complement traditional ballot channels. This architecture aims to provide a level of transparency and auditability that paper-based systems alone cannot achieve.
“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 centered on transparency and cryptographic verifiability. Having supported over 330 elections and served more than 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, VoteSecure relies on publicly auditable cryptographic protocols and open-source transparency principles, including threshold cryptography, verifiable shuffling, zero-knowledge proofs, and air-gapped tabulation environments.
The framework also employs Rigorous Digital Engineering (RDE), a formal model-based methodology focused on analyzable specifications and high-assurance software development practices typical of 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 infrastructure will play a major role in rebuilding confidence in democratic processes.”
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. The original release is available on NewMediaWire.
