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) for end-to-end verifiable mobile voting, into its election technology platform. This move makes Sequent the first publicly declared election technology provider to integrate the VoteSecure framework, which was developed by Free & Fair and released in November 2025 after 16 months of research aligned with the U.S. Vote Foundation's "Future of Voting" report.
The milestone comes amid growing global concerns over trust, transparency, and confidence in electoral processes. VoteSecure combines cryptographic technologies already embedded in Sequent's platform to enable end-to-end verifiable elections, allowing voters, observers, and auditors to verify that every ballot was correctly cast, recorded, and counted. The protocol supports multi-factor authentication, biometric identity verification, and air-gapped tabulation, where votes are tabulated only after being taken offline from the internet, with paper printouts generated for traditional audit trails.
“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 of the protocol 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 platform, which has supported over 330 elections and served more than 9.2 million voters across North America, Europe, and Asia, is built on principles of transparency and cryptographic verifiability. Unlike traditional "black box" election technologies that rely on institutional trust, the VoteSecure framework uses publicly auditable cryptographic protocols, including threshold cryptography, verifiable shuffling, zero-knowledge proofs, and air-gapped tabulation. These techniques aim to strengthen election integrity while maintaining 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 today 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. Sequent's implementation of these protocols is seen as a significant step toward verifiable digital elections in the U.S., addressing the growing demand for transparency and auditability in electoral processes.
