Sequent, a global leader in cryptographically secured digital election platforms, announced today that it has advanced the implementation of the VoteSecure protocol, an open-source software development kit (SDK) designed to enable end-to-end (E2E) verifiable mobile voting. The milestone comes at a critical time when declining confidence in democratic processes and growing demand for transparency are pressing election administrators worldwide.
The VoteSecure protocol, combined with cryptographic technologies already embedded in Sequent’s platform, addresses concerns about election trust, transparency, and auditability. Its architecture allows voters, election observers, and auditors to verify that every ballot was correctly cast, recorded, and counted, ensuring accurate election results. This level of verifiability goes beyond what traditional paper-based systems can offer.
Developed by Free & Fair, a reputable voting technology research company, VoteSecure was released in November 2025 following 16 months of research 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—where votes are counted only after being taken offline, with paper printouts generated alongside digital records.
“We are at an inflection point in democratic history,” said Shai Bargil, CEO and Co-Founder of Sequent. “Voters are asking whether their voices truly count, and election administrators are asking how to prove it. The VoteSecure protocol helps answer both questions with mathematical certainty.”
Sequent’s implementation builds on a platform already designed for transparency and cryptographic verifiability. Having supported more than 330 elections and served over 9.2 million voters across North America, Europe, and Asia, the company is translating VoteSecure from a technical specification into real-world election infrastructure for the future of verifiable digital elections in the U.S.
Unlike traditional “black box” election technologies that rely on institutional trust, VoteSecure is built around publicly auditable cryptographic protocols and open-source principles. It incorporates threshold cryptography, verifiable shuffling, zero-knowledge proofs, and air-gapped tabulation to strengthen election integrity while preserving voter privacy. The framework also relies on Rigorous Digital Engineering (RDE), a formal methodology 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.”
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 about Sequent, visit sequentech.io.
