<p><strong>TL;DR:</strong> Vocdoni leads the way in opensource <strong>decentralized voting technology, with hundreds of thousands of votes processed for +300 organizations</strong>, including City councils, Political parties, Cooperatives, Football clubs, Associations, opposition groups under repressive regimes and more! We accomplished this using a custom L1 blockchain designed specifically for voting. <strong>Now, we are building DAVINCI, a new public good voting protocol</strong> that ensures anonymous, anticoercion, verifiable, and accessible elections using zkSNARKs and Homomorphic Encryption. <strong>DAVINCI is the first solution that meets all the criteria for a universal voting protocol, covering a wide range of use cases: from gasless and anonymous offchain voting for DAOs, with the same guarantees as onchain voting, to national-level official elections.</strong></p><p><br></p><h2>Introducing DAVINCI: The future of voting on Ethereum</h2><p><strong>Modern voting systems (whether paper-based, centralized digital voting, or onchain) suffer from significant flaws</strong>, including high costs, limited accessibility, and vulnerabilities to manipulation, bias, and vote buying. Achieving the highest standards of election security and fairness remains costly and complex, leaving billions without a secure digital participation option. <strong>Recurrent, low-cost voting is crucial for democratic resilience, but the existing systems lack the necessary technological infrastructure to support it</strong>.</p><p><br></p><h3><strong>What is DAVINCI?</strong></h3><p><strong>DAVINCI</strong> (Decentralized Autonomous Voting Infrastructure for Non-Coercive Inclusion) is a new neutral and unstoppable voting protocol designed for <strong>privacy, scalability, and security</strong>. It enables <strong>high-frequency, low-cost elections</strong> while ensuring transparency, censorship resistance, anti-coercion, and integrity.</p><p><br></p><p>Built as a <strong>Layer 2 solution on Ethereum</strong>, DAVINCI ensures votes remain <strong>tamper-proof and trustless</strong>, eliminating central points of failure.</p><p><br></p><h3><strong>How DAVINCI Works</strong></h3><p>DAVINCI leverages <strong>zkSNARKs and threshold homomorphic encryption (ElGamal)</strong> to provide <strong>end-to-end verifiability, anticoercion and anonymity</strong>, allowing voters to participate <strong>without compromising privacy</strong>.</p><p><br></p><p>A <strong>distributed key generation (DKG) system</strong>, coordinated via smart contracts, secures encryption key creation while preventing manipulation. This ensures <strong>trustless election integrity</strong> without relying on any single entity.</p><p><br></p><h3><strong>Technology & Implementation</strong></h3><ul><li><strong>Privacy-Preserving Voting:</strong> Utilizes <strong>zkSNARKs</strong> for secure, anonymous voting with <strong>on-chain verifiability</strong>.</li><li><strong>Scalable & Efficient:</strong> Implements <strong>Gnark cryptographic libraries</strong> using <strong>BLS12-377 & BW6-761 curves</strong> for <strong>fast recursive vote aggregation</strong>.</li><li><strong>Ethereum Integration:</strong> Produces <strong>BN254 proofs</strong>, ensuring vote validity <strong>onchain</strong> with minimal computational overhead.</li><li><strong>Accessible & Decentralized:</strong> Designed to run on <strong>widely accessible hardware (64 GiB RAM)</strong>, making it easy for anyone to join the sequencer network without requiring specialized infrastructure.</li><li><strong>Flexible & Gasless:</strong> Supports <strong>various governance models</strong>, including <strong>DAO voting, national elections, and community polls</strong>, with an efficient <strong>off-chain computation model</strong>.</li></ul><p><br></p><h3><strong>Why DAVINCI?</strong></h3><p>DAVINCI is the <strong>only</strong> voting protocol that outperforms <strong>paper-based, centralized digital, and onchain voting</strong>. It meets the requirements for a <strong>universal voting solution</strong>.</p><p><a href="https://vocdoni.io" rel="noopener noreferrer" target="_blank"><img src="https://tomato-giant-grasshopper-196.mypinata.cloud/ipfs/bafybeihp67w6hzoog2e2ufgn44wqpin7i7l54wvin2sew2xxa3f36n3giu"></a></p><h3><br></h3><h3><strong>Roadmap & Next Steps</strong></h3><p><a href="https://vocdoni.io" rel="noopener noreferrer" target="_blank"><img src="https://tomato-giant-grasshopper-196.mypinata.cloud/ipfs/bafkreigqsitln2filgaid2s2kzmjorwxkamjs2bdfxjr4zcnqyauj3wiyy"></a></p><p><br></p><p>DAVINCI has completed its <strong>proof-of-concept</strong> phase and is now moving towards a <strong>testnet launch in Q2 2025</strong>.
