Legacy voting systems are expensive, inaccessible and vulnerable — creating barriers to secure digital participation.

Legacy voting systems are expensive, inaccessible and vulnerable — creating barriers to secure digital participation.

Only governments and large organizations can afford the technology needed to ensure election security, leaving billions without a viable digital citizen participation option and preventing recurrent voting.


This outdated model weakens democracies, highlighting the need for an alternative with a more advanced technological design.

Designed by Vocdoni, for everyone.

We believe that a truly fair voting system should be free from political, corporate, or centralized control.

We believe that a truly fair voting system should be free from political, corporate, or centralized control.

Since 2018, we provided blockchain-based voting to hundreds of organizations worldwide, including political parties, local governments, associations, sports clubs and DAOs.


Today, new cryptographic tools let us protect privacy and scale to millions of voters at once. So we decided to begin again, designing a voting protocol from scratch that could become the global gold standard for secure, private, and affordable voting.


DAVINCI ensures neutrality by operating on a decentralized infrastructure, where no single entity can manipulate, censor, or bias election results.


It is built as an unstoppable, autonomous voting protocol powered by zero-knowledge cryptography and decentralized infrastructure. By leveraging a token-driven model, DAVINCI becomes a truly autonomous and resilient governance solution.


But Vocdoni doesn’t own this protocol! We’re simply the catalysts. DAVINCI is an open-source and neutral voting system built for the world, and its future depends on collective work. Everyone is welcome to contribute, shape, and improve it.

Sequencers Generate the Encryption Key

A group of Sequencers work together to generate a Threshold Encryption Key on Ethereum.


This key ensures that votes remain private and can only be decrypted when a majority of Sequencers collaborate at the end of the voting process.


This guarantees security and prevents any single party from accessing the results prematurely.

Voting, as an important piece of governance, is a fundamental piece for a decentralised world. Being able to organise votings without having to trust in central parties at high scale, is a huge advance for humanity. Vocdoni is taking the last advances in crypto to make it happen.

I have been full-time in the blockchain industry for ten years. Since day one, trustless but verifiable voting has been one of the main talking points on non-financial applications that blockchains enable. The Vocdoni team is arguably the best equipped team to bring it to the masses.

FAQ

We've collected some common questions about DAVINCI. If your question isn't covered feel free to reach out on X, Discord or Farcaster.

What is DAVINCI Protocol?

DAVINCI (Decentralized Autonomous Voting Infrastructure with Cryptographic Integrity) is a neutral and unstoppable voting protocol designed for privacy, scalability, and security. It enables high-frequency, low-cost elections while ensuring transparency, censorship resistance, anti-coercion, and integrity. Built as a Layer 2 solution on Ethereum, DAVINCI ensures votes remain tamper-proof and trustless, eliminating central points of failure. Technically, DAVINCI relies on cryptographic methods such as zkSNARKs and threshold homomorphic encryption (ElGamal), ensuring votes remain private yet verifiable, preventing abuses such as vote-buying. The protocol also handles data availability via Ethereum data blobs (EIP-4844), making high-volume elections feasible without overwhelming the main blockchain. In summary, DAVINCI is the first solution that meets all the criteria for a universal voting protocol accessible to the masses.
