Interfold’s open‑source CRISP protocol uses homomorphic encryption, zero‑knowledge proofs and threshold cryptography to enable secret, receipt‑free voting for

Interfold unveiled CRISP, a new open‑source voting protocol that promises fully private, coercion‑resistant ballots on public blockchains. The system, launched in May 2026, combines fully homomorphic encryption, zero‑knowledge proofs and distributed threshold cryptography to keep votes secret while still allowing transparent tallying [1].

**Key takeaways**
- CRISP encrypts votes, tallies them while still encrypted, and only reveals the final result [1].
- Zero‑knowledge proofs verify voter eligibility and vote validity without exposing individual choices [1].
- Distributed threshold cryptography splits decryption keys among “Ciphernodes,” preventing any single operator from accessing raw votes [1].
- The protocol is receipt‑free, eliminating proof that a voter cast a particular ballot and thwarting coercion or vote‑buying schemes [1].
- Interfold operates the project without a native token; the code is publicly available on GitHub [1].

## How CRISP works

CRISP’s architecture rests on three cryptographic pillars. Fully homomorphic encryption (FHE) allows mathematical operations on encrypted data, meaning votes can be added together without ever being decrypted—a digital analogue of a sealed ballot box that counts its own contents. Zero‑knowledge proofs (ZKPs) then enable the system to confirm that each encrypted vote comes from an eligible participant and that the final tally is correct, all without revealing any individual vote. Finally, distributed threshold cryptography (DTC) spreads the decryption key across a network of incentivized node operators called Ciphernodes; only a threshold of these nodes can cooperate to decrypt the final result, removing reliance on a single trusted party.

The protocol also addresses known weaknesses in existing on‑chain voting methods. Traditional commit‑reveal schemes are vulnerable to manipulation during the reveal phase, while plain on‑chain voting leaves every vote publicly visible. By contrast, CRISP’s receipt‑free design means voters cannot produce evidence of how they voted, breaking the chain of coercion and vote‑buying. Its censorship‑resistant submission ensures votes cannot be selectively blocked, and the system supports anonymous participation, further protecting voter privacy.

## Why it matters

Privacy and resistance to coercion are critical challenges for decentralized autonomous organizations (DAOs) that rely on token‑holder voting. Current practices expose votes to public scrutiny, enabling social pressure and market manipulation. CRISP’s combination of FHE, ZKPs and DTC offers a technically robust solution that could redefine how digital governance is conducted, making secret ballots feasible on transparent blockchains. A live proof‑of‑concept demo is already accessible at crisp.enclave.gg, allowing developers and community members to evaluate the protocol firsthand. As Interfold positions the project as infrastructure rather than a financial product—evidenced by its lack of a native token and open‑source release—the protocol may serve as a foundational layer for broader applications of encrypted computation beyond voting.
