Vitalik Recommends "The Interfold" Project: A Universal Approach to MACI for Privacy Protocols

Odaily Odaily reports that Ethereum co-founder Vitalik Buterin has published a post recommending "The Interfold" project. He stated that more people should learn about Interfold, as it is a general-purpose implementation version of the MACI (Minimal Anti-Collusion Infrastructure) concept he has repeatedly called for building over the past decade. This project is essentially a privacy protocol optimized for scenarios like voting and sealed-bid auctions, allowing more people to pay attention to and understand this technological advancement.

Vitalik also noted that Interfold's core mechanisms include generating threshold encryption keys, users submitting votes on-chain with ZKP eligibility proofs, performing arbitrary computations within Fully Homomorphic Encryption (FHE) followed by threshold decryption. This enables unconditional voter anonymity, Ethereum-level censorship resistance, and result correctness ensured by ZK over FHE, among other strong security guarantees. Currently, the main limitation is the high cost of complex computations (such as multiplication operations), with only additive tallying being mature. Optimization efforts such as slashing-based approaches are underway, and the long-term goal is to implement obfuscation techniques to eliminate reliance on M-of-N committees.
