Vitalik recommends "The Interfold" project: A privacy protocol implementing a universal MACI solution

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

Vitalik also stated that the core mechanisms of Interfold include generating threshold encryption keys, users submitting votes with ZKP qualification proofs on-chain, performing arbitrary computations within Fully Homomorphic Encryption (FHE) followed by threshold decryption. This achieves strong security guarantees such as unconditional voter anonymity, Ethereum-level censorship resistance, and ZK over FHE ensuring result correctness. The main current limitation is the high cost of complex computations (such as multiplication operations), with only additive vote counting being mature. Optimization efforts like slashing-based mechanisms are underway, with a long-term goal of implementing obfuscation technology to eliminate reliance on M-of-N committees.
