Vitalik posted a recommendation for The Interfold: this is a privacy protocol optimized for scenarios such as voting and secret auctions

Ethereum co-founder Vitalik Buterin recommended the Interfold project, stating, "More people should learn about Interfold, which is a general implementation of the MACI (Minimal Anti-Collusion Infrastructure) concept that I have been advocating for nearly a decade. This project is essentially a privacy protocol optimized for scenarios such as voting and secret auctions, allowing more people to pay attention to and understand this technological advancement."

Vitalik also mentioned that the core mechanisms of Interfold include generating threshold encryption keys, users submitting votes on-chain with ZKP (Zero-Knowledge Proof) credentials, and threshold decryption after arbitrary computation in Fully Homomorphic Encryption (FHE), which can achieve unconditional voter anonymity, Ethereum-level censorship resistance, and ZK over FHE ensuring result correctness, among other strong security guarantees. The current main limitation is the high cost of complex computations (such as multiplication), with only addition-based voting being mature, and optimizations like slashing-based approaches are being advanced, with a long-term goal of implementing obfuscation techniques to eliminate M-of-N committee dependency.
