Svmuu reported that Ethereum co-founder Vitalik Buterin recommended the "The Interfold" project in a post, stating that more people should learn about Interfold. It is a general implementation version of the MACI (Minimal Anti-Collusion Infrastructure) concept he has repeatedly called for over the past decade. Essentially, this project is 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 stated that the core mechanisms of Interfold 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 ensures correctness through ZK over FHE, among other strong security guarantees. The main limitation at present is the high cost of complex computations (such as multiplication operations); only additive vote counting is mature. Optimizations based on slashing are being advanced, with a long-term goal of implementing obfuscation techniques to eliminate reliance on M-of-N committees.
