Lite-PoT: Practical Powers-of-Tau Setup Ceremony

Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) schemes have gained significant adoption in privacy-preserving applications, in decentralized systems (e.g., blockchain), and in verifiable computation due to their efficiency. However, the most efficient zk-SNARKs often rely on a one-time trusted setup to generate public parameters, often known as the ''Powers of Tau'' (PoT) string. The leakage of the secret parameter τ in the string would allow attackers to generate false proofs, compromising the soundness of all zk-SNARK systems built on it.
