We initiate a formal investigation on the power of predictability for argument of knowledge systems for NP. Specifically, we consider private-coin argument systems where the answers of the prover can be predicted, given the private randomness of the verifier. We show that predictable arguments of knowledge (PAoK) can be made extremely laconic, with the prover sending a single bit, and assumed t...
