Groth16 verifier
Web2 days ago · To me, all zksnark protocols assume there is a program such f (x,w)=y, then this programm is converted to circuit c (x,w)=y. Both groth16 and plonk make some polynomials from the circuit. Next, Prover construct a proof that I know those polymonials and Verifier can verify the provers's claim.

WebAs we can see, Groth16 does not use the “knowledge of coefficient” (that requires in the proof two group elements for each polynomial) , but uses the secret field elements α, β to force A, B and C to use the same vector w. The other two secret field elements γ, δ are used to make the public input independent from the other witness components. WebGroth16.
