Zk-SNARK

Match the correct parameters of each algorithm involved in zk-SNARK.

Verifier V

Verification key vk, public input x, proof

Prover P

Proving key pk, public input x, private witness w

Generator G

Lambda, program C

For a list of programs { C1, C2, C3 }. How many times does a trusted setup needs to be done?

What happens if the toxic waste becomes public?

The algorithms become polluted.

The verifier cannot verify the proofs

The prover cannot create the proofs

Fake proofs can be generated.

How do we increase trust in the trusted setup process?

By removing the malicious parties

By removing all secrets from the process of trusted setup and making everything public

By increasing the number of involved parties in the trusted setup

By decreasing the number of involved parties and keeping only one owner who does the trusted setup

How is succinctness achieved whilst creating a SNARK proof?

By keeping the proof size small

By choosing a few points where to check the polynomials t(x)h(x) = w(x)v(x)

By choosing a specific point where to check the polynomials t(x)h(x) = w(x)v(x)

By converting the polynomials into quadratic polynomials

How is the zero-knowledge aspect covered in the creation of a SNARK proof?

By using the homomorphic properties of the polynomial structure

By multiplying the polynomial equation with a public factor k on both sides of the equation

By hiding the actual values of the polynomials

By multiplying the polynomial equation with a random secret k on both sides of the equation
