Must have:

- Knowledge of the basics of cryptography, including common digest and signature algorithms, sparse merkle trees,

- Good understanding of Zero-Knowledge Proofs. Experience in writing Circuits. Understanding how the circuit’s code translates to proving time and memory complexity of the output.


Ideally would have:

- Experience in writing ZK circuits on Circom

- Knowledge or experience in implementing Multiparty Computation applications (if you’re good at MPC but not at ZKPs, still reach out to us!)
