JSnark frameworkAn arithmetic circuit is quite simple. Typically, it consists of a set of wires and gates. For example, the function f(x1, x2, x3, x4) = (x1 * x2 + 5) * ((x3 + x4) * 6) can be computed by the following circuit:
total 12
input 0 # The one-input wire.
const-mul-0 in 1 <0> out 1 <1>
input 2
In an anonymous credential scheme there are three participants: issuer, user(prover), verifier.
Issuer creates a certificate to user which contains a list of user's attributes and issuer's signature(use BBS+ signature). This protocol is formally called credential issuance protocol.
The user who is in possession of that credential can selectively disclose some parts to some verifier. This protocol is formally called credential presentation protocol.
