Overview

Interactive Proof Systems
The following zero-knowledge proof systems are currently supported by a frontend or backend provider:
Succinct Non-Interactive Arguments of Knowledge (zkSNARKs)
The following zero-knowledge proof systems may be supported by a frontend or backend provider in the future:
Succinct Non-interactive Oecumenical (Universal) aRguments of Knowledge (zkSNORKs)
Succinct (Scalable) Transparent ARguments of Knowledge (zkSTARKs)
The following provider implementations are either supported or are being considered at this time:

¹ ZoKrates is not currently supported but listed as a provider above as it would be interesting to complete this effort and support it.
Circuit Provider Interface
// ProverProvider provides a common interface to interact with zero-knowledge circuits
type ZKCircuitProvider interface {
	Compile(argv ...interface{}) (interface{}, error)
	ComputeWitness(artifacts map[string]interface{}, argv ...interface{}) (interface{}, error)
	ExportVerifier(verifyingKey string) (interface{}, error)
	Prove(prover, provingKey []byte, witness string) (interface{}, error)
	Setup(prover interface{}) (interface{}, interface{})
	Verify(proof, verifyingKey []byte, witness string) error
}
Note that not all of the above interface methods will be implemented by every provider.
