Types ¶
type AssetsProofMachine ¶
type AssetsProofMachine struct {
// This is the anonymity set PK in the paper, !(privkey == nil) => s_i = 0
// We don't use a privkey set because we are going to want to index by pubkey a lot
PubKeyAnonSet map[*ecdsa.PublicKey]*ecdsa.PrivateKey
BalanceRetreiver func(pubkey *ecdsa.PublicKey) (balance uint64, err error)
// contains filtered or unexported fields
}
AssetsProofMachine is the state machine that is used to create a privacy preserving proof of assets
func NewAssetsProofMachine ¶
func NewAssetsProofMachine(curve elliptic.Curve) (machine *AssetsProofMachine, err error)
NewAssetsProofMachine creates a new state machine for the asset proof. TODO: Use the anonymity set choosing from the paper to initialize
func (*AssetsProofMachine) CalculateAssetCommitment ¶
func (machine *AssetsProofMachine) CalculateAssetCommitment() (assetCommitment *zksigma.ECPoint, err error)
CalculateAssetCommitment calculates the commitment to the Z_Assets to Assets Are we sure on returning an ECPoint?
type BalProofMachine ¶
type BalProofMachine struct {
// contains filtered or unexported fields
}
BalProofMachine represents a single iteration of the proof of assets protocol, and is used to compute individual balance commitments, as well as calculate things like responses to challenges
func NewBalProofMachine ¶
func NewBalProofMachine(curve elliptic.Curve) (machine *BalProofMachine, err error)
NewBalProofMachine creates a new balance proof machine
func (*BalProofMachine) SResponse ¶
func (machine *BalProofMachine) SResponse(si bool) (rs *big.Int, err error)
SResponse generates the response r_(s_i) with the balance proof machine and si (s_i). The challenge must be set.
func (*BalProofMachine) SetChallenge ¶
func (machine *BalProofMachine) SetChallenge(ci *big.Int) (err error)
SetChallenge sets the challenge so we can generate responses
func (*BalProofMachine) SetPrivKey ¶
func (machine *BalProofMachine) SetPrivKey(privkey *ecdsa.PrivateKey) (err error)
SetPrivKey sets the private key for this iteration
