Types

type ConversionProofVer1ToVer2 

type ConversionProofVer1ToVer2 struct {
	Version uint8
	// contains filtered or unexported fields
}

For conversion proof, its version will be counted down from 255 -> 0 It should contain inputCoins of v1 and outputCoins of v2 because it convert v1 to v2

func (*ConversionProofVer1ToVer2) SetInputCoins 

func (proof *ConversionProofVer1ToVer2) SetInputCoins(v []coin.PlainCoin) error

InputCoins should be all ver1, else it would crash

func (*ConversionProofVer1ToVer2) SetOutputCoins 

func (proof *ConversionProofVer1ToVer2) SetOutputCoins(v []coin.Coin) error

v should be all coinv2 or else it would crash

func (ConversionProofVer1ToVer2) Verify 

func (proof ConversionProofVer1ToVer2) Verify(boolParams map[string]bool, pubKey key.PublicKey, fee uint64, shardID byte, tokenID *common.Hash, additionalData interface{}) (bool, error)

func (ConversionProofVer1ToVer2) VerifyV2 

func (proof ConversionProofVer1ToVer2) VerifyV2(vEnv env.ValidationEnviroment, fee uint64) (bool, error)

type PaymentProofV2 

type PaymentProofV2 struct {
	Version uint8
	// contains filtered or unexported fields
}

PaymentProofV2 contains the input & output coins, along with the Bulletproofs for output coin range. This is what shows up in a transaction's Proof field.

func Prove 

func Prove(inputCoins []coin.PlainCoin, outputCoins []*coin.CoinV2, sharedSecrets []*operation.Point, hasConfidentialAsset bool, paymentInfo []*key.PaymentInfo) (*PaymentProofV2, error)

Prove returns the payment proof object. It generates Bulletproofs for output commitments, then conceals sensitive information in the coins. The parameter hasConfidentialAsset will determine the type of Bulletproof prover to use.

func (PaymentProofV2) Bytes 

func (proof PaymentProofV2) Bytes() []byte

Bytes does byte serialization for this payment proof

func (PaymentProofV2) GetAggregatedRangeProof 

func (proof PaymentProofV2) GetAggregatedRangeProof() agg_interface.AggregatedRangeProof

GetAggregatedRangeProof returns the Bulletproof in this, but as a generic range proof object.

func (PaymentProofV2) GetInputCoins 

func (proof PaymentProofV2) GetInputCoins() []coin.PlainCoin

GetInputCoins is the getter for input coins.

func (PaymentProofV2) GetOutputCoins 

func (proof PaymentProofV2) GetOutputCoins() []coin.Coin

GetOutputCoins is the getter for output coins.

func (*PaymentProofV2) GetVersion 

func (proof *PaymentProofV2) GetVersion() uint8

func (*PaymentProofV2) Init 

func (proof *PaymentProofV2) Init()

Init allocates and zeroes all fields in this proof.

func (*PaymentProofV2) IsConfidentialAsset 

func (proof *PaymentProofV2) IsConfidentialAsset() (bool, error)

IsConfidentialAsset returns true if this is a Confidential Asset transaction (all coins in it must have asset tag field). An error means the proof is simply invalid. After this function returns, check the error first.

func (*PaymentProofV2) IsPrivacy 

func (proof *PaymentProofV2) IsPrivacy() bool

IsPrivacy is a helper that returns true when an output is encrypted, which means the transaction is of "privacy" type. It says nothing about the validity of this proof.

This is not a tight classifier between "privacy" and "non-privacy", and should not be called before sanity check.

func (PaymentProofV2) MarshalJSON 

func (proof PaymentProofV2) MarshalJSON() ([]byte, error)

MarshalJSON implements JSON Marshaller

func (*PaymentProofV2) SetAggregatedRangeProof 

func (proof *PaymentProofV2) SetAggregatedRangeProof(aggregatedRangeProof *bulletproofs.AggregatedRangeProof)

func (*PaymentProofV2) SetBytes 

func (proof *PaymentProofV2) SetBytes(proofbytes []byte) *errhandler.PrivacyError

SetBytes does byte deserialization for this payment proof

func (*PaymentProofV2) SetInputCoins 

func (proof *PaymentProofV2) SetInputCoins(v []coin.PlainCoin) error

func (*PaymentProofV2) SetOutputCoins 

func (proof *PaymentProofV2) SetOutputCoins(v []coin.Coin) error

v should be all coinv2 or else it would crash

func (*PaymentProofV2) SetOutputCoinsV2 

func (proof *PaymentProofV2) SetOutputCoinsV2(v []*coin.CoinV2) error

func (*PaymentProofV2) SetVersion 

func (proof *PaymentProofV2) SetVersion()

func (*PaymentProofV2) UnmarshalJSON 

func (proof *PaymentProofV2) UnmarshalJSON(data []byte) error

UnmarshalJSON implements JSON Unmarshaller

func (PaymentProofV2) ValidateSanity 

func (proof PaymentProofV2) ValidateSanity(vEnv env.ValidationEnviroment) (bool, error)

ValidateSanity performs sanity check for this proof. The input parameter is ingored.

func (PaymentProofV2) Verify 

func (proof PaymentProofV2) Verify(boolParams map[string]bool, _ key.PublicKey, _ uint64, _ byte, _ *common.Hash, _ interface{}) (bool, error)

Verify performs verification on this payment proof. It verifies the Bulletproof inside & checks for duplicates among outputs. It works with Bulletproof batching (in which case it skips that verification, since that is handled in batchTransaction struct).

func (PaymentProofV2) VerifyV2 

func (proof PaymentProofV2) VerifyV2(vEnv env.ValidationEnviroment, fee uint64) (bool, error)

type PaymentV2Logger 

type PaymentV2Logger struct {
	Log common.Logger
}

func (*PaymentV2Logger) Init 

func (logger *PaymentV2Logger) Init(inst common.Logger)
